HOW IT WORKS
The Rainbow Maker is an ingenious solar energy engine, studied to put in rotation a polyhedron made of crystal. The engine is connected to a series of gears that have the function to slow down (demultiply) the rotation and transfer the motion to the crystal leaning. The scarce energy produced by the solar panel, is amplified by an electronic circuit and a generous coil, so as feed the little electric engine. All the parts mechanical and electric, are visible through the transparent shell and constitute a further attraction during working.
The direct light of the sun performs two functions: produces electric energy thanks to the solar cell, produces the rainbows for light decomposition through the crystal.
To obtain luminous and well-shaped rainbows, is necessary a crystal with high trasparence, without impurity (drops or splinterings), with a perfect geometry. Characteristics obtained with a Swarovski crystal (http://www.swarovski.com/index/), worldwide leader in this field. They are available two versions of Rainbow Maker, with a drop crystal and heart crystal. Depending on the version changes also the colours of the internal gears. |
