U.S. 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 yesterday.
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.”
No data was included in the patent documents.
A room-temperature superconductor is a material that is capable of exhibiting superconductivity at temperatures around 77 degrees Fahrenheit.
Current superconductors work when cooled near absolute zero, and the warmest superconductor, hydrogen sulfide, works at -95 degrees Fahrenheit.
Others have claimed to have invented a room-temperature superconductor in the past. Last year, two Indian scientists claimed to have made a room-temperature superconductor using particles of gold and silver. Other physicists are using pressurized lanthanum and hydrogen.
TechLink, the Department of Defense’s national partnership intermediary for technology transfer, can help innovative businesses access the technology so it can be developed into new products.
Through technology transfer, DoD inventions are made available to businesses and entrepreneurs for use in new products and services.
The first step is to navigate the license agreement process, which TechLink will help companies do at no charge.
A license confers the right to practice the invention for commercial purposes and often includes related data and technical knowledge, as well as intellectual property rights in the marketplace. License fees paid to the Navy are typically negotiated.
