You always have to give to get...........Auto manufacturers have had the 411 on this stuff for a long time, but until Feds make it manditory like they did for seat belts, catalytic converters etc,etc, you will only see and hear about it in bits and pieces.....easy for the public to forget that way. You wont see a hydrogen powered vehicle for retail sale until at least 2020. They have the technology.........but remember the daily price of crude
oil is more important than anything. Efficiency is a no-no, it usually drops the price of crude and that means NO money
It happend already with the EV GM built everyone loved them, but they were too good and that was bad........All you have to do no is go buy a Tornado, use magnets on your fuel line, get some special friction reducing additive, and all the other gauranteed things you see on TV and you should get about a 50% improvment in mileage and power
