Have a small stream on your property and want to use it to generate electricity? Check out this hydropower generator designed to be used in rivers and small waterways.
"This machine uses a special housing called a diffuser. In this way, it utilizes special technology to increase the rate of water flow through the vanes that extract energy. That energy turns the vanes, and gets converted to electricity by a generator. Then a controller and battery produce 100 V AC electricity at 50/60 Hz that can be used in the home."
"With water flowing at 2.0 m/s, this system can produce 250 Wh. Taking control losses into account, five of these can deliver about 1 kW, so this system can be used as an emergency power supply."
