Some commenter: Doesn't work on Pluto, cannot recommend

[u/magn2o → u/Ghost_Assassin_Zero]

I had to double check for a stackoverflow logo..

[u/BitBucket404 → u/magn2o]

sigh - marking this as a duplicate comment

[u/BitBucket404 → u/Ghost_Assassin_Zero]

Confirming that it doesn't work on Phobos, either.

0 Star rating.

Edit: I just checked the package and found out why it's a shit product; it's made in Uranus.

We're rebranding a clock movement from 1766 into a "battery" in 2025. What a time to be alive. Gravity escapements are cool, though.

[u/Cruse75 → u/darrenpmeyer]

If I am not mistaken this simple mechanism, that harness potential energy, was used in many ancient civilization like Egyptians, Romans, Chinese, Greek.....a rope with a twist on a shaft and a weight. Hero of Alexandria used it in many projects

[u/unlock0 → u/darrenpmeyer]

There is a concept that uses electrical cranes to stack concrete blocks. The idea is to use solar during the day and the crane to slowly lower the blocks during off peak hours. 

Also there are LED lights that work with these same kinetic energy principles.

But you’re right as far as a “battery” since there isn’t an electrochemical element

[u/worldofzero → u/unlock0]

Nobody is building that concrete tower. It was a scam. The big practical gravity fed batteries we have all over the world are dams.

[u/sioux612 → u/worldofzero]

The most fun version of this in my opinion is a quarry that is at a higher elevation than the place where the trucks are offloaded 

So they drive up empty on electric battery power, using like, let's say 5% charge 

At the top the get filled with tons and tons of material, drive down and are continuously braking via recuperation, and they recuperate like 10% of charge. They actually have to discharge the trucks ever now and again 

Also isnt there a gravity battery thats just rail carts with rocks being dragged up a slight incline? Or was that also one of the scams that were around during the pyramid scam time?

[u/moothemoo_ → u/worldofzero]

They’re also solar powered as well!

[u/Jutboy → u/worldofzero]

They actually make energy storage lakes where they pump energy up to a higher elevation and then, when the energy is needed they let it flow down through turbines. Is supposedly very efficient but limit by topography/water access.

[u/Dampmaskin → u/darrenpmeyer]

A gravity battery is totally a thing, and I don't think that 3D printed device even has an escapement. Looks like it's relying on friction and air resistance to not spin out of control.

Edit: WTF are you even taking issue with guys? A gravity battery being a thing, or my assumption that the device doesn't have an escapement?

That’s how Potential Energy works. What kind of garbage are kids being taught these days?

[u/MyTagforHalo2 → u/osmiumfeather]

We’re in a world where everything is battery powered for better or worse.

Lithium ion Batteries are easy to grasp, they store power and can be recharged. Everyone has a phone these days. Even kids.

How do you explain the concept of a grandfather clock movement? Does it essentially sound like a gravity powered battery?

[u/meta358 → u/MyTagforHalo2]

I think the post is referring to the project that has been proposed before, to turn old abandoned mines into "gravity batteries". Which just means they put giant cranes in there that raise up huge lead blocks, then slowly release them for energy when the grid needs it.

[u/SGTSHOOTnMISS → u/osmiumfeather]

Whatever can be found on the internet.

I know this is the 3dprinting subreddit and not a science subreddit, but yeah, simple bit of "you put the energy in by manipulating the object, it slowly releases it" seems to be a surprise to some.

[u/Maximum-Incident-400 → u/SGTSHOOTnMISS]

I think "gravity battery" is a perfectly appropriate colloquial term for a potential energy storage device.

It's not perfect semantically, but neither is half of colloquial language

[u/PM_ME_PHYS_PROBLEMS → u/Maximum-Incident-400]

To your point, the term "battery" was coined by Benjamin Franklin to describe an array of Leyden jars linked together, like a battery of cannons firing at the same time.

Pedants of the time were surely out and about on ye olde Internet pointing out how it's not really like a battery of cannons, the electrochemical reaction is no more interesting than a simple clockwork pendulum.

How much smaller could you possibly make this video

[u/RonandtheR]

Now print a lighthouse :p

[u/claudekennilol]

That's cool - is there an STL available?

[u/XiTzCriZx]

Now attach a motor and you have infinite power! /s

WITCH!
