Abstract:
1. A linear solar heat generating system, comprising: a frame; a solar concentrator installed in the frame and configured to concentrate the sunlight, the solar concentrator comprising a primary mirror installed on the frame and a secondary minor configured to re-reflect the sunlight reflected by the primary mirror and concentrate the sunlight to one point; a heat engine constituted with a cylinder, a piston, and a high-pressure gas, the cylinder divided into a front space and a rear space by the piston, the high-pressure gas housed in the front space and the rear space of the cylinder, the piston being linearly reciprocated by thermally expanding or contracting the high-pressure gas housed in the front space and the rear space of the cylinder by alternately transferring the concentrated sunlight from the solar concentrator to the high-pressure gas; a power-generating unit constituted with a plurality of magnets and a coil, the plurality of magnets installed lengthwise along an outer circumference of the piston, the coil wound lengthwise along an outer circumference of the cylinder, the magnets oscillating according to a linear reciprocating motion of the piston to generate electricity from the coil; and a tilting unit configured to tilt the secondary mirror so that the re-reflected and concentrated sunlight by the secondary mirror of the solar concentrator is alternately irradiated toward the high-pressure gas housed in the front space and the rear space of the cylinder of the heat engine.
