... in base insulation thickness on the system output is studied. For a given bottom insulation thickness, the dependence of its effectiveness on various thermo-geometric parameters is also analyzed. It is observed that a collector with an uninsulated base loses about 60% of the available incident solar...

... last only approximately 3 years. This paper investigates the possible application of thermoelectric cooler (TEC) to increase the heat flow from the core to reduce the temperature at the winding position, potentially providing longer insulation and motor life. For small motors, they can be simply...
