Re: recuperator == heat exchanger
Those numbers, at least for water, are wrong too.
Back around 1990 Vestkraft in Esbjerg passed 50% efficiency on pure electricity production, using coal. Of course most production in Denmark is combined heat and power, but even so 45% was regarded as normal efficiency for electric only mode.
I was at a job interview with one of the power generation companies and learned they were working with producers of ion exchange resins to improve the water quality.
