## Carnot Efficiency
The Carnot efficiency is the theoretical maximum efficiency any heat engine can achieve operating between two temperatures.
### Formula
**eta = 1 - T_cold / T_hot**
Temperatures must be in Kelvin. No real engine can exceed this efficiency due to the second law of thermodynamics.

计算示例
A heat engine operating between 600 K and 300 K.
- eta = 1 - Tc/Th
- eta = 1 - 300/600
- eta = 1 - 0.5
- eta = 0.5 = 50%
