Which limit primarily constrains miniature Carnot engine efficiency?

💡 Explanation

Increased surface greatly affects miniature Carnot engines because it increases the area for parasitic heat loss. Therefore, efficiency is limited by increased conductive heat transfer, rather than purely by Carnot cycle parameters.
