the vertical windmill turbine generator is a combination of three distinct previously defined inventions by the same inventor and one new invention . it is designed to take advantage of the increased , wind speed caused by the up welling or downward sliding of winds found at walls , fences , or roofs and similar obstructions . this windmill generator has infinitely adjustable vanes , which allow the windmill to govern its speed or respond easily to very low - speed winds . the design also allows inertia to more readily be taken advantage of . with the included flying - magnet - dynamo , as the generator , the static inertia of the windmill generator is greatly minimized . the electrical output is gathered with low esr capacitors , then regulated by a switching regulator . vibration and speed censors detect over - speed and agitated wind situations , allowing the device to protect itself by closing some or all vanes instantly . the rotating components communicate with stationery components by radio .
