Refuel my laptop please, or the smallest combustion engine

Anonymous Reader writes: “ZZZ has a short report about the smallest combustion engine in the world developed in University of California. It is so small that the only way to make it is etching it on a silicon, like computer chips. The funniest thing is that the scientists are going to use a throng of these engines to power laptops, PDAs, cell phones and other portable electronic devices. The whole world it trying to stop the pollution and these guys develop a combustion engine, isn’t it ironic?”
