Abstract
Abstract A power system for use in converting solar energy into stored energy available as output power capable of operating diverse types of power-driven units, such as electric generators, air conditioners, etc. The power system includes solar heat collector means, a compressor system and power storage means. The solar collector system utilizes the sun's rays to heat a liquid medium, such as a refrigerant or halogen, and convert it into a gas, with the expanded gas being delivered to the compressor system whereby it effects operation of large motor means. The large motor means is integrally connected to a substantially smaller motor means operable to pressurize a compressor gas in accordance with the principle of hydraulic pressurization. The combination of the large and small motor means allows the pressure of the solar heated medium to greatly magnify the pressure developed on the compressor gas, which is transferred to the power storage system. Control means is operatively associated with the large and small motor means and operable to adjust the ratio of pressurization in response to temperature and/or pressure changes in the solar heat collector means. Appropriate valve means, valve operating means and recycling condensors are operatively associated with the compressor system and the solar collector for effecting a continued operation of the power system.
