Events【Announcement】Elis' WaterWeco® Wins Invention Association's "Chairman's Award"
2024/11/07
Tsubame Holdings (Okayama City) announced on October 29 that the "Economical Small Hydroelectric Power Generation Device with Automatic Load-Following," co-developed by Jun Kuwahara, President of Elis (Okayama City), and Dr. Soichi Sasaki, Assistant Professor at the Graduate School of Engineering, Nagasaki University, received the Japan Institute of Invention and Innovation's "Chairman's Award" for this year. The technology is incorporated into Elis' unique small hydropower system, WaterWeco®, which the company manufactures and sells.
WaterWeco® utilizes high-velocity surface water, adjusting the angle at which water hits the turbine to ensure efficient generation without reducing flow velocity. The system allows for efficient power generation even if water volume varies. It can be installed in irrigation canals and rivers with large fluctuations in water volume, thanks to its ability to automatically adjust to load changes. Additionally, by utilizing only the high-velocity surface water, it reduces the burden of debris management and contributes to the preservation of ecosystems. WaterWeco® is patented in over 50 countries worldwide, including the U.S. and Europe, and is also listed on the Sustainable Technology Transfer Platform (STePP) of the United Nations Industrial Development Organization (UNIDO) Tokyo Office.
