Abstract

[Problem] To provide a motive power supply system that can supply stable motive power and an electric power generation system that can generate stable electricity at low cost, without being affected by hours of sunlight, weather, etc. [Solution] A motive power supply system 10 comprises: a drag-type wind turbine 20 having a plurality of blade members; a flow channel forming part 30 that forms a flow channel by which a flow of air that exited the drag-type wind turbine 20 is used again as a motive power source for the drag-type wind turbine 20; a transmission part 40 that decreases or increases the speed of rotation of the drag-type wind turbine 20 to output the same to the outside; and a drive device 50 for rotating the drag-type wind turbine 20 that is standing still.

IPC Classes  ?

• F03D 3/04 - Wind motors with rotation axis substantially perpendicular to the air flow entering the rotor having stationary wind-guiding means, e.g. with shrouds or channels
• F03D 9/39 - Wind motors specially adapted for installation in particular locations on stationary objects or on stationary man-made structures within towers, e.g. using chimney effects with means for enhancing the air flow within the tower, e.g. by heating by circulation or vortex formation
