Navy files for patent on room-temperature superconductor
A scientist working for the U.S. Navy has filed for a patent on a room-temperature superconductor, representing a potential paradigm shift in energy transmission and computer systems.
Salvatore Cezar Pais is listed as the inventor on the Navy's patent application made public by the U.S. Patent and Trademark Office on Thursday.
The application claims that a room-temperature superconductor can be built using a wire with an insulator core and an aluminum PZT (lead zirconate titanate) coating deposited by vacuum evaporation with a thickness of the London penetration depth and polarized after deposition.
An electromagnetic coil is circumferentially positioned around the coating such that when the coil is activated with a pulsed current, a non-linear vibration is induced, enabling room temperature superconductivity.
"This concept enables the transmission of electrical power without any losses and exhibits optimal thermal management (no heat dissipation)," according to the patent document, "which leads to the design and development of novel energy generation and harvesting devices with enormous benefits to civilization."

I hope that filing a patent does not expose this to be stolen by say... China or Russia... or did that happen within 20 minutes of filing?

Say "copied", not "stolen". Unless a foreign power was somehow able to simultaneously remove all copies and other memory of the advance from the US, causing it to be lost to the US, it's not stealing. To call it stealing supports ownership propaganda.
Filing a patent on an invention absolutely does expose the invention to copying. The whole point of a patent is to encourage inventions to be shared by making a bargain. In exchange for sharing the details of an invention, the nation will use the force of law to stop copying, or at the least transfer the wealth the copiers acquired to the inventors.

It's not the Russians they're worried about, the Navy is primarily worried about it being stolen by the Army or Air Force.
