Wind Power Generated by Exhaust Airflow from Factory

Techno Ryowa Ltd. announced on June 23, 2006, that it has jointly developed, with Wind Power Co. and Naka Co., a system to convert energy from factory exhaust airflow into electricity. Ryowa started selling the "D-Flow Mill" system this fall.

So far, various attempts have been made to recover kinetic energy from factory exhaust and convert it into electricity. These ideas have not been successful, however, because the equipment has been inefficient in power generation, especially where the rate of airflow is slow. Also, if the method or location of installation is suboptimal, the factory exhaust equipment might actually be forced to consume more power.

Unlike the natural wind, however, the rate of air flow from factory exhaust is consistent. This knowledge guided the development of an efficient generator and gear mechanism, and helped determine the optimal position and turbine diameter at the exhaust outlet. The innovations have made it now possible to obtain a highly efficient and stable supply of electricity.

Coupled with a battery storage system, the electricity produced can be used as an independent power source for various purposes, such as area lighting, indicator lamps, signage, and security sensors. Although the systems produces only a small amount of power, the developers hope that they might be useful for raising employee¡Çs and general awareness about the importance of efforts to reduce carbon dioxide emissions and to conserve energy by reducing oil consumption.
