The document describes a regenerative acceleration generator (ReGenX) technology created by Potential +/- Difference Inc. that allows electric vehicles to recharge their batteries while driving or accelerating. Several tests of the technology were conducted by independent third parties and labs, with positive results. The technology has piqued the interest of automakers, government agencies, and academics. However, some experts note it appears to violate laws of physics and more study is needed to understand how it works.
