I think your "English as a second or other language (in others)" bug may have bitten you again. maybe not. I didn't read it that way, and on rereading only see that as a marginal reading at best.

VM can use waste heat to produce refrigeration directly. No steam turbines being injured in the process. Nor laws of Physics. Still can't really see how you get to PMM's in the above. Maybe ... .
