Robert (Bob) Rohner was involved with Joseph Papp, building engines for him.

He's been pursuing the technology since then, off and on.

Presently he is very actively involved in replicating the engine, making great progress.

Bob is not associated with his brother, John, who is also involved in the noble gas engine technology.

    Roberts Rotary Noble Gas Engine Debut - Robert Rohner has built a rotary noble gas engine design by Dannel Roberts, and uploaded a video showing it in operation, demonstrating for the first time this new method of harvesting the noble gas plasma effect. Though it doesn't show power in:out, they do disassemble the engine to show its simplicity. (PESN; May 2, 2013)

    Rohner Group Current Progress on Twin Engine (Noble Gas) - Contrary to John Rohner's history of talking big while showing nothing running, here, Bob shows his "twin engine" setup running, though I doubt it is yet to the point of producing more energy than it consumes. He describes some of the components, shows the drive motor, connected through a one-way clutch, so once the engine starts operating, via plasma, then the drive/starter motor can be turned off.

    Bob Rohner Demonstrates "Plasma Cycle is Not Air Driven" - On September 9, Bob posted a 17:30 minute video showing the assembly, filling, and firing of his noble gas popper unit. No heat was generated, but work was performed in moving the cylinder against a spring and turning a motor from the air cycle created from the piston -- an clever, indirect motor application. We finally have a Bob Rohner page at PESWiki. (PESWiki; September 12, 2012)
