<p>PROBLEM TO BE SOLVED: To reduce energy loss of an omnidirectional windmill. SOLUTION: In an omnidirectional windmill, semi-spherical shell-like wind receivers 1 to 4 rotating around a rotary shaft 10 are attached to the rotary shaft 10 through an attaching fitting 11. The semi-spherical wind receivers 1 to 4 are rotated around the rotary shaft 10 while receiving wind at their recessions 30. Slits 20 are formed on the wind receivers 1 to 4. The slit 20 is formed between a pair of curved portions 33 bending smoothly from a projection side 31 of the wind receiver and projecting toward a recession side 32.</p> |
