    Some of my Japanese electronic pianos now use a 1 Farad, 5V memory
    capacitor, instead of a memory battery that goes dead in a few years and
    requires me to replace them. Every time you plug the piano into the
    wall, it recharges this monster cap, which about the size of a button
    battery these days, almost instantly, ready for another month of no
    power and not lose anything.

    I've been dreaming of finding how to mount a couple of these in parallel
    into the Nokia tablet as a "backup battery" for just that 10 seconds it
    takes to pop out the dead battery and pop in a charged one....WHILE THE
    TABLET WAS BOOTED...not losing anything.

    This technology may be just around the corner replacing the whole
    chemical battery scheme all together with a powerful, ceramic,
    SUPERcapacitor.

    Zenn electric cars of Canada has a deal to use these massively powerful
    capacitors, that are quite tiny and light in comparison with current
    battery technology, TO DRIVE THEIR ELECTRIC CARS hundreds of miles at 70
    MPH!

    Google EEStor and have a look around. If this technology happens, they
    may have just eliminated the biggest stumbling block, batteries, to
    electric anything! Capacitors can charge as fast as you can provide
    power to them, unlike chemical batteries which take time to charge and
    are inefficient. Of course, you'll need 3-phase 908V at 200A service to
    recharge your nice electric car in 30 seconds....or less. Kilowatt
    Hours stored in EEStor still have to come from somewhere. The faster
    you recharge, the more instant power you'll have to provide to recharge
    it.

    Imagine your portable electronic devices you plug into a charger that
    uses as much power, in a few seconds, as your electric stove.
    Capacitors charge without getting warm....a sign of great storage
    efficiency. The only loss is a series resistance, easily overcome by
    slowing down the charging to a few minutes instead of a few microseconds
    at 5000A.'

    The car, by the way, will run 250 miles at 80 MPH and the massive
    charger will be limited only by your source power line amps, around 2
    hours to fully recharge, dimming the lights in the neighborhood in the
    process...(c; The lights in the den might blink recharging your
    sellphone from the 240VAC 50A load for 8 seconds....
