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."

What’s the use of a lossless conductor system if you have to put power into it (through the “electromagnetic coil”) to get it work? Why haven’t the major media outlets picked this up?

Let’s say I’m the Navy and want to make a stinking huge ultra sonic rail gun. If they could significantly reduce the coil resistive losses and therefore heating they could shrink the copper and increase the number of windings. Even if this takes energy, the result may be still be far more efficient than existing techniques. Maybe it has other drawbacks, but the requirement of power in to get greater efficiency isn’t one of them. Think lasers and high efficiency ultra bright LEDs.

Maybe the energy for the electromagnetic coil is less than the losses due to electrical resistance by NOT having superconductivity.
If not, then just power the electromagnetic coil with cold fusion.
The lower I set my standards the more accomplishments I have.
