Drinking Nasty Swamp Water (to save the world)

  • Published on Feb 14, 2019 veröffentlicht
  • While I'm normally a physics guy, got to give the chemists out there props on this one. Also props to Bill and Melinda Gates for partnering with me on this video.

    Summary: I used some powder that has a flocculant in it to make swampy water drinkable. This can be used in situations where people don't have access to drinking water. Then I met up with Bill Gates and we talked about why we should help poor countries.

    The last few minutes with Bill and the dialogue at the end was so amazing. The message is so beautiful and so well supported it really makes (so i hope) people genuinely want to make a change. The reasons he gave were very factual and amazing to think that way because I'm sure a ton of people that watched this never thought of those things. Great great job Mark and MERRY CHRISTMAS TO EVERYONE!!!

    It's extremely important for ALL of humanity that we think hard about what the next pandemic will be and work hard to prevent it because if it happens and we're not ready, we'll be dead wrong in SERIOUS trouble. Anyway, what a wonderful, cool and fascinating scientific way to make clean, drinkable water.

    There also is polyglutamic acid, which works the same way. It's found in a particular food made from the fermentation of soybeans (i.e. natto). I think it's decent that more than one person came up with solving a problem about dirty water.

    Hey Mark love this idea. We so need more solutions like this. Have you seen or heard about solar buddies.? They are helping kids in 3rd world countries study at home when they don't have power or other lighting options. They are also using then to replace kerosene lighting to help reduce the related health issues. These two solutions go hand in hand and would greatly improve the lives of many people around the world. Cheers and my kids love your channel (so do my wife and I).

    "When the next pandemic comes..."
    Basically it is impossible to be wrong with that statement, because there will always be a next pandemic (after the last pandemic is before the next one). In that case the statement was quite close to the actual call.

    We need a Bill Gates in the computer/humanitarian area, a Mark Rober as an engineer/influencer, etc. Pretty much everyone is intelligent in some way, the world just needs to work together to have everyone shine their brightest.

    Combining this with the much newer Zipline drones could help a lot more people get access to clean drinking water.

    That’s so awesome I love seeing The each individual dirt particles from the water go to the bottom and the water is completely clear. Edit: what Bill Gates!

    So I had to do a science lab for class where I had to treat water using things you would find in the environment. Just used this video as a reference to a different way I have seen it done before. Thanks Mark!

    I’d probably drink it if I don’t know where it came from exactly. The thought that it came from sewers is enough to discourage me. But, I guess if I get too desperate for water, maybe my mind could be persuaded.

    I live in a place that boasts the -best- quality of water in the world and I love it and I always wish I could help the entire world have water this clean. To have a 32 ounce cup at my desk that's always topped off to the top with clean drinkable water that is of amazing quality feels like such a blessing.
