Hydrokinetic power is made by generating electricity from moving water, without the need for a dam. In this case, a turbine will be suspended from a barge on the Mississippi River. The turbine will hang about three feet below the river's surface and the current will turn the blades, which will power a generator and create about 100-200 kilowatts of electricity.
Because this type of renewable energy uses the river's natural current rather than relying on the construction of a dam (as with hydropower), some are calling hydrokinetic energy "underwater wind power."
The company building the station is Texas-based Hydro Green Energy. A spokesperson for the company said small-scale projects like the Hastings one can work in remote or rural communities where power demand isn't high but where there is a challenge in delivering power. Hydro Green Energy is also studying whether the turbine will harm the Mississippi's fish.
