In thermodynamics the highest achievable efficiency is the Carnot efficiency.

There is an overall theoretical limit to the efficiency of any heat engine due to temperature, called the Carnot efficiency.

Devices that convert the fuel's energy directly into work without burning it, such as fuel cells, can exceed the Carnot efficiency.

An important consequence of this ideal cycle is that it does not predict Carnot efficiency.

Indeed, the higher the temperature, the higher the Carnot efficiency, but also the lower the receiver efficiency.

The Carnot efficiency dictates that higher efficiencies can be attained by increasing the temperature of the steam.

Negentropy was considered as controversial because its earlier understanding can yield Carnot efficiency higher than one.

The increased temperature from the higher pressure gives a higher Carnot efficiency.

This large range means that the Carnot efficiency of the cycle is high.

The efficiency of real heat engines is even lower than the Carnot efficiency due to irreversible processes.
