Robert "Bob" Rohner is an American mechanical engineer from Iowa known for his efforts to build and replicate the noble gas engine developed by inventor Joseph Papp. He is president of the Rohner Group, LLC.
Biography
Rohner is a mechanical engineer based in Iowa with a background in large machinery and controls. Together with his brother Tom Rohner, he owned businesses in Iowa before becoming involved with engine development. Beginning in 1979, the brothers worked closely with inventor Joseph Papp and built engines for him. His brother Tom, who served as a chief software architect at Compaq and Hewlett-Packard, died of pancreatic cancer in 2013.
Work
Rohner's work centers on the so-called "noble gas engine" or Papp engine, a design derived from Joseph Papp, who was granted a United States patent for a noble gas engine in 1984. Papp did not fully disclose the composition of the inert gas mixture used in his engine, and the mixture was considered lost after his death.
Rohner and his brother built the engines shown in demonstration videos associated with Papp's work. After Papp's death, Rohner continued to pursue the technology, and through the Rohner Group, LLC he sought to reconstruct and replicate the design. He and his brother developed an experimental setup they called the Twin Cylinder Dual Piston Engine, which they stated reproduced Papp's process using roughly 200 cubic centimeters of a gas mixture. Rohner has claimed the engine produces energy output several times greater than the electrical input, a claim of over-unity operation that is not accepted within mainstream physics. The work was presented at TeslaTech conferences and promoted through crowdfunding efforts.
