VARIABLE COMPRESSION RATIO FREE PISTON INTERNAL COMBUSTION ELECTRICAL GENERATOR Sandia National Laboratories has designed a two stroke engine to produce electricity not power, run at essentially constant speed and power, and because of its design characteristics, maximize thermal efficiency while minimizing emissions at the operating point. The engine will shut off when not needed and run at essentially constant speed and power when on. This engine does not have either a crankshaft or a valve train and has only one moving part. It can operate on any fuel by adjusting the compression ratio for a given fuel. The engine is light weight and no massive rigid structure is required to support the engine. This technology has potential applications in hybrid vehicles in the automobile industry and stationary power generating applications (e.g.) electrical generators. This is not a solicitation. Parties interested in licensing this technology are invited to submit a letter of interest providing information about the company, area of potential application for the technology and a point of contact. Letters should be sent to: Joanne Trujillo, Sandia National Laboratories, P.O. Box 5800, Albuquerque, NM 87185-1380. (FAX) 505-271-4202.
