Energy conversion systems utilizing nanometer scale assemblies are provided that convert the kinetic energy (equivalently, the thermal energy) of working substance molecules into another form of energy that can be used to perform useful work at a macroscopic level. These systems may be used to, for example,...http://www.google.com.hk/patents/US7262515?utm_source=gb-gplus-share專利 US7262515 - Energy conversion systems using nanometer scale assemblies and methods for using same
