JTM³ Posted May 22, 2006 Share Posted May 22, 2006 Are there any other ways of extracting zero point energy? The only one I've heard of is that cassimir effect thing, which is pretty much useless because the plates can't be unstuck. So will this ever be a viable energy source? Does science hint at a "subspace" star trek like dimension? If there was another dimension or if we could intereact with a universe made of energy (according to string theory's multiple universe/dimensions), if we use as much energy as we extract, would that bypass the laws of conservation, which says you can't "create" new energy? I'm no expert of course, so please correct me if there's anything wrong in that description. Link to comment Share on other sites More sharing options...
Phi for All Posted May 22, 2006 Share Posted May 22, 2006 Are you suggesting a connection between the concepts of ZPE and multiple dimensions? AFAIK, ZPE is just a hypothesis that the seemingly empty space between matter has an extremely small amount of heat in it, barely above absolute zero, but since their is such an incredibly vast amount of this space the energy involved is equally incredibly vast. I don't know that ZPE has been linked to M or Srting theory though. Link to comment Share on other sites More sharing options...

Norman Albers Posted May 22, 2006 Share Posted May 22, 2006 I challenge the quantum hypothesis of the vacuum. Just because there are many quantized photons does not mean that the native characteristic of the vacuum is that of a "ficticious oscillator". Quantum theory as we have applied it produces a ridiculous result that is not small. Ten with one hundred and twenty zeroes??? Link to comment Share on other sites More sharing options...

[/quote'] Quantum theory actually predicts an infinite amount of energy (half a photon per mode, for an infinite number of modes), but what's relevant is the energy difference between two states. So we normally ignore the infinity, as it's not accessible to us as an energy source. However, the Casimir effect, and the inhibited or enhanced decay rates seen in cavity QED, do agree with the "particle in a box" picture of QM.

SmallIsPower Posted May 25, 2006 Share Posted May 25, 2006 If there's such a huge amount of energy, there's got to be a way of harnessing a useful amount of it. Anyone who insists otherwise, without proof, is like someone who in 1905, saw E=mc2 and claimed the only energy that was available from matter was chemical.

The first statement you made is a broad, qualitative statement that predicts little and doesn't make sense in the face of modern scientific knowledge. Einstein's paper in 1905, on the other hand, was a specific derivation that quantitatively predicts the value of energy produced and was entirely based on well known scientific principles of the time. There's no reason the second should follow from the first. Link to comment Share on other sites More sharing options...

Klaynos Posted May 25, 2006 Share Posted May 25, 2006 Black holes, exploding? That's a new one on me, but then again I'm not much of an astrophycisist.... What I have heard of though is hawking radiation, which results in blackholes giving off radiation....

A more apt analogy is using mgh for potential energy, and then using a huge number for h. The table is at 999999 meters, and the floor at 999998 meters. That's a lot of energy, but only 9.8 J/kg are available to you. h isn't the important value. [math]\Delta h[/math] is. Link to comment Share on other sites More sharing options...
Norman Albers Posted May 26, 2006 Share Posted May 26, 2006 I say it is a mistake to connect the fact that there exist many quantized photons, with the characterization of space as only a quantum oscillator. This is ad hoc. We atoms are as vending machines working on nickels, dimes, and quarters. What can we know of any possible sea of pennies? Link to comment Share on other sites More sharing options...

It's there for a one-dimensional potential; it's [math]\hbar \omega (n + \frac {1}{2})[/math] for each mode. It's that pesky "1/2" that's the source of all the issues. But that 1/2 has to be there. The Casimir force and the decay games occur when you eliminate modes from the system by messing with the boundary conditions, but energy conservation is not violated. The issue of other dimensions becomes how to interact with them. We don't perceive them, and they are presumably orthogonal to the ones we do perceive.

abskebabs Posted May 28, 2006 Share Posted May 28, 2006 Sorry if I'm being ignorant, but what exactly does the Schumann resonance have to do with negative energy? This thread is getting quite confusing, Swansont seems to be the only one I can understand just about. It seems this stuff is far beyond my scope at the moment, and only with patient, persistent study and thought will I ever be able to understand it.
