"We're finding ways to speed up the purification process," said Ryan Gott, a doctoral candidate in aerospace engineering at UAH who will present the research next week at the American Physical Society 71st Annual Gaseous Electronics Conference and the 60th Annual meeting of the APS Division of Plasma Physics, which will take place Nov. 5-9 at the Oregon Convention Center in Portland.

"In theory, if this technology can be developed in a real-world, practical system, it would be able to purify water at lower costs than current methods can," Gott said.
