"How could I know?” Craven asked. “Somewhere in space."
"They're at the bottom of this,” snarled Stutsman. “Their damned tricks and propaganda."
"We know they're at the bottom of it,” said Craven. “That's no news to us. If it weren't for them, we wouldn't have this trouble now, despite your bungling. But that doesn't help us any. With this new discovery of mine I have shielded this building from their observation. They can't spy on us any more. But that's as far as I've got."
"They televised the secret meeting of the emergency council when it met in Satellite City on Ganymede the other day,” said Chambers. “The whole Jovian confederacy watched and listened to that meeting, heard our secret war plans, for fully ten minutes before the trick was discovered. Couldn't we use your shield to prevent such a situation again?"
"Better still,” suggested Stutsman, “let's shield the whole satellite. Without Manning's ghostly leaders, this revolt would collapse of its own weight."
Craven shook his head. “It takes fifty tons of accumulators to build up that field, and a ton of fuel a day to maintain it. Just for this building alone. It would be impossible to shield a whole planet, an entire moon."
"ANY progress on your collector field?” asked Chambers.
"Some,” Craven admitted. “I'll know in a day or two."
"That would give us something with which to fight Manning and Page, wouldn't it?"
"Yes,” agreed Craven, “It would be something to fight them with. If I can develop that collector field, we would be able to utilize every radiation in space, from the heat wave down through the cosmics. Within the Solar System, our power would be absolutely limitless. Your accumulators depend for their power storage upon just one radiation… heat. But with this idea I have you'd use all types of radiations."
