Abstract

A wind power generator is enclosed at the center of a duct. The duct comprises an upper and lower duct panels having solar panel. The distance between the upper and lower duct panels is the smallest at the center where the wind power generator is mounted. The distance gradually increases as the upper and lower duct panels extend further away from the wind power generator. Thus, the duct collects wind blowing toward the wind power generator and increases the speed of the collected wind, thereby achieving an increase in the quantity of power generated in the wind power generator.

Claims

1. A charging station comprising:

a duct formed with an upper duct panel and a lower duct panel, said upper and lower duct panels including at least a solar panel;

a wind power generator provided between said upper and lower duct panels that generates power by using wind force; and

a battery that stores power generated at said wind power generator and said solar panel, wherein;

said duct is formed so as to collect wind blowing toward said wind power generator and increases the speed of the collected wind.

2. A charging station according to claim 1, wherein:

said upper duct panel and lower duct panel are rectangular respectively as viewed from above,

said duct includes a pair of inlet/outlet portions, and

a width of said each inlet/outlet portion gradually degreases toward said wind power generator.

3. A charging station according to claim 2, wherein:

said inlet/outlet portions have an inner surface curved according to hydrodynamics.

4. A charging station according to claim 2, wherein:

said wind power generator is provided between said pair of inlet/outlet portions.

5. A charging station according to claim 2, wherein:

said upper duct panel includes a panel transmitting a visible light,

said solar panel of said lower duct panel is arranged so as to receive a sunlight through said panel transmitting a visible light.

6. A charging station according to claim 2, wherein:

said upper and lower duct panels are each constituted of the first-third panel elements, and

said first and third panel elements are inclined to form said inlet/outlet portion respectively.

7. A charging station according to claim 2, wherein:

said upper and lower duct panels are each constituted of the first-third panel elements,

said first and third panel elements are inclined to form said inlet/outlet portion respectively, and

said second panel elements of said upper and lower duct panels are parallel to each other to form a space between which said wind power generator is enclosed.

8. A charging station according to claim 1, wherein:

said upper and lower duct panels are circular respectively as viewed from above,

and the distance between the upper and lower duct panels becomes gradually reduced from the periphery of said upper and lower duct panels toward the center of said duct.

9. A charging station according to claim 8, wherein:

said wind power generator is provided at the center of said duct.

10. A charging station according to claim 1, wherein:

said wind power generator is a Savonius wind power generator.

11. A charging station according to claim 10, wherein:

an opening is formed at at least one blade of said Savonius wind power generator to reduce reverse torque of said Savonius wind power generator.

12. A charging station according to claim 8, wherein:

said wind power generator is a Savonius wind power generator.

13. A charging station according to claim 1, wherein:

said wind power generator is a blade-type wind power generator.

14. A charging station according to claim 8, wherein:

said wind power generator is a blade-type wind power generator.
