International audience; The objective of this paper is to utilize wasted heat and hot pressurized air from the exhaust duct of the generator in generating station to produce electricity. This heat and exhaust air is produced due to two types of losses i.e, core losses and copper losses inside generator and its temperature gradient with respect to the external environment. To accomplish this task a hybrid system consisting of Thermoelectric Cells and Wind Turbine assembly is designed in which Thermoelectric Cells produces electricity using the wasted heat based upon the Seebeck effect while the wind turbine generates electricity due to high speed wind striking its specially designed blades according to the modern Aero-Dynamical designs. This hybrid system will work in parallel with the main Generator acting as auxiliary electricity generating source. This system will provide improved results at higher temperature differences and high pressure of wind.

International audience; The main objective of this paper is to introduce the concept of novel flat plate solar geyser with integrated heat exchanger and open loop passive system.The heat exchanger acts both as collector for solar radiations and as a heat exchanger its self for cold water beneath it. Contrary to the conventional flat plate solar collectors, water is in direct contact with the collector or flat grooved heat exchanger. A safety control box is installed to minimize hydraulic pressure of cold water reservoir on the flat grooved heat exchanger as contrary to tube a plate cannot sustain high pressures. The heat exchanger has circular grooves which adds in sustaining hydraulic pressure, increase heat exchanger exposed area to the sun and also cause turbulence in flowing cold water to increase heat rate. A special exit system for hot water is used having a float tube which enable user to withdraw hot water without pressure of cold water from cold water reservoir.
