frankly i dont know much about anti-matter or super conductors.....i just read an into-level topic on anti-matter and had a thought. the main concern while developing an energy source is that its feasibility should be considered....right? and the problem with anti-matter is that it takes too much energy to produce and then store it. i was just wondering whether it can be stored in a superconducting magnetic tube? i mean there are no losses in a super conductor and consequently the magnetic field will be able to store it easily . that is what i was thinking. has anyone done this thing at cern or anywhere else yet?
