Whatever Happened to Superconducting Power Lines?
D.K.   1/24/2014 12:49:36 PM
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.

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

Gimme a break: Maxwell's Equations have not been repealed!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 Maxwell's Equations have not been repealed!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

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?).

Distributed Power Generation
Ecspress   1/23/2014 12:27:03 PM
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.

What about STI

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

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 conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
