I remember an article in Popular Science magazine in the 60's written by their car guy, Smokey Yunik (sp?). He claimed back then that the future was Hydrogen cars. I've heard of the hydride conversion technique for almost that long.

If I remember the old article from back then, they found they could run any gasoline engine on hydrogen, and get about 75% or so of the power as gas. The neat thing is that hydrogen produces so little friction that they had to put abrasives into the oil to get it to break in. Engines run purely on hydrogen might last a long time. Except this web site mentions the corrosiveness of high temp steam is something I hadn't heard of before. Perhaps that's the gotcha in this.

Why some people say it takes "20 years" to convert to hydrogen I'll never figure.

It wouldn't take me 20 years to use hydrogen in my car, if I had the money to do it, and had the home producing generator.
One problem is ? if I drive a long distance , I hope the final destination will have a hydrogen producer there.
Unless, once I run out of hydrogen, I can flip a switch in my car, and be running on gasoline until I can get some more hydrogen.
But ? having 2 tanks in my car ( gasoline and hydrogen ) be a problem of finding a place to install the hydrogen tank ? The big problem ( if it is feasible ) for most people now is the start up cost for having this system.
