Brief Bio of Douglas K. Furr

Douglas K. Furr owns and operates a production facility in Orem, UT, USA, including lathes, injection molding machines, EDM, CNC machines.

On the side, he enjoys trying various free energy technology designs that seem like they might work.

Doug received a Ph.D. in Mechanical Engineering from Trinity College and University, Sioux Falls, South Dakota.

He has been listed as the PES Network, Inc "Mechanical Engineer" since our founding in November of 2003. Before that, he was involved in our parent company, PerenTech, which was founded to help manufacture and market the Perendev magnet motor. With the inventor, Make Brady's permission, Doug built a 1/4-scale replica of the Perendev Magnet Motor, which we were not able to get to run. Many people have seen photos and a video of that motor. PerenTech subsequently left negotiations with Brady.

Alternative Energy Tinkering

Water Flashlight

Super-Efficient Engine Retrofit

Doug is working on a patented design that improves the performance and efficiency of internal combustion engines.

1/4-scale Perendev Magnet Motor

  • Featured: Magnet Motors > Perendev > Replications >
    Michael MacInnes' Magnet Motor - Michael MacInnes and Amir Abyaneh of Canada have designed what appears to be a working all-magnet motor. A video shows a walk-around of the unit before turning it on. The acceleration is not huge, but it does accelerate. The video title mentions "2500 rpm", which is probably where it reaches equilibrium. (PESWiki; March 28, 2013)


In the winter of 2008, Doug replicated a 1.5-scale version of the MPMM magnet motor.

Gravity Wheel

In August, Doug built a replica of a gravity wheel design by Scott Hall, which turned out to have been propelled by a slight incline in Scott's garage floor.
