The efficiency of a hydro-electric generator is improved by providing open-ended hollow tubes having influx ends proximate the axis and efflux ends proximate the periphery of a fan-bladed turbine. The jets of water developed by rotation of the fan-bladed turbine are directed against turbine vanes at the periphery of the fan blades. The device is particularly suitable for mounting in a water current such as in an ocean current or river.

A hydro-electric generator of improved efficiency, comprising a frame, first stage turbine means including fan blades for conversion of the kinetic energy of a water current into rotational energy, said first stage turbine means having an axle and a periphery and being mounted for rotation on said frame; second stage turbine means mounted on said first stage turbine means including hollow tubing means, each hollow tubing means having an influx end and an efflux end and being mounted essentially radially on said first stage turbine means with said influx end proximate said axle and said efflux end proximate said periphery for producing a jet of water by centrifugal action, and including turbine vanes positioned at each efflux end and oriented for receiving said jet of water and for projecting said jet in a direction such as to produce rotation of said second stage turbine means; and electro-mechanical means for converting the rotational energy of said first and second stage turbine means into electrical energy.
