A) That’s called a hydrogen car, and they exist already.
B) Never, the output is water. Then you just use enegy to split the water back into hydrogen and oxygen before burning it back into water. Just add energy from your preferred renewable source.
This guy…. ermm…. waters?
It sounds like you know how these things work. Will you build one for me?
Eh, just buy one.
Nah, that’s expensive, I’ll just top off my gas tank with water until it adjusts to its new fuel type instead.
Can you please name a make & model? Otherwise afaik Big Oil works really hard to make sure hydrogen powered vehicles never get into the hands of common folk.
Hyundai Nexo
Honda CR-V fuel cell
Toyota Mirai
They’re mostly only sold in Japan and California, as that’s where there’s actually hydrogen fueling infrastructure.
There are other models, they exist, these cars are real.
Well hallelujah I live in California & I want one. Now just need some 🤑
That’s the real issue, the main reason I didn’t have an electric car is that I basically never buy new cars, and the used car market is really still growing for electric vehicles.
The conversion of water to hydrogen using electricity has about 20% efficiency. There is no advantage over electric vehicles ever since batteries have become compact enough to make battery-powered electric vehicles feasible.
There is no advantage over electric vehicles
What about batteries’ explosive potential & a lifespan shorter than the metal cage it propels?
Hydrogen vehicles would be superior to that.
What about batteries’ explosive potential
The Hindenburg was battery powered, oh, the humanity.
Guess what element on the periodic table causes batteries to explode? hint: not mentadent.
Oh yeah. Thanks for reminding me.
Batteries don’t really explode, they combust. The metal cage usually outlives its ICE engine as well.
Hydrogen fuel cell vehicles either need extreme insulation to keep the fuel cool, otherwise it has to vent some fuel or risk exloding, or extremely strong pressure vessels in the car to maintain the hydrogen in a liquid form. A metal cylinder constantly expanding and contracting while simutaneously seeing extreme temperature changes is going to wear out much faster than the frame of the vehicle.
What about batteries’ explosive potential
Compared to a literal TANK OF HYDROGEN. Hmmmm…
a lifespan shorter than the metal cage it propels?
Yeah, there aren’t any cars in the junkyard that were scrapped because they threw threw a rod or chewed up their transmission…
Wow. Just, wow.
There are some advantages, batteries require more pollution to be created and have a larger environmental impact if not dealt with properly. A hydrogen car has the potential to be 100% clean. That being said I don’t think it’s that big of an advantage considering some of the difficulties involved in it.
Oh sweet. Apparently the nearest hydrogen fueling station near me is 2.8 miles away 😃 I remember around 2004 I was reading about & very much looking forward to hydrogen cars but they didn’t exist yet, and I hadn’t heard a thing about them since then until now. Why are these not publicized & more popular??? Or have I been living under a rock 😭
Why are these not publicized & more popular???
Fueling infrastructure is still very scarce and EVs have gotten more popular since then
They really became a lot less of a desirable option as EVs started to get better. EVs have a couple of downsides (weight, charge time) but pretty much everything else about EVs is easier. Hydrogen is a pain in the ass to store in a compressed state, the engines are for more complex than an electric motor, EV charging is easy and obviously far more available at this point, etc.
and it’s only $14-$32 a kg!
Annual petrol usage by cars: ~1.5 x 10^12 litres.
Amount of water on Earth’s surface: 1.386 x 10^21 litres.
Percentage of water used annually: 0.0000001%
Number of years to deplete all water on earth’s surface: 1 x 10^9 years, aka 1 billion years.
Minus a few million if we’re driving yo momma around.
By far most of that water is not fresh water though
The conversion of saline into fresh water via the water cycle will be sufficient to keep the cars running, though maybe not humans. The proof is obvious and left as an exercise to the reader.
=)
We’d never run out because that car is supposedly a perpetual motion machine that converts water to hydrogen and oxygen, then burns it back into water.
