I volunteer to gather eyewitness info on water into hydrogen. Answered
I'm a beginning engineering student and my dad is also an engineer. He is pretty skeptical and he recently told me of someone he knows who is using electrolysis to get better gas mileage in a Toyota pickup. I'm not sure, but it seems he is using secondary voltage to power the split and then burning it. He claims 60 mpg. If you guys would like to give me a series of questions/tests, I would love to go to my hometown and ask/perform them, then report back. Any takers?
