TIT & Mitsubishi Prototypes Pollution-free Engine Excluding Fossil Fuel
Tokyo Institute of Technology (TIT) and Mitsubishi Corp. have prototyped a pollution-free engine that does not use fossil fuel. The two entities have collaborated with each other since 2004 for "social value creation by commercialization of new technology and intellectual property." As their first project, they have been working on a new energy system based on a solar pumped laser since 2005. The engine will be included in this system.
The new engine is called "MAGIC (MAGnesium Injection Cycle) engine," and its development has been led by Profs. Yabe, Ikuta and others of TIT with the cooperation of Ono Denki Seisakusho, K.K., a precision manufacturer located in Shinagawa ward, Tokyo. Despite its small dimensions (diameter: approx. 5 cm; height 13.5 cm), the engine can generate a heat output of several tens of kW from which power is obtained. Since the engine generates heat from magnesium and water, it does not require fossil fuel. It is expected to be used as an engine in cogeneration systems, vehicles and vessels.
Magnesium oxide, produced as a by-product, is broken down into magnesium to be repeatedly utilized with the use of solar pumped laser whose development is already well advanced. This indicates that the primary energy is the sunlight and the medium for carrying it is magnesium. Further research is planned with the aim of commercialization in the next three years.
