Is That A Turbine In Your Pocket, Or....

MIT's Gas Turbine Laboratory has announced that they are working on jet turbine engines smaller than a dime. These new micro-turbine engines spin at over 1 million RPM, and can be used instead of fuel cells to replace all kinds of batteries. They could even be used to provide power in third-world countries. (BTW, in case you were confused, the picture is a GE90 engine from the new Boeing 777.)
