The Origins of the Trammel Engine and Recent Activity Update:


Happy Easter!

Although work has slowed a bit progress continues, and here is a synopsis of recent activity:

1- The Trammel engine got a new (more powerful) motor with speed controller.

2- Trammel displayed thrust only during acceleration with new motor.

2- LOLA or Linear Oscillation Linear Thrust experiments began.

3- Linear component analysis showed it is useless without proper energy storage and release.

4- LOLA v.1 is a linear drive experiment where dual linear components rotate parallel with the axle.

5- LOLA v.2 is a linear drive experiment where a single linear component oscillates which also builds and releases energy by building spring tension and releasing it as the mechanism rotates “over center”.

6- Both LOLA experiments allowed some better understanding of the movement of energy between the mechanism and “etheric inertia” which creates propulsion.

7- The term “etheric inertia” was coined by me. It is the inertia which is not part of the machinery itself, but instead is the inertia which is manipulated and is observed as the movement of the drive and is usually expressed with terminology such as “inertial thrust”. Where thrust would be the verb and/or adverb, “etheric inertia” or EI would be the noun and/or pronoun defining the “environmental force” not just the action of that environmental force.

Note: Inertial Doppler was also coined by me as the observable increase in thrust which happens as the vehicle using the inertial thrust engines move faster, mimicking a type of Doppler effect.

8- During recent APEC conferences which included presentations by Ross Small, myself, and others, it has been mentioned that the RBI machine of Ross’ an my PIE X/Trammel Engine are derived from the work of Mike Marsden who was the inventor of the Mac-Quan. Mr. Marsden dropped out of sight before the unveiling of his second-generation Mac-Quan which was set to occur at the annual Wright brother’s celebration in Kitty Hawk, NC around 2011 or 2012. The Mac-Quan has long been the “gold standard” that all inertial propulsion developers have hoped to duplicate. Mr. Marsden was rumored to have passed away, but I believe he has retired and is now living in relative seclusion somewhere in North America, no longer having anything to do with the technology. The reason(s) is/are up for speculation as he never actually said why he closed up all of his businesses in Texas and dropped out of sight. Even his old web site ( is missing from resources such as the Wayback Machine.

I have been fortunate enough to have made the acquaintance of some people who knew Mike Marsden firsthand. Although he did not “give away” the full secret of the internal mechanisms, he did guide these people toward the correct answers. Their information and engineering skills combined with my mechanical background and “get it done” work ethic has produced the PIE X or Trammel Engine as I like to call it.

I have agreed to not divulge the inner workings publicly in return for the engineering data. Hopefully in time the design will be perfected and surpassed at which point it will be part of textbooks around the world.

If anyone here has ever been in contact with Mike Marsden, knows anyone who has been in contact with him, or knows anything about this technology, I would love to hear from you. I will gladly keep any information anonymous and secure and not share anything without your express approval. Email me at


Testing rotation speed with a sensor and lab scope setup is now showing that the assembly built to eliminate backfire is keeping the internal speed change reaction times to be too slow to provide proper output thrust. Internal components will now be modified, probably using a pair of timing chains instead of cam-like lever assemblies.

Personal note: I truly long for the day where this is fully functional, and we can have open discussions regarding the design and inner workings of the Trammel Engine. Maybe I should be creating a Power Point presentation as I go…

Trammel Testing, APEC, PIE Mini

It has been MONTHS since I updated here… A lot has happened in my life and in the shop! For those interested, I have switched gears in my professional life. Since the change is quite dramatic, I have been under some stress “getting in the groove”, but it is a needed change and I’m getting it all figured out.

The PIE X aka Trammel Engine is coming along. Inside it (still not ready to reveal too many details) are some components which were made too weak, but they have been rebuilt and replaced with much more robust pieces! I have experienced some intermittent thrust and have kept moving forward with this as much as possible. I also recently received a much-improved motor and speed controller which is now installed.

A Look at the New Motor
First Run Test

It has become quite evident that as I contact potential business partners and investors, I need a small and lightweight demonstration model which can be taken along to those meetings. With that in mind, I introduce the “PIE Mini”. The PIE Mini is a nearly complete, single weight, working, demo model which is really small and light with plastic gears and a hollow tube instead of a large “wheel”. It’s power source is a super cheap cordless screwdriver from Harbor Freight. Although it is intended to be a portable demonstration device.

I believe it will also be a design which could become the first model of a sellable working model for science minded people everywhere to experiment with.

There are a couple of videos of the PIE Mini on BitChute .

First Test on Wheels

I have also now run a live demo of the Mini at the APEC conference on Feb. 27, 2022. During this presentation I showed that the unit actually needs mass to operate and that is really it’s only environmental prerequisite. I should be posting that presentation on my BitChute and YouTube channels very soon. Until then, here is a link to it on the American Antigravity YouTube channel.

Part 2

I want to thank Ross Small for joining the video conference with a presentation of his own. He is building a “linear thrust” machine in the hopes that it will be a helpful learning aid for everyone to better understand the mechanism of inertial propulsion. Some of those very principals are integral to the Trammel Engine, and have also got me thinking about other, future, design builds.

PIE X Gets a New Name – “The Trammel Engine”

November was a very busy month for Stclairtech R&D, and for the PIE X project!  

Ready For “Public” Testing

So much has been accomplished with the PIE X project it is mind boggling!!! The “backfire” issue has been resolved and there have been some very successful tests completed running with the electric motor.

Some of the highlights are:

The “backfire” problem is now well controlled with a minor design workaround. Future builds will take these backfire control requirements into account so that “workarounds” will be unnecessary.

The PIE X has earned itself a name of its own and is now known as the “Trammel Engine”. It is a name which is both literal and figurative. Literal because it has internals which resemble the operation of an ellipsograph, or “Trammel of Archimedes”, and is a figurative tongue-in-cheek reference to the same machine’s moniker of being a “do-nothing machine” since its purpose seemed nonsensical for the most part.

 The Trammel Engine (T-Engine or TE for short) is now running well enough to perform some rudimentary testing which has demonstrated true linear thrust. It has been measured thrusting upward with a weight scale with an averaged thrust of .7 lbs. and peaks ten-times that amount running at input speeds of no more than 350 RPM.

Unlike the earlier PIE systems based on Thornson technology the T-Engine does not seem to have a low-speed limitation, and it is creating more thrust as RPMs increase.

A few shareable facts (so far):

1- The TE has externally driven mechanical components which are driven via the electric motor(s) and cause overall rotation along with internal rotating components.

2- There are 3 major rotating component assemblies consisting of metal parts using ball-bearings for friction reduction.

3- Some of the pieces of the internal assemblies can be labeled with names resembling those of internal combustion engines. Pistons, connecting rods, camshaft-like parts, and flywheels are just some of those named components.

Overly simplistically stated, it uses something very similar in function to a lever pulling a load which is allowed to move past apex and “snap over center”. This over center, snapping, rotating assembly is moving masses, accelerating, decelerating, and recovering them 4 times per disc rotation.

The internal timing of these components, and the use of a “camshaft-like” sub-assembly is of utmost importance to eliminating the backfire issue!

There are several videos available on YouTube and BitChute, the latest of them (at this writing) is a 2-part set called “Trammel Engine Works Part 1” and “…Part 2”. Part one shows the test rig, and part two shows a “successful” test which ended abruptly when the fuse blew. It turned out that the fuse blew because one of the “connecting rods” broke. Here are those videos below.

Part 1
Part 2

The broken and damaged parts are now being replaced and repaired, there will be more tests to come very soon! And hopefully more can be revealed soon…
