  1. More Slashdot hype by trenton · · Score: 4, Informative · on Fin-Fet Transistors on the Horizon
    And the hype lives on! Compare and contrast:
    • From the post: "... and 50 percent less power usage."
    • From the web site: "... new type of transistor which reduces power consumption by 20 - 25%."
    Somewhere along the way, that thing got twice as efficient! Amazing design.
  2. Re:Negative Refractive Index stuff and Solar Sails by markmoss · · Score: 2 · on How Solar Sails Work

    I found a reference to that here. The negative refractive lens can (in theory) be created with a 40 nanometre thick silver film. But to work, it must be at a "distance of 20 nanometres from the light source, since the system uses its near field."

    Sorry, here's #3.

  5. Some links by markmoss · · Score: 2 · on Negative Index of Refraction Created

    I couldn't find anything directly about the microwave refractor, but a search for "negative index of refraction" turned up three short pieces on the basic physics: 1 2 3.

    Note that these involve putting conductors into the near field of the emitter -- that means within a fraction of a wavelength of the light source or microwave antenna. But to me, that just makes the metal an added piece of the antenna, and one well known directional radio antenna uses an array of metal rods in the path of the emitted waves...

    I don't know if the rings and fiberglass arrangement is just a variation of this.
