Unfortunately, they are also extremely potent greenhouse gasses, with a short-term impact several thousand times that of carbon dioxide.<\/p>\n<p>Alternate technologies have been tested, but all of them have at least one major drawback in comparison to gas compression. In a paper released in today\u2019s issue of Science, however, researchers describe progress on a form of heat pump that is built around a capacitor that changes temperature as it\u2019s charged and discharged. Because the energy spent while charging it can be used on discharge, the system has the potential to be highly efficient.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Various forms of heat pumps\u2014refrigerators, air conditioners, heaters\u2014are estimated to consume about 30 percent of the world\u2019s electricity.
