We have developed a micro hydraulic power generation connected to tap water, which is convenient to carry in the event of disasters or power outages, and which can use tap water as an energy source. By reusing the tap water used for power generation as flush water for toilets, etc., the environmental impact is reduced. By carrying out a load characteristic test with the developed micro hydraulic power generation, the generated current was 1.2 A with a tap water pressure of 0.3 MPa and a load resistance of 2.5 Ω, and the terminal voltage of the load resistance was 1.5 V. We were able to realize a portable micro hydraulic power generation.
