Thermal Converters

Nuclear, solar, and chemical sources can all be used to generate heat. Then a thermal converter may be used to change the thermal energy into electricity oi mechanical work. All thermal convenors share a common limitation in the fraction of the heat supplied that can be converted to electric or mechanical power. This fraction, called the thermal efficiency,

where C is some factor characteristic of the converter system involved and (7m„ fmin)/Tmax will be recognized as the Carnot efliciency discussed earlier. When C has its maximum possible value of 1. the efliciency equals the Carnot efficiency, the highest possible efficiency between given temperature limits. In practice C ranges from 0.05 to 0.6.

Thermal converters may be split into two classes. Those without moving parts are called static thermal converters. Those with moving parts are called dynamic thermal converters.

Static thermal converters include thermoelectric systems. The absence of moving parts, seals, bearings, pistons, etc. makes it likely they will have

Solar Stirling Engine Basics Explained

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
