Zusammenfassung:The invention relates to a device for collecting and transforming solar energy into electric and thermal energy. According to the invention, the said device consists of a parabolic mirror (1), which has fixed, in its geometrical focal point, a solar collector (2), which consists of a spherically shaped metallic body, through which there is circulated a thermal medium and which is located inside another spherical emptied body (3) made of glass, the vapours generated in the solar collector (2) being circulated through a turbine (4) which actuates a direct or alternating electric current generator (5), an electric accumulator (6) and, optionally, an inverter (7), as well as a heat exchanger (15) and a pump (16) for pumping the condensed vapours into the solar collector (2), the heat exchanger (15) being, at the same time, a vapour source which drives another turbine (18) for actuating the generator (5), in connection with this turbine (18) there being mounted a condenser (20), and also another pump (19) for pumping the condensed vapours back into the heat exchanger (15), it being also provided with a system of electronic determination of the sun position, consisting of two pairs of photo-elements (8 and 9), located on the circumference of the mirror (1), in order to transmit the tension generated by the luminous flux to a comparator (10) connected to a processor (11) for controlling some servo-mechanisms (12 and 13), for orienting and positioning the mirror (1) so as to collect a maximum of solar energy. Invenţia se referă la un dispozitiv pentru captarea şi transformarea energiei solare în energieelectrică şi termică. Dispozitivul conform invenţiei este constituit dintr-o oglindă (1) parabolică, ce are fixat, în focarul geometric, un captator solar (2) care este constituit dintr-un corp metalic de formă sferică, prin care este circulat un agent termic şi care este amplasat în interiorul unui alt corp (3) sferic vidat, confecţionat din sticlă, vaporii generaţi în captatorulsolar (2) fiind vehiculaţi printr-o turbină (4)care acţionează un generator (5) de curent electric continuu sau alternativ, un acumulator electric (6) şi, opţional, un invertor (7), precum şiun schimbător de căldură (15) şi o pompă (16) pentru pomparea vaporilor condensaţi în captatorul solar (2), schimbătorul de căldură (15) constituind, în acelaşi timp, o sursă de vapori care antrenează o altă turbină (18), pentru acţionarea generatorului (5), în legătură cu această turbină (18) fiind mon
