استخدام الجسم الاسود لتوليد قوة دافعة كهروحرارية

In the present study a Blackbody was use as a thermoelectric source used in range temperatures that reach 260°C, through focusing sun that incident on reflected surface (hemisphere) with radius (R) equal 50cm with convex lens that subject it toward black body with surface area (A) 40 cm2 with distance from center of reflection surface (f) with magnitude 59.72cm and its distance with respect to lens 25cm to obtain the best thermo focusing point to the body, The results indicated the thermoelectric voltage (E) reached to 9.8 mvolt from the theory value which is used with electric heater that given 12.2 mvolt instead of black body in 260°C thermocouple (Iron and Copper) .
