Mechanical energy generating method for use in e.g. nuclear explosive area, involves driving heat engine turbine using heated working medium, so that turbine generates mechanical energy, and transferring energy to device to be driven

摘要

The method involves aligning a beam i.e. laser beam (22), of an electromagnetic radiation on a light absorber (14) of a heat engine (10), so that the absorber heats a working medium (16) e.g. air, of the engine. A turbine (12) of the engine is driven using the heated working medium, so that the turbine generates mechanical energy. The mechanical energy is transferred from the heat engine to a device to be driven. The laser beam is produced by a carbon dioxide-laser beam or a solid state laser i.e. neodymium, yttrium-aluminum-garnet (ND:YAG) laser. The absorber consists of ceramic. An independent claim is also included for a heat engine with a turbine and a laser.
