QT:{{”
When a radiant energy source is directed at a Crookes radiometer, the radiometer becomes a heat engine.[citation needed] The operation of a heat engine is based on a difference in temperature that is converted to a mechanical output. In this case, the black side of the vane becomes hotter than the other side, as radiant energy from a light source warms the black side by black-body absorption faster than the silver or white side. The internal air molecules are heated up when they touch the black side of the vane.

It’s 1 meter tall when built (tallest lego set ever made) and has 1969 pieces (year of the Apollo 11 launch).
The design was submitted by a couple of LEGO fans, and the company decided to manufacture the set.
Currently sold out, but they will be manufacturing more sets until 2018.
