Abstract: Electricity is produced by harvesting energy from flowing water, which does not harm the environment and which does not consume natural resources. A paddle wheel is stationarily positioned to penetrate the surface of a body of water. Preferably, a plurality of paddle wheels are deployed on a single floating platform to optimize the transfer of the energy contained in the flow of water passing the floating platform. Each paddle wheel is geared to rapidly rotate a generator axle of an electricity generator of the type conventionally deployed for wind turbines on “wind farms”. Preferably, each paddle wheel powers a plurality of electricity generators. Structure is provided to compensate for variations in flow rates in the body of water to intensify a flow of the water and to vary a depth of penetration of the paddle wheel into the water.
