The conversion chain

For a Stirling-based project, the chain is heat source → Stirling engine → mechanical output → generator → electrical load or power electronics. Each transition introduces constraints and losses.

Questions to answer before building

• What is the continuous heat source?
• How will the cold side reject heat?
• What measured mechanical output is realistic?
• What generator and electrical conditioning are required?
• What safety issues arise from hot surfaces, pressure and rotating components?
