Efficiency
Currently, ATEGs are about 5% efficient. However, advancements in thin-film and quantum well technologies could increase efficiency up to 15% in the future.
The efficiency of an ATEG is governed by the thermoelectric conversion efficiency of the materials and the thermal efficiency of the two heat exchangers. The ATEG efficiency can be expressed as:
ζOV = ζCONV х ζHX х ρ
Where:
ζOV : The overall efficiency of the ATEG
ζCONV : Conversion efficiency of thermoelectric materials
ζHX: Efficiency of the heat exchangers
ρ : The ratio between the heat passed through thermoelectric materials to that passed from the hot side to the cold side

Famous quotes containing the word efficiency:
“Nothing comes to pass in nature, which can be set down to a flaw therein; for nature is always the same and everywhere one and the same in her efficiency and power of action; that is, natures laws and ordinances whereby all things come to pass and change from one form to another, are everywhere and always; so that there should be one and the same method of understanding the nature of all things whatsoever, namely, through natures universal laws and rules.”
—Baruch (Benedict)
“Never hug and kiss your children! Mother love may make your childrens infancy unhappy and prevent them from pursuing a career or getting married! Thats total hogwash, of course. But it shows on extreme example of what state-of-the-art scientific parenting was supposed to be in early twentieth-century America. After all, that was the heyday of efficiency experts, time-and-motion studies, and the like.”
—Lawrence Kutner (20th century)
“Ill take fifty percent efficiency to get one hundred percent loyalty.”
—Samuel Goldwyn (18821974)
