Heat Harvest is the brainchild（脑力劳动的产物）of two students who attended a two-week workshop at a “future-living lab” in Copenhagen（丹麦首都哥本哈根）called Space 10.

Sergey Komardenkov and Vihanga Gore, from the Copenhagen Institute of Interaction（互动）wanted to design a piece of furniture capable of turning wasted heat back into electricity.They also forecast that the technology could be inserted in portable pads. The table would use thermoelectricity（热电）to capture wasted heat and convert it into electricity.

A warm item would likely be placed on a thermoelectric generator, which is not visible in the conceptual images, while a phone would be placed on, or near, a wireless charging pad to power-up（加电）. The technology incorporated（使合并, 并入）in the design uses basic physics by exploiting the differences in temperature between two surfaces to generate electricity.

On an atomic scale, the temperature difference causes charge carriers in the material to diffuse（传播）from the hot side to the cold side of a generator.

So electrons at the hot end will have more energy than those at the cold end and will move around more towards the cold end, The Naked Scientists explain. Eventually the cold end becomes more negatively charged and the hot end more positively charged. This phenomenon, where a temperature difference can create a voltage（电压）, is known as the thermoelectric effect.
