in the text of an artical i read (scientests measure coldest temp yet) i spotted this:
[[[At such low temperatures, atoms cannot be kept in physical containers, because they would stick to the walls. Also, no known container can be cooled to such temperatures.
"To circumvent this problem, magnets surround the atoms, which keep the gaseous cloud confined without touching it. To reach the record-low temperatures, the researchers invented a novel way of confining atoms, which they call a "gravito-magnetic trap." The magnetic fields acted together with gravitational forces to keep the atoms trapped."]]]
Now im not a scientist but I was under the impression that one of the biggest hurdles to developing fusion power was containing the plasma. Has this changed?
