Heating of the heat carrier circuit in the parabolic mirror grooves of solar farms can also be performed by heat sinks of an integrated thermopile, in order to gain additional thermoelectric energy. Firstly, after clarifying the beam focussing, which is uneven with parabolic mirrors, an even beam focussing that is more favourable for thermopiles is proposed by means of a trough mirror whose envelope is to be found by a tangent construction. Secondly, an improved limb construction, having trapezoidal sheets that can be produced economically and have a heat flow that is braked in the direction of the heat sinks, permits the principle of thermopile series connection to be abandoned, so that the irradiated partial circumference of a polygon gives rise to a novel generator rod. In this construction, the continuous alternation of p- and n-material of the trapezes positioned next to one another in each layer achieves, in conjunction with an identical alternation of material in the layers added behind one another, a multiplication of the increasing voltage by comparison with the voltage addition in thermopiles. Thirdly, the aim is to spare the extensive heat carrier/oil circuit customary in solar farms and the conventional power stations by performing the recooling of the heat carrier not in a power station but in the shade of the long trough-shaped solar mirrors by thermoelectric power generation. This task is taken on by a battery of polygonal piles in which the passage of heat taking place in the limbs is forced by round rods installed at the solder joints without secondary inputs or outputs, which cause losses, flowing only between the heat source and heat sink.
