Solar Radiometer £15 each
The smallest sun power plant in the world.
The Radiometer, also known as a light windmill, is an instructive physical object for demonstrating a theory which was invented by the English physicist Crooks over 100 years ago.
This small physical and technical miracle shows you in a
simple way how this 'smallest sun power plant in the world' converts light into
energy and how we are able to use the sun as a source of energy in the future. 
Depending on the power of the light a rotation of 3,000
revolutions per minute can be reached by the radiometer, which is a technically
interesting and amusing article for the modern home.
Fascinating for all ages...just put it on the windowsill and watch it Wizzz!!!
