Abstract

The Drum Pouch Wind Turbine consists of drum shaped cage structures wrapped with fabric pouches all around the perimeter which catch the wind on one side. The pouches may be stretched between two rings, one ring on each end. The system may consist of at least two drum impellers, one drum rotating clockwise and the other counter clockwise, doubling the relative rotational velocity between each pair of drums and having double the torque (because of the counter rotation), thereby increasing power output with the same wind speed. In essence, the system is composed of two counter rotating impellers and one generator, one portion of the generator on each drum.
