Room Temperature Superconductor Patented

Timothy Birdnow

A scientist working for the U.S. Navy has filed for a patent for room temperature superconductor.

This is huge, but the American media doesn't understand it's importance.

From the article:

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."

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.

Superconductivity is a condition where there is no electrical resistance to current flow amd flux flows are eliminated. This property (which normally requires considerable cooling of the conductor) was discovered by a Dutch physicist named Heike Kamerlingh Onnes on April 8, 1911.

Superconductors are wonderful things. An electric current induced in a superconductor lasts forever without a power source. This makes it a dandy material for DC current.

Superconductors have many uses. They are especially good at magnetic levitation, which would be useful in mminimal friction trains and the like. They can be used in electrical generators, improving their efficiency to as high as 99% (froma current of about forty five). This will make generating electricity cheaper and will require far less energy. See here for more on the uses of superconductors.

We have only begun to conceive of ways to use superconductors. And having a room-temperature superconductor is a huge game changer.
