Censorship?

 Censorship?

Well now, after being reasonably ignored for quite some time now, apparently the PIETECH BUILDER’S MANUAL seems to have caught some unwanted attention. Out of sheer convenience, I decided to use the eBay platform as a service for interested people to purchase the manual. After being listed for just two weeks, the listing has suddenly “disappeared” completely from eBay and erased from their archives. After speaking with a genuine human being at eBay they now claim that I must have never had such a listing as they show NO ACTIVITY on my seller account over the last 90 days. Since at the time of this writing, it was listed on eBay 15 days ago and I still have the link to the now non-existent listing saved, both on the PIETECH web page and other media as well, I am very certain that it wasn’t a dream.

This, of course, happened on the same day that YouTube issued another crack-down on anyone speaking about corruption within the US election, immediately removing entire channels for simply voicing an opinion. These are online corporate strong-arm tactics at their worst and simply underline the need for private web sites to voice those opinions and highlight relevant facts.

Maybe we need to start an old fashioned “web ring” as a “No Censorship Zone”.

I have experienced this type of censorship before, but I really was hoping that we as a people had gotten past this covert draconianism (echoes of the “cold war”) but apparently not.

I suppose that I should actually take this as a form of encouragement. After all, if there was “nothing to it” nobody would take the time to censor it and if I weren’t on the right track it would not be perceived as a threat within some corporate-type organization.

I will make a new listing for a place to purchase the manual and I will keep publishing the ongoing work with “reactionless propulsion” as public as possible, after all there is at least some “safety in numbers”.

I will also begin the creation of a private online store so that the likes of eBay and Amazon will have no control over what is listed, said, printed or sold. Maybe I will host my own videos as well… We shall see…

Thanks for letting me rant! Good day.

PIETECH P.6 – Web Site Active, Manual is Ready, 3-planet System Testing, & Possible Changes to the Weights

The Web Site

 The web site is officially up and running! I am definitely not a web page builder, but thanks to some awesome open source software (Open Element) and a very cost effective web hosting company (https://www.hostens.com) who also offer a suite of programs free with the service, www.stclairtech.tech is live.

Eventually this blog may migrate to the www.stclairtech.tech site.

The Manual

The PIE BUILDER’S MANUAL is complete as well and there are links to it from the stclairtech web site. I have listed it on eBay either as a downloadable PDF formatted e-book or as a paper manual. The paper manual also includes the downloadable version and they both come with links to exclusive manual “companion videos”.

The PIE 4.3

The PIE 4.3 has the new motor installed, and the RPMs are just where I expected them to be. The 24v motor is very strong and seems to do a great job of maintaining a stable speed under load. I thought I was ready to build the second wheel, but building the web site gave me some time to think. There are some modifications and variations I want to explore and experiment with as the building continues.

1st I definitely want to try an odd number of planet gears. One gear works better than tow, so I need to see if that is going to continue to change results as the number of gears increases.

2nd I want to add an electrical circuit to the drive motor that can instantly vary the speed it runs. Since I know that if it is allowed to slow when the weight is leaving the center and accelerating in velocity (power stroke) the thrust is dramatically reduced, it stands to reason that inverting this RPM drop into an RPM increase may lead to better results. This could be somewhat accomplished with matching offset drive sprockets, but I think that faster translations between speeds may be more effective….

3rd I want to increase the efficiency of the weights… But how? The answer to this may have already been answered more than 85 years ago by Mr. Harry W. Bull of Syracuse, NY with a device he called the “Propulsor”. This led to an OMG moment…

OMG Moment:

The H.W. Bull “Propulsor”:

In January of 1935 Harry W. Bull of Syracuse NY was featured in a Popular Science article for his invention known as a “Reaction Motor” which came to be known as the “Propulsor”. This design uses 2 equal weights that are slammed into opposite ends of a tube, one weight hits a solid stop while the other hits a “spring” stop. This creates a differential in the efficiency of the “stopping” of the weights. The solid hit creates sound and heat as waste energies while the “spring” end transmits the directional force more efficiently. Like the difference between a steel and a “dead-blow” hammer.

An interesting chapter in the professional life of Harry Bull is available online at http://epizodsspace.airbase.ru/bibl/inostr-yazyki/iaa/1989/Winter_Harry_Bull_American_Rocket_Pioneer.pdf  . On pages 308 & 309 of this volume of a much larger book, the propulsor is briefly discussed.

Of course, Mr. Bull’s work with the Propulsor was immediately rebuffed  by the “scholars” of the time and was publicly denounced as a “fallacious” in 1947, just as all other attempts at a reactionless drive have been and still are today.

Harry W. Bull Pendulum Testing

Basic Principal of Propulsor
 

Back to PIE 4.3

What if the PIE’s weights were “dead-blow”? Since a dead-blow hammer effectively transmits more force in every blow than a plain hammer because it has almost no “bounce-back”, I think that a similar design could be used for the weights which would then transmit their power more effectively with less wasted energy. The reason it transmits power more efficiently is because it lengthens the TIME the contact blow happens! Time, the length of time that virtually any impulse drive uses to produce directional force is a critical feature in successful operation!

3-Planet System

Current Work

Currently the PIE 4.3 has the option of 2 or 3 planet gears. The 3-gear design just makes sense to me, but testing will tell the story there. There is a motor speed controller currently ordered and I am building more weights to experiment with. 

I have just begun testing the 3-planet set-up and I will post more as I go, but there is a video of an initial test run available on YouTube and BitChute (links below).

PIETECH P.4, Coming Soon, a PITECH Builders’ Manual, Also Continuing the PIE 4.3’s Progress

 

PIETECH Manual: There has been a “Manual” in the works for a while now. It is coming together well and once it is completed it should be a valuable resource for anyone wanting to experiment with Inertial Propulsion without spending untold hours with trial and error testing and expensive components that may not be exactly what is necessary. I have several reasonably complete drafts sent out to other people familiar with this technology for their opinions and criticism. Below is a preview shot of the Cover and the Table of Contents as it is right now.

I am hoping to have this available before the end of the year!

PIETECH Manual Cover

There is also a section within the manual that explains the mechanisms which create the driving force in greater detail than has ever been published, to the best of my knowledge. Color photos and detailed instructions means that little or no math is necessary to follow along, build a working PIE 1.0 or 2.0, and gain a better understanding of the inertial propulsion principals proven to work via the PIE.

  
PIETECH Manual TOC 


Continuing on with the PIE 4.3: Now I am preparing to expand the PIE 4.3 into a 2-wheeled unit running in the 200 to 300 RPM range. Tests have proven the possibility of running RPMs in the 850 to 1000 range, but the components would need a pretty severe redesign in order to sustain those RPMs for more than a minute or two, so I am planning on staying under 500 RPMs for now.

Component Failure: The damage from running at full speed (around 875 RPM) is significant. Both outer stops were broken (twice each), and the sprocket gears used as the planet gears have many bent teeth.

Much of that damage was incurred when the outer stop(s) broke and the weight could jam the assembly. That is also when timing would jump.

“Overspeed” Gear Damage

Possible Gear Changes: Notably the sun gear is completely undamaged! Since there is no damage there and considering the severe pounding the gears in the PIE 2.0 suffered with only minor issues (spot welds breaking), I am reluctant to purchase expensive spur gears which will absolutely have weaker teeth than my homemade ones. Better welding, and perhaps a coating should make perfectly acceptable gears that will stand the abuse of slinging the PIE’s weights.

Sprockets for Now: I will probably continue to use the sprockets as planet gears for now, but if they continue having damage issues they will need improvements to minimize the problem.

The sprockets I am using in the PIE 4.3, they are 40A26 sprockets with a 1” center hole. When I weld in the rods, I could skip every other space and that would make 13 tooth gears that would be much stronger and mesh with better precision than just welding rods to a flat pulley.

Those sprockets are very inexpensive from https://www.surpluscenter.com (around $3 US each at this time) and they are easily welded.

40A26 Hubless Sprocket

Adding to the PIE 4.3: I now know for a fact that the PIE 4.3 produces 20 oz. of thrust at 275 RPMs, and it runs smoothly at that speed. A second wheel is being added, and it will need to be timed to the first wheel, so a chain drive is being planned out for the drive. I would ideally be able to test with both synchronized “sympathetic” spin wheels and also test with synchronized but “opposing” spin wheels and switch directions as easily as rerouting the chain and having a second set of weights. Time will tell how that works out.

Wheel Configuration: It is VERY tempting to stack the wheels up for this higher speed unit, like the PIE 2.0, but I think it should be a side-by-side to make the switching of directions as simple as possible. I suppose the question should be regarding the placement of the second wheel. Beside the 1st one or in front of it? Perhaps that is something else that should be “changeable” for experimentation purposes as well…

MORE TO COME SOON

PIETECH V.1, P. 3: PIE 4.3 has a Brand-New Cart, 1st “On-Wheels” Test

 I am now actively conducting thrust tests on the PIE 4.3 with positive results. 

Since it certainly appears to have a lot of propulsive force in bench tests and is rather unruly on the bench, it seems that a heavy and sturdy cart should be used. 

I have modified a steel cart, which I had originally built for an entirely different purpose, just to be the new PIE 4.3’s cart complete with solid solid tires and ball bearing wheels.

 
New Cart With New Wheels

It took several runs at nearly full speed to properly adjust the sun gear for forward thrust without pulling to one side or the other. During those test runs, there was enough force to move the cart forward and slide the wheels sideways approximately 10 inches.

 
Mounting The PIE 4.3 To The New Cart

During those test runs, one outer stop broke and the excessive lash on one of the planet gears caused it to skip timing, but even though weaknesses were obvious the overall test was successful.

PIE 4.3 On Its Wheels After First Round Of Testing

The cart and PIE 4.3 total assembly weight is 130 lbs. New ball bearing wheels with solid rubber tires allow it to roll smoothly on a concrete floor, although some places on my shop floor are better than others. I have several vehicles in different states of disassembly in the shop, so I was limited to a spot where the floor is not quite as smooth so all tests have been repeated in the same “wheel tracks” to be certain that variances in the floor would not skew the numbers. All thrust and resistance tests are being measured using a digital scale.

So, on to the numbers for THIS test sequence.

Unit weight: 130 LBS.

Number of flexplate wheels: 1

Number of weights: 2

Mass of weights: 1.9 OZ.

RPM of flexplate: 275

Rolling resistance “off”: 40 OZ.

Rolling resistance “running”: 20 OZ

Result: 20 OZ of forward thrust – running at 275 RPMs.

PIETECH V.1, P. 2: Redesigned Sun Gear Makes This Model The “PIE 4.3”:

 

Inverted Chain Sun Gear

I am really pleased with the raw power that the PIE 4.0 exhibits. This power is still quite wild and unrefined, but it is impressive, nonetheless.

I was happy with the inverted chain design, but I quickly saw some issues that would give me trouble keeping the PIE running. Mainly the width of the chain is too narrow to allow for wheel run-out and axle deviations. The main wheel is expected to deflect some and I am not using a precision sun gear axle so I have no realistic expectation of it being perfectly straight.

Narrow Chain/Gear Mating Area

Now the sun gear has now been redesigned/improved. It still functions as an inverted chain but rather than roller chain, 8mm (5/16”) rods are used. The new sun gear width is 30mm (1-3/16”) so there is plenty of room to change designs.


Redesigned Sun Gear

The new sun gear is made from two #40-26 tooth sprockets with the teeth cut nearly off and 8mm (5/16”) rods welded into the remaining tooth divots. A piece of 1” steel rod with the center drilled to 5/8” is used for the center of the gear. The sprockets are welded to the center rod and the 5/16” rods ae then welded in place.

Bench testing is showing that adjusting the sun gear’s timing by as little as 1 or 2 teeth (13 to 23 degrees) changes the direction of thrust dramatically. 

Below is a video of the new sun gear set for forward motion and PIE clamped firmly to the bench.

I am planning on doing more extensive testing in the next days and weeks, including the use of an inverter to make the drive portable for vehicle testing!

It has occurred to me that since the PIE 4.0 has already gone through 2 gear redesigns and a motor swap that this is truly the PIE 4.3, so that is what it shall be known as… PIE 4.3!

PIETECH Volume 1, page 1: PIE 4.0 and PIE 2.0 Thrust Stall Test Results

 

 

 

PIETECH

As we open a new chapter in the PIE project previous chapters are not closed, instead they continue as the earliest pioneering efforts put forth leading to PIETECH and will undergo more extensive power in/out ratio testing for scientific purposes.

The PIE 1.0 & 2.0 are also the necessary “trainers” to teach the concepts of PIETECH, and actual building plans are forthcoming within the next few months!

Update added: The PIE 2.0 requires just over 30 oz of thrust to self-propel as seen in the earlier posted video. Another test was run, using weights placed in front of the PIE 2.0. The weights were added until it would not move them, then backed off until movement was just apparent. Then a digital scale was used to push the whole rig forward in order to determine maximum thrust (stall method). This test was repeated a total of 8 times with identical results.

Maximum thrust is now calculated at 230 oz which is 14.375 lbs or 6.52 kg.

Bryan-

PIE 3.0 is a hybrid design which has been which has some unique features which include an active RPM control system using offset pivots. The PIE 3.0 has thus far shown itself to have tremendous power potential but the early tests have proven internal stresses which are very difficult to contain. This 3.0 design is a collaborative effort being developed in a separate lab.

PIE 4.0 is a high-speed PIE designed to run well above the speeds of the PIE 1.0 & 2.0 and designed to explore the power of speed v. weight. Early designs have focused on increasing the mass of the weights, and has proven that increasing the mass is effective to a point but that increasing the speed has a much greater effect with very small incremental changes.

 

High-Speed Planetary Gears

The fist obstacle to a high-speed drive is the planetary gear set. While high speed spur gears are available commercially, the cost for these gears tends to be prohibitive for experimental use in which component damage is rather common.

The Planetary gears need to be able to smoothly run at speeds exceeding 1000 RPMs as well as run within reasonably acceptable noise levels.

1st Experimental Gear Set

The first experimental high-speed gears have been made with reinforced cloth covered flexible material from 14mm pitch industrial timing belts, and although this is very quiet, they flex too much and timing between gears is impossible to hold. This may be revisited another time but is not considered viable for experimental use right now.

 

2nd Experimental Gear Set

It has been decided (for now) to use chain sprockets for the planet gears and an inverted chain drive sun gear. The inverted chain drive is simply a sprocket with the teeth cut down about 90% of the way. A roller chain is wrapped onto the gear and the divots formed at the bottom of the teeth hold the chain so it cannot slip. The chain ends are connected with a standard connector and has not had any need for further work or welding so far.

The only problem experienced with this has been that of run-out due to the sun gear axle getting bent slightly and the deflection of the flexplate. The (possible) solution to those issues has been worked out and will be reported here when it is unveiled.

 

The PIE 4.0

The new PIE 4.0 has now been bench run. It uses very low mass (1.94oz) weights and a 110 volt motor to spin it. The RPM tested at this point is 850 (+/- 10 RPMs).

The high RPM certainly does make a difference, as the PIE proceeded to dump the bench and its contents the 1st time and then with the 2nd run (which was videoed) it pulled itself out of the c-clamp holding it to the bench. That is a lot more power than was anticipated.

Volume 2 Page 15, PIE 4.0, The High Speed PIE:

PIE 4.0

The latest incarnation of the PIE is kind of a step back to an earlier design as well as a step forward to push the limits of PIETECH possibilities.

 


I am using a single wheel (for now) with a much lighter weight, even lighter than the PIE 1.0 design. I am trying out a quiet gear set which uses a 14mm pitch timing belt as the teeth which is fastened to the same size (3.5″) steel pulley as used on the PIE 1.0 & 2.0, and although it is quieter I am not sure if the teeth are robust enough to use as a spur gear.

Initial testing of the PIE 4.0 is very encouraging, although there are some small issues arising from the increased speed which has currently been measured at just over 750 RPMs. The most serious issue has been the used motor I pulled off of the storage shelf. Although the 110 volt motor was marked as “Good” because it runs well without a load, it quickly overheats and shuts down when it is turning the PIE4.0. The other issue is the soft gear design which seems to work well most of the time, but has “slipped” out of time on several test runs. I may revert to the welded steel gears before I am done since I still do not feel that purchasing expensive spur gears in this size range, just to risk having them destroyed if the design fails elsewhere, is an acceptable risk. Eventually I am sure that it will become necessary in order to achieve high speeds for extended periods of time.

The lighter weights (2 oz. including the pivot bushing) are actually performing better than expected as thrust becomes readily apparent in the 100 to 200 RPM range, although a better study of this is required.

The PIE 4.0 has only been bench tested so far, but it easily moves my bench around when it is clamped to the surface of it. Since the PIE 2.0 was just barely able to move the bench, I am encouraged to keep pushing forward with this high speed unit.


Comments about Comments, and Thank You

I have received a number of comments on YouTube, Bit Chute and by other means regarding the inefficiency of this design, and how other designs are soooo much more efficient and can produce these vast amounts of thrust, how this will never work and I am wasting my time chasing this dream.

I have been pointed towards many fine inventor’s works and have had private message conversations with some about some of these.

Here is the deal:

1- I am going to pursue this to some sort of conclusion, it will either be successful or not. 

2- There are those who want this stopped.

3- There are others who think there is a better way but have not built a prototype.

4- There are those who don’t give a crap but like to make fun of other’s efforts.

5- There is always “self doubt” when trudging through the swamp of the unknown.

6- Do not try to force your opinions on me and I will not try to force mine on you.

6- Tell me it can’t be done and watch me go, but do not get in the way.

I was going to post specifics of this here, but I will not. I respect everyone’s opinions even though I may not agree with them.

Please be respectful and comment any ideas you have, they will be respected in like manner.

One last thought today, “Thank You For Your Interest So Far… More To Come Soon!!!”

New Announcements, Global Collaboration, and “PIETECH Electric Propulsion”:

 

Announcement:

Announcing “PIETECH Electric Propulsion”:

It has been a couple of weeks since my last post, but I do not want anyone to think I am not actively pursuing this quest for universal electric propulsion. The Grassroots Mechanic Movement continues the “Open Source” mission to see this technology advance and freely share information. The Grassroots Mechanic Movement is also in a well controlled growth period which will be branching out creating a somewhat separate entity which will be the “industrial development” branch known as “PIETECH Electric Propulsion” which still needs a logo.

Everything here on The Grassroots Mechanic Movement blog remains free and Open Source always, but PIETECH Electric Propulsion is going to allow the PIE technology to expand into the industrial mainstream as this still-infant technology grows and matures.

Current Work:

Currently I am continuing the R&D work necessary to advance the technology of the PIEs 1 & 2, and I am working towards a higher-speed PIE system that should be capable of continuous run speeds of 800 to 2000 RPMs.

I am also collaborating with other researchers around the world who are working toward a similar goal of cheap, clean, electric propulsion for vehicles of different types. This dynamic research is advancing well and will be announced when those independent researchers choose to allow the release of information (their work, their choice).

I am currently working on an instruction manual for those wanting to build a PIE 1.0 and/or 2.0. This will include specs, dimensions, building techniques, photos, reference materials, and hopefully links to videos. Although this tech is open source, I do believe that there are those who are very serious about building and would benefit from detailed instructions. Any proceeds from manual sales will directly help finance PIETECH research. I am hoping to have this material available by the end of 2020.

Review:

Let’s review where we stand in the “public” development of this technology. I say “public” because it has come to light that these types of tech have been used in satellites since sometime in the early 1960s, but it was just recently declassified… Maybe because of Space-X?

1- We have proven the theories of inertial propulsion are viable, as have others such as Steve Hampton and Mike Gamble neither of whom have I had any contact with at this time.

2- We have also proven the PIE design to be inexpensively reproducible.

3- We have obtained measurable results when used as an electric hybrid power source in a motor vehicle.

4- We have proven that there is no need for a counter-rotating assembly in the low-speed PIE drives.

5- We have proven that rotational speed and timing have a dramatic effect on the amount of thrust (maybe more important than the amount of weight?).

6- We have seen, measured, and proven the effects of both “time” and “timing” within the operation of the PIE. Time somewhat analogous with RPMs and timing is a given physical position within a time frame.

Current Developmental Position:

Now that we have “done it” by proving the concept beyond any doubt. It is time to design a way to put it to use. This means designing a smaller yet more powerful system that delivers clean, stable, and (hopefully) quiet thrust for common use in vehicles.

It has been publicly stated by experts (and I quote one of them) that this type of technology “…will never blast us into space…”, but the same PhD who publicly stated that would not acknowledge the potential usefulness as an electric drive for terrestrial vehicles (wheeled or otherwise). But the advances made in my lab (and others), working on a shoestring budget, and in less than a years’ time, seem to indicate the possible fallacy of that statement.

I BELIEVE that if we work together and collaborate as a community of people, each with his or her own individual skill sets, we can achieve great things!

Some will be mathematicians, while others have great mechanical prowess, and yet others may simply enjoy working on individual components of a larger system. PhD’s and dropouts, mechanics and accountants, pilots and hermits, all working together in harmony toward a greater goal. Impossible? Maybe. Worth trying? Definitely!

When I can foresee components from different systems being used in an assembly together, I feel that I am looking at the future for PIETECH, Dean Drives, Cooke Drives, Gyro Build and others!

Coming Next: The High Speed PIETECH system and Continuing PIE 2.0 Testing…

Volume 2, Page 14, Re-Phasing the PIE 2.0 and Ground-Test #2 – SUCCESS!!!:

Re-phasing for Performance


Since the PIE 2.0 did not perform as well as expected on the “self-propulsion” portion of testing, it was removed from the pallet for rework on the work bench. The phasing of the upper and lower wheels is the primary area to be reworked as the possible answer to its poor performance.

The PIE 2.0 was not built for easy phase adjustments, so the rework included the removal of all planet gears and axles. The rework is a re-phase of the wheels from a 90-degree offset to a 0-degree offset.

It would be much better to change the phase offset in smaller increments (say 10, 20 or even 40) but since this is the way already built into the design, this is how it is being done.

Fast Forward a Couple of Days Later and “Ground Test #2”…

That has done it! The re-phasing has made significant improvements in the quest for “self-propulsion”! It will now work its way across the garage floor under its own power with nothing driving the wheels!

The upper planet gears and the lower ones now share the same axles, and the wheeled trolley has been made robust with a tubular steel frame and metal bearings as wheels.

 

I am posting 4 self-propulsion videos to YouTube and BitChute to get maximum viewer coverage and get the information out to everyone.

Regarding subject of re-phasing:

There is a chain sprocket on both wheels and that could be used to drive each wheel independently. A drive chain to each wheel, and the chain can be switched tooth by tooth or the drive sprocket(s) can be made adjustable. A split jackshaft with an adjustment mechanism could be utilized to perform phase adjustments “on the fly” without shutting the PIE down.

More to come soon…
