“Because,” said Aletha, smiling, “you aren’t a Doctor of Human History with a horse-raising husband and a fondness for ice cream. Even so, a technician was needed to break down the problem here into really simple terms.” Then she said, “I think Bob Running Antelope might approve of you, Mr. Bordman.”
Bordman fumed to himself.
“Who’s he? Just what does that whole comment mean?”
“I’ll tell you,” said Aletha, “when you’ve solved one or two more problems.”
Her cousin came back into the room. He said with gratification:
“Chuka can turn out silicone-wool insulation, he says. Plenty of material, and he’ll use a solar mirror to get the heat he needs. Plenty of temperature to make silicones! How much area will we need to pull in four thousand gallons of water a night?”
“How do I know?” demanded Bordman. “What’s the moisture-content of the air here, anyhow?” Then he said vexedly, “Tell me! Are you using heat-exchangers to help cool the air you pump into the buildings, before you use power to refrigerate it? It would save some power——”
The Indian project engineer said absorbedly:
“Let’s get to work on this! I’m a steel man myself, but——”
They settled down. Aletha turned a page.
