Patent ID: 8745984

Claim:
A multi-stage solar power device, comprising: a light-permeable base plate; a plurality of light-condensing plates including a plurality of arcs with different length in a radial cross section thereof, wherein the light-condensing plates are spaced from each other and arranged under the light-permeable base plate in order according to the length thereof, so as to define a plurality of light-reflecting chambers, and each of the light-reflecting chambers is defined between adjacent two of the light-condensing plates; a heat-conducting tube having a first end and a second end and extending through the light-reflecting chambers; at least one gas turbine disposed in the heat-conducting tube; a gas inlet tube having a first section and a second section, wherein the first section protrudes from the light-permeable base plate, and the second section extends through the light-permeable base plate to connect with the second end of the heat-conducting tube; and a gas outlet tube having one end protruding from the light-permeable base plate, as well as an other end of the gas outlet tube extending through the light-permeable base plate to connect with the first end of the heat-conducting tube.
