Enough already with the Tc.

Indeed. Samples that show symptoms of superconductivity are interesting from a science perspective, but when are we going to get something interesting from an engineering perspective?

Hey folks,
He is doing what he likes. How about YOU do the volume fraction?

Chemistry... definitely not my gig. Spent too much time chuckling at a professor who would scratch his bald head with a whiteboard marker in his hand and leave tracks, so I never learned how to get chemical equations to balance.

Newly discovered material property may lead to high temp superconductivity

Date: July 22, 2016
Source: DOE/Ames Laboratory
Summary: Researchers have discovered an unusual property of purple bronze that may point to new ways to achieve high temperature superconductivity.

https://www.sciencedaily.com/releases/2 ... 212251.htm

"While studying purple bronze, a molybdenum oxide, researchers discovered an unconventional charge density wave on its surface.

A charge density wave (CDW) is a state of matter where electrons bunch together in a repeating pattern, like a standing wave of surface of water. Superconductivity and charge density waves share a common origin, often co-exist, and can compete for dominance in certain materials."

I am still waiting for when I can buy a roll this stuff so I can wire up something really really neat.

How about making it yourself?

[paperburn1]

First off not sure I can, second off is not my job. I've determined long time ago in my job and life is to fix things and make really cool stuff. By the grace of God and liberty of man I have been able to do this for the past 30 years. So I got wait for them to do a good job so someone can manufacture it so I can buy it so I can make some really neat neat stuff. This was not a slam on Joe but a whine by me about seeing something with such great potential just beyond my grasp.

The guy I wish I could get into this discussion is Eddie Sines, one of Richard Hull's HEAS enthusiasts.

Eddie DOES make his own superconductors. He lives near me ... I've been meaning to get over to his place and see what he's up to, but I'd be under an NDA and couldn't tell you anything. But the link below is public.
