Greene Turbine has a patent pending game changing electric generator for river and ocean currents. This system is cheaper than coal.
Greene Turbine LLC is a start up getting ready to harness hydrokinetic energy (e.g., flowing river) to produce utility-scale base-load electricity 24/7 with zero carbon footprint and zero fuel cost. The cost of electricity produced by this environmentally benign system is competitive with coal-produced electricity. Although TVA has an interest in electricity from this source, the potential customer base is anyone who uses or sells electricity.
