Vol 2, Page 9, Testing the PIE 2.0, and My Patience

Well it works, but as with any new design there are issues. I have put around 19 miles on it and it really does seem to work well, when it will keep running.

First and foremost is the locking up problem. The little springs did a reasonably good job of stopping the lockup on start-up, unless I started it at a bit of a higher speed. High speed start-up would overpower the springs and locking was still an issue. Then came the locking problem while driving. Every time I might hit a bump, or tap the brakes, it would lock up. So, I took the weights off, cut the metal tab off for the outer stops, and welded stops onto the planet gears. One corner of each weight then had to be trimmed so it would not hit the new stops and viola, no more locking. I did get one of the stops a bit crooked, but I will fix that next week.

Second was the drill motor kept cutting out. Apparently, there is a bad spot in the variable speed trigger, and (of course) I found it. With the new stops came a bit of a smoother run at higher speeds, so I upped the speed and the motor no longer stopped randomly… Until the fuse blew… Replaced fuse with circuit breaker and then the chuck loosened up on the chain drive shaft…

The PIE did lock up one more time, because of the crooked outer stop (that I WILL be fixing next week) the weight hit it hard enough to slip past it and lock on the back side. Reset and speed reduced slightly it seems to have worked fine on the last trip around the block, although there is a definite speed to power correlation. More speed=more power!

Once testing on this model is complete, a high-speed unit is definitely on the drawing board!

 I do have to wonder why… Why it is that when testing on public streets and roads it seems that every bad driver within miles is attracted to the test vehicle?!?!? Getting tailgated, cut-off, swerved at, nearly t-boned, and behind extremely slow drivers happens every time. I sure am glad it’s Friday!!!

Vol 2, Page 8, The PIE 2.0 is Ready for Testing

The PIE 2.0 is basically ready for real world testing. The PIE is fastened to a pallet and is being driven by the cordless drill used to test it. I made a bracket for the drill and “gutted” an inoperative battery pack so I could connect wires easily. This allows me to power it from the vehicle’s electrical system or a 12V battery so that a simple on/off control is accessible to the driver.

PIE 2.0 Ready to come off Work Bench


The Power for the PIE 2.0, and the Bracket for the Drill

I do still need a weather cover as it will be tested in the same pickup truck as the PIE 1.0 was, but that is the simple part of the whole project.

I will be posting all findings here on the blog and also on MeWe (www.mewe.com/i/bryanstclair).

I want to reaffirm the intent of the Grassroots Mechanic Movement (GMM) to freely distribute and promote the “reactionless” propulsion technology of the Pulsed Inertial Engine (PIE). I do not advertise the Grassroots Mechanic Movement, and I do not charge anything for the full disclosure information published either here or on the blog. I also do not have any monetization (at this time) of my videos or the blog. The videos are available on YouTube as well as Bitchute and I find it rather interesting that there are a lot more views on Bitchute.

I encourage mechanics, tinkerers, technicians, and anyone who is curious to build one of these and PLEASE post the results.

Too many people who made public statements and videos about this tech claimed it was not workable, but they also did not follow ALL of the original instructions laid out by the original inventor, Brandson “Roy” Thornson. The important internal “trigger” mechanisms were not built and installed, so the “replications” weren’t really replicas at all.

Check my videos, actually read my blog, download the shared files listed within the blog, visit MeWe, and then go to your workshop and build one for yourself. I have laid out the build to be as inexpensive as possible utilizing many used parts from the auto recycling yards, scrap metal pieces and even custom building the gears without a machine shop.

In less than 1 weekend of puttering around the garage (like many of us do) any hobbyist, or home mechanic, with a grinder and a welder can have a single wheel with 1 weight working and proving that this technology works.

Vol. 2 Page 7, PIE 2.0 Major Update,

Building Upward & Using Torsion Springs

I have repeatedly said that I would make this project 100% open source, I am keeping my word and even though I don’t have it ready to run yet, I am posting a reasonably major update now.

I have not posted any real updates as to the status of the PIE 2.0 build in the last few days, so here is what I’m up to.

The PIE 2.0 is progressing very well so far. I had a problem with the weights “jamming” on start up because I am using the planet gear axles as the outer stops. This seems to be alleviated by using very weak torsion springs to push the weights out of the position that jams the rotation. The springs add very little to the force of the weights swinging outward and should pose no significant change to operation. I will include more info about the springs if anyone requests it, and if there is someone following this who is also building a PIE 2.0, I can get these springs for you if you let me know.

The significant portion of this update however, is the addition of a second wheel. Instead of adding it next to the first one, the new wheel is mounting ABOVE the first (or primary drive) wheel. The phasing of this upper wheel is designed to be at 90 degrees. This gives the PIE 2.0 4 pulses per revolution and should be a very significant improvement over the PIE 1.0’s single pulse per rev.

Double Decker and First Trial With Torsion Spring
Three Weights With Torsion Springs on New Double Decker Design

 This significant change is an integral part of the now modular nature of the PIE 2.0 and “should” be a design that can be expanded in time. It also gives the PIE 2.0 a much smaller footprint, this will allow it to be installed and used effectively in much more confined areas.

This modular design could also be further developed with a logic controller and individual stepper motors controlling each wheel. That would allow non-linear build designs that can be suited to custom applications.

With this new “double-decker” design, I am also enhancing the framework so that (hopefully) testing can be completed without the unit breaking itself too badly under load. Remember that this is still a prototype and prototypes are built to reveal flaws and weaknesses as well as being a testable model.

Vol 2, Page 6, The PIE 2.0 Is Coming Together

The PIE 2.0 build continues as the new chain drive works very well and the unit is now being assembled on its own base so that it will be mobile. It is a notable observation that the PIE 2.0 pulled the work bench out of place on multiple occasions during individual component testing.

Bench Testing

It is easy to see the rpm variation potential now that slip is eliminated between the drill and the PIE’s wheel. For testing purposes, I have braced the drill with a piece of metal so it wouldn’t keep pulling it back and causing speed variations since I was not holding it steady enough.

As I continue the build, I still have not decided on a motor to power it. I do not want to commit to any particular motor design or speed, before doing some initial testing. There is still more work to do before I get to that point, at which time I will post those results here as well.

I am certain of is that if the PIE 2.0 becomes much more powerful, the whole unit will need a redesign so that it does not tear itself apart!!

I am also considering installing some very light weight springs to keep the weights from folding inward when it is not running. When that happens, the assembly can jam and not turn, it is as close to a “backfire” as the PIE 2.0 can have. The springs need to weak enough not to affect operation, but strong enough to do the job. I made it work with rubber bands, but they certainly won’t last long. It is something to think about.

Addendum 6/11/2020: As I was thinking about the possibility of adding some sort of spring (rubber bands work well) I noticed a spring clamp in my toolbox. EUREKA!! That is most likely the answer, a torsion spring! Like a mouse trap spring, the torsion type spring might be exactly what I need to keep it from “stalling on startup” without applying enough force to change how the PIE 2.0 works!!!

Vol 2, Page 5, Sprockets & Roller Chain Drive

Bench Testing Chain Drive with Drill as Power Source

I finally got my sprockets for the chain drive! They are surplus so there are nicks and dings, but nothing a file won’t easily fix. They have an “unfinished” one-inch (25 mm) hole, that puts the hole slightly undersized, but that actually worked out in my favor for use on the jack shaft as it made for a nice press fit on the 1” section of shaft. I then welded the sprocket into place on the shaft to make it a permanent install.

I used a plasma cutter to open the 1” holes up on the sprockets being used on the wheels, that way there is no need for spacers to mount them on the axles. Cutting the hole open like that is ugly, but I don’t really care, as it cannot be seen once it is installed.

I put it together enough to see the chain drive work with a cordless drill running it up to approximately 1500 RPMs. I still need the parts bolted to the plank base so that nothing can shift position with the weights installed.

I believe that I will wait to finish the drive assembly with a motor until I can see how much power it is going to take to make it run, and at what RPM. I have several large electric drills that I can use to do those tests if necessary.

Dual Weights
(Maybe I’ll take a pic without all of my workbench clutter in the background someday)

Two days ago, as I was finishing up for the day, I decided to put both new weights on a single flexplate assembly at the same time. I really did this as a way to see the action and make observations of any interference between them. I was pleasantly surprised when the interaction appeared to be complimentary in nature.

I was so pleased with the interaction that I decided to “spin” it up with the cordless drill. The amount of power being transmitted to the bench was remarkable, and because the flexplate was “balanced” out with the second planet assembly, I was able to run it at a somewhat higher speed without further modification.

I observed the weights each contacting a stop (one inner, one outer) at virtually the same time and producing complimentary pulses. I was so pleased that I immediately cobbled together a way to hold my phone and video this (the video is below and on YouTube).

Powered Dual Weight Bench Test

Now I am getting ready to put the chain drive on it, although I am no longer sure it is necessary to have a positive non-slip drive. I am including some pictures of the jackshaft being made at a local home-garage machine shop. I didn’t have any keyways cut into it, but I can always take it back for that if necessary. The dimensions are ½” up to 17mm up to 1” and back down to 17mm.

Cost was negligible for this because I supplied the metal to a home machine shop (along with beer) on a Saturday. Normal cost for this at a local machine shop would have been around 35 to 45 USD according to a couple of calls made, but many machinists would do this on their lunch hour at work for about $20.



Jackshaft in Lathe & Finished

The plan is to weld a sprocket onto the 1” diameter section of the shaft, then bearings will be mounted on the 17mm sections and then the ½” diameter end will be used for the electric motor’s connection.

According to the surplus company I ordered the sprockets from, I should have them in about 3 days…

Vol. 2, Page 3, Preparing Parts for PIE 2.0, Second New Weight -Build and Test-

Newest Weight Ready for Testing

Building the revised PIE, version 2.0, is well under way. There are two weights are virtually ready for testing. The gears are looking as good as they ever will, and the base has been partially modified to accommodate the revisions in the configuration.

I have decided that the drive system will be using #40 roller chain & sprockets. The sprockets and chain are available at a very reasonable price from surplussupply.com. It is too bad that they do not have spur gears to use for the sun & planet gears as well. Regardless, I am getting as much done as feasible while I wait for the sprockets arrive (I already have chain).

 I am planning to use a jackshaft, of sorts, to drive the chain. The inexpensive and plentiful components already sourced and obtained will comprise a portion of the jackshaft assembly. I am having a custom shaft machined upon which to fasten the sprocket.

A custom shaft would be unnecessary if the shaft, sprocket and available bearings were all the same diameter, but weighing the option of sourcing more components vs. those already obtained and having one custom component made I choose the latter. A local machine shop would make the shaft for between $25 and $50 US, while pillow block bearings would be that price for each one. As previously stated, the objective is a simple, replicable drive, that is also safe and affordable.

V2, Page 2- PIE 2.0, Problem with Physics, To-Do List, and A Personal Note


The PIE 2.0 project has commenced.  As could be seen in the pictures contained in my last post, a new weight is being developed for PIE 2.0. I plan on using the same design for the planetary gear sets because I they are simple and robust. I was not sure about the flexplates, but since they are already prepared for the purpose, I will use them until a reason to change presents itself. Some parts are being reused (from the 4-wheel unit) and/or repurposed. There are still many questions to be answered and most of them need to be put on the work bench in order to find the answer.

We know that computer models and all the advanced trigonometric formulas in the world are useless unless there is a way to put them to work. The differences between types of drives can be discussed, compared & argued but the proof is in the workshop. Sooooooo… I need to make something PERFECTLY clear.

The fact is, this damn thing works!

Setting up for bench Testing

The Problem with Physics is that Some Science is Not Allowed:

Science is: The observation, identification, description, experimental investigation, and theoretical explanation of phenomena.

Physics is: The science of matter and energy and of interactions between the two.


Our currently taught physics does not allow for certain outcomes, and any drive system that does not push against anything for propulsion is one of those outcomes not being allowed for.

Along with physics departments worldwide, NASA currently discounts this type of tech as fantasy. Yet NASA is currently using reactionless propulsion to position/reposition satellites in Earth’s orbit.

Countless scientists have witnessed a very early version of this system operate with greater efficiency than wheel driven, jet, propeller, or rocket driven forms of propulsion, yet they turn right around and state unequivocally that it is impossible and absolutely cannot work…Ever! 

Many witnesses will deny that they ever saw, or that there ever was, a working demo.

People’s lives have been ruined because they built a working device and tried to sell it to big business and/or governments.

Science teachers worldwide are told that if they teach this as a possibility, they will be fired. The only way this can be included in a curriculum is by “proving” it doesn’t work.

It seems that the ONLY ALLOWABLE outcome has been negative or no.

Since this Grassroots project flies in the face of all of that, I continue to publish ALL information regarding the PIE system (1.0, 2.0 and future versions) and as stated earlier, the inconvenient fact is that this damn thing works!

I hesitate to say that I am working to change the paradigm, but it works and it is repeatable.

This knowledge NEEDS to go public, needs to be peer reviewed, and needs to be put to use helping people everywhere travel more efficiently.



PIE 2.0 To-Do List (Subject to Change of Course):

1- Set up outer stops for the new pendulum weights

2- Enhance bearings on all rotating assemblies (Doubles?)

3- Strengthen framework to withstand higher power output

4- Higher speed & strength motor

5- Synchronous drive system (Roller chain, T-belt?)

6- Consider “stacking” flexplates rather than side-by-side positioning to reduce footprint

7- Consider sourcing off-the-shelf parts for future versions, kits, etc.



A personal note:

As I am writing this, I want to thank everyone for watching my videos and reading my words.

I need to remind everyone following along that I am funding this completely out of my own pocket and then sharing it freely. I am not accepting donations nor am I selling anything for funding or profit.

There may be a saleable product in the future, however, ALL of the info in my personal journal & subsequent public blog are still going to be free as long as I have a say.

Perhaps, eventually, kits might be made available. I can imagine a kit to add hybrid capability to a vehicle for about the price of a go-kart.

 Right now, I want to share this with everyone, worldwide. I would hope others would see how simple this is to build a PIE as well.

Volume 2 (V2), Page 1, PIE 2.0 Begins

Volume 2 (PIE2.0)…

The rework of many unused parts that are left over from PIE1.0 has begun, along with some newly fabricated pieces for the new unit. Planning for this began about the same time that the first successful demo pulsed its way across multiple work benches.

From the time that first unit moved on its own I have wanted to build a better unit, capable of higher RPMs and running a heavier pendulum weight. Digressing to, and remembering, the 1970s VHS video of Brandson Roy Thornson’s drive pushing a canoe around an Olympic sized swimming pool, that unit had 4 rotating discs (2 CW rotation, 2 CCW rotation) and each had a 5-pound pendulum weight.

PIE 2.0 is going to start out with weights that are around 4.7-pounds. They will not be using any counter-rotating assemblies unless it is deemed absolutely necessary. Yet to be determined is to the number of rotating assemblies, the power source, and speed of rotation (RPMs).

I have about 20 to 25 pictures of various parts, pieces, tools & assorted “junk” waiting to be put to use. Since some find that interesting, I will put some of the pics in this the blog, but will not include them in my personal journal documenting this project.

Comments are encouraged, even if only to say that you were here.
Thoughts, notes, or suggestions are welcome. 

Some visitors will undoubtedly wish to tell me how foolish and impossible this is, please do not bother, as flaming and/or non-constructive criticism will not be well received here.
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.
