"The Stirling engine is noted for its high efficiency compared to steam
engines, quiet operation, and the ease with which it can use almost any heat
source.
This compatibility with alternative and renewable energy sources has become
increasingly significant as the price of conventional fuels rises, and also
in light of concerns such as peak oil and climate change.
This engine is currently exciting interest as the core component of micro
combined heat and power (CHP) units, in which it is more efficient and safer
than a comparable steam engine."

"Other suitable heat sources are concentrated solar energy, geothermal
energy, nuclear energy, waste heat, or even biological. If the heat source
is solar power, regular solar mirrors and solar dishes may be used."

In theory perhaps, but I really wonder if that is true in real life.


True, but the Stirling has a low power density, which means it gets very big to
produce significant amounts of power.  This is especially true is a low-grade
heat source is used because the heat transfer surfaces must become very large.
The Stirling engine is almost 200 years old, yet I have never seen one.  There
are multiple reason why they have neve become common.  .
