Peltier effect can be usefully exploited to cool as a replacement for air conditioners which are unfriendly to environment in more than one way. They are noisy with power guzzling compressors and using most often chloroflurocarbons damaging ozone layer. Our challenge is saving power and caring for "passive" heating and cooling which like non smokers have to face because of smokers - inducting passive smoking. If we can have modified, flexible Peltier chips easily embedded into inner lining of our garments, with outer layer based on graphene based composite fibers, we can have a solution where instead of cooling whole lot of volume of buildings and corridors in offices and at homes, we limit that volume to a very small fraction of individual body volume. These can be powered through plug in supplies where one moves and stays and operate on batteries while in transit.
The method of thermoelectric cooling (using the Peltier effect) is useful because it can cool an object without any moving pieces or other complex machinery that isolates the cooler from its ambient surroundings. The devices that are constructed to take advantage of this phenomenon are known as Peltier elements, or thermo-electric coolers (TECs).
The basic ideas from the simple Peltier elements can be connected in series to construct far more complicated Peltier modules (also known as practical TECs), which have greater cooling capabilities. However, the greatest temperature difference between the heat sink and the cool region for a Peltier device is on the order of 50°C.
Common uses for Pelier elements include cooling computer components, especially the CPU.
