Small hydropower generator of novel concept, using ferris wheel

A new concept small hydropower generator using a Ferris wheel, comprising:

• opposite supports built up to a constant height from a ground to provide a strong support base of a main rotational shaft;
• the main rotational shaft installed under the strong support base at an upper end between the opposite supports;
• a rotor rotating at a predetermined rotating speed in a predetermined radial range with respect to the main rotational shaft;
• several water filling-then-emptying buckets (“water buckets”) which are arranged around the periphery of the rotor at constant equiangular intervals, wherein the bucket is always horizontally balanced during rotation, and the bucket is filled with a predetermined amount of water to imply a weight when placed at a top center of rotor during rotation while, when placed at a bottom center of the rotor, the weight is removed by pouring out the water;
• a selective water supply device that supplies water drawn from a relatively small scale river or stream to the water bucket located in a center of an upper center of the rotor, wherein, after completely filling one of the buckets with water, the selective water supply device stops water discharge temporarily until the next bucket is positioned;
• and
• a generator installed on one side of the main rotational shaft disposed in a center of the rotor to convert rotational kinetic energy output from the rotor into electrical energy.
