(насчет сначала посчитать, потом сделать, вы Эйенштейна с е=мс2 вспомните).статьи ясный перец нетути. Кто же вам это в свободный доступ выложит. У них столетний архив по подписке. Гады.Но тут вот у них комментарий естьhttp://physics.aps.org/articles/v5/36Из написанного там:The solid object to be cooled—say a metal electrode—is electrically connected to a warmer object (another electrode). Current can flow between the electrodes through a pair of quantum dots, which could be tiny islands of semiconductor on a nonconducting surface. Each dot acts like an atom that can accept a single electron in one of two energy levels.The team imagines adjusting the energy levels of the two dots so that cold electrons flow from the warm electrode to the cold one, while hot electrons flow in the opposite direction. To make this passage, a cold electron in the warm electrode hops into the lower energy level of the first dot, where it must absorb a photon in order to jump to the lower energy level of the second dot. Once there, the cold electron can hop into the cold electrode to help cool it. Hot electrons make a similar trip in the other direction, hopping across the dots’ upper energy levels and absorbing a photon along the way. A strong light source such as the sun is needed to drive the opposing currents.Cleuren says that one can imagine the electrons are “evaporating” out of the cold object and “condensing” in the warm object, somewhat like an absorption refrigerator. The net heat flow would probably be quite small, but Cleuren imagines that an array of dots could be placed in between the hot and cold objects to increase the heat exchange.Теретически возможно, практически, наверное, смогут сделать, если ну очень понадобится, особенно в мирных целях.
