Two ways to use a temperature difference

A Stirling engine creates mechanical work that can drive a generator. A thermoelectric generator produces electrical power directly from a temperature difference without the same moving mechanical system.

Engineering tradeoffs

Output, efficiency, temperature range, moving parts, cost and application requirements determine which approach makes sense.
