Thermoelectric temperature control

Thermoelectric temperature control is the use of the thermoelectric effect, specifically the Peltier effect, to heat or cool materials by applying an electrical current across them.[1] A typical Peltier cell absorbs heat on one side and produces heat on the other.[1] Because of this, Peltier cells can be used for temperature control.[1] However, the currently use of this effect for air conditioning on a large scale (for homes or commercial buildings) is rare due to its low efficiency and high cost relative to other options.[1]
