Hydro Green Energy, which wants to plumb America's waterways for electricity, has received $2.6 million in funding.
The company wants to create somewhat small, modular turbines and then set them down in arrays in waterways. Each turbine would be capable of harvesting 250 kilowatts of power. The size of the array would then depend on the size and power of the waterway.
It hopes to plant these arrays in Minnesota, Louisiana, Mississippi, and other states.
