"Huh? That's a new one on me."
"It isn't electronics," said Channing. "It's sub-etheric or something like that. We'll call it subelectronics for lack of anything else. But we should be able to detect it somehow."
"Suppose there is nothing to detect?"
"That smacks of one hundred percent efficiency," laughed Don. "Impossible."
"How about an electric heater?" asked Arden.
"Oh, Lord, Arden, an electric heater is the most ineffic—"
"Is it?" interrupted Arden with a smile. "What happens to radiation when intercepted?"
"Turns to heat, of course."
"That takes care of the radiation output," said Arden. "Now, how about electrical losses?"
"Also heat."
