good news for longer lasting & better battery power - without the battery. researchers at MIT have placed a tiny gas-turbine engine inside a silicon chip about the size of a quarter. the tiny engines could ‘power a person’ and all their electronic devices (laptops, cell phones, etc.) up to 10X longer than a battery of the same weight and size. the engine components (compressor, a combustion chamber, etc.) where built by MIT researchers using etched silicon wafers piled up and bonded together. When the wafers are assembled, the surfaces and the spaces in between produce the needed engine features and functions. To make this process more less costly, 60 to 100 components are made on a large silicon wafer which is then cut apart into single units. found via physorg and boingboing.
