You're right Neil.
Yes, it can actually be higher than 80% if all the stars are aligned just right.
I built/have a residential cogen unit, and have the parts to build a second bigger one, so this is not a theoretical, pie-in-the-sky scheme. The first one is broken at the moment. Curse those one-off prototypes.
Finest regards,
troy
