I was just wondering, when in physics, they spend a lot of time impressing upon you separating "weight" from "mass".

Most assuredly it's the case.

I was wondering however, if you use 1,000 liters of water on Earth and drop it 10 meters how much electricity you make versus doing the same on the Moon, the mass is the same, but less electricity is made, right? Due to the strength of gravitational pull having a lower acceleration of the water molecules, right?

Also, I've always been bothered by this question; "water dropping making electricity, is that changing gravity's pull to electricity?"

Well yes, it depends on amount of force you can generate, water floating in space will not give you kinetic energy as the mass does not try go anywhere.

Newtons law: Mass * acceleration = Force

No, it's changing (the potential energy that the water has at that height) into electricity. Somehow the water got up there by someone or something doing work on it (lifting it). You are just getting that energy back.

"Gravity's pull" is a constant force. You can't get energy out of it for ever, sooner or later you will reach the bottom of the hill (or well, or mine shaft).

What tonyw said + The water has been "charged" by potential energy orginally from the sun -> heat -> vapour -> wind -> rain. Then it was trapped on a mountain ready for us to use by letting it release its energy ase kinetic energy (movement) -> electric energy.

What will actually happen is that the water will be slightly cooler in the river below the powerplant than it would have been before the powerplant was built. Before the water would just have raged down the mountain creating friction and noise which eventually becomes heat. But by extracting the rage in form of electricity the water will not heat up as much as before. Not sure if it's meassurable, but it's calculatable at least.

OK, as the free forums in other sites are under other zone/name.

you should probably patent your designs for a frictionless, turbulence free turbine as soon as possible

Hi Broadblues,

I like your avatar. Did you make it with Blender ?

I know, out of topic again...

Happy new year here and on the moon.
Have a drink of water of course!

Since a lot of months without an amiga to love, I was lost.

Now I feel happiness again with a Sam Flex 800 .

@yescop

yes, it's a character from an animated movie, i started to make, but i got distracted by porting blender so never finished it!

Or even reuse some of the immense amounts of energy that NASA used to get some of that moon junk up there. All wasted.

I'm sure someone already has..

Powerplants are upgraded once in a while with newer and more efficient turbines.

Rockets definetly aren't verry efficient, you have to put all that energey in to raise the potetial energy of the space ship, then you have to put more in to stop the potential energy of the ship lowering to quickly!
