  • Patent number: 9038387
    Abstract: Thermal energy can be stored in a fluid-based thermal storage system for later use. The stored thermal energy may be derived from steam generated using insolation in a steam-based solar power system. The thermal storage system can store energy when insolation is generally available. Alternatively or additionally, the thermal energy may be derived from electricity from the electrical grid. For example, the thermal energy can store energy when the electrical grid has excess electricity available for storage. At a later time, the energy stored in the thermal storage system can be released to heat pressurized water or steam in addition to or in place of steam generated by the insolation. For example, the stored thermal energy may be used in preheating the solar power system during startup, in supplementing steam output of the solar power system, or to replace steam generation during low insolation periods.

    Abstract: The system and method to generate electricity from solar energy by multi-tired solar lenses powering a steam-turbine. An insulated container mounted with convex-lenses emits steam to impact turbine blades. Over the greater solar catchment's area in the space around, larger convex lenses gather solar energy and focus beam to smaller convex lenses mounted on the container. There are various levels of lens placement acting as energy amplifiers to super-heat water inside the container. The steam passes through a directed jet nozzle, releasing to impact the turbine blades. A generator coupled to turbine shaft produces electricity. The steam, upon utilization and condensation is recycled, while still hot, to the container. On a small scale, it can be used as a supplementary power source to solar panels. Larger turbines can be placed anywhere, including offshore platforms, to tap large catchments area using multi-layered hierarchy of convex lenses.

  • Patent number: 8671685
    Abstract: The invention relates electrical power generation using renewable sun energy in a Microturbine Sun Tracker (MST), a system for useful electrical output power that combines a Concentrated Solar Energy (CSE) with a closed cycle Microturbine powerplant. The solar light ray energy of the CSE is directed into a solar receiver with an integrated closed cycle microturbine powerplant, heating the working fluid of the microturbine to cause the turbine rotor/power spool rotation and subsequent output electricity. Also the (MST) system combines the dish form (CSE) and the closed cycle microturbine powerplant to a common frame that incorporates a single axis 360° rotation capability and secondary declination tilting capability.
