Observe the power of the Sun. 16cm tall. Glass with metal vanes.

How it works:

  • When placed in direct sunlight, the metal vanes will rotate inside the glass vacuum.
  • The vanes are silver on one side and black on the other.
  • When exposed to light, the black sides will heat up faster than the silver sides, causing a small current of air.
  • The more intense the sunlight, the faster the vanes will spin.
  • No power supply is required, other than the sun. See the science behind thermodynamics in action!
