Mova Globe (CES 2008) 3,435 Views - Click for Larger Image
The Mova Globe is a remarkable piece of engineering. It is a globe enclosed in a fluid filled clear acrylic sphere. There is an electromagnetic motor within the globe that is recharged by solar cells using the small amount of light that penetrates the globe. The motor spins the globe within the fluid, using the resistance of the earth’s own magnetic field. The Mova Globe will rotate in the palm of your hand!
A small industrial strength magnet within the globe acts as a stabilizer to force perpetual silent rotation of the globe against the liquid. The magnetic field of the real earth keeps this internal magnet in a N-S alignment. Torque from the motor counters the torque generated by the earth’s magnetic field.
Perfect suspension of the globe in liquid recreates the weightless state of planet earth as it travels through zero gravity. The MOVA globe may be 4 lbs and 6-inches in diameter, but the liquid suspension eliminates the appearance of weight completely.
