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.
