Back to the Future movie fans may remember the term “flux capacitor” as a fictional device that allows for time travel. That device still doesn’t exist, but a University of Central Florida storage technology does use a different type of flux capacitor developed by NASA. While trying to find a way to store renewable energy (like solar and wind) and then use it when needed, UCF Pegasus Professor Jayanta Kapat and researchers Marcel Otto and Ladislav Vesely found that NASA’s Cryogenic Flux Capacitor (CFC) could be part of the solution.
