1. A phase change device for controlling temperature within an environment, comprising:
- a means for changing phase that changes from a liquid to a solid and back to a liquid at a desired phase change temperature;
a shape-stable means for absorbing the means for changing phase in its liquid form, so as to absorbed into the means for absorbing at greater than about 91 percent by volume of the means for absorbing, and at greater than about 98 percent by weight of the combined means for changing phase and means for absorbing; and
a protective covering encasing the means for changing phase and means for absorbing.
