They pack in some liquid nitrogen or other coolant around the wires. The engines are going to be used for navy ships and commercial ships and industrial applications. Hopefully the new materials at higher temps will be developed over the next few years and have other superior features. But it took quite a while for the other superconductors.bwhttp://www.blogger.com/profile/07541279438184352860noreply@blogger.comtag:blogger.com,1999:blog-17555522.post-76232807424894153892008-03-22T07:45:00.000-07:002008-03-22T07:45:00.000-07:00I've worked in a lot of labs, but I've yet to have a freezer that could hit -85C. I had a re-circulating chiller once that could get close to -80C. I've jockeyed a few viscosity baths that could hold -65F (-54C). Yes, -85C is positively tropical for superconducting. (People in Chicago are still wearing shots at that temperature, maybe thinking about garbbing a sweatshirt.) But lets not kid ourselves that it's pretty darn cold. <BR/>I'm not all that hopeful for superconducting. At what point does the energy required to reach superconducting conditions break even with the energy saved? I'd rather see a more decentralized grid where we are less dependent on electrons shipped long distances. No matter what you're moving, the farther you move it, the more it costs.Lamont B Dumonthttp://www.thespuds.comnoreply@blogger.comtag:blogger.com,1999:blog-17555522.post-5746542261907117862008-03-18T09:28:00.000-07:002008-03-18T09:28:00.000-07:00Even bigger is the huge announcement in the journal science of <A HREF="http://nextbigfuture.com/2008/03/supercompressed-silicon-and-hydrogen.html" REL="nofollow">room temperature superconductors from highly compressed silicon and hydrogen.</A>bwhttp://www.blogger.com/profile/07541279438184352860noreply@blogger.comtag:blogger.com,1999:blog-17555522.post-14503449519733454972008-03-18T09:23:00.000-07:002008-03-18T09:23:00.000-07:00Awesome, so this is finally going to happen, and in my frame of life time! 0_0<BR/>I have to say that I think this wasnt going to happen ever.Lobo7922http://www.blogger.com/profile/00893503533385321558noreply@blogger.com
