i would have trouble believing that the buoyancy from the canisters could overcome the various instances of friction/inertia at work in that system. Especially if you wanted it to produce an excess amount of energy. That pulley would need to be frictionless, and that is simply impossible.

problem, friction...?

not to mention what kind of strings you would have to pull in order to get a functional donut seal that doesn't leak yet provides no friction when the canisters enter.

Surely you could design enough buoyancy to overcome the friction though right?

Don't forget the friction cause by passing through the donut seal. And the negative pressure exerted by the water on the seal would add to the difficulty of pushing something through.

When the canister goes through the "donut seal" it must displace (push up) enough water to make room for itself. This consumes energy. The canister rising can be viewed as the water it raised falling back down, so the entire process boils down to lifting up a volume of water, then putting it down again.

If you're at a loss, you're not good at slamming free energy. Think about why things are buoyant, and where that energy comes from.

Wouldn't the "pushed up" water really just be the top canister leaving the water though? Then you end up with the water level not rising at all.

So close! I'm not quite convinced yet that it can't work.

Friction is never the only reason why a perpetual motion machine of the first kind will not work.

since it's a gif, we can see that the machine doesn't move at all, so it clearly doesn't work.

I figured it out! Thanks to "think about where buoyancy comes from"

An outside force is required on the bottom canister until the bottom of the bottom canister is in the water. Imagine if there were an indention (canister shaped) in the bottom of your fish tank - no buoyancy and only water pressure pushing down.

Thank you good sir.

yes but wouldn't the canister in the middle of the water region pull the bottom canister up until water can flow underneath it as well? then the process repeats.

lulz

The energy it takes to push the canisters up into the water is more than the energy that they produce when rising through the water.

The water that is being pushed up, is a column of water the entire depth of the tank. You can't push up that entire column of water using the buoyancy of a float near the top.

but you could design it to have 5 floats in the water at any time, so the force of the buoyancy is more.

Energy required to go through donut seal = energy gained by buoyancy, because as much water must be displaced upward as the float enters the tube as will provide lift as the float goes up.

I've seen this posted over and over but I've still never seen anyone even attempt to explain that fucking magic donut seal.

Its magic i dont have to explain shit

←I help you guys.
