The development of two new designs for low-power wind systems is considered: one with a horizontal rotor axis and the other with a vertical rotor axis. The development of environmentally safe power sources is of enormous importance at present. It is clear that there is no real future for the combustion of mineral fuel as an energy source, in view of the exhaustion of fuel reserves and global environmental deterioration. Wind power is very promising. Wind energy, which has been in use for hundreds of years, is renewable and has virtually no environmental impact.
