Silicon compound aims to superconduct at room temperature
EETimes ^ | 3/17/08 | R. Colin Johnson

PORTLAND, Ore. — A new superconducting material fabricated by a Canadian-German team has been fabricated out of a silicon-hydrogen compound. Instead of super-cooling the material, as is necessary for conventional superconductors, the new material is instead super-compressed. The researchers claim that the new material could sidestep the cooling requirement, thereby enabling superconducting wires that work at room temperature.

"If you put hydrogen compounds under enough pressure, you can get superconductivity," said professor John Tse of the University of Saskatchewan. "These new superconductors can be operated at higher temperatures, perhaps without a refrigerant."

He performed the theoretical work with doctoral candidate Yansun Yao. The experimental confirmation was performed by researcher Mikhail Eremets at the Max Planck Institute in Germany.

The new family of superconductors are based on a hydrogen compound called "silane," which is the silicon analog of methane--combining a single silicon atom with four hydrogen atoms to form a molecular hydride. (Methane is a single carbon atom with four hydrogens).

Researchers have speculated for years that hydrogen under enough pressure would superconduct at room temperature, but have been unable to achieve the necessary conditions (hydrogen is the most difficult element to compress). The Canadian and German researchers attributed their success to adding hydrogen to a compound with silicon that reduced the amount of compression needed to achieve superconductivity.

Tse's team is currently using the Canadian Light Source synchrotron to characterize the high pressure structures of silane and other hydrides as potential superconducting materials for industrial applications as well as a storage mechanism for hydrogen fuel cells.

The research was funded by the National Sciences and Engineering Research Council of Canada, the Canada Research Chairs program, the Canada Foundation for Innovation and the Max Planck Institute.

Sigh, done by Deborah Chung several years ago at State Univ of NY, high pressure laminates with NEGATIVE resistance/room temp su-co. Her discovery was BURIED on orders from DC/big oil. See cheniere.org for the story.

Negative resistance? The wires just sat there and created voltage? Kewl!

Good luck to them. There’s a lot of research going on now concerning hydrogen storage.

Yeah, those evil Big Oil guys, instead of buying this revolutionary invention and using their industrial leverage to move it to market and leapfrog their competitors, instead chose to pay off the researcher and everyone on her team to keep it buried. Of course, the amount they would have had to pay her off would’ve had to have been greater than the amount she could’ve made by selling products based on this breakthrough - which would’ve been gazillions - but yet somehow these moustachioed cigar-smoking top-hat-wearing corporate fat-cats managed to make this payoff profitable for both her and themselves. See, that’s why they make the Big Bucks!

Yes, negative resistance. A wire that generates its own voltage. It’s not so hard to believe. I mean, I’ve seen articles about cars that run on water, for whom water is both the input and the output. I’ve seen articles on self-feeding electric dynamo/motor combinations that miraculously spin faster and faster the longer they run. I’ve seen articles on electromagnetic induction coils that move in one direction without propelling any mass by a proportionate acceleration in the opposite direction. Surely if such things are possible you’re not going to question negative resistance, are you?

That’s a joke, right? Seriously, negative resistance? From the site, more power out than was put in? Wow, just WOW, if you really believe that junk.

Sarcasm aside, it actually is possible to achieve power output from the wire itself, assuming you’re breaking the wire down as you do so. That is, if you’ve built a conductor out of some unusual volatile material that will shed electrons when exposed to an electric current, then yeah, your conductor will temporarily give you a surplus of current until such time as it’s completely broken down.

It’s a little bit like making a necklace out of a chain of AAA batteries and then using it to connect two electrodes to one another.

A commonly used concept in Electrical Engineering.

An example would be an inductor (coil of wire) with current flowing though it. Open the circuit and the coil of wire generates voltage.

(fnord!)The SAME ONES who did that with the pill that JC Whitney sold that you dropped in the gas tank and got 200 MPG!

(fnord!) Yes, the VERY SAME people who buried the rights to the JC Whitney water-injecting carburetor!

*nod* It’s true, technically there’s nothing wrong with the idea of negative resistance - as long as you don’t mistake it for net electrical energy generation.

You know, I can't quite put my finger on it, but there's something about your post that makes me highly uncomfortable. :)

Its really a way of explaining how components that absorb energy (inductors and capacitors) give that energy back.

Hahaha. Perhaps I can illuminate you...

I know, I know, it sounds impossible at first, and yet do you know how cooper pair electrons work in superconductivity? Study up on that and you’ll see how the matter wave linked electrons form a boson and thus migrate to the cathode. The bose(love)rule is : with n number of bosons in a given state there is a n+1 enhancement factor for the next boson to join that state. We see this effect
in lasars, gravity, birds of a feather flock together...

Apparently then, Deborah Chung’s high pressure laminate creates a 2 dimensional superconducting layer that converts room air temperature(random motion of heat)into coherent electron current via cooper pairs. I know it sounds weird but that’s what we call Quantum Mechanical weirdness, a big mystery to folks who only live(and think)in the Classical Mechanical world.

If you had one or 2 outside house walls of this high pressure laminate, the current would run your electrical home with just external heat. But it would also help if you INSULATED it more, too.
