>Hydrogen fuel cell cars that only emit cool, clean water vapor!

Buuuut...isn't water vapor the number one greenhouse gas present in our atmosphere?

I'd sure as fuck get a hydrogen car when it would be available (imo less environmental impact...with electric cars you'd be throwing out environmentally damaging batteries every so often), but wouldn't it be more reasonable to have, Idk, a water holding tank in the trunk? Every so many miles you empty your bucket of clean water, into your garden or wherever?

>> No.3534806

I want a car that takes urine, and provides water. Obviously you'd need to provide more than it gives out, so you'd drink more water than it gives.

>> No.3534818

the amount of water vapor in the atmosphere is constant, if you emit more it will just turn to precipitation

oh wait this is a troll

Solution: Instead of farting that water vapor out, funnel it to a tank, then bust the water into oxygen and hydrogen and burn it again to run the car.

No green house gases, AND you improve gas mileage.

Not trolling. In a green society there has to be an easily transported fuel...moving stacks of batteries in 18-wheelers ain't going to be efficient.

Yeah, yeah, you lose some energy in the transfer, but I'm talking about the day where we have solar panels that are like >80% efficient. You know. The future.

put the solar panel on the car then. I see you got the idea there. But people need to realize that everytime energy is convert from one form to another, a large percentage of said energy is lost. Convert some amount of energy 3 times and you'd be lucky to have a third useful energy left. Electricity is only a fluid carrying energy, it isn't energy by itself.

Gas stations can harvest rain water or use municipal water supplies and then break the water into hydrogen and oxygen. People can then come to the gas stations and acquire the mixture.

Or you can miniaturize the system and put it directly into the car. Modern day car batteries can be used to power the electrolysis that breaks the water molecules into hydrogen and helium, or you can plug your car into your wall outlet and power the electrolysis that way.

There would be no need to transport huge numbers of batteries anywhere.

What about if, instead of moving batteries, we use electricity to push electrons through conducting "wires" into people's homes?

You know hydrogen is the biggest troll tech ever don't you? People who make hydrogen don't make it form water they make it by catalyzing the carbon out of natural gas. So in reality hydrogen just throws away a good portion of energy in natural gas to produce a fuel that is harder to store.

You do know that it is easier to run a car of natural gas than hydrogen right?

Which is why hybrids are fucking retarded as hell.

You burn gasoline, to charge a battery, to run a car.

Compared to, burn gasoline, run car.
