British Scientists Reverse Casimir Effect

An anonymous reader writes "The Telegraph reports that Scientists at the University of St. Andrews have developed a technique to cause the Casimir effect to repel instead of attract. This discovery could lead to near frictionless machines or in theory even levitation."

      So you're already repelled. When they reverse the effect, maybe you'll be attracted. It will be sweaters every day for you.

    FTA: "The force is due to neither electrical charge or gravity, for example, but the fluctuations in all-pervasive energy fields in the intervening empty space between the objects and is one reason atoms stick together, also explaining a "dry glue" effect that enables a gecko to walk across a ceiling." ... and now that scientists have figured out how to reverse the Casimir effect, this will soon enable geckos to walk on the floor.

    That would repel from the floor, but not from another cat with another slice of buttered toast strapped to its back (which is what this can potentially do).

    From what I remember of the buttered toast cat, doesn't it end up spinning just above the floor as the cat tries to land feet-first and the toast tries to land butter-side down? If so then why is no-one wrapping these cats in wire, putting them between magnets and throwing them off surfaces en-mass to generate electricity while they spin?

    It's all well and good until you have to take the cat down for maintenance. Have you ever seen a cat that's been wrapped in wire, strapped to a piece of buttered toast, and spun for 3 days? Let's just say it's not happy.

    Actually, the cat will freeze in midair suspended on its side, because in that case, the direction of spin that requires the least work to get the cat/toast to the correct position are in opposite directions with an equal magnitude. So, sadly, it will hit static equilibrium, so you'll just have a crazy floating cat, not a crazy floating power-generating cat.
