Ratchets are noisy. Have you considered a sprag clutch? They make them in very convenient ball-bearing style sizes and packages.

The good news is you don't ever have to worry about branches or the trunk growing to be longer and making your cables not long enough. Trees don't grow up from the ground, and branches don't grow out from the trunk. Trees grow from the many tips of branches, and from the top of the trunk. They grow outwards by adding new layers of wood beneath the bark. So if you place an anchor of some sort in a branch/trunk, the tree will gradually grow around that anchor, but the anchor will never move on the tree.

the ratchet mechanism would mean that you are only collecting energy when it moves one way. It works, but I would have probably fixed the reciprocating issue with a bridge rectifier on the output. Though this might be better, as it lets you reach higher velocity and likely convert the energy more efficiently. SO I don't know which would have better output.

Have a look at a one way bearing. It would simplify the ratchet system and make it 100% print in place.

This system would work well but waste half the energie

Couple ideas, one if you can do this strategically where you are simultaneously bending, or training, the tree limbs to shape the tree in an efficient manner to further catch wind, that could be helpful over time; and two, if you could connect a mini generator to the blue ratchet part, you can capture even more energy.

We got water based weaponry before GTA 6

if you made the ice chamber conductive, but then isolated that area, you could discharge a capacitor through it to flash melt only the outside ice. This would give you an infinite hold time and very short lock time. It would be difficult to do all of that and ALSO have a short freeze time though. There aren't many materials that conduct heat well, but don't conduct electricity. Looking at the list of available materials that fit the bill, stuff like Boron Nitride and Beryllium Oxide...probably not in your budget range, but that would be a really cool setup. Perhaps a thin teflon coating would work? or a layer of kapton tape?

Don't use feet wtf

That is amazing what you have built. Are you planning on releasing the plans and schematics? I’m a mechanical engineer and I would love a crack at it.

Now make it more powerful

This is such an excellent idea! Thank you so much for sharing. I'm curious about using a gravity battery for the energy storage. I would think that less energy would be lost to friction vs a flywheel.

It's an ice pellet gun/air rifle

The reason the CIA has an interest is because their heart attack gun uses an ice projectile to encapsulate the poison it uses.

This is a fun idea. I'm not sure if anyone has mentioned this already, but similar to the branch growth issue, if a band is placed around a tree and the tree keeps growing, the band can cut through the bark all the way around, cutting off the supply channels and killing the tree. For this reason, it's important not to leave things tied around trees for extended periods. This can also kill distinct branches and should be considered for all attachment methods.

Awesome project and the video does a fantastic job of explaining the build! Standing next to the PVC pipe while pressure testing it was wild... Maybe put a sheet of plywood or 3 between you and the potential pipe bomb next time.

Very good ideas. Consider mounting this to vertical poles with sails or pedal at the ends, each attached to its own drive cable. The poles must be flexible like pole vaulting poles, or stiff poles with tight spring coils at the optimal flex points. The sails or pedals can be designed to have optimal wind resistance, and the length can vary according to wind conditions in different areas. In this ways you wouldn't be dependent on the location of trees, and it could be mounted in a city or urban environment. Even on top of high-rise buildings. Good luck. Love your approach ❤

Os pêndulos de relógios antigos, ⏰️ pode ser uma boa ideia pra mover esse gerador, pois os relógios giram 24 horas com uma cargar em suas molas

that's insane, a couple hundred dollars for all of that. either someone is getting paid enough or it's coming from china.

You should have it store power in a spring with a clutch that allows it to spin when released. So it stores up power in the heavy spring by way of your ratchet system. Then it can be released spinning the fly wheel. Maybe a gear box that can switch once the spring is released that allows that ratchet system to put energy into the system at a constant rate to prolong the rotation of the fly wheel. Or maybe a gravity storage system might be easier. Make your ratchet system lift a heavy load that us attached to a gear box with the fly wheel. Once released it can give you constant power for the duration of the falling weight.

2:30 I swear it looks like you're driving IN the screw counter clockwise. Probably due to shutter speed and lighting, but still weird.

Branches move with different speed. If you put all ratchets to one shaft only the fastest one will be able to output the power. All other would spin slower. To harnest power from all of them you need to add some mechanism to combine power of two schafts into one, like differential drive in car.

So mabye to help with the trees growing you could attach them with hooks that give in some way and hopefully fall down and rehook themselves somewhere else

A water gun shoots water and ice is just freezed water so yes it counts as a water gun

Probably got the CIAs attention cause I bet the magic bullet that killed JFK was an ice bullet.

I just wonder where you got that numbers. If I see correctly you use 8 pieces of 36mm bore cylinder aprox 25cm long. So you got aproximately 10kg of force on each cylinder or total 80kg of force. So you have aproximate 800 N force over 0.25 meter. That give storage capacity of 200 Joules. And you claim that you got 628J electric power from 200J available storage space? Or I miss something.

dude's chainsmoking ciggies while hes inventing new weapons you earned my sub lol

That is so cool that you've listened to the comments section and managed to find a valuable info out of that. This fact itself is inspiring! Keep it up. Good job!

Can't you just reverse drive the peltier?

My idea for consistent power output is to work the system like a grandfather clock. The power from the branches winds up a counterweight which is consistently pulling across a gear set which is driving the generator. Wintergarten had to solve a similar problem with consistent power output

Het is an absolute lekker project :D

Litterally thought of doing this a few months ago happy to see someone beat me to it and it's beyond a proof of concept

Scrap the idea of the trees using moving water with a constant consistency in bobbing instead of a wheel and stop explaining yourself to people in comments take what is useful and dont waste on anything that doesnt serve you youkk save so much more time for inventing good luck bud youre doing great youre just getting started

I love everything about this. Keep going!

Just attach a spring to the end of the rope. Allows you to convert the movement to linear motion directly as the rope will move back and forth. Less friction, simpler

Great improvements! I can't wait to see the next phase being tested on a tree.

This is very interesting. I have thought about similar ideas to make a device that tree cutters could shoot to the top of trees that are to be cut down, such that a falling tree could be used to generate electricity from the potential stored in a large tree to be felled. For that matter store the energy of large branches as they fall after being cut.

Ga zo door! Ik droomde een paar dagen geleden toevallig hierover en besloot je vorige filmpje nog eens te bekijken. Wat leuk om te zien dat je ermee verder gaat! Ik vraag me af of je het energieverlies en de slijtage in de ratchet misschien kunt verminderen door een smeermiddel eraan toe te voegen? Vooral de slijtage lijkt mij iets om op te letten bij zo’n systeem dat de hele dag werkt en duurzaamheid hoog in het vaandel heeft staan. Lekker bezig in ieder geval!

That ratcheting multi-branch setup looks really slick. Neat!

when i readed the title of the first video i thought to make energy with the growth of the tree.

would love to know where the CIA comes into place, calling this partially an clickbait title. Doubt CIA even cares about this

you could use the eneergy from the bendind branches in both directons, may be adding 1 more trincket and and a gear to change rotating direction

Weights hanging from a tree blowing in the wind? They will need to be encased in some sort of tubing assembly - and probably lubricated to mitigate friction.

Can you try it on a selecon gel so we can see how deep it can penetrate.

That is the reason to subscribe :)

What about also using the "return" motion of the branch to produce power? Use another ratchet mechanism in the other direction on another shaft, then mesh it with the primary shaft using regular gears so it will keep spinning in the same direction. Another way would be to mount it on the same shaft and using a planetary gears inverter in order to reverse the movement of the "return stroke". The down side of both solutions would be the increased friction due to extra gears, but maybe using movements in both direction can compensate, and even overpower it...?

Okey lets straightaway get to my observation 1. Right now for a single branch movement the energy is collected only in one direction, it would be effecient to collect energy using the motion of branches from both the side 2. if you have seen in the bicycle how free the back tire rotates doesn't get effected by the backword peddling in the same way imagine the tire as the flywheel where all the branches are exerting forces on the flywheel which is very freely rotating using baring. You are really out of the box thinker, were unique way to generate electricity KEEP IT UP

The flywheel might be better after a gearbox that speeds up the rotation

One quick thought on the ratchet mechanism, I feel like only harvesting energy when the branch moves in a single direction might be a bad idea, as it prevents the kind of "resonance" that might lead to more motion? Just a thought.

Interesting concept. I can't wait to see it in action!
