      No friction basically means that the force being observed is quite small...

      You have to understand that article was first translated from scientific talk to reporting talk, and now it's being translated back to /. nerd talk... (which isn't scientific talk btw).

      An example is how they first found the value of the constant of gravity. They put two humoungous iron balls near eachother, and noted the very tiny torque they induced just by being near each other.

      The fact that the observed effects were tiny doesn't mean they don't exist.

      Maybe that's the cool thing about scientific curiosity - the things you discover don't have to have commercial value in order to be discovered.

      Consider this: when it was determined that a current flowing in a wire produces a magnetic field, or when Faraday discovered that moving a magnet near a wire or coil of wire can produce a voltage, I'm sure a lot of people said, "but seriously, what would this be used for?" And they probably said the same thing about countless other things that were discovered in situations where the effect was so small that they had no apparent use.

      Of course now we look back and say, "what a dumb question! How could they now know these things could be useful?" And maybe 200 years from now somebody will look at this archived announcement on Slashdot and say the same.

      Then again, maybe this will turn out to be a misinterpretation of the experimental observation. Time will tell...

        Even so, one needs to keep perspective. At risk of sounding religous: if that sort of thing makes one "lose one's faith" in "the system", then that faith can't have been very strong to begin with. Meaning, if you really understand the scientific method, then you'd realise that over time it WILL expose the fakes, and we can actually be quite relaxed and confident about that. The system itself is sound: the only thing we should worry about is society giving up this system in favour of another. To quote Carl Sagan: "At the heart of science is an essential balance between two seemingly contradictory attitudes--an openness to new ideas, no matter how bizarre or counterintuitive, and the most ruthlessly skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense." ... "At the same time, science requires the most vigorous and uncompromising skepticism, because the vast majority of ideas are simply wrong, and the only way to winnow the wheat from the chaff is by critical experiment and analysis.".

        This essay by Jearl Walker [haxial.com] is an interesting and insightful read that relates this notion of "faith" in physics (read right up to the end).

    It sounds like they're saying the angular velocity will increase if the rotation is frictionless. Why won't this phenomenon cancel out at equilibrium amount of friction and keep the object spinning at constant angular momentum forever? I should also accelerate an object with a small amount of friction but at a slower rate than a frictionless object.

    In any case, we're talking about building a perpetual motion machine here and throwing the first law of thermodymics out the window. This makes the cold fusion claims sound pretty tame. At least they said where they were getting their energy, here it seems to come from nowhere.

      Yup, thats what they said.

      They didn't say it wouldn't. Presumably that is what would happen.

      I[t] should also accelerate an object with a small amount of friction but at a slower rate than a frictionless object.

      Yup. In their experiment the wire supporting the sphere was applying a counter-torque, it was just small enough that the new force was able to overcome it. By calculating the amount of torque generated by the wire after the number of revolutions made by the ball, they would have the static force generated.

      In any case, we're talking about building a perpetual motion machine here and throwing the first law of thermodymics out the window.

      Not likely. The kenetic energy of the rotation is probably balanced by a reduction in the net charge on the object. What they've got is basicly a really, really weak electric motor. A charged object in free fall would probably increase its angular momentum until it didn't have any charge left (then gravitational effects would probably eventually bleed all that energy back off again).

      What I wonder is if its reversable, so rotation can be converted into a charge on the object.

      Or here [aip.org] if you don't like pdf's.

      The article shows much more clearly than the pop news release that the rotation has nothing to do with quantum spin, and is entirely a classical electrostatic phenomenon. I will try to translate the article briefly:

      Essentially, when you apply a charge to the first of the three metal spheres, the charges all repel each other and go to the outside of the first sphere. This exerts a repulsive force against the like charges on the other two spheres, causing an imbalance as more charges are pushed to the far side of the spheres (from the first one) than are on the close side of the spheres. Then, because the second and third spheres have an imbalanced charge distribution, they also exert forces on each other which further displace the charges.

      The displaced charges result in a potential which isn't perfectly balanced like two spheres would be, and the resulting calculation shows an interaction proportional to 1/(r^6), where r is the separation distance, which yields a rotation.

    The Applied Physics Letters paper is just two pages long. There is no new physics here. Here's the skinny.

    Sphere A is charged up; the two others, B and C, are at different distances from A. Each sphere is polarized in a non-uniform way (because each sphere has two hemispheres, one closer to the charged sphere and the other farther... just as tides form on Earth due to the moon).

    The potential at the surfaces of B and C might be uniform but the charge distributions are not: they are dipole. Due to this dipole interaction (the more negativey charge hemisphere of one sphere wants to be closer to the more positively charged surface of the other sphere), Spheres B and C then tourqe to a different angle and will either a) stay there in the presence of some friction or b) oscillate back and forth in the absence of friction. Of course, there is always some element of friction due to the air and wire, but one can compensate by also oscillating the potential of A to make positive feedback, I imagine.

    The press release was, in this physics grad student's opinion, horrible. Implications that this research has some impact on our understanding of electrostatics or (gasp) quantum mechanics is irresponsible. It's a cute trick, though, and I'll bet it will find applications in mico-,nano-tech and perhaps other research areas (e.g. experiments requiring precision angular measurements [washington.edu]).

    Sorry, if you aren't browsing from an institution that subscribes to Applied Physics Letters, you probably won't be able to download the article for free. But I'll be happy to paraphrase what I understood from the article:

    This phenomenon was purely predictable from Coulomb's law and Gauss's laws of electrostatic attraction/repulsion. Many of you should have learned about these in freshman physics. The spheres were arranged in an assymetric pattern, so rotation isn't breaking any kind of symmetry. If you arranged their spherical balls in a mirror image pattern, the rotation will reverse. The authors aren't trying to say they measured some kind of new mystical force that hasn't already been understood for 100's of years but simply that there could be an engineering application that no one had thought of before.

    They're "holding the potential constant" on the central sphere, despite any leakage from irregularities in its surface. The two uncharged spheres nearby should create a stronger field in their direction. Corona discharges toward the space between the spheres could result in a net outward motion of air there, and inward motion of air between the outer and central spheres. Friction of this air against the outer spehres would provide a rotational force, in opposite directions on the two spheres, with no net force on the central sphere.

  • This is funny- yesterday I was picking up a print out here in the Physics Department, and I happened to notice a stray copy of this article lying next to the printer. It is a super easy read for anyone versed in physics up to the intro-graduate level, and took up just 1 or 2 pages. The beautiful thing about this experiment is that it SCALES- in other words it works for very very small things (think nanomotors) and larger things (macroscopic systems, like the actual experimental setup). Just a beautiful p

    Sorry :-)

    In all seriousness, keep up the good work.

  • Plus the earths magnetic field. What about the interaction with that or perhaps gravity

    Rotating the sphere (from rest) requires energy. Therefore, the DC voltage applied must require some current - where is it going? and what magnetic field does it produce? and how do all these fields interact? If not you could cover the spheres with insulation to maintain their charge, put them on really good bearings, and have a perpetual motion machine. At the bottom of the story is a big plug for this cool university. I suspect they're just trying to get more $tudents using neato-sounding, but bogus scien

  • Dead or Alive [thesonglyrics.com] figured this out in the 80s.
  • If the spin were being shown to be a result of quantum spin. (We haven't been shown that quantum "spin" is not the mechanism by which this occurs, either.) If it were then it would imply that all these funky "Free energy" systems would actually be possible. Unfortunately, since they are putting energy into the system, it is interesting and will (I am sure) lead to advances in our understanding of the universe, but doesn't say any such thing. And here I was hoping to run my car on free energy :(
