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?).
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.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
