A solar assisted microturbine utilizing a photothermal mechanism for reducing clean energy generation costs and impacting climate change

A solar energy concentrator uses microwaves to heat concentric cones of air within the atmosphere. The cones are directed to the sun and internally receive the incoming solar radiation 21. This causes the incoming solar rays 21 to undergo total internal reflection within the cones which act as waveguides, and focus the radiation at receiver 1 which is located at the apex of the cones. The conical shape is achieved by directing a microwave beam through an axicon 17, to produce a non- diffracting Bessel beam to heat up the air layers in the atmosphere to generate a temperature and hence a refractive index gradient therein. The energy from the receiver is utilized to heat air in a microturbine 3, 5. As the concentric cones are nonsolid, equipment costs and total generation costs are reduced. The system may also be used to capture infrared radiation from the earth surface at night.

Three-stage process to generate electricity from ambient power sources e.g. geothermal and solar energy

Claimed is a three-stage process to generate electrical using energy abstracted from ambient energy using prior art methods. In the first stage heat energy (e.g. geothermal energy) is collected, with parallel collection of electrical energy (e.g. wind turbine) and stored. In the second stage the heat energy and electrical energy are surrendered to a heat pump. In the third stage energy drawn from the heat pump is converted into electrical energy.

A system for environmental control includes a hybrid wind and solar energy collection subsystem; a temperature control subsystem having a thermo-mechanical engine; an electrical generating subsystem; a sensor for detecting an environmental condition; and a controller for receiving information representing an environmental condition from the sensor. The controller is programmed to detect a change in an environmental condition, and in response to the change, to selectively connect the hybrid wind and solar energy collection subsystem to one of the temperature control subsystem and the electrical generating subsystem and to selectively disconnect the hybrid wind and solar energy collection subsystem from the other of the temperature control subsystem and the electrical generating subsystem.

Start means installed solar heat drive stirling engine

PURPOSE: A solar energy-driven stirling engine having a start unit is provided to quickly start the engine even if it is repetitively stopped by weather conditions, thereby improving efficiency in generating power. CONSTITUTION: A solar energy-driven stirling engine (1) having a start unit (12) includes a temperature sensor (10), an actuation detecting sensor (11), the start unit, and a control part (13). The temperature sensor at the edge of a solar collecting panel (9) measures the temperature of the solar collecting panel at the heating cylinder of the stirling engine. The actuation detecting sensor comprises an inductive body (11a) and an inductive sensor (11b). The inductive body is fixed to a driving wheel, and the inductive sensor is fixed to a frame. The start unit includes a driven gear (12b), a driving gear (12c), and an idle gear (12e). The driven gear is fixed to the driving wheel. The driving gear is coupled to the driving shaft of a start motor (12a) fixed to a base panel (16) on which the stirling engine is installed. The idle gear is actuated by a solenoid (12d) on the base panel, and switches power for the driven gear and the driving gear. The control part firstly detects the operational condition of the actuation detecting sensor when the temperature of the temperature sensor rises, and feeds power to the start unit when the actuation of the actuation detecting sensor does not exist in order to rotate the driving wheel with the driving force of the start motor.
