Title Air-Steam Hybrid Engine: An Alternative to Internal Combustion
Publication Date Mar 2010
Media Count 49p
Personal Author M. J. Brookman R. Knight
Abstract In this Small Business Innovation Research (SBIR) Phase 1 project, an energy-efficient air-steam propulsion system has been developed and patented, and key performance attributes have been demonstrated to be superior to those of internal combustion engines. A mixed air-steam propellant system can provide immediate power without a boiler, and that power can be varied simply by modifying the ratio of water and air in the propellant mix. Next steps for this innovation include more detailed performance verification and an analysis of scaling this promising technology to propel buses and trains for mass transit use. Successful validation would lead to a vehicle retrofit of a smaller, lighter, more fuel efficient engine in a standard mid-size or full-size vehicle. That engine could operate on a variety of fuels other than refined petroleum. These goals are consistent with the DOT SBIR subtopic narrative, Economical and durable technologies and devices for improving safety for riders and transit agency employees, reducing noise and energy consumption, or improving the rider experience. The innovations must be adaptable to existing bus and rail transit vehicles and systems.
