Saturn Globe

This globe, which turns without requiring any support, runs on either daylight or artificial light and on the energy of the Earth's magnetic field. Its slow movement allows one to watch and contemplate the beauty of Saturn. The globe is made up of a transparent acrylic exterior sphere, within which a second liquid-filled sphere is placed. It is on this interior sphere that the image of Saturn is overlaid. A layer of liquid of equal volume to that of the interior sphere floats between the two spheres. The magnet placed in the interior sphere is calibrated to the Earth's magnetic field. It is activated by photovoltaic cells. Daylight or artificial light cross the walls of the two spheres and hit the solar cells, thereby enabling the interior mechanism to collect the energy stored in this light. It is this energy which powers the propulsion system. This globe does not require electrical connections, batteries, or any particular mechanism to ensure that it keeps turning. Comes with an acrylic stand.
