First Superconducting Transistor Created
holy_calamity writes "New Scientist reports that the first working superconducting transistor has been created, by researchers at the University of Geneva. Field effect transistors with zero electrical resistance would allow much faster operations. Only drawback is they need to be supercooled, something that may be addressed by improving the materials used."
At 0.3 kelvin - just above absolute zero - these electrons flow without resistance and so create a superconductor.
So my stock fan won't quite cut it this time?
but will it blend?
We're still decades (centuries?) [sic] away from room temperature superconductors.
Why would that be? After all, cold-fusion is already a reality!

Is it just my observation, or is eldavojohn an idiot?
I'm thinking "The Blue Quench of Death", myself.

So you're saying we could have something to market in 5 but possibly up to 10 years?
No sig for you!!
Back in the 80s, I remember LN pricing (in commercial/industrial quantities) being around $0.05 per liter (roughly $0.20 per US gallon). This FAQ suggests that the price is now around $0.50 per gallon in quantity.
...which makes it significantly cheaper than gasoline. Here's a thought: I wonder how much energy is released as it boils, and how that compares to a gasoline combustion engine. Sure, maybe we'd need more liquid volume, but it's cheaper per unit volume... and its not a Greenhouse gas either - it's 79% of the atmosphere already!
I don't like liquid nitrogen. It hurts my teeth.
