1. A linear solar heat generating system, comprising:

  • a frame;

    a solar concentrator installed in the frame and configured to concentrate the sunlight;

    a heat engine constituted with a cylinder and high-pressure gas, the cylinder divided into a front space and a rear space by a 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; and

    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.
