It’s becoming increasingly obvious that wind-powered generation is a practical failure; failing miserably to deliver electricity when needed. This invention makes use of the existing wind-generator structure and infrastructure connection to provide electricity generation when the wind doesn’t.
The invention is to install one or more pulse-jet engine near the tip of each wing in order to rotate the machine and generate electricity when there is no wind, but a demand for electricity. Pulse jet engines are very simple machines with few moving parts and run on a variety of fuels.
As wind strength drops, the normal wing action is feathered and fuel supply to the engines opened along with an ignition source. The flow of air through the engine is sufficient to start the pulse-jet engine.
Many wind generators already have access to a source of combustible fuel; usually gas, which is used to keep the mechanical equipment (generator, hydraulic pumps, gearboxes and control gear) inside the nacelle from freezing. There is also the ability to drive the rotor using grid power; necessary to prevent bearings and shafts from being damaged when there is no wind to turn the machine.
Some may argue that this is a hare-brained, ill-conceived invention. But what of the wind generators by themselves?
