more power not to mention better mileage too, I believe, for the price vs. diesel.

I saw GreenBenz selling a water injection & biodiesel ready 300sd on Ebay not too long ago. It was so nice. The car was in basically perfect condition, not to mention it got great mileage with the water setup. I truly believe in these systems and am all for "greener" fuels. This world is going to waste faster than anyone can probably even know...

If I remember, isn't hydrogen injection kind of comparable to a nitrous setup on a gas engine? My mind is a little fuzzy these days.
