“It is 2070 , an isotope which cannot possibly exist has resulted in the invention of a device which has resulted in the resolution of the energy crisis. It is the electron pump- a source of unlimited energy at no cost. It performs a transfer of electrons with a parallel universe resulting in the creation of unlimited energy in both the universes. One man, Peter Lamont has found proof that the pump is a threat to mankind's existence. Yet, the establishment is unwilling to support him and labels him a lunatic. In the para-universe, a being Dua is also bent on trying to stop the pump and struggling against her own people to do the same. Proof must be found and for that a former fallen radio chemist, Denison goes to the lunar colony to carry out his experiments. He is assisted by a Lunarite tourist guide, Selene who seems to know more than she shows. Will mankind be convinced to turn off the miraculous source ? Will an alternate solution be found? Can Dua succeed? What is Selene's hidden agenda?
Quite an engrossing read from Asimov. Though the beginning is a bit tedious , you do get hooked by the end. Also worth mentioning is Asimov's portrayal of the Para-beings and the Lunarites. Ultimately, it is what goes on in people's minds that forms the crux of the story.”
