Well, what did happen to them??

Dissappointing that you don't actually say what happened to them! I used to follow AMSC. One other interesting product they manufacture is a superconducting motor for navy fast patrol boats.

In their last earnings call they claimed to being filling the first few purchase orders for Conductus wire in multiple use cases?

I think power transmission will not be the main driver for HTSC development. Advances in distributed power generation and storage (solar cells, fuel cells and batteries) will reduce the demand for bulk power transmission. Of course there will always be demand for power transmission, but I think the growth rate will be slower. Application in electrical machines and electronics will be the main drivers.

The press likes to jump on whatever bandwagon comes along, especially if it has a catchy name.  Besides superconductivity, there were Bucky balls, nano-anything, stem cells to cure anything from hangnail to cancer, fusion reactors, breakthrough batteries, self driving vehicles, and now 3D printing.  While we're waiting, we'll have to be content with the latest development in new ways to tweet (or is it twitter?).

Gimme a break: Maxwell's Equations have not been repealed!

Oh, Gimme a Break! Maxwell's Equations have not been repealed!

Look at the illustration of the 3φ transmission cable in figure 1, and calculate the shunt capacitance... And then the shunt reactance at 60 Hz.

This is why we don't use underground power distribution cables except for very short distances.

Of course, we can use DC transmission, at last count up to 250kV for underwater cables, but the inverter losses far outweigh any i²R cable losses.

Thanks!

I needed this kick into my brain (so it started to think ;-) ) to get a clearer picture.

Whatever Happened to Superconducting Power Lines?

Don't worry.

After a squirrel or woodpecker punctures the cryo jacket, the lines will meltdown and FEMA will have yet another fire they can't put out.

Like many of you, I was saddened to hear the news of Leonard Nimoy's death. His Star Trek character Mr. Spock was an inspiration to many of us who entered technical fields.
