1. A solar-powered apparatus, comprising:
a housing (1), a shield panel (5) disposed on the housing (1) and comprising a ratchet pawl and a light-focusing apparatus configured for focusing light, and a transmission apparatus (2) disposed inside the housing (1), comprising eight or more alloy sheets, wherein each of the alloy sheets is a panel bent in a first direction to form a first bent panel and a second bent panel and wherein the second bent panel is further bent in the opposite direction to form a third bent panel, wherein the ratchet pawl contacts alloy sheets expanded by heating at an upper part of the housing (1), and further comprising a solution tank containing coolant arranged at a lower part of the housing (1), wherein the ratchet pawl (13) is disposed on an inner wall of the shield panel (5), a radial length of each alloy sheet (3) is smaller than a distance from the inner wall of the shield panel to the transmission apparatus, and the radial length of each alloy sheet (3) when expanded by heating is larger than the distance from the inner wall of the shield panel (5) to the transmission apparatus (2); and a depth of the solution tank (12) is larger than the radial length of each alloy sheet (3) when expanded by heating. |
