Abstract: An air conditioning system is provided and including a solar heat generator configured for collecting solar radiation and for heating fluid by the solar radiation and a fluid container coupled to the solar heat generator and being configured to maintain the heated fluid. The system further includes a heat exchanger disposed inside the fluid container and being configured for transferring heat from the heated fluid to refrigerant inside the heat exchanger, the heat exchanger is configured to increase pressure and temperature of the refrigerant. The system further includes a condenser, an expansion member and an evaporator configured to form together with the heat exchanger an air-conditioning cycle.

Abstract: A system for producing electricity from solar energy is provided. The system includes a solar panel for disposing such that solar radiation impinges thereon. The solar panel includes fluid pipes configured for heating fluid therein by the solar radiation. The system further includes a fluid container in fluid communication with the fluid pipes, having an inlet configured to receive heated fluid from the solar panel and an outlet configured to transfer fluid back to the solar panel; a gas line disposed in the fluid container, the gas line having a liquid gas being configured to evaporate by the heat generated by the fluid and to increase thereby pressure in the gas line; and a turbine having a rotor configured to convert rotating motion to electricity, the turbine being configured to receive evaporated gas from the gas line and the evaporated gas is configured to rotate the motor.
