First, fusion research failed to progress as quickly as expected, so there were no power stations producing streams of surplus plasma to fuel fusion-torch recyclers.

ECONOMIST: Nuclear waste

On earth, a magnetically confined plasma is what nuclear-fusion researchers wrestle with in their search for a clean source of energy.

ECONOMIST: Hot stuff

This is a tiny bubble of plasma that might be made so hot that it could initiate certain sorts of fusion.
