Description:

·         A non-conventional wind power-generation system that uses a spring-

loaded flapping mechanism situated around the outside to the blade of the

wind mill , possibly in resonance with the wind to generate power.  As the

wind creates updrafts against the side of the windmill , the vortices shed by

the cylinder at the top of the flap-arm causes that move the arm in rotary

motion .  As the arm moves, it passes a gear set on a rod through a coil,

thereby generating electricity.  The advantage of the flapping system over

conventional wind turbine systems is that the "cogging" effect that plagues

turbines under low winds peed conditions does not exist in this design.  It is

also far safer than blades, and we predict it will be more cost effective as

well. , but it is our belief that with a properly selected magnet and coil, it will

be a commercially viable wind-powered generator.

THE FLAPPER - The two supporting bars are allowed to rotate freely

through 360 degrees, but hang downdue to gravity and pass right

through the central column. The flat plates are fixed to the bars at 90

degrees to each other, They move from vertical to horizontal in the wind 

flow and at the same timetransfer the energy to the central column to make

it rotate. This therefore is the basic concept.Experimentation would

demonstrate this unique concept. Variations of the design could be

stacked, supported in a frame, clockwise or anticlockwise rotation, flaps flip

up with flotation in air , huge blades -simple build, MW capacity. Four, six or

more flaps possible. At least four flaps are required so the device

turns. The blades go round so fast in air that they disappear. The

movement can be slowed using a strobe light or in air.
