1. A phase change device for controlling temperature within an environment, the device comprising:
- an open-celled foam having macropores and micropores defined therein;
a phase change material selected from the group consisting of salts, hydrated salts, fatty acids, paraffins, and solutions, derivatives and mixtures thereof;
wherein the phase change material is absorbed within the open-celled foam in an amount of about 88 percent to 96 percent by volume of the open-celled foam to make a filled foam, and the filled foam is characterized by the absence of description of the phase change material; and
a protective covering encasing the filled foam.
