- bawolff 6y agoHow would that work? That sounds like a perpetual motion machine.
- thysultan 6y agoLike how a gun works, essentially a battery for the initial motion, using the subsequent motion storing some for the next initial motion.
- bawolff 6y agoGuns work by having chemical explosives in them. Which is also how gasoline powered cars work. They definitely do not work by using a depleted battery to charge a second battery to create energy out of nothing.
- thysultan 6y agogasoline cars also use a battery to initiate the engine.
- bawolff 6y agoYes. However they don't use it to both power the car and charge the battery. Kickstarting the engine with a battery is very different from only having a battery and also using that battery to charge itself and the car at the same time. The original poster was proposing a closed system where you would turn water into hydrogen (a very energy intensive process) and then turn it back into water (an energy releasing process) inside the car to provide all the energy. This is not how physics works. You cannot use your energy source to create more of your energy source without an external energy source. It just doesn't work that way.
- sputr 6y agoNo, it's not :) Where would you get the energy to split the water? Why not just use that energy directly :). The idea is to use the water as an energy carrier. You split the water into H2, than use that to power a car producing water as the only output.
- rzzzt 6y agoIf cars produce water as exhaust, will there be constant rain showers on congested roads?
- maxerickson 6y agoThey already produce plenty of water in the exhaust.
- _ph_ 6y agoRight, I did a simple calculation, for the same distance driven, both gasonine and fuel cell cars produce pretty much the same amount of water, about 100ml/km. Only difference is, with gasoline that water is mostly vapour, so it doesn't get on the road so much, fuel cell cars have small tanks not to wet the road constantly.
- ianai 6y agoWatch a YouTube of a hydrogen car review. They produce maybe a cup of water for a consider amount of driving. It’d evaporate relatively quickly.
