Document Type and Number:
Japanese Patent JPH0829443
Kind Code:
A
Abstract:
PURPOSE: To easily provide power to a user with a proper cost.
CONSTITUTION: A windmill is rotated by the wind 2 striking against the windmill. As the kinetic energy of wind increases, the rotating speed 3 of the windmill increases. The kinetic energy is converted into electric energy by means of a generator 5. In this way, the kinetic energy is converted into electric energy by means of a simple device, and an LED 8 and a display unit of liquid crystal or the like are directly driven by the generated energy.
