    Fun fact! It is thermodynamically impossible to make a vehicle that derives its energy from water. You cannot get more energy out of a water molecule than you put into it.

    Edit: forgot about fusion. It is thermodynamically impossible to derive energy from the chemical bonds in water without putting more energy in than you get out. None of these water powered cars are using fusion generators. They’re all about splitting the oxygen from the hydrogen and then burning the hydrogen with the oxygen, and there simply isn’t a way to do that without wasting a ton of energy

      They are going to kill this man, because his invention will void a trillion dollar industry, and make it seem like an accident by bringing the whole plane down.

      Water has too low of potential energy to use as fuel in normal circumstances. The people who say this stuff usually say its patents or a secret method kept secret by car companies and are conspiracy brained.

      Realistically probably this originally started as somebody being told about hydrogen fuel cells and people telephoned it into a conspiracy theory.

        Realistically probably this originally started as somebody being told about hydrogen fuel cells and people telephoned it into a conspiracy theory.

        Realistically it probably started as a scam as, like the “this one weird trick! Doctors hate her!” thing. The premise is simple: learn how to modify your car to run on water instead of petrol (which sounds wonderful - so cheap! So convenient! Imagine if you could just fill up a bucket and dump it into your fuel tank and it’d work!). It sounds intuitively plausible - water is a liquid, petrol is a liquid, car is a machine that turns liquid into vroom - and frankly nobody in the general public knows why water-powered engines violate thermodynamics, only that they do (assuming they do).

        And you really need to understand that these scams target the dumbest motherfuckers on the planet. The fact that it filters out anyone who applies critical thinking and education is a feature, not a bug.

          I don’t disagree with the idea silliness is a feature not a bug, however most conspiracies that gain a lot of traction have a hook they use to try to get people in the door. Often that starts as something true-ish even if it is misdirected 180 degrees within the group of conspiracists (see Qanon’s pedophile cabals).

    Me too. It uses a battery to heat water into pressurized steam.

    It’s not very effective.
