Abstract
An apparatus for a space study generates visually impressive fluffy frost effects from the controlled freezing of water. This apparatus has transparent side walls and contains thermal elements and electrodes that can be either round or planar. The thermal elements can be Peltiers. Applying a DC voltage across the electrodes controls the generation of the artful frost effects. The apparatus can also contain, displays, illuminators and other components for enhancing the visual effect.
Claims21
A spatial work of art that comprises:
- a structure separated from an outside environment by at least one glass side-wall;
- at least one target element to be cooled or heated;
- a thermal device for varying the temperature of an inner part of the structure below and above the freezing temperature of water;
- a voltage source;
- and
- at least two electrodes connected to the voltage source, the electrodes capable of generating an electric field for enhancing and controlling frost congealing and formation events.
