The efficiency is equal to Carnot efficiency
which depends only on hot and cold cylinder temperature.
The efficiencies of any criteria of any order always fall between two extremes--the Carnot efficiency
and the Curzon-Ahlborn efficiency.
and we immediately see that [eta] approaches the Carnot efficiency
, [[eta].sub.c] = 1 - [T.sub.c]/[T.sub.h], for long cycle times (T [right arrow] [infinity] ).
Their engineers I met, were unacquainted with MHD generators and gasped at the carnot efficiency
It is visible how much the ratio [eta]/[[eta].sub.c] (cycle efficiency to Carnot efficiency
) increases as [T.sub.H] increases and [T.sub.L] decreases.

Borealis noted that "almost any form of fuel could be used to generate the heat" and projected that power chips could achieve 80 percent of Carnot efficiency
Finally, a Figure of Merit was calculated, based on the Carnot Efficiency
for any refrigerator.
In contrast, magnetic refrigeration can potentially achieve 70 percent of the theoretical Carnot efficiency
if the losses are kept small when changing the applied magnetic field.
Using the EPA CAP database as an input, recoverable power (the amount of electricity that can be generated from waste heat) was calculated for each individual source using available waste heat and modifications to the Carnot efficiency
under assumptions described below.
(At temperature T, the maximum increment of work for a heat interaction dQ is proportional to the Carnot efficiency
at that temperature, where Carnot efficiency
is the same as the exergetic temperature defined above,
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.
