Erik Koepf, a doctoral candidate at the University of Delaware, is working on a solar reactor project that produces hydrogen from a chemical reaction causing sunlight to split water, but its efficiency is still unknown. In March, he'll be traveling to Zurich, Switzerland to test the reactor at full power for the very first time. From there, we'll be able to see if this solar reactor will serve as a stepping stone to better solar technology or if it's a complete dud.
