The book opens with a man being shot dead in St Peter's Square as the Pope is addressing the crowds. The man had been trying to reach the Pope with a desperate message. In his briefcase was found a ping pong ball that bounced continually, a cigarette lighter, and a letter.
The ball and the lighter were fueled by a new energy source, the last gasp of a dying human. A French scientist named Mathieu had figured out how to capture the gasp. When contained, the gasp would beat itself against the walls seeking to escape, which is what powered the devices.
On the one hand, this is a free power source that can raise the standard of living of the third world, making life better for everyone. On the other hand, these are human souls condemned to eternal imprisonment, a kind of damnation. Will the desire for gain and national glory outweigh the desire to do right? Can Communist countries, which acknowledge no religion, admit to the afterlife of the soul?
The major governments are in a race to scale this technology up, to make a power plant fueled by thousands of gasps. There are complications. The humanity of the imprisoned souls "leaks" out, causing nearby workers to experience visions of great art, music, or religious figures. An industrial accident in China caused the plant to suck the souls out of living humans, living them alive, but "like animals."
This is a very odd book. It raises ethical and philosophical questions. It deals with what it means to be human, and other "big questions," but it is essentially comic. The characters, including leaders from assorted countries, are shallow caricatures. It is almost a farce of international misunderstandings, skewering the politics of the day (1973). It was probably much funnier at the time. Now it is interesting in a historical way.
In the race to the big conclusion, the action was sometimes confusing. What exactly was happening? The writing was sometimes more clever than clear, and the cast of characters was large. It was certainly interesting, and unique.
