About Us
Gravitational Energy Corporation (GEC) incorporated in July 2007 as a C-Corp. by Bruce Feltenberger and Art Drentlau.  Mr. Feltenberger, GEC’s president and inventor of the Feltenberger Pendulum technology, has assigned GEC the rights to develop, manufacture and market the technology.  The Feltenberger Pendulum technology has one US Patent issued (US Patent No. 7,735,386), one US Patent pending, and one Patent Cooperation Treaty (PCT) pending. Prior to incorporating GEC, three years of design, research and development by Mr. Feltenberger, Mr. Drentlau and their chief engineer Matthew Butrick led to the development of several prototype machines of various sizes and capabilities to give a thorough understanding of the Feltenberger Pendulum technology.  As a result, GEC now has one commercial product, the GP210 general purpose pump.
