Mouse Uses RFID Instead of Batteries

ValourX writes "NewsForge (part of OSTG, like Slashdot) has a review of a mouse that is powered by RFID (and yes, it works with Linux). It's cordless and uses no batteries -- you just have to keep the mouse within 2 inches of the mousepad for it to work. What else could be powered by RFID?"

    One, it's not RFID. RFID is a means of identifying things, that happens to use the RF from the detector as a power source. You can use RF as a power source without it being RFID.

    Two, bateryless cordless mice are old news. I've got a Graphire 2 next to me that's done that thing for three or four years.

    (a) This has nothing to do with RFID, as the parent stated.

    (b) Mice powered by induction from a special mousepad (or top-of-the-mousepad) have been around for a very long time. Presumably these didn't catch on for the same reason that optical mice that required a mousepad with a grid didn't catch on -- people don't like being forced to have a particular mousepad.

    (c) Tesla owns your ass, mouse-people -- he powered lamps with remotely transmitted power twenty-five miles away.

    Any program relying on (nontrivial) preemptive multithreading will be buggy.
