Wind is a movement of air. No air = No wind.

Well, then you have anwsered my question, I just find it interesting that so many people believe it is possible, and even some people who are famous scientists, like Tesla.
And Geny uou have missed my point, if we have a fan and start spinning it, it will spin but will eventually stop because of friction and gravity.
No friction and no gravity=endless spin.

I got your point, but I just can't think of anything that will make it possible. Wherever there a machine that creates energy there's friction because friction exists wherever particles exist.

And Me + World Domination device = World Domination.
There's nothing wrong with the equation itself its just that one part is missing...
You say "no friction" like it's not a big deal. No friction is a very big deal and can't just be dismissed like that. And even famous and knowledgable people can be wrong sometimes Carcity.

oh right, forgot that the enegy converter converts the friction, my bad.

The Energy convertion isn't the point. Apparently there is suppose to be friction at some point in that contraption but the point is that there will be friction everywhere else too. Whether they want it or not. Thus Energy will be lost.

And even if it didn't, friction energy does not come from nothing, it is converted from the energy coming from the battery. So if you take that friction energy and convert it back, at best you'll get exactly the same energy as the battery generated in the first place and that's in absolutely ideal environment.

Another question then; How is lightning created?
A lightning blast holds a massive amount of energy, and when there is lightning there often are many of them. that means it must be a giganormous amount of energy in those in total, where does this energy come from?

I have actually known in detail how it happens, but I forgot.
Basically, lightning is a lot of electrons moving from the ionized particles sky to earth (to the lowest potential possible). As to why these particles get ionized in the first place... I have no idea.
Edit:
From wiki:
Quote:
How lightning initially forms is still a matter of debate: Scientists have studied root causes ranging from atmospheric perturbations (wind, humidity, friction, and atmospheric pressure) to the impact of solar wind and accumulation of charged solar particles. Ice inside a cloud is thought to be a key element in lightning development, and may cause a forcible separation of positive and negative charges within the cloud, thus assisting in the formation of lightning.

didn't azagal prove that free energy is possible and normal?
Quote:
The law of conservation of energy is an empirical law of physics. It states that the total amount of energy in an isolated system remains constant over time (is said to be conserved over time). A consequence of this law is that energy can neither be created nor destroyed, it can only be transformed from one state to another. The only thing that can happen to energy in a closed system is that it can change form, for instance chemical energy can become kinetic energy.

I think he means that if it can't be destroyed, then it can be used again, but energy is lost in the process, or well, not lost but transformed inot another form.

Yeah, energy is not destroyed, but it either dissipates in a matter that we can't collect efficiently or is used by us (like light and heat). So we can't really "recycle" energy like this.

Well, theoreticly it is possible to gather all the electricity again and reuse it, but this wouldn't lead to anything as this could only power itself, and nothing more.

No. And Fauch not you too Oo. Enery can not be destroyed yeah. How does that mean that we can create it out of nowhere? The "destroyed" means that it can not be lost. As Geny said it will transform into any other form of Energy, but it will not disappear simply change.

I have a slightly different question. The current theories say that the Universe will endlessly expand and spread out the matter into separate atoms of near 0 Kelvin temperature. This I don't want to believe in since it goes againts all the harmonic cicles of life and death periods where what has become dead will be reborn from it's remains (possibly in a different shape).
Now, 0 Kelvins means that there is no energy around - where is it? Will it convert to mass again as matter and dark matter? And if it will, maybe that mass will be sufficient to make a pull on the spacetime fabric and revert it into a single point plating seeds for a new Big Bang.

@Azagal, that theory was different than my other ones.
@Veco, well, I myself don't believe that the universe is expanding, but what if the energy there is unexistent, energy doesn't have to be everywhere, right? Right?
And if we're gonna start talking about space then I got a whole lot of questions to ask...

Which don't seem to be real questions because you seem to ignore the answers. And ehm it's very cute that you don't believe that the universe is exspanding, that will however not change the fact that it does. Yeah the theory was different but still: NO!

Hey Az, scientists think it expands because everything in it is drifting away from each other, this however doesn't prove that it expands, it only proves things are moving. and besides, we have only seen a small piece of the universe, and in all bigger maps of the universe, earth has been in the centre, what is it that says we're not the ones that move.
and I'm not ignoring the anwsers, I'm questioning them with new questions and arguments, it's the way of a discussion see?

A windmill is driven by wind (as said), motion energy in the air particles. This energy (about 20% I think) is caught by the windmill and moves the motion energy to the inside of the mill, where "magnetic friction" is used to create electricity. This means that you could indeed (in theory) maybe create a windmill that keeps spinning in space if you remove friction and gravity. This would also mean that you get no electricity of it.
So having a perpetual machine, a windmill that keeps spinning, MIGHT be possible, but it is EXTREMELY unlikely that we ever reach 100% efficiency (i.e. 100% of the energy (the spinning) is reused to keep spinning). However, it is possible to create near 100% efficiency i.e. having a windmill that reuses 99% of the energy to keep spinning. This would mean that it could keep spinning for a long time, but not forever.
Creating energy from it would mean that it would reuse more than 100% of the energy. Which in itself is obviously impossible.
Let's make a comparison. Let's say you have a glass of water. You pour the water into a new glass. Then into a third glass. It is POSSIBLE, in theory, that all of the water that was in the first glass will end up in the third one. How ever, at least a small ammount should be left in the other glasses (if only small drops) or end up in the air. However, it is impossible that it ends up being more water in the third glass, unless you add new water somewhere along the way.
