Is it a miracle? Infinite energy using gravity as a source.

Sounds too good to be true.

>> No.11938927

>>11938923

Nope. Doesn't work.

>> No.11938928

Gravity is clearly something that is yet not understood.

>> No.11938943

>>11938928
Then learn it.

>> No.11938945

What do you mean, "using gravity"? Like, dropping heavy stuff and recuperating the energy? You would have to lift it first.
Give us a concept, a very basic idea of how you propose we harness gravity.

>> No.11938957

>>11938945
I think the idea is that if we were able to manipulate gravity, we could force objects to "fall" in any direction we want.
I imagine there's probably some catch that prevents it from being a source of infinite energy.

This actually what is done by hydroeletric power plants.

However the point is: energy is being used, where does it come from? How does it work?

>> No.11938970

>>11938959
Just use black holes duh

>> No.11938978

>>11938957
Yes you can manipulate gravity by moving mass. This requires moving more mass than would be attracted towards it, so no energy can be gained. You can gain energy by exploring gravitational potential which already exists.

>> No.11938981

>>11938978

The point is that by logic this is impossible, something is losing energy don't you agree?

The energy that creates the water vapor that then condenses into the rain that feeds hydroelectric dams is provided by the sun.

The fuck you talking about bro it's the water's movement that generates energy and it's caused by gravity.

>> No.11939058

>>11939003
Yeah but the water still needs to evaporate at some point, otherwise you'd have no water flowing to your barrage. That's the cycle of water, or whatever Americans call it. That's what gives the water its potential energy.

You seem to have no idea about what energy is and how it works.

No you're just tranfering energie from one body to an auther one.

gravity in the sun creates fusion which heats the water on earth

>> No.11942924

>>11941242
Fuck, you got me.

>> No.11942942

>>11941242
That fusion process is not free energy, it spends fuel (hydrogen) that eventually gets exhausted as the star ends its main sequence life cycle.
So the sun is basically spending the energy stored in hydrogen.

There's so much hydrogen in space that you could consider it infinite, but it's still not free energy.

>> No.11943727

>>11938923
Look the closest thing we have of "free energy" is the sun, it is literally the only reason any life is possible in this earth, if there is a god it would be the sun.

>> No.11943733

>>11942942
But it is, do you really think 4 billion years isn't infinite for us?
