PIE 4.8 – The APEC 5/1/2021 Conference and the “Inertial Doppler Effect”

The PIE 4.8 CCW wheel is pretty well set. I have attempted to get some force tests done with a force meter, the output readings were very unstable at best. I was however able to get some slightly better readings with an accelerometer.

The photos are screenshots from an accelerometer app on an android phone. The waveform or trace is below the “0” when pulling forward. It is obvious that there is a more stable pull during each pulse forward, and disorganized spikes in the reversion direction. Keep in mind that it will show a small reverse pull between forward pulses just because the chassis slows slightly between propulsive pulses.

On Saturday 5/1/2021 I had the honor of being asked (at the very last minute) to speak about the PIE systems on the APEC conference Zoom meeting. My part was near the end but just before open discussion at 4:51:28 and even though I did not have anything prepared it was still a lot of fun. APEC is Advanced Propulsion Engineering Conference and it is hosted by Tim Ventura of American Antigravity (https://www.americanantigravity.com). The full video of that conference is here:

During the conference we talked about the PIE systems, discussed theory, and talked about the near-future testing. We also discussed a phenomena that has been showing up in PIE experiments since the first on-road tests of the PIE 1.0. The phenomenon is that of increasing thrust when the entire unit is in motion. The faster the test vehicle moved the more forward thrust was experienced with each pulse. This has also been experienced and proven in the lab, so it has moved from a possibility into a fully testable repeating phenomenon. For lack of any better analogous terminology I started calling this the “Inertial Doppler Effect”. As a friend and colleague was maintaining that he thought the PIEs are still some form of “stick-slip” drive which depend on friction to operate (fully disproven in the lab) and it occurred to me that maybe he is wrong and right at the same time.

This is my current understanding of this phenomenon. I know that my “loose definition” of Doppler is not 100% correct when comparing a mechanical system to an EM wave form. This is a copy and paste of my reply to the idea of the PIE being a stick-slip drive:

My analogy of inertial Doppler is a “still forming” theorem, bit it currently a spacial/mass/inertial interaction which is proving itself in reality. Here are some cold, hard, facts… Doppler effect exists because the “center of mass” of the energy wave is moving and the energy is emanating from that “center of mass” making the wave have more “force” in the forward moving direction (Overly Simplified). Sooooo… The PIE (or I venture to say “any”) inertial drive will exhibit the Doppler effect, and if that is so (it is IMO) then all inertial drives ABSOLUTELY MUST have more mass in the overall structure than the masses being displaced (moved, oscillated, etc. also) in order to have directed thrust (linear motion). If the mass of the structure were less there would only be massive vibration (oscillation) – example: if a 2 moving mass (weights) structure weighed 5kg and the masses weighed 2.5kg each there would be a net linear propulsion of little more than zero even if the propulsive force was 2X higher than reversion force, but if the structure weighed 10kg there would be more mass “in motion” than there is “reverting”… So, ideally the mass of the structure should be 1 to 2X of the reversion force!

If I didn’t ramble too incoherently, and you are following my train of thought above, this means that ANY inertial drive which succumbs to this theory is a “stick-slip” drive but it is the inertia of the structure’s mass that it’s “sticking” to (pushing against). It also explains the Doppler effect because if it is “pushing” against inertia itself, that inertia is stronger as the structure moves!

I may have sprained a brain cell or two trying to put this theorem into words!!!

Till next time….

PIE 4.7 is now the PIE 4.8 with Thrust Test Video

The PIE counterclockwise wheel (CCW) is nearly finished and will be tested very soon. I made a significant change to the “outer stop” which works so well to warrant changing up the model number to PIE 4.8 and I am installing them on all of the planet gears for the PIE 4.8.

improved outer stops and “Halo” mounts after painting

Halo mount and improved outer stop as seen during setup

I have also improved the mounting (resembling a halo) for the swinging weight. This improvement also allows for the addition of strengthener braces if it is found to be necessary.

Halo Bracket for Swinging Weight

The new stops allow for actual adjustment of the stops. This will allow me to make small changes to stop position and find out if there is a particular “sweet spot” for the outer stop.

Improved outer stop and halo mount working well during SDC setup

The CCW wheel is constructed to run on its own with its own separate motor and speed controller (as seen above). This is necessary to run the full gamut of necessary tests regarding phasing and RPMs. Once these tests are complete there will be better data regarding proper synchronization and whether the two opposing wheels should even be synched at all.

I have posted several videos on my YouTube and BitChute channels showing the building of the CCW and the new PIE 4.8 stops. Here (below) is the new PIE 4.8 CCW running its bench test with the SDC installed.

Here (below) is the first bench test run of the CCW before the SDC was installed.

Here (below) is the PIE 4.8 CCW set on some pipe rollers just to check for backward force (reversion) vs. forward force (thrust).

PIE 4.7 – Now with Two Weights and Actuators, PIETECH P. 15

A second weight has now been put together for the PIE 4.7. It is .02kg heavier than the first weight, but that can be corrected (if necessary) by drilling shallow holes in the weight until corrected. The weight of each is 2kg +/-.

PIE 4.7 with Dual Weights and Actuators

Two SDC actuators are installed. They are each 8 inches long and are attached to the main wheel’s outer ring gear with ¼” beam clamps from the local hardware store.

New Controls

Additionally, the SDC potentiometer “pot” is installed next to the main speed control pot on the motor speed controller, a mini toggle switch was added to turn on or off the SDC function, and finally a main-power toggle switch was added between the battery and speed controller.

Bench testing is showing a most definite power output increase across the board when the SDC is on compared to tests without it. It seems that because of the improvements made, the PIE 4.7 (with its one wheel and two weights) is comparable to the PIE 2.1 which is twice its size. Proper testing will be done in the next week or so, then we will know for sure.

Fastened to the Bench & Back to Simple Chain Drive

A video is posted to both the YouTube and BitChute channels giving a quick tour of the PIE 4.7 and then a demo with it firmly attached to the bench.

Disassembled/Reassembled PIE 4.7 – Dual Actuator First Bench Test

Revisiting and Updating the PIE 2.0 into a PIE 2.1, PIETECH P. 14

Because the PIE 2.0 was shelved without any disassembly and was kept in-tact from its last tests and demos, I decided it would be interesting to install the 24-volt electric motor and speed controller on it. It was really great to see the PIE 2.0 spring to life with a renewed vigor thanks to the powerful motor. But this was not the reason for upgrading the version number…

Motor Swapped on the PIE 2.0

Since the motor and speed controller was working so well (on 12v) it seemed natural to add the speed differential control (SDC) to it as well. I started with one actuator, so the PIE would get a speed boost for one half of the rotation which uses two weight pulses per revolution. This would tell me immediately several things. It would indicate if the SDC would be effective on another PIE (repeatability test) and if it would still work with an opposing weight approaching and entering the “neutral/reset” position.

SDC Installed – The PIE 2.1 is Born

Both results were 100% conclusive that the result was a definite increase in power output!

Next was to add a second actuator so the boost would be working with each half of the rotation. A second actuator of identical length (8 inches long) was installed 180 degrees away from the first actuator. Power output seemed very high but because I don’t have a force meter, I simply was not certain. The simple answer was to add a toggle switch in line with the SDC circuit to simply turn the SDC on or off while running the PIE.

PIE 2.1 – With Dual Activators

Results of the dual actuator test was amazing! The base speed could be run from 0 to over 100 RPMs, and the action was the same as it was when running on the drill motor. At different speeds ranging from approximately 30 to 100 RPMs, the differential circuit was activated and deactivated at many different base speeds with very powerful results. Judging only by the amount the PIE was moving the bench I would estimate an approximate 50-75% power increase with the SDC active! THIS is the reason I am calling for the version increase from 2.0 to 2.1 on the older PIE.

As a side-note, the PIE 2.1 runs “smoother” with the SDC, and will probably last longer too!

It is now time to “ramp up” the experimental PIE 4.7 with a second weight, and maybe increasing the mass of the weight(s) to around 2kg. In order to do this mass increase, each weight will be using slightly more than 16 linear inches of 3/8”X2” steel along with the BBs, bushing, bolts and weight mounted guide.

New Dead Blow Weight In Process – Empty Cavity To Be Partially Filled With Steel Shot

As the PIE becomes more “refined”, the total monetary cost of each build increases along with the increase in output power, but when overall quality increases the cost will invariably increase as well.

Videos of the PIE 2.0 changing into a version 2.1 are available on my YouTube channel now, and will also be on BitChute very soon.

PIETECH Page 11, PIE 4.6 Eccentric Drive Gearing

12/23/20 PIETECH Page 11, PIE 4.6 Eccentric Drive Gearing

I was going to be putting my effort into duplicating the dead blow weight so that I can test the first wheel with 2 weights, and I can build a second wheel to go with the first one. However, when I was doing the propulsion testing with the single wheel, I noticed that as by battery started running down propulsion was diminishing. This was found to be a “slow-down” of the motor during the critical “power-stroke” (those who have read my manual know what that means) causing propulsion loss. To compensate, I manually turned the knob on the speed controller during slow speed operation. Naturally, I did not meet the correct RPM every time, but I noticed that if I overshot the running RPM at exactly the right moment, the PIE 4.6 would lurch forward much stronger.

A friend of mine, who also has been working on his own inertial propulsion drive (YouTube Channel) and I were discussing this. It has been found that changing the time base in mid or quarter turns of the main wheel could enhance the propulsion effect dramatically.

My choices for this concept are to either electrically change the RPMs back and forth or use eccentric gearing to smoothly transition the RPMs thus changing the time base. In the end I may try them both or perhaps someone could find a better method.

For now, I have started this experiment with the eccentric gear setup. Eccentric gears are essentially a pair (or more) of identical gears or sprockets, with their axle’s not on center in the exact same amount. Since each will “wobble” exactly the same amount, they can be meshed together. When one it rotated at a steady RPM by an outside source (electric motor, etc.) the other one accelerates through half of its rotation and decelerates through the other half.

Eccentric Gear (Sprocket) Set

So, for my experiment I have 2 identical sprockets, each mounted on-center and each on a bearing. Then there are two more identical sprockets fastened parallel with the first ones, each mounted exactly the same amount off-center. The two off-center (or eccentric) sprockets are timed and connected together with roller chain.

Sprocket set 1 is driven by the electric motor. Sprocket set 2 is connected to the PIE 4.6 wheel. As the motor turns at a steady RPM, the PIE 4.6 is accelerating and decelerating constantly. This is timed to start the acceleration approximately halfway through the portion of the cycle when the weight is in contact with the center (inner stop) axle. Timing here is very important and even a few teeth off on the sprocket to wheel timing makes a huge difference. In fact, it has been observed that with the timing off too much, the unit would oscillate forward AND back with significant force.


Eccentric Drive Ready For Testing (Timing Was Not Correct In Picture)

I know that this design will not be well suited to having multiple weights on the wheel, but I do have a goal in mind that I am not ready to introduce just yet. If this idea works out, it would be capable of enhancing the operation of any of the PIE versions.

The downside is; if I only have 1 weight per wheel the RPM is limited due to transverse (sideways) forces threatening to tear it apart.

PIETECH Page 9 – PIE 4.5 With New Dead Blow Type Weight

The latest test of the PIE 4.5 is using a 1 kg dead blow type weight. The weight is a steel box with steel shot (BB’s) inside it. It appears to have a lot of promise, as there is virtually no “bounce” when the weight hits the inner stop, and it seems to be dampened where it would contact the outer stop if it had one (has not been installed).

PIE 4.5 with Dead Blow
Dead Blow Weight Installed On PIE 4.5

There is a video of this first testing on YouTube and BitChute. The problem however remained that the centrifugal force and impact force did not push in the same direction, which was the reason for Thornson’s “Inner Planet Trap” which would hold the weight and release at the correct time.

The answer is to install a “guide” on the end of the weight which would keep the weight near the center axle and correct the problem of thrusting in two different directions. This is proving , so far, to be a much improved design. This can also be seen on YouTube and BitChute.

Guide Fastened to Dead Blow Weight

These improvements are now bringing the PIE version up to “PIE 4.6”.

PIE 4.5 and My Original Thornson Drive Replication

Hi everyone and welcome to my blog’s new home. I hope that this venue will be of at least the same quality as before, and I really hope that the text is a bit easier to read!

I posted a video on YouTube & BitChute of the PIE 4.5 with 3 gears, 2 gears and just one planet gear on it. There is a bit of controversy as to which is better and what configuration should be considered for the PIE 4.5 to continue. Watch the video and you can plainly see the lack of propulsion with better balance (3 planet gears), and much better propulsion with a fully unbalanced wheel (1 planet gear). Of course, getting rid of the jerking nature of the drive is a primary goal along with stronger propulsive force.

I have gone back and reviewed my recorded data, and videos, going all the way back to the very first truly functioning drive still being referred to as a Thornson Drive even though the stop modifications were already being changed and modified to the design finally used in the PIE system. The wheels (4 of them) all had a single planet gear, they were all running more or less in-sync, and it just plain worked. I am going to put the 3 videos I have of this original unit together into one video and post in soon.

Keeping this in mind, and knowing that I really can get a MUCH stronger forward pulse without increasing the back pulse, the goal remains to pulse smoothly (an oxymoron). For this plan to work, I need 2 or more complete PIE units that produce fairly equal amounts of force and that can run in-sync (with a calculated offset) without actually being physically mounted to the same frame.

Stay tuned to this blog and my video channels as I think some exciting things should be happening soon!
