Being able to transport it seems like an important piece of that puzzle.
Production and storage would need to be scaled by many orders of magnitude, but that's merely an engineering problem...right?
CERN can make/store the antiprotons, but not measure them as cleanly as they want because the facility itself introduces tiny magnetic fluctuations. So this is really a story about moving the sample to a quieter lab, not moving toward sci-fi antimatter batteries... for now
