About Hight Specific Power Stirling Engine

I think high specific power stirling engines as follows.

• the engine that generates high power by smaller swept volume
• the engine that generates high power by lighter engine weight

If you want to get more power, the easist way may be larger engine or higher heat temperture. But each approach cause larger swept volume or heavier engine weight. So I think high specific power stirling engine is the engine that power by swept volume or power by engine weight is high.
