Do you think the future of green engines is just flex-fuels, hybrids or fuel cells? Can you imagine a future with engines that have ethanol turbo-like injection or use steam super-heated by hydrogen? These engines are in the lab today. The video above is a look at a hybrid ethanol injection engine developed at MIT and it could improve mileage by 30 percent.
Below the fold is video of a water-powered car. "Oh, no, not another water car," you say? No, this one is different because it uses a H.A.W or "hydrogen air water" mix and involves super-heating steam to move a piston, says this web page. According to one translation of the video, the Japanese government is looking into it.
