There is no energy problem. Same with there being no population problem, climate problem, and food problem. Those things are not real. They are just used to fear monger you and keep you under control.

The only actual problem is logistics. The energy needs to be better used. The population needs to be spread out more. The climate needs to even out. The food needs to be distributed properly. See, all problems with logistics.

No it doesn't, the liquid mass in the ocean creates forces which are consistently eroding the rock underneath it and could pose as an energy source.

Yes, >>9539009 is talking somewhat sense, but the ocean is not static. The ocean moves constantly. If you had my pressure plate you could create constant energy from the kinetic force.

And it's on the BOTTOM OF THE OCEAN. Even a small plate would receive a vast amount of kinetic energy.

I don't see the issue here.

it doesnt get vast amounts of "kinetic energy" since kietic energy is stored in movement. does it get high speeds ? no.
what you mean is pressure.
and the pressure is only enough to push water at the same height as it was before (same gravitational potential) throught a tube, not to the house you have drawn.
Also force !== energy. yes there acts a force on the pad due to pressure. but since there is a counterforce just as high (earth inertia: mass is high enough so that it doesnt move), nothing happens, except for the thing being pushed against earth.

For one, pressure is not a Newtonian Force and creates no energy from a plate, that is also pressurized at the depth level of the water surrounding it. Secondly, Pressure is only density....meaning it is Exerting force in ALL directions, not just down; in the same note, the pressure of all matter at a certain Atmospheric Bar, no matter if it is water, steel, plastic, or a baby fart, is going to exert equal pressure back on the surrounding matter. Every action has an equal and opposite reaction.

The water isn't moving in a closed loop, though. It's going entirely from a potential source to a sink, and the potential drop is captured by turbines.
Water is replaced at the start of the river by energy from the sun. If you were to haul it back up with another turbine or otherwise, you would at best break even, but probably would go in the red

You are literally just arguing semantics you donut. Every single energy source on the planet is due to the sun if you go back far enough. We categorize power transformations by what we actually have to deal with and design for. You don't size a fucking dam based on solar considerations, you size it based on height and flow considerations, which, spoiler alert, deal with gravity.

Exactly. You accept that you have a certain flow rate and drop height (due to how rivers work) which is not present in >>9538985
Just like how you can generate energy with a heat engine when you accept that you have fuel and shit, even though engines only "lose energy"

It would have be made using a hydraulic motor. You would basically leave a hole in the ocean floor and let enough water through to turn a turbine and power a generator.

The problems begin when you try:

1: Building something like that underneath the ocean without it collapsing.

2: Allowing that amount of to water to cycle back into the ocean without losing more energy than you've created.

3. Ecological implications like disturbing ocean habitats and like if a big fish gets stuck in ur turbine.

It works if u have a big enough pad then the surface area of the pad x the weight of the lake x change in barometric pressure is a transfer of energy to the pad that can feed a flywheel of some sort

>> No.9545533

>>9545426
But the water would only do the work to push the pad once.
And that's not counting the fact that gravity is already going to do some of the work anyway.
So on top of that you have to have something in the system that would stop the plate from being pulled down by gravity to begin with.
The flywheel is unnecessary given that you're gonna have energy loses before sending it to a power station

It would probably work. I don't think it can deliver a big enough amount of energy to justify constructing it though. There are other easier ways to get energy out of a temperature difference, like a heat pump. I don't think sea water has that big of a difference between surface and deep water though, there are better options for getting energy from the sun.

Force of gravity is conservative.
All you get is pressure as the bottom, to bring it back up would take the same energy it took to push it down the same distance.
Then your net Work cancels
