Gravity motor for gravity microgenerator (battery) or maybe a clock project for children. 

In the future, we may need like that a gravity engine in several applications where only need a small amount of energy.

This motor can give a larger energy package at specified times and without a hitch. Anyone who hasn't tried it might think this is a simple task, but it's not. For example, if I want over more than 24 hours only weight of 1Kg let down 2 meter long, it is not an easy task at all. This is the first experiment and the first version with this method, so there is not much data and experience yet but I see an opportunity in it, that's why I'm sharing it.

Actually I was thinking about a clock for children and I thus I made it up this structure.

So the other application could perhaps be a lesson project for children. 

Those who love science also love classes. The clock is one of the earliest machines developed by man and one of his most important inventions. I think building a clock is a great science project for anyone. However, a watch is much more complicated and much more difficult to make than the layman might think. In fact, every watch is a masterpiece! My goal was to make a simple clock that doesn't go astray for more than half an hour a day, works for at least a day, and has such a simple and transparent structure that a 10-12-year-old child can easily understand its operation and even build one . Even a medieval person would have been happy with such a structure. The first challenge in the watch is to be able to operate a gravity engine and system for more than 24 hours at all. This is already a big challenge, namely because of the Square–cube law. This roughly means that every structure has a certain ideal size. What we can do well on a small scale, we may not be able to do well on a large scale, or vice versa, and in relation to the ideal size, we cannot do it well on a much larger or smaller scale. This is because as the size of the whole system changes, the characteristics of the parts change to different degrees. If a child, or an adult like me who is not too smart, and not patient, wants to make a watch, it is about possible for him if his clock can only run for 12 hours without stopping. I think that a clock can be called a clock if it works for at least 24 hours and is no more inaccurate than half an hour in the one day. That's about all the early hours knew. My next thought was to do more hours and run the motors in sequence or alternately. However, I haven't found a mechanism that is sufficiently simple to accomplish this. The other possibility is some kind of escaping structure that has a slower or finer resolution than solutions based on simple friction or pendulum. I first tried a water clock, but it's unbelievable that it knows exactly the same as traditional mechanical escapement mechanisms, that is, the conclusion is that approx. 12-hour operation is easy to achieve, but 24-hour operation requires the creation of a masterpiece. The best method we can use is the pulley. With the water clock, the surface tension of the water is the obstacle. The solution seems to be to make not a water clock, not an hourglass, but an air clock, in a way that is as simple as a water clock. All mechanical clocks change speed in response to ambient temperature. They were able to reduce this with pendulum clocks and various inventions. Then the accuracy improved due to better escapement mechanisms, as well as miniaturization and more precise workmanship. The viscosity of air also changes with the air (unlike that of water, it increases as a result of warming), but I do not yet know how much this difference means on a daily basis in the case of such a watch. The temperature in the apartment is pretty much constant anyway, so maybe this wouldn't be such a big problem. Since this clock is based on friction and not a pendulum, it is definitely not that accurate. As the temperature changes, not only the size of the materials changes, but also the friction, but maybe that wouldn't be a problem either. However, when we use gears, the torque passing through the gears will also constantly change, due to the inaccuracy of the gear and the fact that the teeth press against each other at different distances from the shaft. So a clock based on friction is even more inaccurate in smaller time units than in larger ones, where these differences balance each other out and give an average. The unevenness of the gear system can be corrected by using several motors and/or gears in parallel. Of course, if we don't achieve medieval precision, this gravity engine will still fulfill the challenge of working for more than 24 hours much more reliably, easily and simply, and maybe it can be the basis of a clock or something else, for example a gravity microgenerator (battery).




The easiest way is to not use gears, and then we can achieve a more even operation.
There are 86400 seconds in 24 hours. If a 3 mm diameter motorcycle spoke is used as the axle, then the weight wrapped around it in one revolution is approx. It will descend 10 mm. If we drop the weight from a height of two meters, we have the possibility of 200 revolutions. If we lower the weight with a snail, it is 400. If we divide 86400 by 400, we get 216. In other words, the clock needs to make one revolution in at least this number of seconds in order to be able to operate it 24 hours a day. That's 3.6 minutes. If we set our clock to four minutes, it will be able to run 24 hours without gears.

If we set the revolution to 4 minutes, then it is 240 seconds. If we want the hour hand to turn once in 12 hours, that means that there are 43,200 seconds in 12 hours. If I divide 43200 by 240, I get 180. This is quite a lot, i.e. the number of revolutions has to be reduced this many times so that the pointer turns twice in 24 hours. This is quite a lot, but slowing down the fall is not the same as speeding it up, because it interferes much less with the continuity of the clock. This can already be solved with a gear, or a more special gear, or perhaps in another way, but more on that later.


Some of my earlier ideas:

It's a great honor to me that Nguyen Duc Thang made an animation for it! Here is the youtube channel: https://www.youtube.com/@thang010146/videos

And the animation:


One of the disadvantages of this arrangement may be that the bar has to be raised, but of course We can it leveled. So next idea:




My first simple water clock ideas:

Idea 1:


That was my first idea. Relatively simple clock escapement. You need two to work smoothly, and they have to be placed with a 90 degree phase shift even on one axis. I drew it on two axes to make it easier to understand. At the same time, the disadvantage is that the system is open, and I would have liked something simpler mechanically.

My goal was to make a simple clock that doesn't go wrong by more than half an hour a day, works for at least a day, and has such a simple and transparent structure that for a 10-12-year-old child to understand easy its operation and even can build one.

Idea 2:




This is quite simple clock escapement, I tried it without gluing it from transparent plastic pipes. At first version it got stuck because the water was dirty, but by the second it was working fine. With this also children can easily build  a medieval clock!

My videos about this experiment were deleted by Youtube and Rumble. Unfortunately, there is no video sharing site that is not under the tyranny of the anti-white global Jews. In any case, you can watch the experiment here:

other idea:



In this solution, I connect tanks with a capillary tube. As a result of the increase in temperature, the liquid passes through the capillary tube faster, which would make the clock run faster. At the same time, the volume of the liquid with Newtonian viscosity increases due to the higher temperature, and a larger part of the liquid moves further from the center of mass, so the wheel rotary will be slower. This is how the inaccuracy caused by temperature changes can be handled.


Tibsim More Accurate water clock:

There are two water clocks, one rotates the hour hand and the other the dial in the same direction. The watch with a dial is designed to respond more strongly to temperature changes.


Idea 3:

Further development:

Since this machine did a beautifull work, I thought why not improve it further. Unfortunately, the viscosity of water changes with temperature. If the temperature is higher, the water flows more easily and the clock may speed up. 

https://en.wikipedia.org/wiki/Water_clock#cite_note-51

I am looking for the simplest solution for accuracy. The viscosity of air changes to a greater extent (about fivefold), but oppositely, than that of water, to changes in temperature. Water and air clocks together building can balance each other.

The my gears:



An easy-to-design and low-friction gear. If small bearings are used for small gears, the friction will be even smaller.  Use a 0.3 mm gap between the teeth... The (cylinders) teeth must be at least 5 mm in diameter.
