As described in prior posts, the bottom of the flow accelerator can attach to the top of a supporting tube in order that the blimp doesn’t have to carry the entire gravity load of the shroud and turbine. This rotor will spin at high rpm, so it is easy to make it a direct drive machine.
Wind Turbine with Flow Accelerating Shroud In other words, a blimp suspends a turbine that looks kind of like the one described in this earlier post: So you just reverse the process, and the reciprocating piston drives the electric generator.Ī blimp suspends a giant flow accelerator with a small high-power turbine in the middle of it. The water turbine is replaced with a reciprocating piston exactly like the kind that the turbines use to raise water pressure in the first place. This variation eliminates the water turbine at the central station where water pressure is converted to electricity.

Reciprocating Electric Generator Variation All you need to do is vary the radius of the off-axis part of the crankshaft. Actually, this would be pretty easy to do if a crankshaft is used to drive the water pump piston. On the other hand, I guess this could be solved by providing each turbine with a variable speed transmission. That way if the wind speed is lower for one turbine than for all the others, the low wind speed turbine will still be able to actuate the hydro-drive.
I guess this idea needs a means of regulating pressure on a per turbine basis. The water pressure at the central collection point is converted to electricity with a water turbine. Instead of electric cables carrying power, water pipes carry power from each turbine to a central collection point. The gearbox and generator are eliminated with this hydro drive.
