The cross-section can be made with simple rods in the shape of circles, semicircles, or ellipses! It solves various problems of hydroelectric power generation.
When a stick or similar object is placed in the flow of water or air, vortices are created around it. These vortices generate vibrational forces on the stick. This "fluid-induced vibration" possesses strong energy with destructive power capable of destroying bridges. Professor Hiejima from Okayama University, a researcher in wind-resistant engineering working on vibration suppression, reversed the concept and engaged in research to utilize it for power generation. The result of this research is the flow power generation technology called "Hydro Venus." 【Features】 ■ Inexpensive and durable structure ■ Difficult for debris to get entangled ■ Operable in shallow areas and low flow velocity locations *For more details, please refer to the PDF materials or feel free to contact us.

Company information
We established Hydro-VENUS Co., Ltd. to commercialize the pendulum-type water flow power generation system Hydro-VENUS (Hydrokinetic Vortex Energy Utilization System), which was developed from research at Okayama University. This is the world's first method to generate electricity by vibrating a pendulum using the flow of water in nearby rivers, waterways, tidal currents, and ocean currents. It can also rotate like the conventional propeller rotation methods seen in wind power generation. In the case of the rotating type, it has the unique feature of being able to rotate in both forward and reverse directions, making it suitable for small hydropower generation as it is less likely to get entangled with grass and other debris. Currently, we are developing a flow meter based on the principle that the amount of electricity generated changes according to flow velocity. As it is a self-generating device, it achieves a low-cost flow meter that does not require an external power source. It can generate electricity even in shallow rivers, allowing installation in small to medium-sized rivers that previously lacked water level gauges or flow meters. We are also developing a system that uses AI to predict floods based on data from the installed Hydro-VENUS flow meters.
