Curious, instead reviewing the work cited, people here goes on reviewing the author.
Well, he is a well-known expert in thermodynamics, their works are cited by other thermodynamicians and his book in thermodynamics of irreversible processes is published by Dover classics.
He has received Galilei Gold Medal 2009
And with a simple search in google scholar I can find
The thermodynamics of endoreversible engines

It is difficult to believe that are not peer reviewed...
