Abstract

A windmill device for converting movement of air into rotation performing useful work has scrolling (2) flexible vanes 1 to channel (4) the air movement, directing them to the tips. The vanes are perforated with elastic (5) apertures 3/7 to extend interaction times and so enhance throughput. Variations of colour and production material enhance operation.

Description

Description:
A device to convert movement of air in to rotation performing useful work.
The device has scrolling(2) flexable(1) vanes to channel(4) the air movements, directing them to the tips(4).
The vanes are also perforated with appertures(3) designed to be elastic(s). The elastic(s) appertures(7) extend interaction times, and so enhance the throughput.
Variations of colour(6) and production material(6) produce an enhancement of operation.
The combination of these effects produce a high pressure output at the tip of the vanes(4) enabling the vanes to rotate.
The vanes should be aerodynamically designed to reduce drag.
