The invention comprises a float system having a float connected to a pump line and a reservoir tank. As the float rises and falls with the passing swells, it forces water through the pump line into a reservoir tank. An outflow line connects the reservoir line to a generator system, preferably located on shore, where the flowing water is used to drive a turbine and generate electricity. Preferably, there are a plurality of reservoir tanks, each with its own float and pump line, delivering water to the generator system. The flow of water through the pump line is kept steady by providing each reservoir tank with a pressurized air cushion which provides for constant outflow of water from each tank despite variances in the inflow.
