If you were rushing to a bookstore or a library to obtain this "savagely funny" and "enormously entertaining" book, as the advertising on the cover calls it, you will be well advised to slowdown and think again.
This book is funny close to the beginning. There are dirty jokes, for men, by a man, and on men, particularly middle aged ones. Then, later, the description how the politically correct hysterics resulted would be funny, if it were not literally true and actually frightening.
Our hero is not only a scientist and a holder of the Nobel Prize, but also first class Don Juan. I might believe that he could have had even more sexual encounters than mentioned, but not about four relationships a year, while married. A relationship needs some time, while getting entangled and disentangled, and ending it all, unless, of course, he carried more than two relationships at the same time.
This book is about creating energy from water and solar energy. It is very educated and well researched.
But there is still a possibility that the whole book is a joke. On us, on the author, and on novel writing generally.
