In collaboration with professor of aerospace and mechanical engineering Peiwen "Perry" Li, they have also found a way to recover and store some of the energy created in the smelting process.

The team is working with Tech Launch Arizona to bring the technologies to market through the startup MetOxs Electrochemical.
