The experimental set-up and technical aspects for charging a thermal energy storage (TES) of a proposed solar cooker at constant temperature and variable electrical power are presented. The TES is developed using a packed pebble bed. An electrical hot plate simulates the concentrator which heats...

The spatial extent (SE) of the focal point (FP) of a parabolic dish reflector has been determined using a laser diode as a source of light. The laser diode measurements were compared with those taken using a Gardon radiometer where the sun is the source of light. This was done in order to...
