Brilliant Light Power, Inc. (BLP), formerly BlackLight Power, Inc. of Cranbury, New Jersey, is a company founded by Randell L. Mills, who claims to have discovered a new energy source. The purported energy source is based on Mills' assertion that the electron in a hydrogen atom can drop below the lowest energy state known as the ground state. Mills calls these hypothetical hydrogen atoms that are in an energy state below ground level, "hydrinos". Mills self-published a closely related book, "The Grand Unified Theory of Classical Physics" and has co-authored articles on claimed hydrino-related phenomena.
