After a decade of work, the first millimeter size turbine engine developed by researchers at MIT should become operational by the end of this summer. The new turbine engine will allow the creation of smaller and more powerful batteries than anything currently in existence. It might also serve as the basis for tiny powerful motors with applications ranging from micro UAVs to children's toys. In the more distant future huge arrays of hydrogen fueled millimeter turbine engines could even be the basis for clean, quiet and cost effective power plants. [continued]

Would love to have one of these running my laptop.
Engine and fuel-tank only 5inches tall is really impressive!
 
Looks interesting. Still need to work on power takeoff. Perhaps some sort of free turbine?
