Nanotech Pinball and Miniature Engines

glenmark writes "Researchers at the Solid State Electronics Laboratory at Chalmers University of Technology in Sweden have developed the world's smallest pinball game. The video is fascinating. The flippers are electrostatically-actuated monocrystalline silicon cantilevers. I hope Pat Lawlor and Steve Ritchie see this. I have a feeling they would get a kick out of it." And in another nanotech story, psmears writes "Three hundred times more powerful than ordinary batteries, but much lighter and smaller? Researchers at the University of Birmingham have developed a micro-engine that will allow people to charge mobile phones using lighter fluid.
