Hello! I want to add some _nuance_ to the discussion because of course there's plenty. Kerosene isn't the only fuel that these lanterns are capable of burning, and some options that are available now are less unpleasant for indoor use. And as a matter of fact, one of the things these are still useful for is emergency heat since they're putting out quite a lot. However, *not every fuel is safe to use in them* so my official advice is don't use these lanterns indoors at all. The room I film in is quite poorly ventilated without the HVAC system running so it was a pretty non-ideal situation, but the room smelled like an airport and my throat was getting irritated. It's unpleasant and makes me feel terrible for the millions of people who still rely on kerosene for their lighting fuel.
(also, to be clear, kerosene by itself isn't the problem - kerosene heaters are widely available, but modern designs can burn the fuel much more completely for a safer and much less unpleasant exhaust. These lanterns literally haven't changed since the 19th century)
The reason he heat up the air .
Cold air need more fuel to make a optimal burn.
So if you can heat it up so its stabel.
You need les oil to burn.
And if you can metain the same airflow .
Its stabel more the fire burn
This is the reason a car need to know how cold the air and how much air thare is
So the computer can inject fuel that it need
Worry about the people who do not have rights
Solar with led quite useful
Very good point
I've never been so adequately humbled by a high end Deez Nuts joke
Bofa deitz lanterns
The only reason I watched this was because I read this comment and had to see it
Bofa deez lanterns caught me off guard ngl
Damn, no references to the Baja Blast? I ain't a Mountain Dew fan but come on.
Bofa deitz lanters!
"We call ourselves Dietz Nuts"
This joke, my dear man of culture, deserves a Like and a Sub
@Valok oh i see ,
Thank you so much for explaining.
@Valok well, that is just wrong.
It is used as a setup joke like:
"do you smell updog?"
"Not much, you?"
absolutely subbed on this joke alone
I was still processing the first one when the second one dropped and I literally screamed. Truly a powerful combo move.
The gratuitous Reddit lingo 🤮
I used to be a candle designer. You mention the "self-trimming wick", but there's also another thing that influences how a candle wick burns.
We've all seen those dribbling candles so beloved of Hollywood horror film makers. However, you're probably also familiar with the "night light" candles which have a small wick inside a very wide candle. These burn for many hours and are (relatively) safe to leave burning in a sleeping room because of the very stable wide base and, more so, because the flame burns down inside the candlewax.
Let's take this further. Upscale the size of the candle so its diameter is 6 inches. This will also have the long burning characteristics of the night light. As you said, it's the vaporised candle that gets burnt and not the wick itself. So such a candle might burn for an incredibly number of hours. But there's even more to this.
If your candle is correctly designed, with the appropriate thickness of wick. Then the candle can be designed to either consume all of those six inches of way (for better economy) or, as was typically the case in a drafty medieval church or cathedral, to burn hollow. You want the candle to burn hollow, leaving a thin wall of wax to protect the flame from those drafts.
Now, if your candle flame is protected by that wall of unburnt way, it doesn't just prevent any risk of the flame being blown out, but the flame will burn brighter.
Of course, it is crucial to get the size of the wick and the width of the candle exactly right, as there needs to be enough space between the oxygen-consuming flame and the protective unburnt wax walls, else oxygen rich air won't get pulled down that hollow tube that burning your candle is creating. But, get these things correct and you have something so beloved of religions the world over, a sort of "eternal flame" burning in our medieval church or cathedral.
Next. Well, we all know that medieval churches and particularly cathedrals are decorated with the most beautiful religious carvings. Having a candle that burns hollow presented the designers with an opportunity to richly carve such scenes on the outside of these large candles. And, because the outer carved walls won't get consumed by burning the candle, the craftsmanship isn't sacrificed in the burning. Indeed, if the craftsman so wishes, he could use the light of the flame burning down inside the candle to illuminate the richly carved design from within. It's also possible to refill the empty tube with new wax and wick, to reuse the carved candle.
Such richly carved religious candles are still available in modern day Germany. While my own interest is that I designed similar carved candles for the high end tourist souvenir market, depicting carvings inspired by England's medieval cathedrals.
Returning to your fabulously informative series on lights and how they work. I can only say a heart-felt Thank You. I've learnt so much from you, and hope you won't mind my stealing a little of your light (pun intended) by adding this small piece.
Fascinating. Thank you!
You the candle man….
Thank you for your insight. Cheers!
Flawless comment etiquette
@manoman0 Why? I don't bite 😆
As a kid in the 60s growing up in the Adirondack mountains I used these a lot. Some of my cherished memories are those with those lamps as my light source, like ice fishing, walking on trails/paths, Splitting fire wood. I am in my 60s now and I still use them. Especially in the winter with snow on the ground at night and I have to either gather or split some firewood. The warm soft grow of the lamp and the glittery reflections of the snow are so calming and beautiful. I will often spend hours out side with my lamp as light just puddering around. There is a place for modern flashlights and I have some but there lights are often to bright, batteries have a relatively short life, sometimes hard to position the light where I need it. The lamps soft natural light if easier on my eyes, calming and soothing of my soul.
It is a wonderful light, and it feels very connected to the past.
The smell of these takes me back to my childhood, my family used to use these when the power went out, which back then happened a lot in the winter. Good times, we would read books and play board games. I have many fond memories of lying around near the woodstove with a lantern and candles burning for light while it snowed outside. Honestly one of my more cozy memories that I cherish. I actually was inspired to bust out my storm lantern and give it a good burn, just to make sure it still works.
Same here in the late 60's early 70's if I remember correctly .. oil embargo's etc..
this made my day. growing up in the 70's i remember plenty nor' easters causing power outtages where i lived, near the coast. you just helped some of my favorite memories come back too! playing games on the floor with the oil lamp besides us. cooking and eating by a lantern sitting on the middle of the table. sitting at the kitchen table looking outside watching a storm, loving the peace and quiet inside, but listening to the howl of the winds outside. little did we know it would become prized memories. then, of course all the times we went camping. :)
I did just that, we lost power during that big freeze and then the water went off (local problem at the well pump from frozen metal pipes). So we found the one hurricane lamp and had to scrounged to find fuel (found a bottle of forgotten tiki lamp fuel). Went on Amazon and purchased one of those knock offs. I feel like I should have bought an original Dietz now and even ordered some fuel. May have to find an original Dietz lamp just to have the best.
@John Arnold We had a Coleman mantle lamp too, but for whatever reason my parents usually reserved that for the kitchen. We used kerosene lamps and candles otherwise. This was back in the late 70s. I've been looking into getting some paraffin oil for my feuerhand lamp. it's supposed to be less stinky.
Bright .....I'm 76 and we never used kerosene lamps, we used gas mantle lamps, much brighter and cleaner.
I live in Texas, a few years ago we had a huge freeze. I lost power for about four days. It was freezing, but luckily I had a cheap hurricane lamp (cracker barrelesqe). It made a surprising amount of heat and I was thankful for it!
We lived through that freeze in Texas too. Not only were we out of power but our city water system came crashing down. Strange couple of weeks!
Hows the freeze going again?
@Mario Luigi the exhaust files from a hurricane lame is approximately the same as 5 candles but provided 10x the light and far far more heat
The freeze is why I picked one up, along with battery powered camping lanterns. Was thinking of getting Sterno cans for heat but I'm going with Crisco instead.
@Eric yeah and that's why you don't run a car for long inside a garage. It's got exhaust fumes
This was a particularly excellent video.
Probably because you both have a similar way of expressing very interesting information, it's a very oddly calm strait forward manor, but yet it's very easy to listen because of how calm the voice is, you both give out information in a very easy to grasp pace, it's what makes you one of the best science based channels, clearly you educate the way you do because it's how apparently like to take in info, you like this video because the way the person is talking is very close to how you talk, easy to listen to and easy to indulge in
@Orkhiss I was all prepared to cringe hard, in fact I was starting to, but then I remembered the health problems which come with fire. It's funny you should mention oxygen delivery to the brain, because a few hundred PPM excess CO2 - not anything worse - stomps so hard on oxygen uptake that brain function can be halved or worse. Even without fire, bedrooms commonly build up more than enough CO2 to halve brain function. I'm not going to speculate about solutions because I've only just opened my window this morning... :)
I really glad that Eddie Munster has been successful in his adult life
@intrepidOlivia nothing, electricity has ruined society
I thought it sucked ass compared to his others
Ben Eater, Digital Technology indicated he got a notification from you on a topic he discussed. He, in turn, encouraged people to check out your channel. So I searched your topics.
I have loved and appreciated “hurricane lanterns” for many years and always wanted to know more about them. I was enthralled by this video and absolutely loved your thoroughness of details, teaching method and examples used. I kept thinking how awesome your teaching would be for my grandson when he gets to a school age in the near future. Although you have a number of Subscribers, now me as well, I wonder if you have ever thought of making another “children’s version” of your topics?
Thank you for your interest in teaching “unknown” things to others. BTW I enjoyed your “out takes”.
If you keep the lamp flame to about 1" in height, you won't get soot or smoke. When I start a lamp, I turn the flame down low, because as soon as you put the chimney on, the flame gets bigger and sometimes smokey.
I collect oil/kerosene lamps, and really enjoyed watching this video. :-)
I do too. I love them. I can't have any more though, my shelves are full up
The level of awesomeness in these videos has gone off the scales. Better than anything on syndicated shows.
This was VERY interesting AND entertaining!! I love the format and the way that you explain things.
I can’t wait to dive into the rest of your content!!
Great to see your T-shirt with the BBC test card F design introduced in Britain for the start of colour TV broadcasts there in 1967. And a great video too on oil lamps. By the way, the term "paraffin" is often applied to linear chain petreoleum distillates (carbon atoms in a chain with the hydrogen atoms branching off at right angles) as opposed to the aromatic configuration of carbon atoms in a hexagonal arrangement.
Never have thought that I would watch a half an hour video about lanterns and be fascinated by every minute of it. Subbed.
I've always been interested in mechanical engineering and I'd have never known there was so much detailed design work that went into a prosaic hurricane lantern. I wish you would have discussed the pump-up white gasoline lanterns with the mantles. I've never figured out exactly how they work. I would think if you carbureted the gas, it would blow up
He does in the next video.
He did that in another video (this video became the first in a three video series). They pressurized the tank so that the fuel would rise up the tube, and then use the heat of the mantles to boil the fuel so that it could be burnt with something resembling a stove burner or Bunsen burner.
@occam raiser we call it a blue flame paraffin torch here. Used to heat up a soldering iron as well...
@Nel Hanekom An identical approach was used in paraffin paint-burners ( up to about 1970/1980s) used to remove paint from wood prior to repainting in the days before noxious chemical strippers.
check out brass primus stove -the pressure makes it vaporize by using a carburetor like jet. It burns blue hot like household gas
Switzerland here. Thanks for that very interesting clip! At the age of 14-18 I had to feed some livestock every evening during winter time. One of our cowsheds was somewhat remote and had no electricity. So I lit up the place with a lantern. (Sturmlaterne) There was an iron pan with a hook in its middle on the wooden ceiling to place it safely. That was some 30 years ago. The cowshed is still standing and not connected to the electrical power, but its not used anymore.
I had a slow day at work today and I randomly got sucked into this watching this entire series on lanterns through my recommended, and I wanted to come back to this first one to say I never could have imagined I would be so captivated by the rich(, and in some parts of the world still developing) history of fuel burning lamps of all things. You're an amazing presenter. I never would have made it this far otherwise, and I'm glad to have learned something new. The bofa Dietz lanterns joke alone was worth the sub.
I have an heirloom kerosene lamp, when the power goes out for more than a few hours (which has happened frequently in windstorms, especially that time the power lines took fire). Yes, it does smell bad and get hot. But, we didn't need to refill it for years and it brought a comfort to being at home in the dark for 2 days when put high up in the living room for reading by/ general navigation (one of the few times I like an open floor plan) and moved to the bathroom or hallway as it became late so you could find the toilet or the sink, with the window open. I may have been able to take a shower this way once, even. It made a lot more light than the candles we reserved for the mostly useless kitchen and it not being bright in there discouraged you from wandering in and opening the fridge.
I inherited a old oil lamp that my Grandmother kept in her storm cellar, still had oil in it, but when I lit it there was heavy soot and odor. So I bought new lamp oil and new wick, cleaned out the old and it works great. It will still smoke a little if you turn the wick up to high.
Clean, rewick get fresh fuel. We use 2 in off grid cabin all summer. Must use pure K1 lamp grade
“My lamp runs on jet fuel” sounds a lot cooler than it actually is.
@Unconventional Ideas All three, Kerosene, Diesel fuel und Jet-A types are really close. If you look at specs, Jet-A actually has the most defined specs and smallest tolerances. But after all it is like more refined Diesel. For example has Jet-A a ignition temperatur at about 210 °C while Diesel is somewhere at about 230 °C I think. One of the major differences also is the freezing point, which is around -47 °C for Jet-A and about -20 °C for Diesel. Additives may make large differences here. Of the three Kerosene is the simplest and least specific. The freezing point may be all over the place. while the ignition temerature would be quite close to Diesel.
At ground level, with variations in compression and nozzles, you would get both piston engines and turbines to run on all three. Up in the air at cold temperatures you may see an issue with that. By the way, that is also why some tank engines can be run on different fuels. (For a Leopard 2 engine we jokingly say runs on everything from fryer oil or salad oil to jet fuel.)
@Alexander Kupke Jet fuel is actually reasonably close. That's way there are still specs like the smoke point for Jet Fuel.
This is actually false.. it is not jet fuel. On multiple factors. Try burn rate to create thrust. Total failure. I don't know why he discredited himself to say that.
@Squelch's stuff 'n' things That sounds very Rastafarian...
@Mert Koçoğulları nice comparison😆
Those kinds of lamps were pretty common in the Finnish army when we were outside in the woods, however we did use non smelly fuels, also in a tent airflow was definitely better than indoors.
What a marvelous Channel. I love to know how things work. And you keep it interesting too!
Worth mentioning that 7 years earlier, in 1853, Jan Zeh & Ignacy Łukasiewicz (in Lviv) built first kerosene lamp and year later - founded first modern oil well.
Not sure how effective was their combustion, but that's a big piece of history of lanterns.
This was such an informative video, and I appreciate it so much because I have some oil lamps that I have not wanted to use because I was afraid to but when I watched how you did it at least I know how if I need it. And the facts are so interesting that I want to give them to my grandchildren so that they can learn about these forms of lighting. I think this is so amazing and I appreciate all the research and time you spent in sharing this with us! God bless you!
Absolutely fascinating, thank you from New Zealand. I used beautiful kerosene lamps on my yacht, and now the hurricane ones are used ashore.
"I've always had a fascination for these"
The entire basis of this channel and it's fantastic lol
I have something of a morbid fascination with Victor Rat Traps.
This channel has a habit of convincing me to buy things I never wanted.
Honestly, the ability to be so fascinated by everything around you just might be the best superpower out there.
@Ugly German Truths
"It's" is NOT a possessive pronoun.
The possessive neuter "its" - like the possessive pronouns "his" & "hers" - doesn't use an apostrophe.
The apostrophe is used in the contraction of "it is" - aka "it's" - as also with "he is" ("he's"), and she is ("she's").
Don't feel badly - I made the same mistake for DECADES - and I did a LOT of professional writing, editing, proofreading, etc - before someone explained it to me.
@LKDesign nope, "base of this channel and it is fantastic", the possessive pronoun makes no sense in the sentence.
"Allow me to fill you in on the Dietz." So many jokes, but this one is the best one for me.
I remember these lanterns very well because we still use them in the Swedish military to keep light in tents. I would guess the reason is that it produces a quite pleasant light that is bright enough for the fire-watch to be able to see but dim enough for the rest to be able to sleep comfortably. Maybe it's also easier to get a hold of kerosene than to replace flashlight batteries as well.
Well, batteries perform less per cold degree. They do not provide any heat.. And they need individual effort to fill their role.
As a person who specialized in maintenance of this lamps in the camping place i was in, i will say, refilling is easier through the wick hole than through the actual refilling hole, much wider space. Also depending on the quality of kerosene or other fuel you use, this will end up accumulating a little bit of sooth or some sort of residue near the top which could over time constrain the air flow more than ideal, but the spring it has to lift the lamp actually helps with the cleaning, since you could pull and release a few times without the glass for the bigger pieces of residue to fall on their own. Regarding smell, i will say it was pretty much fine, but it did trigger a bit of allergies for some kids.
For context, the rate we used them was roughly 6 hours a day, 2 nights a week almost all year round, and needed to do full clean and maintenance every 3 to 6 months. The camp i used to work in used them for roughly 40 to 50 years before we added lightbulbs to the cabins for safety and health reasons. I was in charge of their maintenance for roughtly 5 to 6 years.
My dad used a hurricane lantern on a wooden sled shaped float to mark the end of his salmon gillnet at night until his retirement in the 80’s. It was seemingly brighter and arguably more noticeable than the D-cell based flashlight bulb type lamps of the day.
It always amazed me that these worked so unfailingly well all those years along the coast of British Columbia given the environment and sea conditions.
Thanks for refreshing these memories.
I love your sense of humor and I learned a lot! The video was both informative and funny!
How am i just now learning i didn’t actually know how a freakin candle worked. Knew about the wax fuel but not the curling part.
Ahh but a great item to have for preppers and off grid living, camping....some heat is disappated to aid the cold hands.
I used to collect all sizes of these lamps..from knick knack two inch, functional versions to full size all option versions..country farm auctions always have a few fire items like the pump up gasoline blow torch which would spew a stream of flaming fuel until the nozzle was orange hot and then act as todays hand held torches.
Awesome history lesson, I thank you.
Never expected to see you of all people in the comments of a video unrelated from your own content
The "how to dow download more ram" guy
@ricardo lopez So many inventions were accidents. I wish someone would do a video on it. They think even the wheel was accident, from rolling logs.
We tend to think we are smarter than people of old. But if we were transported back in time, we could do next to nothing to improve tech. Can you make a computer? Can you make a light bulb? Do you know how to make gunpowder and where to get ingredients?
This is absolutely fascinating to me. I can remember my Dad's lantern as he walked home in the summer as he would spend the night at a tobacco barn curing bright leaf tobacco. No flashlight just his lantern. Memories from the late 1940s. No electricity until I was 3 yrs old. I still have 2 lamps and one of his lanterns. Thank you.
We had the dead flame lanterns when I was growing up in case power went out during storms. It definitely saved us when our city got hit with a blizzard for a week and the grid went down. The lanterns provided both light and a bit of warmth. It was a really poignant moment in my life, and to this day, my dad still has these lamps. Have a follow. The way you spoke was relaxing and informative. I also love the bloopers.
Well, that was very, very interesting. And I didn't know I was so interested in lanterns! Thank you so much. I'll definitely check out more of your channel's videos. Thanks again - very nicely done, indeed.
I am old enough to remember when every household in my little community had a couple of these. We thought they were called "Hurricane Lamps" because the only time they were used was when the power went out, usually due to hurricanes or other really high winds! Thanks for the correction!
never thought these lanterns hid so much science behind their designs..we used to study by using these during power cuts. we do have one..i would surely try to light it..thanks for the awesome video😊
"we call ourselves Dietz nuts"
You, sir. Are this decades most important comedian.
I thank you for your continued service.
@Hugh Mungus Though it apparently took several takes before he could say it with a straight face.
I can't take anymore ...
@Dominique B. D and T often swap out for one another. Any word with either will be pronounced with the other somewhere or when. The most common pronounciation of Machester United on BBC sports broadcasts is "Machester Unydid". The German for Daughter is Tochter for instance, same root but a different pronounciation.
@Marc Fuchs a bit late to this battle, but i had a much more naive interpretation of his pun, which i think fits better the general gentle & family-oriented tone of his presentation -- i translated this as "we call ourselves 'these nuts'", nuts having the first meaning noted by Dennis Hall, of enthusiasts, or slightly crazy (in a good way) people. "Deez" is a common mispronunciation of "these".
Wow! That was the most fun I've had in awhile learning a historical tidbit about something I'd wondered about...lol. Thank you! I live "off grid - and use propane 'lamps', so I can't wait to hear what you'll share about the Aladdin lamp! Thanks again!
I love this guy, he brings out the inner nerd in me. What a great video, and I often wondered why they were always trimming wicks in novels, now I know. Cheers from the UK. Great T shirt, TV test card. Dietz, Amazon UK £56.58.
This was a very interesting and informative video. I'm glad that some random 6th graders decided to enter a contest (they won btw) and ended up inventing the Luci light. It's quite literally changed so many lives around the world mine included. It's a neat story. You should check it out.
As a bit of a pyromaniac who collects liquid fuel lights, heaters and stoves I was fascinated. I never thought through the reason for the hollow arms in a hurricane lamp - although they clearly were hollow. But interesting though the video was it was almost at the end that I noticed you wearing a teeshirt with the BBC Test-card on it that I grew up with when UK TV was migrating to UHF and colour......It completely made my day. Thanks.
I have used these when a hurricane knocked out my power for two weeks. These are very bright and come in handy. I love them and especially sitting on the back porch add a perfect light.
I am 76 years old, live on an island 140 kilometres off the north coast of British Columbia and frequently rely on lanterns which, up until now, i have done so in total ignorance. Thank you for this illuminating presentation.
I am 59..luckily raised by an "old father" who was a depression kid..I know ALL the old tricks..even the pour a quart of kerosene in a frozen engine at -45 the night before..it evaporates off after the engine DOES turn over..Today? "Kids" up to say 45 cant tell me how tall a tree is on a sunny day if i give them a measuring tape and a meter stick:)
How in the world did you end up there?
What most impressive is that you can get an internet connection in a relatively remote location.
This right here is exactly why I love youtube.
I have used these for years when camping & reenacting, also just for general outside use, but we use citronella as it keeps the mozzies away, especially in the Aussie outback
I have citronella candles for Scottish Midgies (it is too cold for Mosquitos up here.
Same goes here in 🇿🇦 for mozzies. I’ve many hung up outdoors as decorations seeing as I’ve LED lights for camping now, fixed on my Land Rover and they’re fed by a solar panel so they never need “filling”, but I’ve just realized that I’ve lost the mozzie fighting effect, that I get from a battery powered spray can. Could not believe that I watched the video to the end.
@USN Chief It is a mosquito. We have an abundance.
@USN Chief yeah I thought that too but the Australian outback is bone dry, it's a giant desert.. It has the same annual rainfall as Arizona.
@Mike Borrelli Mosquito?
I like this guy! He has a way of making this NOT boring. He is funny and makes me want to stay for awhile, because of his way of teaching boring and making it very interesting with a lil humor to make it all come together. Thanks!
Very interesting talk. Ive got my great grandfathers guard lamp from the L N E R, from I assume the 30’s. It looks very similar to the taller hurricane lamp. I also love the test card t shirt, very retro, such a square eyed kid that I was, I’d actually watch that waiting for play school to come on in the 70’s!
very interesting. love your British broadcasting test card t-shirt. Can't wait to hear about the nuclear fusion lamps :)
I watched this video again because it's cool lol. Anyways, I want to clarify something he said. Kerosene and Paraffin, sometimes people call Kerosene Paraffin. I burn Paraffin lamp oil in my lamps, it doesn't have any odor at all, that I can detect anyways. Kerosene has a noticable odor. So there is a huge difference between Kerosene and Paraffin lamp oil. Use the Paraffin. I'm a little surprised he didn't address this more.
@Stephen M. Stouter, LOL!!!
I only use good, pure whale oil
@IcePike No I have not. I wonder how well it would burn..
@IGIT AHIMSA have you used Paraffin lamp oil in a kerosene heater? I’ve never even thought about that till just now because I don’t have a kerosene heater. I’d really like to get one though.
Another lantern use: My dad was born in the Mojave Desert in 1916. If someone had to go outside at night, one lamp was sufficient for light, but they would carry two. One near each ankle. Rattle snakes would strike at warm temperatures, so they would strike the lanterns instead of people's legs.
As if the deathclaws were not threat enough.
Not even a single Fallout New Vegas reference
"Patrolling the Mojave....."
@pandorafalters yeah but they typically attempt to ambush. they're trying to get them WITHOUT having to chase. because at full speed, the mouse gets away. that's part of why these snakes are so dangerous, they're really quiet and hard to see, so we get way closer than we should. a mouse just dicking around looking for food isn't moving that quickly. most predators try NOT to get into chases, and most of them miss a lot.
@Kairu Hakubi And I was pointing out that "a _few_ inches per second" is a poor characterization of the actual speed of those "furry gumballs".
@pandorafalters my good man, I was describing the speed of the human's legs, and how weird it must seem to a critter much smaller to have something so big move past them at such a speed.
Knowledgeable and informative video. Excellent explanation of self-trimming wicks. Before the 1800s, servants would have the job of trimming the wicks on a regular basis. Incidentally, I remember the BBC image on your T-shirt. It was called a 'test card'. It was used in between TV programmes, and this one would appear for up to a couple of minutes between children's programmes.
We use these lanterns quite a lot on our boats. They're reliable, and flexible. They can provide light in the cabin when the electrics are working, they're a good heating source, and they're resilient enough to be hoisted into the mast or forestay to function as a light signal if the need develops.
I just disovered your channel recently, and I love it so much! I particularily enjoy the scope of technology that you talk about. From candles to "modern" technology, I learn so much. Kind of like Bill Nye the Science Guy for adults!
I have used those indoor table lamps in my childhood and it brings me some great fond memories. I used to light them whenever electricity connection goes off. I used to put kerosene into them and clean the glass kink sometimes. My affection for them arise from the concentration it gave me since there was dark everywhere and it's just the source which is lightning just near my books. I will surely buy one of them for the memories.
The deadpan “Dietz Nuts” joke had me pausing to 😂 😆 🤣
killed it with tht one
Damn, I'm right here in the exact position as you. Hahaha
Worth the sub.
Did you catch the "Bofa" joke after?
that one got me good, I didn't see it coming at all
I have two of these lanterns, and I love them. Very reliable, easy, portable and I even enjoy watching them burn. Thank you for this comprehensive and cool video.
I still keep four lamps like this ( which I found on my property and restored myself from my automotive and home renovation experiences ) around for emergency purposes. They are great lamps, and even old Tallow, Kerosene, 110+ year old Whale Oil ( also found on my property), and other fuel sources work great and give off great heat and useful light!
Coconuts are an unknown source in my part of Rural-Ohio! Will investigate this further!
Very interesting series! It has become even more interesting recently, as our electricity was off for nearly 5 days in December!
Very informative and definitely a learning experience, thank you for your research it was in the label we do have one of those lamps to this day the blue wind resistant flame and it works well
Have you covered true Aladdin lamps yet ? They were available in many styles until recently. The
mantle/vaporised fuel vs a straight fuel- to -wick comparison would be interesting.
It’s after midnight, I’m totally sober, I do not own any lanterns and have honestly never thought of lanterns in any way, yet I sat enthralled watching this entire video. Well done, sir.
It’s close to midnight, there’s something evil lurking in the dark, under the moonlight, you see something almost stops your heart
Same here, except it's quarter till midnight 😂
God Is Love, not lust which is sin. people can go to hell for scandal.
True. I am about 70+ years old now. Born in rural India, I have used pretty much all types of lamps that you have described. From lamps burning vegetable oil in terracotta devices using a wick made of rolled cotton, candles, and lamps using kerosine and also petronax lamps. But they are all inly memories. I remember those days when I was doing my arithmetic home work of addition and subtraction. Imagine with that beginning to a Ph. D in applied maths at the age of 28, well with electric lamp.
Great job. I've never though there were so many details about oil lamps. Thank you.
Used a couple of cheap hurricane lanterns from walmart in deer camp this past fall and they worked great! Bright and steady light outdoors, felt just like electric, and no fussing with brittle mantles of propane lanterns, although those are definitely brighter. One of them did spill inside a tent, so I wouldn't resort to that, but outside, around the bonfire they were great.
I have the blue No.8 and a galvanized No.2 made by W.T. Kirkman, both modern, and they are great. I use paraffin in one for indoors and kerosene in the other for camping. They are both great. The No.8's wide base makes it very hard to tip over. Thanks for the detailed breakdown of the function. 👍
Excellent presentation. Well researched facts , doubts clearly illustrated when found. Pros and Cons clearly and colourfully explained. I learnt a few things and was kept interested. Thanks. I subscribed and look forward to new content and catching up on your past videos.
Speaking of confusing names for hydrocarbons, in my language (Czech), Kerosene is known as "Petrolej", which sounds similar to Petroleum (i.e. crude oil), and Petrol, which in America is called Gasoline, often shortened to Gas, though it isn't actually gas but liquid, and we call that "Benzín", which is pronounced exactly like Benzene, but that's a different chemical substance, which we call just "Benzen". It's not to be confused with Benzine, which is another name for Petroleum Ether, which isn't really an Ether, because actual Ethers are hydrocarbon derivates, whilst Petroleum Ether is a petroleum fraction with a low boiling point, which is the real reason why it's called Ether - it's on a basis of similar physical property, rather than chemical similarity.
In German, where Gasoline is called "Benzin", Benzene is known as "Benzol", but in Czech "Benzol" actually means BTX, which is a mixture of Benzene, Toluene and Xylene. Regular Kerosene, like the one used in lamps is called "Petroleum" or "Petrol" in German, but aviation Kerosene, i.e. jet fuel, in German is "Kerosin".
In Czech, we also call diesel fuel "Nafta", which sounds like Naphtha, but isn't the same thing, Naphtha is actually a name sometimes used for White Gas, which isn't gas but liquid, isn't white but clear, and can mean three different things (see wikipedia), but most common one is a fluid used in camp stoves, lanterns or lighters or as a solvent. Closest thing to Naphtha we have in our language is "Technický benzín" (literally 'technical gasoline'), but don't confuse it with normal gasoline, because if you put it in a gasoline engine, it's not going to like it.
Naphtha, or White gas, also shouldn't be confused with White Spirit, a.k.a mineral turpentine which, surprise surprise, isn't really white or spirit, and is definitely not a turpentine (a distilled tree resin). We call it "Lakový Benzín" (literally 'varnish gasoline'), except it's not really a gasoline either. It's more like a paint thinner. If you want to know what we call paint thinner in Czech, it's "Ředidlo", which literally means "dilutant". Mind you, there are many different types of "Ředidlo" which I'm not going to list here...
Interestingly, in Poland (which is right next door from us), Kerosene is called "Nafta", and diesel fuel (remember that is what us Czechs call "Nafta"), is known as "Olej napędowy" (literally "driving oil"), or colloquially "Ropa", which in Czech actually means crude oil, but is sometimes used as a derogatory name for diesel fuel. Crude oil in Polish is "Ropa Naftowa". In case it wasn't confusing enough already...
Edit: i've had to make some corrections here and there because the nomenclature across languages is such god awful mess, I got lost in it myself. But at least we can make fun of it :D. Thank you for all the likes and replies.
In Swedish there's also "gasol" which is a mixture of light hydrocarbons like propane and butane. (The corresponding English language Wikipedia page is called Liquefied Petroleum Gas but I'm not sure I trust that it's a one to one translation)
Note that the stuff that is called Benzol in English is a mixture of Benzene and Toluene.
Benzol (in English) is a now discontinued product used in early engines instead of gasoline (before they started adding lead to gasoline). This substance was derived from coal tar, and its greatest claim to fame may be the role it played in the Halifax Explosion during WWI.
In Swedish, kerosene is called "fotogen", because it generates light. Even when we don't use it for lighting, e.g. "flygfotogen" (aviation kerosene).
7:52 I think I remember lamps like these from my childhood in the early 2000's. We would use them when we camped in a Prowler travel trailer. It was a pretty old, smelled like mothballs, but I loved staying there. These lamps were perfectly useable from what I remember. There was plenty of light to see and they were cooler than halogen or LED flashlights because who doesn't like an open flame? We didn't use them for very long, maybe they were gas mantle ones, I can't really remember
We used these cold blast lanterns nightly when anchored off the Maine coast aboard our 19th century windjammer in 2017. Although the vessel was modified to add electric lighting below, deck lights were done in this way because they attract fewer mosquitoes, for some unknown reason.
Hi Alec, I paused the video midway to google a bit more and in the process read the Wikipedia entry for kerosene lamps, including their info on Mr. Irwin's hot blast and cold blast designs, which included hyperlinks to the patents. You briefly show the cold blast patent at about 19:00.
Intrigued, I searched for "hurricane lantern patent" and discovered the familiar design shows up with Bruno Nier in Germany 1933/34, apparently combining a modified Irwin hot blast design (Pat. No. 89770) lantern with his cold blast burner design (Pat. No. 138654). The Nier U.S. Patent is 2004826. It was applied for in 1933, granted in 1935, and expired in 1952.
Meanwhile, we also know that the Dietz "Little Wizard" has been in production since the 1914.
It makes for a confusing history, since the Nier and Dietz designs are all but identical. With both being patented, it makes a person wonder who actually came up with the iconic design first, and if Nier was second, why no patent infringement case?
Either way, they're great lanterns, and we always had a pair at hand for use during power outages when I was growing up.
Thanks for awesome info, always great to see our next generation of society actually knowing useful knowledge most your age sit around playing video games. Keep learning and teaching, we need more like you. Personality and humor was great too
I was just thinking. I wish my kids would watch videos like this instead of the crap I keep telling them to turn off!
We still use these lamps in our military tents in Sweden. We had a malfunction on one lamp recently, the flame wasn't very stable and we had to constantly adjust the wick length, then it started to have a "secondary" flame that went kind-of sideways from the wick. When we tried to extinguish the flame by adjusting down the wick it just kept burning even though the wick was gone, so it was probably burning the fumes from the heated up kerosene (the lamp gets really hot). We had to lift the glass and blow it out. I saw that the deflector wasn't properly secured so it could draw in air there, but I don't really know how that could affect it. We fixed that and it worked, so I didn't think more about it until I saw your great video. :)
Speaking as someone who did industrial combustion for many years, pre-heating combustion air is actually something that is done because it increases the efficiency as well and allows for higher temperatures to be achieved. The reason being is that you don't have to heat the incoming air to the temperature you need which actually wastes heat energy. The reason you want a cold air intake into your car engine however is for the higher density that colder air contains which naturally also means more oxygen because your not trying to heat the engine. If your interested in learning more about pre-heating in combustion systems the term your want to look up is "regenerative combustion burner" as they can explain it much better than I can.
There is still confusion here. I started repairing cars and other vehicles in the 1960s and stopped in 2018 as a professional. After gasoline engines are at operating temperature, many stopped heating the air fuel mixture, This was before and after emission controls were added. Heating was done for fuel economy more than emission concerns. atomization may have improved, but if the air fuel ratio was around 14.7 to 1, the compression cycle added plenty of heat and turbulence to atomize for proper combustion. The factories were pressured to have clean exhaust and get good economy at the same time. They would lean mixtures as far as possible, the engines produce low power and often Hydrocarbons increased if everything wasn't perfect. Warmer intake temps caused higher oxides of nitrogen to be produced, which was a controlled emission gas. They added EGR systems that put exhaust into the fuel air mixture, not to heat it, but to add an inert substance that cooled combustion temps to lower the oxides of nitrogen. things got back on track when computers started controlling nearly everything and actually enriched the fuel air ratio so the catalytic converters could get hot enough to clean the exhaust. Best horsepower occurs with cool air and fuel. Of course if you look into Smokey Yunick's expander cycle engine, than all of the above means nothing. Maybe it's a hoax?
Lol I just commented theorizing the same thing lol guess I should have scrolled a little further down and seen someone who actually knew confirming my theory
@Krzysztof Kozłowski to the best of my knowledge, the pressure change due to temp only matters in regard to how much oxygen is actually in the cylinder, and thus how much fuel can be combusted. Conveniently, EFI engines pump fuel into the cylinders based on the manifold air pressure (or i'm pretty sure they do), which means that the higher pressure of colder air will also result in higher fuel pumped into the cylinders, and since that denser air does have enough oxygen to combust that extra fuel, you get more power.
As I long-windedly explain in my public comment, cold air intakes only became popular with multi port EFI engines. Prior to that, carbureted engines needed heated intake air in order to atomize fuel well enough to meet emissions standards.
I would add that engine analogy doesn't seem to really apply. As far as I can remember combustion engines use, at least in part, gas temperature (and thereby pressure) difference to generate torque. Cool running engine is more efficient. A lamp kept cooler isn't as it doesn't cycle.
I have a sneaking suspicion this was just throw away joke made before a real point. The comment is written, so I might just post it anyway.😅
In the ‘70s, we’d use these on the beach. They were wonderful lanterns. The maintenance was really, really low, which you’d not expect.
Great video. I'm curious if the "pre-warmed" air aids in keeping the oil tank ever-so-slightly warmer so that the viscosity of the fuel oil is decreased, allowing it to move up the wick easier, as well as preheating the burner assembly to allow the fuel to evaporate faster from the surface of the wick. Also, maybe you mentioned it and I'm forgetting, but I use paraffin lamp oil in my vintage cold blast lantern (Embury #30), as opposed to kerosene, and I cannot smell it all, even if it has been burning for hours indoor.
I'm 76 years old. My first few years growing up in the Missouri Ozarks was in a house lit by kerosene lamps, late 40s and early 50s. A couple sets of grandparents used these for a few more years. I still have a couple of these for when the electric power goes out. Thanks for the interesting presentation.
I love these videos. Always educational, thank you.
Although I was drawn to your t-shirt as it s a reminder of my child hood. In fact in a strange coincidence I’m watching an episode of QI on the BBC where it’s just come up. Apparently the girl on the T-shirt is called Carole Hersee. And she is the most broadcast person ever, at over 70,000 hours.
Not to take away from this cool video about lamps 🙂
I'm from Namibia, Africa. These lamps are still in daily use by us. It is still the "best" option in many areas compared to the available alternatives.
Thanks for a very interesting video.
@Josh Me I'm in the same area. But the use of kerosene heaters wasn't due to a lack of technology....It was due to the oil shortage - which resulted in higher heating fuel costs. We had one too - it was a temporary fad that people used to limit the use of their furnaces.
@Erik Willemsnerd alarm!
@Steve K Unfortunately kerosine is overpriced now.
@Baroudeur they're a great back up for outages like happened in Texas with the ice storm. I used one years ago as a space heater when kerosene was 99¢. At $5 it's better as a powerful backup. They use one gallon per day.
Amazing video! I learned a ton.
We used Dietz lanterns in a wilderness school I went too, they burned all night, every night, and had been in use since the 60's when the camp opened. Of course basic maintenance was done, wics, cleanings, new globes, etc, but those lanterns had hundreds of thousands of hours on them, and function just as well as the brand new one I have. They burned farm grade, dyed, kerosene. On low, the smell was tolerable in a smaller space, but on high they would start to smell. I use paraffin oil in mine now, and I can burn it inside on high no problem, it's also MUCH more clean. At the school, we cleaned the globes every few days, mine can go months or more between cleanings with the superior fuel. It costs more, but I'm also not burning it every night.
this was an excellent video, and I deeply appreciate this channel.
I literally don't think I knew what fire was until now.
I never thought I would watch a 31 minute video on a lantern, until today.
Right?!? Here I am too laying in bed. What's this? Hurricane lanterns? Let's watch.
So interesting, I had no idea about the history and function of the humble lantern....thank you!
I found this video by accident today (never knew about you before) and I must say, I learned a lot! Thank you so much!
These lamps were the only source light even 15 years back in my village when electric supply wasn't available. The first electric lines arrived 15 years ago but electricity supply was rather erratic so these lanterns (called lal-ten in the local dialect) were fairly common for a long time after that (still are common?). These days, electricity supply is more reliable and there are LED bulbs with built in batteries so these lamps are being used less and less.
same memory i miss lalten
As someone who has grown up with reliable electricity since birth, how magical was for you to be able to turn on a light instantly without fumes or smoke?
Cosmo Genesis Yes, these bulbs are created for rural areas where electricity is a problem(thankfully most of the rural areas have been electrified because of the present PM). These bulbs glow about 4 hours using the inbuilt lithium battery pack.
@Vivek Singh that is kind of how I travel. I go to places I have friends, and I try to get a little language and culture first.
I find that being respected and trying to connect to people. Gets you pretty far.
@Sum Arbor Feel free to visit India any time, as soon as this Covid issue gets sorted. You will have a nice time here.
People will try to rip you off by selling you worthless things for a fortune but what's a trip without getting ripped? It's not worse than any other tourist place.
Recently found an old NIER oil hurricane lantern at a re-sale shop. Although it was rusty, it appeared to be intact, except for the glass globe. I am currently restoring it and enjoy the process. Fortunately, Dietz makes a replacement glass globe for this 280 model lantern. Subscribing today. Thanks for your content.
I never thought about 'lantern technology' before and am genuinely intrigued and entertained. New sub for sure.
Brilliant video! I bought my only hurricane lamp for fishing around 1969. (From the army surplus) With the money from my paper round. Never knew how it worked (or even thought about it) . Later replace by far brighter and more expensive Tilley lamps and then an Anchor lamps.
Thanks for the information and history lesson.
I now use 60w (equivalent) led lamp. Still night fishing!
After a year or so of fussing around with a "standard" skinny kerosene lantern for my use out at Scout Summer Camp, I settled on a Dietz; what you call here a cold-blast model. I thought of it as a 'farmer's lantern," because the much-wider base made it harder to knock over. an advantage around a bunch of rowdy boys. IF I have the choice, I'll never get a 'skinny' lantern again.
Some years later, I discovered Aladdin lamps, and yes, we have a couple for around the house. Those mantles Do a Job, and as you say, can even help heat up a cold house. "Live Better Electrically" ?? No way we'll ever have an All-Electric house: There needs to be some options/alternatives.
Dietz? I know several, unrelated Dietz'es. Very humble and very smart. This video is nothing of the sort. That guy, ughhh👎
Have you heard of Dietz & Watson meats? Very very good!
We have two lamps at home for emergency use which look remarkably like the cold blast lamp, but use LEDs. They have built-in batteries, but there’s also a crank which you can use in the event that the batteries run flat.
One of my graduate students worked on a project that involves putting plastic bottles in the ceilings of huts that would provide illumination during the day at no cost. In that project, gravity lamps were used at times when there was no sunlight.
His voice, his tone, his tempo, his pauses, his timing, his composure, his usage of physical gestures... The guy's speech skill is near impeccable.
@Alex someone i know used to too, at least according to their "profile".
He played a lot of skyrim
Keeping a straight face when saying Dietz Nuts
I couldn't agree more with this thread. Self deprecation is another endearing trait not mentioned here.
Overall, Alec demonstrates trade craft that even the so called professionals should be jealous of. I just hope we get to enjoy him a little longer before he gets snapped up.
Oh, and I don't like to objectify people, so consider Alec to be one of my internet friends that I've never met - That very fact can also be considered a sign of mastery of his craft.
@Chris B Everybody needs practice. 🙂
I learned so much from your presentation, thank you! and I loved your outtakes! 😆 I watched those again! 😂
This video is absolutely amazing it is one of the best made videos I think I've ever seen. If the guy reads this that made this video man hats off to you excellent job or maybe I should say phenomenal. Incredibly well done. I don't know what your specialty is. But you should consider a career in education. This was an exceptionally educational video it was incredibly well done.
Well, this is his career. He makes a living on Clip-Share making educational videos
Totally agree Calvin, and I was an elementary and middle school teacher for a couple decades so I should know. LOL!!!
Great video. About your concern of using this as everyday option for light:
I think it will slowly fase out as the price for fuel keeps rising to a point of being unaffordable. At least here in Europe that is. It is not a recent development but over the last decade prices for kerosene have risen and availability declined.
For kerosene heaters this is even more te case.
I understand the health issues but for many there is hardly any alternative.
Very nice video - Thank you.
As in many subjects the real explanation requires some explaning.
Now I finally know the real reason they are called hurricane lamps.
BTW- I was thoroughly impressed by those well preserved lanterns you were using - until you told me they were not antiques but we're new.
Disappointing but nice to know they are still available if we want one.
Thank you for enlightening me!
It's amazing the things we take for granted.
Alec's videos are always enlightening. He's been on a real hot streak recently; all the puns in this video were on fire. No other Clip-Sharer can hold a candle to Technology Connections.
we always used these growing up camping or on my Uncle's farm which only had 12v electricity powered by car batteries and a small generator (their fridges ran on kerosene too as did our camper one) we also had a lamp we pressure pumped with a starter mantle that had a reservoir of mentholated spirits, it got really hot but was very bright
Way back in the day, I sold and serviced kerosene heaters for a time. Pretty much every home in the Appalachian Region had one in the garage. They all operated with a larger version of the tubular wick you showed. I routinely lectured everybody on the dangers of open-flame heating and lighting, just in case their pa didn't teach them right and they had no sense of their own. Kerosene burners tend to collect water in the fuel and wick so they should be stored empty and open, with the old wick discarded and a new, dry wick ready to install. Don't leave them filled with a wick in them unless you are using them daily. And, again, just in case you have no sense; make double-damn sure they are completely out before you fall asleep or you're like to wake up dead.
I’ve been using candles with flat wooden wicks and they are fantastic. They burn beautifully and they make a really satisfying crackling sound.
We lived off the grid in the Sierra Mountains. I loved our kerosene lamps! You’d be surprised by how many people do use them, on a regular basis, here in the states. We still have a variety of lamps including the Dietz which no longer does porch duty. They are great in power outages. There is nothing as peaceful as a kerosene lamp on a dark night. Serenity! -T
Nice - my father had the brass base of the kerosene lamp and we used to play with the tubular wick driving wheel as kids wondering how it used to work (the glass having been broken well before we were born)
