Hi All,
I found this video today and maybe this would be a experiment I will try.
What do you all think?

Tom.
Come on Tommey, surely, you can't be that gullible! Germany and Italy working together, now that sounds like a horrible history repeating itself. ;D It can only result in pain. Contact the chap and see what he wants..
Hi pomo,
I thought it would be interesting in making a simple version with a dc motor and a low rpm hub motor as a dc generator.
This way you can show better input vs output of watts.
The flywheel could be a weight lifter 45lb weight that anyone can get from Walmart.
This I can do in a few months after my move to Florida, just a thought.
Tom
Hi All,
I will explain how the experiment should be ran.
The dc motor is powered by 48v dc batteries as the speed increase no power is being pulled from the 48v hub generator.
When the dc motor reaches top speed of about 3000 rpm's, a micro controller takes over.
What the controller does is turn off the dc motor and allow power to be pulled from the generator for a few seconds or what ever timing is needed to make it the most efficient to recharge battery bank.
The flywheel acts a mechanical capacitor that store inertia.
Then the dc motor kicks back on while the generator goes into free spin and cycle off and on again.
Tom.
Could you use a couple of secondhand car starter motors at £10 each?
Hi Paul,
I have most of the parts like the motor and micro controllers chips I can program, I will need to get another 1000w hub motor that will cost about $200.00 and 45lb weight.
The rest is just labor and small parts.
Tom...
Tommy,
I really like the youtube video. Very simple and straight forward. I doubt that there is
any way to prove operation over the internet but this comes as close as I have seen.
One thing is a little funky is the fact that his power tools have no AC plugs on their
cables!
The German motor painter gold is probably a high efficiency Siemens motor. High
efficiency AC motors are usually painted that gold color. One might be able to get even
higher efficiency by running a 240Vac/220Vac motor on 120Vac. More recent date code
motors are even more efficient then older motors with similar ID's. The most recent
Siemens H.E. AC motors are wound with copper tape rather then wire.
A good source of a balanced flywheel is spare parts is from exercise equipment like an
inplace bicycle. They have 40 pound flywheels. I was planning a similar setup and I wanted
to use two such flywheels. I found that a new bench-mount buffer-wheel 3600RPM grinder
could be used as the bearing pillow block assembly by mounting one flywheel on each side of the
grinders shafts and then ignoring the grinder's motor. Pulleys on each inside shaft would transfer
power. A good source for an efficient 96 VDC generator is a new spare DC Treadmill replacement
motors. I kind of like the concept of using toothed rubber belts like they use on some motorcycles
rather than a chain drive as it keeps components mechanically synchronized but would not require
oil for lubrication.
Just throwing out some ides that I've looked at.
Build it Tommy ! That would be great !!
In my humble opinion Two things at work here..
Timing: The rubber belts give "play" in timing and (de)synchronizing As they are not a fixed dimension, the rubber is able to breath... aka live..aka wave..
Relative motion: The relative rotation of any inertial attractive mass is a matter of dimension
I would like to know one thing.
If O/P is more than I/P in that setup, why do we need motor and generator? One wheel on the left, another wheel on the right with a huge flywheel in between connected to both wheels by belt arrangement should make a perpetual device! because as I guess energy is created in that setup by flywheel only! Standard motor and standard generator are built conforming to conservation law.
Hi Newton,
Dc motor like rpms, so if you run the motor at higher speeds you will use less energy to keep it running.
Hub motors only have a limited speed due to the fact so many pulse can take up lots of energy in a single rotation.
This is another reason why a 4:1 ratio is needed.
The real trick is to have a timing circuit using a micro controller to allow both input&output so when the generator pulls energy it is not while the dc motor is on.
Something like this:
1) motor on---generator off = input watts
2) flywheel increase speed =no load
3) motor off---generator on = charging watts
4) flywheel decrease speed = load
1)motor on---generator off = input watts
2) flywheel increase speed =no load
3) motor off---generator on = charging watts
4) flywheel decrease speed = load
And so on.
Tom

Simple answer: To animate inanimate solid matter, and maintain VELOCITY.
You "guess" correctly. "Energy" can be generated, and is "created" upon acceleration of matter.
Standard motors and generators are fine AS IS. Some are better than others for different designs.
You can read more about it (older work) here: http://www.backgauges.com/Gen-E-Sys%20II/
My latest work is "light years" past this and anything shown on that website. Simple truth that many will deny.
BTW: Tommey, you are invited.
Imagine how many battery's you can hide in that blue container, enough to drive a tesla for 100 miles!
I don't think you can continue to experimenting in heaven so don't waste your time replicating a YouTube free energy video ;D

You are right, thanks because I forgot to mention that video. What is shown in that video goes against every experiment done by
myself. Something is not "write" with that video, in reality.
Tom is correct that the motor must not be connected when the generator is generating.
I, and another have already built the boards to do the switching and a lot more: but there are far better ways to go.
Lot's of batteries inside: probably so.

You got me there, enjoy building your stuff but why not build something useful.
Why would someone build a motor driving a generator?
Hi scratch,
Yes you got me there also, but wait.
What if you build this simple design with a twist of smarts.
What about using my idea where the motor is control to speed up the flywheel to store mechanical energy?
When the flywheel is up to speed it takes less energy to keep it there, while I believe it should be harder to slow down under a simple load.
Almost like a car going 100 mph and trying to stop it is a short distant. lots of energy stopping that large mass in a short time.
So, this is my experiment is to test this theory. If you energize the motor for a few seconds while at full speed of the flywheel, could you then turn off the motor and energize the generator for a longer time while using the less amount of energy to bring it the flywheel back up to speed?
Has anyone try that?
:-)

A flywheel is only an energy storage device-like a capacitor or battery.
There is only losses in a flywheel system like you propose. Those losses include belt friction,bearing friction and windage. I have already debunked the video you posted in your first post Tommy--can be seen on the ! debunk this! thread.

True in the way you would most likely use one. Not true in ALL cases.
Flywheels can and do generate "energy".
If they were not capable of it, then please explain what you propose to get around Nature manifesting Kinetic energy WITHIN ALL MATTER IN MOTION.
Please start with 1/2mv^2.

Hi All,
What is a flywheel?
A flywheel act like a capacitor, but more efficient like a mechanical horse.
They are use in most engine and even power stations to help keeps energy at a constant.
They also are large mass that do have a light drag, but with magnet bearings that could be solve.
Try stopping a train while it's moving, with the mass being so great they take miles to stop.

The energy dissipated to stop the train,will be the same amount that it took to get the train up to speed in the first place-minus losses such as wind drag,wheel and bearing friction,and heat dissipation-including that from the engine it self
Brad.
Wish you the best with your flywheel experiments Tommey. ConVoiLon has done some flywheel experiments that I think are interesting and genuine. I think his experiments show that flywheels have more use then we currently know about.
https://www.youtube.com/watch?v=xvhwEDeEp18
Lidmotor has done a kind of replication.... of the SAME video
But he " forgot" the flywheel . : )
https://www.youtube.com/watch?v=tWuVUDjWGSo
Hi Cherryman,
I would question that video due to the fact of super capacitors .
I think most people have not fully understand what my project would do.
The drive motor would not rotate when the power is cut off due to one way bearing step up. In other words as the motor increase the flywheel rpm's and then is turn off, the flywheel goes into free spin without rotating the dc drive motor.
This is when power is pulled from the flywheel for a few seconds, at that moment the generator stops pulling power and kicks on the drive motor back up to the rpm's the flywheel was.
This also would make it more efficient then having a constant mechanical load from the drive motor while the flywheel spins.

Hi again TV,
In the News section of this forum there is a sticky about the size of pictures for this forum. What it says basically is to keep pictures down to 1024 pixels wide at the most and recommends that for most pictures 800 pixels wide is sufficient. There is also a tutorial in that thread for using Paint to resize your picture. I think FPC is easier but whatever works for you is fine. Thanks for being willing to do that. Some on here just won't take the time or effort to make things easier for everyone.

Tinman,
Question: Where do you have the right to call other out while you have made claims that is questionable in the past like many of us.
This is a experiment, so I don't understand why you would add to these comments in a negative way.
I understand you like to post your stuff, but let others do the same, and if they don't work then really we all learn don't we?
A flywheel does have a secret energy that most can't see, as the inertia builds up to a maximum speed the atoms that hold the flywheel together explodes outward.
This is also based on the theory of the Clem's engine and Viktor Schauberger vortex implosion motor.
The most important part of this experiment is bringing it up to a high enough speed where the generator pulls enough energy out where the input is far less.
This is a good experiment to try, but I won't be able until I move back to Florida is a few months.
We all learn from building stuff, sometimes it's best to see what others have in mind then someone own opinions of how it should work.

QuoteThis is a experiment, so I don't understand why you would add to these comments in a negative way.
If you think my being honest is negative,then there is not much i can do about that.
TemperaVistitor made a claim,and i only asked that he would back up that claim. He said he could,but it would not be free--will cost me money. This i object to.
QuoteI understand you like to post your stuff, but let others do the same, and if they don't work then really we all learn don't we?
I also like to try and save people from spending there money on something that has been proven many times not to work--the bug flywheel/motor/generator setup.
QuoteA flywheel does have a secret energy that most can't see, as the inertia builds up to a maximum speed the atoms that hold the flywheel together explodes outward.
If the Atoms explode outwards,you have no flywheel any more.
You may be referring to !free electron's! ?,but the flywheel need be submersed in a magnetic field for that,and copper or silver is the best material for the job.
QuoteThe most important part of this experiment is bringing it up to a high enough speed where the generator pulls enough energy out where the input is far less.
The input will always exceed the mechanical output--that is a fact.
Every car has a flywheel,but there is always less HP at the wheels than there is at the motor-regardless of flywheel RPM.
QuoteWe all learn from building stuff, sometimes it's best to see what others have in mind then someone own opinions of how it should work.
Yes,it is always the best way to find out the truth. But remember,many 100s of people have tried this,and all have negative result's. Even science says the flywheel is an energy storing device--not an energy creating device.
I just feel that your time and money would be better spent on your electric bike project--that is an excellent project--i loved it :). But as you say-my thoughts dont really count here--yours do.
So i wish you the best Tom--give it a shot.
Brad
Tinman,
Are you saying the over 100 experiment with a flywheel design is just like my design and theory, I don't think so.
Most have not even try use my idea, so where does this one make it that same as others?
With my design of controlling input and output with a micro controller would be a far step ahead of what other have done.
I though you did make a claim, but off hand I don't know the details.
If I recall you did post your free energy on this forum, and claim the men in black came to your home.
I don't really know, but maybe you could explain it much better.
;-)
Sorry guys but neither one of you is totally correct in your assumptions about flywheels. I have done the exact same testing as Tommey is suggesting using a microprocessor to control the on and off times of the motor and load. A couple of years ago I spent a few hundred hours working with that setup and adjusting the on and off times and other things to see if I could get more out than I put in. I found the flywheel extended my run times by quite a bit but I did not see any OU. So my conclusion was that the flywheel is very useful for making a more efficient system but I never saw more out of the total system than what I put in. Maybe a larger flywheel would show something different or some other parameter change might make the difference.
Respectfully,
Carroll

QuoteAre you saying the over 100 experiment with a flywheel design is just like my design and theory, I don't think so.
The internal combustion engine work's like your theory-where a quick pulse of energy is sent and stored in the flywheel,and then during the 3 strokes(assuming we are looking at a 4 stroke engine)the engine is not producing power,the flywheel continues to deliver the stored energy to what ever load it is driving.
I myself have made such a setup using a solenoid driven electric engine,where a load is drawn from the flywheel when the prime mover is switched off.
QuoteMost have not even try use my idea, so where does this one make it that same as others?
With my design of controlling input and output with a micro controller would be a far step ahead of what other have done.
A simple pulse motor work's in the very same way your design dose,where the coil(flywheel) is energized,and then a load is drawn from that stored energy during the off period of the pulsing coil.
But i look forward to your build and results,as they are always good.

Hi Tinman,
Not that you're wrong or right, but sometimes other have to take a shot at maybe a different way of doing the same experiment.
I do like those 3 phase dc motors you get out of washing machines, they seem like a good low rpm generator for this type of experiment.
We all have skills, I love building stuff, so it's not a waste at all. Just something different to try.
Tom
Hi Tom,
No my setup did not have a one way clutch bearing. Also my system was pretty small. My flywheel weight was about 10 pounds. I did use a very efficient switching circuit using mosfets and mosfet driver chips for fast on and off times with very low voltage drop during the on times. I also am looking forward to your build. It will be interesting to see if you are able to get more out than in with a larger system. Your builds are always impressive. Thanks to you and Brad for sharing what you do.

Yes,the smart drive motors are very efficient and have a lot of torque at low RPM.
They would be ideal for your DUT.
I am in the process of getting all the parts together to build my grandsons an electric gocart using one of those motors
Brad
Hi Tinman,
I would think it would work great with a homemade driver so each pulse could recover BEMF as the motor is running.
You could arrange the coil to run on lower voltage, don't know how many volts they use, but it's a dc pulse motor and maybe it could do better then a hub motor.
What a voltage they run on?
Tom.

There are 4 types-or series as we call them,then ther is the cogless ones as well,which make great wind generators. I will provide a link below for a video that explains the difference between them,but basically it's the voltage the motors run on. The early ones use low voltage motor's,which is nothing more than wires size and turn amounts per coil. The later models run on a higher voltage,and so have more turns per coil using smaller gauge wire.
I would look for a 100 or 80 series,as these were the lower voltage motors,and easier to parallel the windings to run them on 12 volts.
I would keep using AC to run them,as there a push/pull motor,and running them on pulsed DC causes a large drop in torque.
im not sure if you have fisher and paykel washing machines over ther,but maytag and whirlpool also use them-the smart drive motor.

Motors come in many flavors, just about all can be used in various designs. One personal favorite is low rpm high voltage PMAC ... aka DC brushless. (see small photos of 11.8kw liquid cooled 600v 600rpm used in the "evidence" photo of yesterday & not put back up since)
BEMF recovery I've learned does indeed help but is not an absolute requirement, and you don't need to build it - save yourself
TIME and just buy what you need. "They already exist".
I encourage you to take your
TIME and read this on Engines vs. EN-GEN's http://www.backgauges.com/Gen-E-Sys%20II/en-gen.html - in it you will find it supplements what TINMAN wrote above.
On that page please notice the "The PMS 120 7kW is a very efficient motor, they are real and out there for you." Also a brushless used in my many designs/builds/research. With more to "share" it is all about

Hi Tommey,
This is just an idea.
Get rid of the generator and turn the flywheel into the actual generator by using facing angled magnets on the perimeter. This is something I've been playing with, with interesting results. It's not new there are many patents that show a similar structure for reducing driving torque. I've attached a pic of my simple prototypes the larger one performs the best. By best I mean shorting out the generator coil (with iron core) and spinning barely cogs the rotor, even better with air core as your only dealing with friction losses and boundary effects.
Here are a couple patents of similar structure, there are many more if you search around.

HI Dream,
I think the real problem is magnet flux becomes weaker due to the angle.
The stronger the field the better the output, and greater input load.
I believe this magnet design I came up with might work even better.
It called a total flux generator with some moving parts.

Hi Tom,
I made a quick test to show the effect I'm seeing. Most conventional generators I have just stop after the motor is shut off with a load, this design will coast down. The output is reduced compared to a standard design but the trade off is being able to use a smaller motor at a higher rpm with a longer spin down time while still attached to the load.

I like your belt design, would those be ring magnets with a cable through the middle?
