Harnessing the power of the sun, the 'Solar Glass' absorbs solar energy to keep drinks at your preferred temperature. The glass is coated with a thin heat-absorbing material on the inside to prevent temperature changes. In addition, the outer layer also has an absorbent coating to take in energy from the sun. With both sides of a cup regulating temperature, the 'Solar Glass' keeps your beverage at a perfect drinking level.

The structure of the cup is built with an inner and outer tube. The inner tube contains the coating and is suspended within a glass outer tube. As a result, the Solar Glass's "solar vacuum heat pipe" design keeps heat from being lost to nearby surfaces.
