Did A US Navy Scientist Just Invent A Room-Temperature Superconductor? (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," reports Phys.org:
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."
Long-time Slashdot reader resistant writes: NextBigFuture says the same individual appears to have made other startling claims that arguably stretch the boundaries of belief, such as a "high-frequency gravitational wave generator" that could supposedly drive a spaceship without conventional propellants as well as an "inertial mass reduction device." Prudence would appear to dictate examining these and other claims by Mr. Salvatore Cezar Pais with great caution.

Description of his invention, and how to make one. A valid patent application must include enough information that someone "skilled in the art" (in this case, physics and materials science) can successfully replicate the invention. If it's not disclosed to that level you can challenge it and have it invalidated.
Browsing at +1 - no ACs, I ignore their posts. So refreshing!
that's not entirely true and it depends on what kind of patent you are filing. Look at the IBM's patent portfolio, there are tens of thousands of bogus obvious stuff patented in their portfolio. The key is to hire experienced patent lawyers to file the patent. They will make sure it will get granted. I used to work at IBM and they have 2 armies of expert patent firms doing this for them. I've read many IBM patents that were totally bogus. For mechanical inventions, I would agree with you. For software patents I would disagree.
Can you find a _single_ reputable physicist or chemist who thinks room temperature superconductors are feasible?
Well, there are these guys. It took 10 seconds of Googling to find that, and there are lots more. If no reputable chemists or physicists believe room temperature superconductors are feasible, there sure are a lot of them wasting their time. The 2016 Nobel Prize in Physics was given to a group of mathematicians and physicists whose research may pave the way towards high-temperature superconductors (as well as a lot more).
Many speculate on the idea
Why do they bother if they all believe it's infeasible? And they clearly do a lot more than just speculate.
but none has demonstrated a practical theory of how to do so.
So your argument is that because no one has achieved it, no one even thinks it's possible? Really?
Given this Navy guy's other patents and the nature of how his invention supposedly works, I'm pretty skeptical that he's done it. I expect that if it's achieved it will be one with some pretty exotic materials and/or complex methods, because if it were easy it would have been done years ago. But assuming it's impossible just because no one has done it is silly.
