Feel free to prove me wrong , but the stirling engine and the bluegen are apples and oranges. The stirling engine is a heat generator that produces electricity as an added benefit, and the bluegen is an electricity generator that produces heat as an added benefit!
From posts earlier in the year I recall that dumping of waste heat is illegal in the EU, therefore do not believe the stirling will be eligible for subsidies.
There was other info aswell; I believe electrical efficiency had to be at least 50% , confirmation required!!!
In other words stirling and bluegen are two different markets!
