Carnot efficiency [kär′nō i′fish·ən·sē]
(thermodynamics)
The efficiency of a Carnot engine receiving heat at a temperature absoluteT1and giving it up at a lower temperature absoluteT2; equal to (T1-T2)/T1.

The upper limit on efficiency for all Rankine cycles is the Carnot efficiency, which is proportional to the difference between the vaporizing and condensing temperatures as shown in Equation 4.

Present commercially available thermoelectric devices operate at about 10% of Carnot efficiency if used as home refrigerators, whereas compressor-based refrigerators usually operate at about 30% of Carnot efficiency.

We investigate a small-scale Brownian heat engine working between two temperatures Tc and Th, where naively one might expect Carnot efficiency but on rigorous examination is found to be untrue due to the counter intuitive role of thermal fluctuations.
