Others have claimed to have achieved room temperature superconducting but there is always the question, "Who are these people?" What about if it is the U.S. Navy?

One reason I do not own AMSC is because there is so much money pouring into superconducting. The holy grail of computing, a quantum computer, would become a reality a lot faster if the scientists didn't have to cool their processor to near-zero. While superconducting today requires massive cooling, AMSC can maintain its position as a wire producer using known technology. But the money being poured into superconducting is beyond anything AMSC could hope to muster. When the break comes in cooling to get superconducting, if may do more than disrupt AMSC's wire business.

Here is a snip of a story I found today on phys.org:

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."

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.

This should get a lot of attention in the coming days.
