Tempra Technology has developed proprietary technology for a self-refrigerating can, which lowers the temperature of a can by a minimum of 30 degrees in just three minutes via an environmentally safe process. When activated, the all natural desiccant contained within a vacuum draws the heat from the beverage through the evaporator into an insulated heat-sink container, and it’s this patented vacuum-power, which lowers the temperature so dramatically and quickly. The company is commercializing the technology and Miller Beer will be introducing Tempra cans by mid-2007. There will be, of course, a price premium, but it’s an incredibly great product offering for camping or fishing, for example.
