I could imagine if you used solar or wind to provide a push every now and again it could be fascinating to see how long it would run for. Particularly if you created multiple magnets and coils to harvest the power in a matching arc shape under the pendulum.
@BrainfooTV Hybrid systems can be wonderfully effective. Purists often miss value because hybrids trouble them. --In your last sentence your modification of the system shown should, if properly piped to the LED, provide continuous light while the pendulum swings. --How about a floor lamp with the footprint of a grandfather clock? How about a half dozen pendulums within of various lengths, all going at once to provide much more light, or where some of those pendulums are charging a battery?
@@johnstrawb3521 I agree, it could be fascinating 👍🏻
You could have the wind or whatever build up energy while the pendulum is swinging away, then release that all at once to give your pendulum a push. Probably want some sort of limiter on there so it only pushes what you lost due to friction and the energy draw from the pendulum. Gravity gives you the rest :)
@@johnstrawb3521 i believe hybrid systems are the best way forward when it comes to all these "green energy solutions" as they scavenge the most amount of energy with the least amount of losses. if a system is built correctly you should see very minimal losses to a point that it runs for a very long time between the need to do maintenance and reset the system, these types of systems are as close to "perpetual motion" as we can/will ever be able to achieve as there will ALWAYS be some kind of maintenance and input energy required and the typical losses through thermodynamics, as well as the effort and materials used to build the system!
@residue junkie every time I have said that I think magnets are a source of almost infinite quantum energy I get shot down in the comments. So I have given up now. I honestly know nothing about the Rothschild's or care to be honest. But Nicola Tesla, Quantum physics and Energy really interest me. People literally stick a magnet together or to a fridge, watch it cling or replel indefinitely and think nothing more of where the energy is coming from.
I've said it before, but building up on this, how about something like a perpetual motion watch mech? Pendulum swings, turning a ratchet, winding up a coil spring, which turns a flywheel, which generates electricity (In milliamps) Mounted on your barley corn head things, a whole field of these could generate significant power??
I can imagine an array of these, so their swings synchronize to produce power at a specified Hz, You could gear them to keep them in sync.
Adding a small wind blade to make sure that energy is input into the system, you could syphon a constant amount.
Certainly has potential.
The ideas for developing an advanced machine are endless but the laws of physics will have their way, but we could figure out a way to use very little to make it work.
The more coils and leds you add the quicker it will slow down as they will just put more drag on the swinging pendulum. The swinging pendulum is similar to stored kinetic energy which is slowly being siphoned off to operate the leds.
I wonder if putting the coil and magnet on the other end, and the pivot point just below it would make better use of the torque generated by that long arm and maybe the motion would last longer.
King of the swingers.
Would a couple of permanent magnets either side of the swing radius (not too close) but enough to have an effect, keep it swinging for longer?
These could literally be put out by the BILLIONS and as long as they do not bump into each other, there would be absolutely zero penalties [unlike some other forms of energy harvesting such as wind mills and solar cells] for stacking them in all 3 dimensions.
But I'm kinda thinking that not a whole lot of people will likely make anything with such a vast array...
Just guessing.
Where I live, personally, if I make one, its going to be REEEEEEELY BIG and work on an 'ever so slightly different' principle.
Because this is one type of recapitulative energy harvesting which can benefit massively with scale, both in the net power gained, but in the net costs being diminished.
but adding coils will load the pendulum so it will slow down faster. each pass will remove energy from the pendulum so it will not swing so high. so you'er have to push it more often or add a motor to do it for you, just like clock did. i think what you have here is a very slow hand cranked generator, with the flywheel replaced with the pendulum.
I always try to remember that every transfer of energy is a loss in the system, so the less stages between the energy supply and the load the better. What would life be like if we could get 100% transfer let alone 100.00000000000000001%
yes that's right - but there are places where a pendulum can be used that is in no good for a crank - a swaying building for example or a barleycorn generator - anywhere that sways and there is input energy - a bridge, a flag etc etc - I don't want to be rude here mate but you may have missed the point
@@ThinkingandTinkeringII may have missed the point, but is the main point that it’s open to discussion.
I think the problem with the pendulum route is that you have to match the frequency of the item swing be it a building or a flag pole to the frequency of the pendulum, don’t you want them to resonate to get the best energy transfer IMHO. Or you’re being pushing when you should be pulling. The lighter flag pole may swing with quite a wide range of frequencies; I thought that idea regarding pendulums were to counter the effect of Vortex shedding and trying to avoid the structure going into destructive resonance.
Still if you don’t post your comments! Correct or not in the eyes of the content creator, then there is no point in having a comments section.
WOW very cool, now just connect that to a couple of nand gates set up as a dc flip flop and it's a clock or a counter.
Different subject but still the same. It seems that the only goal is to turn on a light or make electricity but in many things electricity isn't a necessity. Using a VAWT and not a generator, rather a worm gear and going backwards through your gearbox to create torque from a lot of spins, one could turn a composing drum slowly and if one were artistic, one could make a wind chime that actually played a tune and sell such things and be able to change the drum to have a new tune, sell them to the ritzy titsy that just Loooooooove that kind of suff. Fountains running on Archimedes screws,
Have you seen veljko milkovic and his pendulum
i could see pendulum in the sea as a motion generator? gl
Love the pendulum generator! Is this globe propaganda mixed in? Are you gonna try to reproduce the faucult pendulum results?
Thank you, Robert! As someone studying to become a maths and science teacher, I have to say that you're an inspiration in the way you explain plainly and show with clear practical examples how physical principles work in the real world.
I wish we let kids do more stuff with their own hands in school, and guide them through their own journey of exploration with theory and practice hand-in-hand, rather than force them through a nationwide curriculum with standardized tests, all the time being stuck to a boring computer screen. If that was the case, I think maths and science would be much more popular subjects, that kids might actually learn from.
Reminds me of Gever Tulley's book on "dangerous things" that you should let your children do and his "tinkering school" but that was around 15-20 years ago and I don't know whatever came of the project.
Have a search if it sounds of interest, I'll probably do so when I can spare more than a few seconds to post a comment.
@@matthewellisor5835 cool I'll check it out
I love the way you think! But you're harnessing the energy at the wrong end! Try stopping the pendulum at the opposite end - it's nearly impossible! There's not much movement, but the torque is really high which can be converted into useful energy with a gearbox. You could attach a small "sail" where the weight is so the wind could push it around
They couldn’t use a pendulum at sea, that is why they had to invent the balance wheel.
Actually the design that was finally accepted by the British admiralty after ages and ages was an interesting solution for addressing the swaying that was encountered at sea .
A great docudrama was produced by BBC . It's likely available on YT. .... +The search for longitude+ or in search of longitude .
@@philip5940 Yeah, that was a great series. I just suggested it. A lot of great actors were in it.
Awesome Rob!
I was experimenting with your Barleycorn generator idea and figured what if it was a free moving pendulum instead of a single set axis swing, but instead of a long elastic shaft like the glass fibre rod, I found a shortish spring mounted between the base and the generator frame/case allows the motion of the pendulum to offset against the springs porential this causing it to bob for ages... i redesigned the shape of the barleycorn head into a sort of hollow 3d teardrop shape with the pendulum hanging from the inside top tip of the "droplet"... havent had a chance to fully play with it but it seemed like it had some potential for keeping the pendulum swinging almost seemingly indefinitely...or at least while there is some even occasional disturbance on the teardrop bobber.
wow - it seems we were thinking on the same lines mate - nice one!
Mr. Murray-Smith, you are a real genius !!! And the best of your work is that you provide a lot of inspiration !!! Not to mention your huge enthusiasm !!!
God bless you !!!
I guess if you got full load connected to the coil, the pendulum will stop after just a short time. But it works as an alternative to a flywheel.
I imagine the swing time depends on the electrical load on the generator, correct?
With that pendulum style wonder if a flap or cone or something like it could be made so when swinging one way it would capture the wind, then once it reaches its end point it rotates a 180 and ends up being a point into the wind cutting thru to reach the other end, then rotating the other 180 degrees to end up being a cup into the wind and cycling over and over.
What if you stored the energy and after maybe 6 hours use some of that stored energy to give it another push... this way it will go for AGES TRULLY! :)
You have your latitude and longitude reversed mate . lol 🤣
In addition to a minimal amount of friction, I think the "cogging effect" will diminish the arc of travel, lessening the time it will generate. Still an illuminating demonstration.
Put it in an box frame and coat the working surfaces with PTFE; PTFE/PTFE has a coefficient of friction listed at 0.05% so that should help maintain the pendulum without it being a 'perpetual motion' machine, yet should have a longer operation cycle.
PTFE 'pan repair dry spray coating' is available at many outlets for a reasonable price and applies to most substrates, so it shouldn't take much to modify that cute little ticker lol
My geography is either very wrong, but did you not reverse Latitude and Longitude?
Yes, he did .. poor Robert is going to be embarrassed .. lol 🤣 Time for more coffee!!
Nice idea :)
There's still resistances with the magnet I would imagine. I wonder how long you get with that much span, while powering the LED.
Energy in, energy out I suppose. The game seems to a great extent to be about finding the most efficient or accessible sources to leverage.
0 M G ! I just made myself laugh out loud, uncontrollably! The thought popped into my mind... " Boy, I wish that guy was MY Grandpa!" and then " oh, I mean, little brother." LOL ... Our life courses determine these observations. Thank you, sir, for making the hard one. All my grandchildren watch you, now!
Of course a VAWT winding a clock spring driving an escapement to the pendulum and hey presto, the perpetual blinking LED - thanks for the joy of seeing things cobbled together. - ADDITIONALLY - the electricity generated could charge a capacitor powering a digital display displaying some useful information - ?? Time ??...
Why not use a clockwork to "power" the pendulum?.....another easily 3d printed project available on Thingiverse.
It wouldn't even need to keep time in the traditional sense, just keep the pendulum in motion....
I love it. Now, what if the pendulum was suspended in a vacuum? Perhaps the force of the magnet passing over the coil (outside of the vacuum chamber) would eventually slow the pendulum, but it would take a considerably long time. Now imagine a carriage for the coil(s) in the same shape as the pendulum's arc with multiple coils along the length of travel...
Lies...all lies
Try a 400 day clock . It's called an anniversary clock because you wind it once a year. And the pendulum swings in a circle.
And there just happens to be a riveting docudrama produced by BBC,, actually maybe ABC Australia that tells the story behind invention of the chronometer used and tested by Captain James Cook in "discovery" of Australia . Also during the voyage the Measurement of beginning and end times for transit from Tahiti vantage point of Venus across the sun was observed. Same reading was done from Greenwich . The time discrepancy enabled to calculate the distance of the Earth from the Sun .
Pendulums can swing because of the movement of the earth, OR the wind, OR from water, OR from some other parasympathetic forces.
So if you put them on bridges and overpasses, the resonance of the bridge will cause them to swing [both seismic and automotive induced], as will the natural wind, as will the wind driven by the passing vehicles.
They should, hypothetically then, never cease generating.
I'm pretty sure that, just the fact that gravity is working against a pendulum, there is no way it can actually run 'forever' even if it would run for hundreds of years...
Still, pendulums are awesome power harvesting mechanisms!
We see too far.
Grandfather clocks are spring loaded.
Foucault pendulum's are mechanically moved by motors in all museums.
Welcome to the great deception.
There are nice ideas in the comments how to keep the pendulum running by adding more energy - but actually very good and simple methods were invented centuries ago: just add a suspended weight or a coiled spring - like in a classic pendulum clock that runs for ages. :-) - EDIT: "Escapement" seems to be the right English term to look for.
I've had a idea for while a pendulum that will spin flywheels with gears and magnetics and energy from air to make it all move. This causing the system to be able to run for long periods.
Good job 👏 👍 👌
Now for some more fun, if we could use a little solar power to charge a battery, feed a pulse generator, through an electromagnet to give a gentle thump to the pendulum, the pendulum could be heavier and possibly energize more pickup coils and could possibly run unattended for a very long time.
😀
Lat and long ? - As shown in your video the pendulum on a wire rotates left to right and traverses a separate path with each swing. So the best place for generating is the center of the ark of swing and the swing will last longer as apposed to your fixed swing - But you proved beyond doubt, that you can be a swinger to generate., Even if you are some where lost in Kent.
Cool stuff, gives me an idear, you take that pendulum up into orbit to the lagrange point, where you can be fixed relative to the earths and suns sping i believe it is, thats where you drop the pendulum affixed to a carbon cord back down to earth, and from the earths perspective the pendulum is travelling through the air. Thats where you can affix your led light and generate a blinking LED.
No phallic parts to make this project? Lol. Anyway, so far I have found the most suitable energy generation projects to be the flying kite (still thinking how to keep it flying btw, will have to be perfectly balanced in assembly) and the stirling engine. In India we have more sunlight than anyone can wish for and I would focus it onto one end of a huge stirling engine while burying its cooler end deep into moist soil with heat sinks attached for efficient transfer. The only problem is that for some reason I never fully grasped the engineering sense that makes it work even though there are several designs for it and I could just scale one up but that does not guarantee success.
celestial navigation requires a flat earth 90 degree angle , you cant get a 90 degree angle on a curved surface , its a non seqitor and also if pendulums process then ALL pendulums and cranes would do the same on a globe earth , but they DONT , reality dictates it ,
I have plans to tinker with geo-pendulums.
It may be useless, but it will be something I have a whole lot of designs for.
Its just going to cost me a lot, because of scale.
Great video Rob i have always been fascinated with clocks and pendulums but this also reminds me of the drinking bird toy wich is kind of a pendulum and heat engine combined .I wonder if this could be sized up and use you free wheel device to connect multiple devices together ?
Could you make a complete system that people can recreate in their homes. For example this pendulum paired with the sand battery and a heat exchanger?
Got your latitude and longitude mixed up. Longitude is perpendicular and latitude horizontal…at least it was when I went to school.
I've seen some additional concepts in practice with a pendulum connected to a water pump handle (with a spring to keep the handle up) so that kids could swing the pendulum to pump the water. I always thought that there could be a way with some sensors and magnets to keep the pendulum going to do continuous work...
Had some ideas to use in cooperation with the corona motor. but it requires more metal.
3d print two bushings half inch thick 4 inch in diameter that have a bearing set in the center and a hand full of 3/8ths inch holes equally spaced radially no further than a eighth inch from the edge/circumference. fill the holes with 3/8" OD copper pipe/tubing two inches longer than the height of the corona motors rotor. twist the top clockwise and bottom counter clockwise until the top of the top bushing and the bottom of the bottom bushing are the same distance apart as the rotor length/height. replace the rotor with this new part. spin the part as if to lathe the circumference but sand it until there is an even grove cut through each tube on the surface of the new part. find a ring magnet axially polarized to cap the tops and bottoms of all the tubes, or place a magnet that fits the ID of the tubing into the ends of the tubes make sure it has good contact all the way around, no glues between the magnet and the copper. in essence the tubs become charged by the ions from the first anode and the magnet rotates the charge around the tube to charge the other edge... this makes a induction motor out of your corona motor
I could never manage to park my car within the lines but I used to tell everyone I am thinking outside the box. Your good at that too but I would hope you can park better than me!
This video reminds me how shockingly many people these days still believe the earth is FLAT.
Even though there is more than enough evidence without even going out into space, they seem bent on the idea that there is, in fact, no such thing as a spherical planet.
When you mentioned the changes in the stars one can see in the night sky, that reminded me of this absurdity.
One could use the flaps on a wind tower to run livers/links to a flywheel so we can try to double dip on our power generations - turbine and flywheel.
I would love to see a version of this with pendulums set up in a row like a large Newton's cradle (edited to point out pendulums swinging side to side as opposed to the usual Newton action).
I wonder what would happen if you were to put an electromagnet on either side of the pendulums swing so the coil would electrify the magnet, drawing the pendulum up and releasing it? If this increased the swing time indefinitely then could you place a coil up the pendulum to create indefinite energy?
I can't remember his name, he was a carpenter obsessed with time. He was the one who invented the balance wheel and won the prize that was offered. He was also British.
The more coils ormagnets the more friction so perhaps a "spring" needs to be wound from an outside source.
Well add a board to sit on and place the generator in the yard of a kindergarden then you will get energy for free from 09:30 to 13:00 for sure and as well in the afternoon. Put a lot padding around the cable and place it in a boxing gym = free (to harvest )energy in the evening 😁
I see the coil, but I didn't hear any mention of a magnet. Did I miss something?
perhaps a winding spring to capture the rotational energy of the a wind generator and translate it to controlled pendulum energy?
For a stationary system you could add a tiny amount of wind power to keep that going.
You are more using it as a battery not as a generator. You put energy in when you release it and a little is taken each pass over the coil to light the leds. If you were to time it you are slowing it down every time you go over the coil.
now i've got more things to try; you've opened my eyes with this video. love the frame!
Finding longitude should be easy for hikers on the Moon as long as they can see the Earth
Could you line up a whole bunch of them and time it so that it keeps the light lit?
I wonder if you could setup a piston on the top that uses low pressure steam to maintain the swing?
Obviously he`s not a flat earther... ;)
Are you saying an old town hall clock could be used to generate energy?
The flat earthers will be outraged GOOD.
Thank you Mr. Smith for your great content you provide to the public. I have a simple concept I think you may like. And hour glass filled with copper BBs flowing between two magnets. What are your thoughts sir?
Turning the hourglass would take more power than it creates or so the story goes.
So, my mind goes to a clock, of course.
Figure you could 3d print an approximation of a weight driven grandfather clock?
I figure crescent pedulum, several magnets, coils along the arc.
Youd have to raise the weights what? Every few days?
A gravity powered clockwork pendulum generator seems like it would tickle your steampunk soul.
That does seem like a viable way to solve the efficiency problems with gravity batteries
so, a new slogan: have movement, will generate! :)
Now you just have to figure out how to build one 1 mile high and WE'LL BE RICH!
At that height could also make a great static generator
Awesome indeed, no bearings, easy to build 👏🌟
3:57 he uses bearing.
That's a gorgeous globe 🌎
cooucco clock gravity cones
I like that globe
Pendulums have precession!? Ofcourse! I'm not sure what to do with that yet, but maybe that could come into play in a gyroscopic generator (for world-spin energy capture).. I'm not sure how yet.. Needs to be some breakthrough in gearing it up. Pendulum is an interesting battery, also.. but less power per swing due to speed reduction. My head is swimming with ideas after yours and Luke's videos today!
Rob, if you put a strong magnet on each side of the pendulum (at the right distance of course) wouldn't it keep on going indefinitely??🤔
The resistance of the magnetic field will swallow up the inertia of the pendulum a bit ahead of schedule, no? 🤔 Regardless, it's still a great application of the pendulum and will still produce quite a lot of electricity 👍 Very cool, and thanks for sharing Rob 🙌
Would be great to see Robs' take on the William Skinner Gravity machine from 1939.
The same effect is at play here. only in an entropic fashion.
That globe is a joke. Look for “Gleason's new standard map of the world : on the projection of J. S. Christopher, Modern College, Blackheath, England ; scientifically and practically correct ; as "it is."
Its amazing how apparently intelligent acting people are actually not. Or things are revealed to one, and it has nothing to do with being intelligent.
Anyway, I bet a bag of taters he thinks we are on a spinning ball.
I have given this a fair bit of thought. If you could add a wound up coil to provide the small bump of energy required to extend its swing time.
A small amount of energy to wind the spring, spring bumps the system with small amounts of energy at set intervals to maintain continuous motion.
Harvest as much as you can using physics to your benefit.
Love Robert's delight as the LED turns on.
Next---a capacitor!
Is it possible to use a simplified spring system to creat the same effect as a pendulum?
Amazing! A generator that can also tell you the time and is a spin detector 😏😂
this guy is so watchable i wish he was my teacher at school such a lovely talent
First! 😎
and the first time you have been first mate - so a double firstly - cheers
Add more to the bottom of the swinging pendulum so the leds get power over the whole stroke.
Could add a second pendulum that swings the opposite way to help provide constant power to the leds.
Would the 2 pendulum sync up even if started in opposing directions?
WHAT ABOUT RESONANCE
Thank you. 👍🐝🌞
Good idea Rob. I'm thinking the memory shape effect from a Nitinol spring can act like a natural actuator to keep pendulum motion swinging. Using the cooling surrounding environment being the wind, and eddy currents as heat when magnets passes the induction coil. Temperature difference between the two would make minute changes within the atomic structure of nitinol wire to spring back and forth, adding on more kinetic energy to the pendulum. Or dump some of the inductive spike collected from the swinging magnet into a capacitor and redistrbute some electric current back to the Nitinol wire. Possibilities are endless...
I don’t understand,but I like it.
The Nitinol wire can behave like a linear actuator. The Wind being the prime mover will Mechanically agitate the wired spring to go up,down,up,down adding more kinetic energy to your pendulum swinging motion which results with much greater torque. Since motion being relative to one another. While having the bottom middle coil to draw power to resistive loads. Having extra two coils on each side where the free weight as it swings meet at it highest point. Collect the extra electricity and direct it on each end of the nitinol wire. Which then will produce more force, more kinetic motion, more output force which leads to more swinging. Nitinol expands and retracts when inducing electric current is applied to it. Harnessing extra unused potential energy and transforming it into more kinetic energy
Pendulum power never thought of that
cool
