Laser Refrigerator

"MEMS (micro electro-mechanical systems) market was supposed to make the breakthrough in miniaturization. In practice, they are limited in power and so are reduced to very simple optical uses. With this engine, a new world of applications will be availablein the defense, space, communication and medical industries.We propose an engine 1,000X faster; smaller; and more powerful than electrically powered ones. Our engine can power miniature mechanical devices, opening up a world of applications now unavailable due to technical constraints of current solutions.For instance, two possible applications are micro refrigerators and mechanical actuators 1,000X smaller than electromechanical ones. A specific use for the technology we intend on developing is to power a closed cycle miniature cryocoolers, forcedconvection cooling loops for high power electronics and lasers and multiple use pyrotechnic devices. Commercial opportunities include powerful miniature medical instrumentation and "cash cow" applications such as true all-optical switches and true laser ink jet printers with five times the speed of current inkjet, for the same cost."
