Is there proof gravity can not be a energy source?

[Omnibus]

Can you prove what you say? Can you prove gravity does not make things move? And if gravity makes things move it is a source of energy.

I've proved it already -- put an apple on your kitchen table and let it stay there. Gravity acts on it and yet it doesn't move, correct? Energy only appears when there's also displacement under the action of gravity. So, to have energy you have to have two things -- displacement and force (gravity). Only gravity isn't enough to have energy. Gravity is not energy and therefore cannot be a source of energy.

The enormous energy of Niagara Falls has long been recognized as a great source of hydroelectric power.    Gravity can be leveraged and used to create electrical power realizing the stored potential energy of water behind a dam.   So to answer the question, there is proof that gravity is being used as an energy source.   The rest of the discussion is just a matter of semantics.   The actual real source of the energy comes from our sun and the water cycle.

Do you not recognize in your Niagara falls example the two elements -- force (gravity) and displacement -- I pointed out to you, which characterize energy? Gravity acting on still water, even if that water stands still at a height thus having potential energy, does no work. For gravity to do work conditions must be ensured for the second element -- displacement -- to come into play. Gravity itself isn't enough to produce energy. Gravity isn't energy. This isn't semantics but is the essence of this problem.

i have been a daily visitor of this forum for several years and this is
my 1st time to reply to any topic. I really like the way that you explained that it might take at least 2 different totally separate systems in conjunction to make a gravity engine self sustaining.

Since everything starts as an idea 1st, I am still wondering ,why out of all the ideas that are discussed daily, there has never been one reference to a practical idea that I have had for some time now.

With most ideas that I have seen there is always some problem to
overcome having to do with friction,levers,ramps,shifting weights,and etc.

My idea has to do with continuous gravitational fuel with a small amount of energy needed to return the fuel to its starting point.

My reason for replying to you is that I think you are the most fair minded on the forum.I think now is the time to put this idea into a real world project.If interested, please email me cdglobalprojects@gmail.com

What gravitational fuel? It was explained that gravity is not energy and therefore cannot constitute fuel to be spent as energy supply. That is nonsense and should be nipped in the bud from your first posting.
