Uncategorized Meissner Effect – amazing stuff July 24, 2007 bigpresh 6 Comments Now this video is cool: It’s a good demonstration of the Meissner effect in action.

That technology is very old, its the basis of a super-conductor generator. Providing its cold it will keep going forever as such.
There was a nice variation of this on the Absolute Zero two-parter on BBC4. They had a supercooled puck running around an oval track of magnets. Only lasted until it warmed up. http://www.bbc.co.uk/bbcfour/documentaries/features/absolute-zero.shtml Scientists have cooled stuff to a fraction of a billionth of a degree above absolute zero. That’s pretty amazing.
@Steve – hmm, that Absolute Zero sounds interesting. Oh, and is it wrong that I read your comment as “They had a supercooled duck running around…” the first time I read it? :)
@bigpresh – I’m sure Absolute Zero will get repeated. Most stuff on BBC4 does. As for your relationship with ducks, I’d rather not know. Some of the science is pretty weird when you get into superfluids and Bose-Einstein condensates

@Tony – yup, I know, but it’s an impressive demonstration of it.
