Researchers have been on the hunt for a superconductor that would work at around room temperature, which they consider to be 25 degrees Celsius (77 degrees Fahrenheit) — and according to the patent application, Navy researcher Salvatore Cezar Pais thinks he’s figured it out.

Pais’ application describes a wire consisting of a metal coating over an insulator core. An electromagnetic coil surrounds the wire, and when activated by a pulsed current, this coil causes a vibration that allows the wire to act as a superconductor at room temperature, according to the application.

Many people in Hawaii faced that very question on Jan. 13, 2018. That morning, at 8:07 a.m. local time, the Hawaii Emergency Management Agency sent out an alert advising residents to seek shelter from an incoming ballistic missile.

Even the operator who sent out the alarm, issued over text messages and on TV and radio stations, thought it was real. But it was accidentally sent out during a shift change, and the incoming operator didn’t realize that the alert was part of a preparedness drill.


An erroneous alert about a nuclear attack was sent to Hawaii residents. The ensuing confusion and hysteria revealed that Americans are not prepared.

A swarm of 150 drones buzzed over Maroon 5 singer Adam Levine’s head during this year’s Super Bowl half time show, spelling out the words “One Love.”

It was a dazzling display of drone technology — and military developers in the United States and United Kingdom are increasingly interested in using something similar, but with a very different goal in mind: to surround enemy aircraft, confusing them and forcing them out of the sky.

The Chinese military is looking to procure test systems for magnetized plasma artillery, according to a notice on the People’s Liberation Army (PLA) weapon and equipment procurement website weain.mil.cn last week.

Released on Wednesday and due expire on Thursday, the notice invites tenders for a theory-testing and a launch system for magnetized plasma artillery.

Although the weapon sounds as if it comes from a sci-fi movie, it will probably not shoot high-energy plasma but ultra-high velocity cannon shells.
