But as superconducting material...Yes, good points.<br /><br />But as superconducting materials improve (latest materials superconduct above 0 F) the cost of cooling them decreases.<br /><br />HVDC is cheap at room temperature, as you say. That is probably the way they will go initially. Better to go with what is feasible now, I agree.<br /><br />Over the long haul, you'll see a lot more superconducting microgrids, local grids, regional grids, and eventually national and continental grids. It's a matter of improving technology. It takes time.al finhttps://www.blogger.com/profile/13739269791915017382noreply@blogger.comtag:blogger.com,1999:blog-24847368.post-79400273201944019092009-10-15T02:40:49.664-07:002009-10-15T02:40:49.664-07:00Good luck with that. Even with Maglev's that a...Good luck with that. Even with Maglev's that are super expensive, the superconductor is only inside the engine/railcar, and the track is not cooled at all. It's like they are trying to cool maglev tracks. Moreover the magnetic field generated by superhigh current is going to induct electricity in nearby moving metals, such as airplanes, birds, and they will parasitically consume some of the energy. In this sense superconductors are not absolute. If there is heavy cylindrical ferromagnetic shielding, that might minimize this loss. <br />HVDC is cheap. All it needs is an un-temperature controlled aluminum wire, which is more abundant than copper. There are some high voltage ionization/leaks, but overall, it's cheap, cheap, cheap, compared to superconductors, especially as you pile on the miles.szilardhttps://www.blogger.com/profile/17647885376105133395noreply@blogger.com
