"As an experimental physicist."
"And as such, you were involved in some phases of the device under discussion?"

"Does the device make use of the Solar beam?"
"It does but—"
"Thank you," interrupted Kingman.
"I'm not through," snapped Farrell. "The Solar beam is not integral."
"It is used, though."
"It may be removed. If necessary, we can have hand-generators supplied to generate the operating power."
