Page 24, On-Road Testing Now Underway

I am performing the on-road testing phase now. I will say that I am impressed so far, even without completing a recorded data set. It is truly amazing to feel the vehicle being pushed along using so very little power, while also decreasing the amount of throttle given to the engine because of the engine load decrease.

The only change I have made to the PIE is the addition of a switch and relay to control the PIE from the driver’s seat.

In the shop, I am preparing for PIE 2.0. I deliberated heavily about the planetary gear sets. I would like to replace them with machined gears which would run quieter and smoother, but I will stay with the simple fabricated gears for now. I already have parts made to fit the fabricated gears, so this will save the time and the expense of rebuilding some components.

I seriously thought of upgrading everything, bearings, plates, gears, weights, etc. but cannot justify that at the present so it will have to wait for version 3.0 or higher.  I am, however, planning on running weights on both sides of the flexplates. This should allow for heavier weights and higher RPMs which will both equal more thrust! 

Page 23, Thornson Book, Video & Patent

Because the PIE is so closely bound to the many years of dedicated work of Brandson Roy Thornson, I am providing some of the most pertinent info I have for anyone interested.

I have uploaded copies of the book “Inertial Impulse Propulsion Engine of Brandson Roy Thornson”, the “Thornson Physics” full movie-length video, and the Thornson U.S. patent. 

They are saved to a Google Drive that I only use for sharing information. 

Here are links to each of these works,. 

Please note: The video’s quality is rather poor at times. It was recovered from old VHS tape format which was degrading in storage.

Also note: The book seems a bit disjointed, or out of order. This is exactly as it was published and delivered to me. The information in its pages is priceless and needs to be preserved.




To the best of my knowledge none of these works are currently protected by an active copyright. If anyone knows differently, please leave it in a comment and if found to be true, the work will be removed immediately.

Page 21, A Resounding Successful Test Drive!!!

May 13, 2020

The very first “real world” test drive/road test has been completed, successfully!!! This is a major milestone for the PIE. This first road test was done with no instrumentation installed in the subject vehicle, so there is no empirical data for the record. I also did not install a remote switch or camera.

The next round of testing needs to include vehicle data recording instrumentation and the ability to turn the PIE on and off remotely from the cab.


Ambient temp; 40 deg. F.

Subject vehicle; 2005 Chevrolet Colorado, 4WD, Crew Cab

Power Source; 12v lead acid battery

Connection; Alligator clip wires direct from motor to battery

Mounting; Fastened to a wood pallet in truck bed, pushing on front of bed, tied down with strap

Direction of Travel; Predominantly North/South with up to 3.5 miles of East/West

Terrain: Paved highways with some hills with grades up to 5% & one gravel lane-way approx. 1000’ long

Speed: City speeds/traffic 0-30 mph, Suburban 40 mph, Rural 45 to 55 mph

Total distance traveled: 13.2 miles


Observations were as follows:

Discernible pulsing/surging in the forward direction at ALL speeds (0 to 60mph)

Noise much louder when stopped but lessening with vehicle speed

Not very discernible during normal to hard acceleration

Very noticeable during “coast down”, coming to a stop and under gentle acceleration


A good analogy would be someone pushing the vehicle with one foot (like a skateboarder) from behind using just one hand on the vehicle.


The Set Up:

Vehicle mounting was kept as simple as possible, yet safety was always a very real concern.

The PIE was very simply screwed to a wooden pallet with deck screws. The pallet was modified to fit the truck bed of my subject vehicle properly.

Braces were placed at the front of the pallet so that the forward push is placed on the front of the bed (under the toolbox) and a strap was placed at the rear to keep the PIE/pallet assembly from lifting or shifting (sliding is not a big concern as the bet has a rubberized liner).

A simple 3-sided plywood box covering was made to keep debris and weather from directly affecting the PIE (good thing I did this, since we just had a freak May snowstorm) but the ends were left open for access & visibility (imagine the questions a police officer might have otherwise).

May 9, 2020, Prepping for Road Testing

Preparations are under way to be ready and able to perform the next phase of operations, which is road testing. Since this will be tested in an open-air pick-up truck bed, several issues come to mind.
First, unattended operation. Nobody will be in the back with it due to state laws prohibiting riding in the back of a truck. If timing does slip, or there is a mechanical failure there will be a significant time lag between the failure point and human intervention. (Note: Most testing facilities also prohibit open-air riders without expensive safety harnesses and specialized equipment)
Second, the weather. The PIE needs to have some protection from inclement weather and from any debris that the wind could potentially deposit in the open gear mechanics of the PIE.
Third, nosy people. This is potentially the trickiest part of the testing. At this early stage of testing, a bit of privacy would be advantageous. The public is invited to view the data, pictures & videos online. Eventually there will be public demonstrations.

Secure vehicle mounting, with a weather resistant cover (hood).
Remote switching control, I prefer hard wiring for reliability.
Video monitoring, it would be good to keep an eye on the PIE if possible.
Graphic monitoring of engine load, done via vehicle computer interface.
PIE timing adjustments made & verified.
Tensioner spring tightened. Additional belt support may be necessary if there is a problem.


Moving the PIE & all its fixings back and forth numerous times, I can say that it most definitely wasn’t built with weight limitations in mind. That’s a polite way of saying that it’s freakin’ heavy.
I got out my digital AC scale & weighed the PIE, battery & axles just to get an Idea of the heft of the components.
Weight of the current PIE is 46.46 lbs., not including battery or rolling axles.
Weight of pair of axles used is 3.640 lbs., these won’t be needed for road testing.
Weight of battery used is 27.005 lbs., a battery is needed for “plug in hybrid” status.

I am B.
I am a professional Auto Tech with more than 35 years in the automotive mechanical industry. I am currently a garage manager responsible for the maintenance & repair of more than 20 vehicles in the Northeastern U.S. “Rust Belt” and I am looking forward to retirement.
I can be a grumpy old fart with little patience for closed-mindedness, so no apologies are offered if I offend anyone by being myself.
I am also an ASE certified Master Auto Technician, hold a Bachelor’s Degree in Automotive & Transportation Technologies and have earned many automotive, truck, bus & business certifications.
In short, I know how things work.
I am making this blog to make public the development & usage of this truly revolutionary technology that is capable of making almost any vehicle into an electric hybrid.
I am only one of many people building & testing this, and similar, tech worldwide. There are multiple designs which have been proven to work and this is only going to really discuss the one “originated” by Brandson Roy Thornson, and reworked by me personally.
This is a Closed-Loop Reactionless Impulse Propulsion system, and, yes it does actually work.
I expect:
Plenty of scoffing.
Accusations of making fraudulent claims.
Backlash from people who would rather not see this tech go mainstream.
Again, I am a grumpy old fart, so if anyone takes issue with my work it really doesn’t matter.
There are many well informed, educated, brilliant individuals who state unequivocally that his technology is nothing more than a pipe dream and/or pure bunk.
If you want to “blast” this content, I respectfully ask that you keep an open mind, be civil, and email me privately. I have neither the time or the patience to discuss this with anyone who just wishes to cause disruptions.
This is not a new technology, and although it has been demonstrated many times, there are those who close off their minds and refuse to entertain ideas which do not always fit into nice neat little packages.
Along with other fellow technicians, engineers and mechanics scattered around the globe, I am going ahead with revealing this tech at my own expense as a fully Open Source Project.
I have been writing this blog privately since the inception of this project and I think it is about time that I make it public.
I will be editing and then copying/pasting my original documentation here.
More will come as time allows.
Thanks for visiting & I truly encourage everyone to experiment with this tech.
A Note to all open-minded Mechanics & Experimenters,
(Added 4/10/2020)
This informal document’s purpose is providing information regarding a privately funded & produced project to build & test the feasibility of a reactionless propulsion system to be used in the transportation industry as a hybrid drive system that can be added to existing vehicles of multiple types. The electrically driven propulsion system I am outlining here is based on the Thornson EZKL Drive invented and partially developed by Brandson Roy Thornson. This and similar Thornson-like drives have been functionally proven, independently tested, and I can personally attest that there is no trickery involved.
While there are other types of potentially effective designs, this is intended to outline this functional Thornson-like Pulsed Linear Motion Generator and promote the dissemination of this information by promoting a Grassroots Mechanic Movement. This Technology needs to be developed and used without being restricted by any entity or entities who would see this monopolized or suppressed.
It has been vehemently opposed by the mainstream scientific community who are not willing to review and reinterpret the widely held concepts of movement conservation even when demonstrated via working machinery.
People who have invented, promoted or attempted to market similar tech have been stopped. Some were discredited through manipulation of public information, others were blacklisted – even after their device(s) were reproduced and tested by mainstream institutions (SUNY Buffalo, etc.).
This is the reasoning regarding the need to get this information to experimenters, and hobbyists through a grassroots type movement.
This tech is very reproducible at a reasonably low cost. It was built utilizing many recycled & re-purposed components. It is also very understandable to the mechanically inclined without any specialized training or the need for any advanced mathematics.
Review this data & please reproduce this tech for yourself.
Build it, use it, and show others how to build it.
That is the core of the Grassroots Mechanic Movement!
P.S. PLEASE ALSO NOTE: The construction techniques & methods along with the parts & materials used are not intended to comprise a finished device but are only used for prototyping. Welds are little more than tack welds, used components are used whenever possible & most parts are intended to be easily disassembled to make changes. That is exactly why unit(s) depicted here appear crude and cobbled together, but great care has been taken to ensure accuracy & safety while maintaining this as a low budget project.
