The German Radiometer

A radiometer is a very simple solar power plant.
The English physicist, Edward Crooks, built the first radiometer to demonstrate with simple physics and movement how light can be transformed into energy.

The black and silver coated solar wings are suspended in a semi-vacuum state of a sealed glass ball and when exposed to radiant light-sunlight or incandescent light, the black coated sides of the solar wing absorb more light and energy than the silver sides. Air pressure builds on the black side of the wings as the absorbed energy raises the temperature of the air molecules on that side and the increased air pressure causes the solar wings to spin within the semi-vacuum.

Radiometers measure the "radiation" of the light source, the spinning movement intensifies when exposed to stronger light. A radiometer will not spin with fluorescent light.

About Chinese Cloisonné

  Cloisonné, whose history can date back to over 500 years ago, is well-known traditional enamelware. It is actually called the "Blue of Jingtai" as blue is the dominant color adopted for enameling and cloisonné became prevalent during the reign of Jingtai (1450--1456) in the Ming dynasty. Owing to the brilliant color and splendid designs, cloisonne has been highly appraised at home and abroad. Regarding the making of cloisonné, it involves quite elaborate and complicated processes: base-hammering, soldering, enamel-filling, enamel firing, polishing and gilding.
