Did A US Navy Scientist Just Invent A Room-Temperature Superconductor? (phys.org) 212

Posted by EditorDavid from the saving-electricity dept.
"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.

We got a big wave of them when physics went from being mostly wrong to mostly right, but over the last half century we have generally been finding that our knowledge, while still incomplete, is so interlocking and well supported that there is less and less room for something really groundbreaking.

      Ever had a patent? I've got 24 issued (and more pending), and in several cases I was denied for lack of proof of results - meaning I had to provide additional details in the disclosure including measurements to prove it actually worked. At least as rigorous as a scientific journal.

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.

    Patents are for fairly obvious, minimally useful inventions and/or junk. Real interesting discoveries are published as scientific papers for peer review. Money and control, the purpose of patents, are not what motivate the best minds. It's a passion for the science, the process of discovery, and possibly of fame for changing the world that seem to drive it. And you don't need patents for that.
