5.4 Renewable energy 5.4.2 Heat
Heating water using a parabolic trough
Absorption of thermal radiation with a solar collector
Principle How can liquids be heated efficiently by solar power alone? This experiment shows how a parabolic reflector works and how it should be positioned to heat a test tube. This involves investigating how the heat of the water in the test tube changes. This technique is used in parabolic reflector solar energy plants, such as the Desert Tec project. The experiment can be set up using equipment from the Renewable Energy school sets EN1 (13287-88) and EN2 (13288-88).

Principle Clamp-on holder 02164-00 is fixed to the aluminium frame of the demonstration board as a holder for a reflector lamp. The absorber plates of solar collector 02165-00 can be used to study how the colour of the absorber affects its function, for example. Magnetic symbols indicating temperature and time can be arranged on the demonstration board.
