Qiao Wen spread the reserve coil drawing across the design room table and weighted its corners with brass fittings. The outer loop would sit beside a station’s anchor furnace. If the anchor needed inspection, the coil could hold a small amount of current long enough for the crew to close a valve or move a tool. A second set of coils might bridge a short movement window at the central line.
“May,” Qinghe said, tapping the measurement column. “The number is estimated. We have not built this assembly.”
Qiao nodded. He drew a line beneath the load assumptions and wrote provisional beside the duration. “If we change the number of coils or the current, this figure changes. We cannot take a small test and multiply it into a storm claim.”
Yan sat opposite them. He studied the curve where the central line bent toward the reserve bank. “Could this carry the barrier if I had to leave the furnace?”
“It can carry a brief interval,” Qiao said. “It cannot replace a living anchor indefinitely. The current has to go somewhere, and the coil will run down or overheat under a sustained load.”
“And we have not connected one,” Qinghe added. “The central assembly remains a drawing.”
