OK, I know I should concentrate just in one idea, but I can't! It's stronger than me! :D
Well, I was thinking: what is the best way to extract electricity from a pendulum?
In other words: what should be the very best design for a "pendulum generator"? I'm not talking about perpetual motion (yet), just want to know how to extract electricity from a pendulum that receives impulse from our bare hands.
What about if we seat in a confortable chair, reading a good book, with a pendulum swinging by our side, and from time to time we raise our arm to give a small boost to the pendulum in order to keep it moving.
What is the very best way to extract electricity from this pendulum, with maximum output wattage? What should be the best design to a pendulum generator with maximum efficiency?
(The weight on the end of the pendulum could be metallic, could be non-magnetic material, or it could be a magnet - what be best to maximize output.)
Any ideas?
this should answer your question...:

where is the " 12 times more output than input, dual mechanical oscillation system ! " ?
we need the data on the output of this beautifull thing ?
If one is talking strictly about a non-compound pendulum with only a small amount of vertical motion allowed at the fulcrum, then perhaps a highly aerodynamic setup involving bending piezos, actuated by the force squaring at perigree intervals....

Efficiency is so very relative, however.

I think I should reformulate:
What is the very best way to extract electricity from this pendulum, with maximum output wattage AND minimum friction (including "magnetic friction" due to Lenz's Law), in order to make it swing for as long as possible?
well, if you use a magnet as a counterweight (being as direct as possible), and allow its swing to pass an inductor coil, this would generate electricity
now, the pendulum has the most momentum at the bottom of its swing, so with previously said method, logically the coil would be placed at the bottom of the arc
the more mass a pendulum has, the more efficient, as well as the length of the "string"
the stronger the magnet is, the more drag it will encounter
similarly, the closer the magnet swings to the coil, the more drag you will induce
neither of which will induce nearly the amount of energy it takes to keep the pendulum going
also, the faster it travels the more drag you will encounter
that is the most direct way i can think of, indirectly i would look at the milkovic 12x machine
while i am partially doubtful it actually does increase output, its the best example of how to have a pendulum generate electricity without any induced drag directly into the pendulum itself
QuoteWhat is the very best way to extract electricity from this pendulum...
That would depend on what you mean by "THIS" pendulum. It's all relative.
From what is given in your description, the least amount of friction may be provided by a fulcrum allowed just enough vertical movement to impinge upon a bending piezo....
And of course, aerodynamic pendulum and swing arm shapes....I would also recommend a dry bearing hub assembly, as is found on the older style roller skates.

remember that gravity is only a return of expended energy, nothing more.

I am Quoteing Mr.Bojangles above,,,,Pendulum sounds good,,,maybe with some left over?
He has said it much better than I,,
What I would add would be,dont stop work
on it and don't stop posting,your results.
Sounds Durn Good to me.
Good Luck and Play SAFE

Butch Lafonte has an interesting design called the Equilibrium Motor, but I can't find it.
Hi Rapadura
What about a passive magnetic bearing at the fulcrum? that would give you an automatic drop at the bottom of the swing,if that's what you want.
peter
Wow... passive magnetic bearing is NASA technology:
http://www.grc.nasa.gov/WWW/spacemech/workshop02/mag-brg.html
Maybe NASA is using overunity in its satellites and don't want to share it with us!
By the way, a pendulum with this passive magnetic bearing at the fulcrum, operating in a vacuum chamber, will stop some day or will swing forever?

this isn't really new, lots of inventors have been making these for at least a decade now, makes one wonder where NASA derived the knowledge for the unit.
I don't know if anybody ever patented it in the civilian realm.
Hi Rapadura
Of course it will not swing forever,I wish,there is air friction for one thing,the biggest prob. is lenz drag on a coil,it always seems to come down to that!! but a friction free fulcrum is a start.
peter
Quotethe biggest prob. is lenz drag on a coil
Which is why I recommended a bending piezo and some vertical freedom for the fulcrum.
Quotea friction free fulcrum is a start.
Which is why I recommended a dry bearing hub. Ever spin a skate wheel from the old 4 wheel style of roller skate? For that matter, a pendulum need not have bearings at all, but instead a good pivot point or 'blade'.
TS
Hi TS
would not a dry bearing hub stop any vertical movement?
peter
A circular hub would, of course, have to be included as part of the fulcrum which is allowed movement. A blade type pivot is even easier and could rest on a covered 'bending piezo' or set of piezos.
TS
Hi TS
I recon that would do it.
peter

Don't just reckon....
(Insert Nike catch phrase here)
lol
I know....let's get Naudin to do it, he likes everything!

Hey peter, but if the pendulum was inside a vacuum chamber? There is no air friction in a vacuum chamber!
With a passive magnetic bearing we have a friction free fulcrum. With a vacuum chamber we have no air friction. The only "friction" is Lenz drag, if we use a coil...
QuoteThe only "friction" is Lenz drag, if we use a coil...
What do you mean, "we"?
I vote
you should try it and let us all know the results of your intrepid contraption so that we may all learn from your bold adventure!
TS
I would love to have a vacuum chamber and passive magnetic bearing... But I think I have no money for it!
Anyway, if there is Lenz drag, it is not worth trying...
QuoteAnyway, if there is Lenz drag, it is not worth trying...
Yeah, Lenz is a drag....
But then so is thinking one needs a vacuum chamber and passive magnetic bearings. Some of the best inventions of mankind were first accomplished with relative junk held together with a 'shoe string'.
Happy trails on your journey, and may you find True Wisdom.

@rapadura;
It's best if you design experiements where you test for only
one form of overunity energy. That means designing the rest
of a device according to consesvation-of-energy design theory.
If you try to include more than one overunity method, at one
time, like Dennis Lee, you end up finding that nothing works,
and you have no way to correct problems that inevitably
develop. It's an error to think overunity energy is everywhere...
it's only somewhere.
So in the pendulum case when you extract energy by any means
you slow it down...it's the experiementers job to then include
an overunity energy gain process to speed it back up.

Actually, the pendulum is one of those peculiar cases (specifically, a compound pendulum) whereby the proper configuration alone, may produce overunity. The principle of pendulaic force squaring shows this to be possible.
If I were new to the arena, I would start by measuring a static fulcrum pendulum's output and experiment, looking for a simple way to cause movement of the fulcrum without decreasing output as compared to the static fulcrum setup. Remember, the pendulum weight itself, makes for an excellent fulcrum.....
Pendulums and piezos are made for each other. Piezo pulses stored in a capacitor or connected to a solenoid can put quite a 'kick' in one's research. There are numerous ways as well, to produce prodigious magnetic field changes with near zero added drag to a rotary magnetic system, over the friction of air and bearing losses alone.
There are truly myriad ways of re-writing the 'Lentz Legacy'.
