Over the decades there have been lots of companies claiming they will bring out cars that run on water but whats the problem? Why havent they done it yet?
It seems to me that the only ones to've claimed to make an engine run off water have been fraudsters. Do you think such a thing could be made to work? The schemes I've seen so far have been flawed.
Well assuming we're thinking of the same thing, you split water up into hydrogen and oxygen and then recombine it in the car, electrochemically like a battery. Firstly you dont do anything for the environment as you have to generate electricity to split the water in the first place and this is all probability generated by fossil fuels, secondly its harder than building an internal combustion engine. So why bother?
Right, converting electrical energy to chemical energy and back into electrical energy doesn't do anything to circumvent conservation of energy, but I was just curious if the threadstarter might have something else in mind (though I'm pretty convinced water couldn't be used as a fuel).
Ok so what you are saying is it would just be too inefficient because a better result would be had from hydrogen - so apart from electric cars why arent these alternatives being put into practice - theyve had 4 decades to think of something better than petrol driven engines
