There is a second law which is unrepealable.

The extraction of hydrogen from water by electrolysis is an old saw. I did it in high school and Univ. The trick is to make it more efficient. Advanced polymer cell barriers help. So you get hydrogen gas.. so what? You had to make heat to make the electro-juice to make the H2 and you lost 50% making the e-juice thermally. So you use the hydrogen for what? More heat and you lose 70% again.. unless you use it in a fuel cell so you only lose 30%, so you can claim about 30% total efficiency.

So why not make alcohol as it is cheap to make and then fuel-cell that, as it has plenty of hydrogen. The goal is efficiency. Alcohol to electricity no matter if the Pt in your engine costs 8,000 would be so efficient that at 4.00 a gallon the engine at 70% efficiency would pay for itself in
about 40,000 miles or 2 to 3 years. In six years before trade-in you are another 8,000 ahead, so the engine makes you 1350 dollars per year or the maintenance. You save a lot more because the electric motor is relatively maintenance free and the car could be made simpler with regenerative braking and direct drive on the wheels to save friction.
