If I'm remembering correctly, my grandmother told me it ran for 24 days at which point I thought; why not 30? Basically, if you made a point to pull the chains up every two or three weeks, it would run until it wore out.

Seriously? Sorry, just joking. But ehm, this old technology is known by everyone, i would assume. I mean: Everyone knows a grandfather clock. And those who don't have been born in a place on earth where they never had any technology from the recent past. Tribes on islands still using bow and arrow, yes, i can imagine they would not know this technology. but somebody who is able to put a comment underneath a youtube video, i assume such a person does already know about Grandfather clocks. And every clock has a different running time. It depends on the clock, the length of the pendulum etc. If the clock has a gear train that can handle a pendulum that swings every second, then it may take a very long time before the weight reaches the end. 24 days may be possible. I dunno. Shorter pendulum will go faster. I got 2 of em. An oldy with a simple bell sounding every half hour and it strikes the hours. And i got a bigger one, with 3 weights. And in it it has the Westminster Chime, sounding every quarter of the hour. First quarter is obviously the first part of the melody. Second has 2 parts. Third 3 parts. And the strike of the hour has all 4 including the deep sounding bell sound indicating the hour. So 12 o clock it sounds 12 times. Warmink is the producer of that one. And if i am not mistaken the other one is from the same maker. Dutch clocks. Friese Staartklok is what the simple one is called. And the other one i believe is called Amsterdamse Staartklok. But i am not too sure about the last one being called Amsterdamse Staartklok. Anyway, they both also have a moonphase indicator. And the big one with the 3 weights has a handle so you can turn on or off the chime bit. So you can turn it off during sleeping time. And it resets itself when you turn it back on. The other one does not have that feature. It will chime, unless you take off the weight or block it from falling. Plus, when you take it off or block the weight from falling it will not keep up. And so, if you reinstall the weight, chances are that the chimes will not count the correct hour. Like say: its 3 o clock but it could chime 4 times, or 2 times. You have to reset it manually to get it back to the right order. Anyways, neat technology. Very old. And i would expect somebody who knows his or her way around the kitchen on the internet to already be familiar with this kind of technology. @@scotttovey

Remember the air Jordan tennis shoe? The one's where you pump the soles up so that you are walking on a cushion of air. They certainly did sound revolutionary to me at the time. Then one day, I happened to go to a museum that had a historical display. There was a sign that listed some past inventions. One of the items listed on that sign was a shoe that was made in the 1800's that had a pump up sole. Not so knew after all. People make assumptions all the time. Sometimes the assumption is accurate. Most of the time, the assumption is wrong. Here's one I recently learned that surprised me. The truism that human pregnancy lasts 9 months; is in fact, false. Given a normal pregnancy with a full gestation period, birth always occurs in the tenth month. Assuming that people know things is the quickest and easiest way to destroy a nation. Take the often used, don't be lazy rebuke of "Do your own research". That statement is predicated on the assumption that a person which is able to type words in a text box on a computer connected to the internet, also has the same search engine skills as the one claiming to have specialized knowledge of bad actors. Not only is that a bad assumption, it is an extremely selfish one. In order for one to find the given bit of knowledge that another person has, one must know two things; 1) The exact key words that were used to find that bit of knowledge. 2) The exact search engine that was used, and that search engine must be in the same state that it was in when the individual with the special knowledge found the special knowledge. I used Google for several years to do searches to learn PHP. At some point, having forgotten a specific way to do something, I went to Google and typed in the key words I remembered that brought up the information I needed. Two things had changed. 1) The PHP website had deleted a lot of the comments that users posted on the website for no apparent reason, thus the information that had previously existed, was no longer there. 2) The search results did not have as many links to the PHP website as it did before. Google changed their algorithm. I will often state the obvious for no other reason than the fact that very few people will. The end result of very few people stating the obvious is that the younger generation is now deceived into believing that poverty inducing socialism and communism, are more beneficial than wealth generating capitalism. I also do it because I at 62 years of age, I can look back on my life and I realize that there were a whole lot of "obvious" things that no one was willing to teach me when I was young, and I did not see those "obvious" things, until I heard them mentioned in KZread videos.

Weight is weight, and the benefit is that sand and water can be divided and moved in smaller portions, which increases the versatility of such a system. The real winner here in my opinion is water, because so many other means exist for moving it. Meaning your solar, wind, water generation, or any energy harvesting mechanism you think of, can move water for you. Add the assistance of a ram pump to move a portion of your water, and you really have some efficency.

I considered gravity from my family's grandfather clock with the long cylinder brass weights. But your video put it in a new perspective.

Don't forget that this doesn't need to be limited to generating electricity. It can also be used to physically move/power machinery. Like for drilling, cutting, milling, etc perhaps even for some novel forms of transporatation, connected to a transmission, drive shaft and axles.

And when there is too much energy being produced and nobody uses it, they use it to pump up the water to the lake above. And when they need more power, voila, they got the water in the top lake to produce the power they need. Btw, indeed, this is not Perpetual Motion.

But there are lots of 30 to 100 foot pumping stations that i feel could be augmented by modified archemedes screws. Actually spiral tubes of several meters in diameter and the lower end of this is on a floating barge so the depth of the dip is controlled so the top of the tubes are never filled to the overflow level. This might be able to lift significant amounts of water without and bypassing with much smaller motors to spin it.

Or maybe a series of massive ram pumps if there is sufficient head maybe

The rotating frame is ingenious but it seems like it would be simpler overall to have some kind of ratchet in the weight allowing it to be lifted without turning the screw - possibly something like the "half nuts" on a lathe feed screw, so you can pick the weight up and let it drop without turning the whole machine over

And imagine that being loaded by returning springs, laid flat at the base of a car and powered by gravity through thrust and force to recharge a battery for endless power with a wind up handle just in case.

Awesome idea. Just a little difficult and not very cheap if scaled up to store solar power for a small home though. Secondly there may be mechanical power losses due to the different directions of spin. But still awesome. Thanks.

I think that using a chain would make the design more accessible to DIY'ers as the worm gear shaft isn't easy to make and expensive to buy otherwise. Also there is very little room for rollers supporting the weight on the shaft, so that may require high precision small parts to minimize friction, further increasing complexity. The main challenge with a chain is to limit the descent rate without adding friction, other than the desirable resistance from a magnetic field passing through a coil. I'm sure a balance can be found with a very small sprocket for the chain driving a large stepper motor or custom-made generator. Unless it's meant to be operated by a child or elderly, I'd skip the whole crank system and manually rotate the frame as it's long enough to give plenty of leverage.

10:00, The work required to rotate the cage must, of course, be equal to or more than the work that can be got out of the falling weight. It would of course be a similarly person-powered device if buckets of water were lifted up the same height to fall through a turbine, or a spring was compressed. In all cases, it is human powered via an inefficient device. As I've said before, gravity is a rubbish accumulator for small scale devices like this. Equation for potential energy is mass (kg) x height (m) x g (9.81 m/s/s) Do the math. A ten tonne mass falling through about 37 metres 'releases' about 1 kWh. With most setups friction is huge, and times generator efficiency you will be lucky to get 20% out = 200 Watt-hours. To be of any use you need to suspend your entire house on a rope. Good luck with the plastic worm drive gearbox then! :) A good mass storage system is water pumped way uphill and run down through turbines when required, AKA pumped storage, at decent scale.

Sounds like a great plot point.

This was very cool to learn about

Here's a thought ok how to move an enormous amount of water quite easily: Take a large vessel. Connect large vessel to water below via pipe. Fill large vessel with steam. Seal off the vessel. At which point the steam condenses into water. Creating a vacuum, drawing water into the vessel against the force of gravity. The only energy needed, is enough to create the steam to fill the tank. Ps. The same thing can be done by igniting hydrogen and oxygen into steam, then liquid water.

The liquid is emptied at the bottom and then reset. Making the reset process relatively simple, lighter and safer, removing mechanical stress from the system. This would allow the 'recharging' to be done slowly as the container is re-filled, via a small pump with the same water (Liquid), by a smaller intermittent energy source. (Wind, solar and so on). Obviously a minimum of two systems would be required for a continuous power source.

If places like Niagara Falls and the Hoover Dam were fitted with gravity power recovery systems that utilized a much greater percentage of the water "flow", such as water wheels of such quantity and capacity to handle the volume..., then much of America's energy could be captured for "free". [Fuel price free, not building, operating, repair, etc]. The screws/propellers/impellers currently used let a lot of water to pass, andat the water output the water still has much energy....

Wow i want to make wind energy way using paint roller 😂😂with weights as well ;!

Nice idea! _PS small audio quality problems on new content_

Working on it!

Love the video Robert!

Thanks!

That's a very petty opener to this topic.

To produce enough energy to heat a home in a emergency is going to take alot more then a small device that just light up bulbs. Better off with a small rocket stove.

very cool

Now what about doing a spring wound motor like in the old Victrola?

That toy store looks a lot bigger on the inside.

The is a toy store in Helensburgh which also feels bigger on the inside than you expect - over 500 miles away...

I'd like to see that combined with a spring. How much energy could be stored in such a mechanical battery?

if that falling weight could also tighten a spring as it fell, couldn't the cage holding the weight be made to flip itself over without the crank? awesome as always!

Then the weight would only fall to an equilibrium with the tension of the spring. Good engineering might be able to get it to flip a few times but each flip cycle would be shorter and eventually it would stop. You would also have to input enough energy to get the spring to stretch which robs energy from the genny. Better off just putting all the energy into the genny.

@@flyingsodwai1382 ok. I'm not an engineer, but love the possibilites of these physic exercises.

Energy was not _given_ the apple (merely _loaned_ ) and it must return with interest (it is a s lave) it was forced to relocate (at a cost to the apple and its pips) that must fall down a gravity hill (more like a wall they can never climb) before it is more and more quickly eaten alive by maggots or ultimately turned to a rich juice and consumed while its pips are spat out

I really enjoyed this video, Rob. Thanks for posting! Do you have the URL for the video of the Technological University of the Philippines portable gravity power generator? I'd like to watch that as well.

Thank you, Robert, the Device is realy fascinating, is there a link to the original video as well?

I wonder if you put a motor that will crank another C G and so on, in a circle so that the last C G cranks the first one again starting the processes all over again and each one gives a little bit of energy to power lights or what ever?

Robert,are you aware of The Primer Fields by David LaPoint. If not,i think it would interest you.Thank you,great channel.

Could all this be incorporated into a wind turbine that could turn the crank handle? For home use.

Pardon me, as I am not an engineer by any means, but I have some thoughts on the last invention shown. What are ways that the power could last longer? What are some ways that it could produce more power? What would making the weight heavier provide? Would a smaller threading be better because of more travel distance? Would this be possible with gears?

Grest topic!. Looks like YT isn't recommending your vids anymore to me?

Hey Robert, did you think of making the screw on your lathe? I assume so😅

Gravity storage is my end game. I love the fact that it's storage time is infinitely lossless. I have questions about the mechanical efficiency though. IS a worm gear running a genny physically more efficient than a chain or rope turning a pulley for a genny? I've no physics training really but it seems friction losses would be more in a worm gear set up.

It depends on the screw and nut combination. In CNC technology, one of the things that is designed to eliminate is backlash. Backlash is slack in the system that allows play within the nut and screw union. There are two ways to eliminate backlash. 1) Use the screw to create threads in a plastic nut. 2) Design the screw and nut in such close tolerances that there is no slack. In a belt or chain system, you would use an idler pulley to remove the slack in the system. The key is to know what you are engineering for. In this setup the worm gear appears to be limiting the weight's speed of decent, but that may be caused by the electrical generation itself. Whereas a belt or chain will have no ability to limit descent.

Instead if all the mechanical bits, is it possible or reasonable to put the magnets in the weight, and the coils around the outside, so you just drop the magnets through a tube of coils, directly converting the kinetic energy into electrical energy?

I wonder if you could lift something really heavy to store energy. E.g lift your house up a few metres to store solar power in the day and have it drop back down during the night. You'd have a super geared down motor. Admittedly the house would need to be designed from scratch for this and would pose some architectural and engineering issues to make it possible to get in and out at varying heights. Problem is if you do the math it's not a good store of energy. E.g. lifting 50,000 kg 10m in Earth gravity (9.81m/s/s) is 50000*10*9=4.9MJ. Which is only 1.36 kWh. Meanwhile a 12V 180Ah battery is 12*180=2160 Wh or 2.16 kWh. So the numbers don't really add up unless you have enormous masses or enormous heights. Or both if you have pumped water energy storage.

Thanks for the exact numbers and comparison, I'm currently searching a plot of land for an off-grid cabin, and I'm planning to do pretty much what you've described by using heavy things on the property (=large compost, watertank, small greenhouse, toolshed...). I know that the energy density is absolutely terrible compared to modern batteries, but since that won't be the only thing I'll have supplying energy, it's quite cost-effective, material-friendly and relatively easy to build, I think it's well worth doing. I will have other systems also (like wind and solar), but hopefully I could use gravity and weight for lightning some of the time.

Per minute cranked, how many minutes of light does it produce? Joules in vs joules out ~25%? Link to the vid seems to be missing.
