  • Solar powered magnetic support for display
    Patent number: 6275127
    Abstract: An intriguing and educational display structure (2) includes a translucent earth globe body (3) suspended by energy derived from solar cells (14) integral to the globe. The globe is suspended by magnetic forces between magnets within the support assembly (10) which is controlled by a servo system substantially integral to the globe and powered by the solar cells (14). The servo mechanism can be made to launch and land the suspended globe in response to changing levels of illumination. Energy can be stored within the globe to power occasional periods of suspension, even in very low light levels.
