I have read a report one experimental fuel cell unit installed in

a conventional combustion-based power plant that typically generates
electricity at efficiencies of 33 to 35 percent".


That is typical of an old station running coal or gas, built to 60's
standards. Noit a modern set.


The report was quite recent, like a couple of years old.


*shrug* maybe people aren't too bothered about efficiency and still
build cheap gas powered sets.


*more shrug* Maybe 60% is reached in the occasional "flagship" power
station. I think it is exceptional.
