Abstract

A linear wind powered electric generator (LWPEG), which is particularly adapted for installation at geographical sites subject to lower wind intensities. More specifically, there are provided design concepts for an LWPEG, possessing reasonable economic parameters for utilization at the lower-intensity wind sites. Moreover, the linear wind powered electric generator is based on a track based wind power generator, incorporating aerodynamic designs, which are adapted to reduce mechanical complexities presently encountered in this technology, while being cost-effective both in construction and in connection with the operation thereof.
