> the ability to generate a stable ring of plasma without powerful electromagnetic fields or vacuum suggests the possible use of plasma structures to store energy, Gharib says.

That seems strange. Earlier in the article it clarifies that the ring is made by squirting water on a crystal and that the ring is maintained by continuing to do that. If you are required to keep squirting water at the crystal to maintain it, is it actually a good storage mechanism? Is the maintenance power draw much lower than the initial creation? How efficient is it?



I think he is saying this structure suggests other possible structures that might be more energy efficient.
