Abstract: A mutual-rotating power system for converting solar energy and wind energy into kinetic energy includes a plurality of rotary power mechanisms. Each of the rotary power mechanisms includes an upright fixed shaft, and a rotary device including a plurality of spaced-apart outer blades that surround rotatably the fixed shaft. Each of the outer blades of each of the rotary power mechanisms and each of the outer blades of an adjacent one of the rotary power mechanisms are configured to have magnetic repulsion therebetween when they are rotated close to each other, thereby driving the rotary devices of the adjacent ones of the rotary power mechanisms to rotate in first and second rotational directions.

Abstract: An energy converting system for converting wind energy into kinetic energy has at least one energy converting mechanism that includes a fixed shaft unit including an upright fixed shaft, a windmill device, an air compartment, and a purifying device. The windmill device includes a windmill unit disposed rotatably around the fixed shaft and including at least two first blades driven by the wind energy. The air compartment is disposed above the windmill device. Rotation of the first blades of the windmill unit results in upward flow of compressed air into the air compartment to thereby allow the solar-heated air to be jetted out of the air compartment in such a manner to rotate the windmill device about the fixed shaft. The purifying device is disposed in the air compartment for filtering out impurities in air before the air flows out of the air compartment.

Abstract: A solar construction board includes a board, a solar energy collector mounted on the board and including at least a heating tube which is filled with a first fluid medium therein so as to absorb solar energy and transfer the absorbed energy to the first fluid medium when exposed to solar radiation, and a solar cell unit that includes at least a solar cell which is securely attached to the board so as to generate electrical current when exposed to solar radiation.
