There’s a lot of hydrokinetic power in a moving mass of water. By placing a turbine in that liquid you slow down the velocity of the fluid and convert it into mechanical energy. An electric generator and converter then changes it into electricity. Using this, you have a battery that can be charged 24 hours per day. Idenergie's river turbine can create up to 12kWh per day — which is enough to power a home. It’s an incredibly neat solution, and one that offers to reduce many of the downsides of gas generators — like motor noise, smell of gasoline, and round trips to the gas station. That also includes the amount it’ll cost you, since Idénergie assures users that it will “save you up to 50 percent on your annual expenses by replacing your gas-powered generator.” Idéenergie also says there is no evidence that the turbine is harmful to aquatic life, so no fish will get trapped or injured in the turbine.
