More than ever before, automakers have been putting some serious creative thought into improving the efficiency of automobiles. Some are improving the combustion reaction with ideas like hydrogen injection, and others are attempting to recapture energy that is otherwise wasted, such as the idea of regenerative braking. BMW is working on a variation of the latter, but rather than trying to utilize "waste" momentum, they are aiming to put a conventional gasoline engine's excess heat to good use. And they're using some good-old-fashioned technology to accomplish it: steam power.
