Une percée dans le domaine de l’énergie portable: des piles au silicones qui sont en fait de miniatures moteurs à combustion!
So far, it all seems to run. Inside the tiny combustion chamber, fuel and air quickly mix and burn at the melting point of steel. Turbine blades, made of high-strength microfabricated materials, spin at 20,000 revolutions per second, 100 times faster than those in jet engines. A mini-generator produces 10 watts of power and a small compressor raises the pressure of air in preparation for combustion.
Pourra être pratique pour des applications militaires, mais gageons que les applications commerciales suivront assez vite pour les gps, les lampes de poche et les baladeurs!
