"What is it sergeant?"
"There's an unusual RF signature being detected by a mid-Atlantic sonder buoy sir."
"Well, if I didn't know better sir, I'd say it was a fusion signature. I did some work with a Stellarator in Princeton before they shut it down. This has a similar radio frequency signature."
"Should I be concerned?"
"The Princeton Stellarator only ever managed a few seconds of operation. There's one in Germany that I think has done a few minutes. This signature started thirty minutes ago."
"I am concerned. Someone get the admiralty on the line right now!"
