Is there proof gravity can not be a energy source?
« on: February 07, 2011, 07:25:10 PM »
The purpose of this post is to discuss weather or not there is proof gravity can not be used as a energy source.

Gravity cannot be used as an energy source because gravity isn't energy to begin with. It's like asking to discuss weather or not there is proof that apples can not be considered oranges or better yet that apples cannot be considered a railroad.

Gravity makes things move. Gasoline in a internal combustion engine makes things move. Gasoline is a form of energy. Because gravity has the ability to make things move it to is a form of energy.

How is gravity acting on an apple, sitting still on a table, making it move?

The earth spins, things on the earth are held on earth by gravity.
Without the work gravity does on things on earth, things on earth would fly off in a tangent.

It is prooven without doubt that gravity alone cannot be used as a energy source.

Gravity doesn't do work on things that stand still on earth. Gravity doesn't do work on an apple standing still on a table.

Gravity alone cannot be an energy source not because it has been proven without a doubt that it cannot do so. Nothing like this needs to be proven at all. Simply, gravity isn't energy. Period.

Work are done ONLY if a gravitional force are able to move an object into another potential energy level.
Work are also ONLY done if an object has changed its position in line with the gravitional field. Moving an object from A to B, angular to a gravitional field, does in sum not require work because the altitude are not changed. What work we spent to accelerate the object are taken back when deaccelerating it into a stop at point B.

Like I said, there's no need to prove apples are not a railroad. So, no need to talk about that.

Here is a proof you can do on your desktop:
Place a pencil on your desktop. Look at it for a very long time. Does it move? Did it suddenly jump upon a shelf? No, I didn't think so. That is your proof that gravity cannot be used as an energy source - because, as Omnibus also said, gravity are not energy.

The pencil on my desk is moving at speeds we will never understand.
The earth spins, the galaxy expands, the pencil is moving.

Stay on what topic? That there is no prrof that apples are a railroad? The case is closed, don't you understand?
