Electricity sales and community contribution business

Issues before installation

It was unclear whether the research and development of efficient equipment for installation in rapid-flow waterway would yield results.
However,the shape of the blades(design) based on analysis of hundreds of patterns of blades in model tests and a mechanism(patented) that can maintain stable output even with fluctuating flow rates were developed, and a dusting device was also made unnecessary, which significantly reduced maintenance costs.
