Does the ability to heat eight ounces of water in three seconds interest you? Then take a look at this Teal quick Cup, which produces hot (we're not sure if it's near boiling) water by spinning the cold water you pour in around the spiral heating element. Not only is it fast, it's supposedly more efficient than a standard kettle or hot water heater because it only needs to be "on" for those three-ish seconds. Useful for your instant cups of tea or filling up a bathtub the dumb way. [Quickcup via Giz Mag via Boing Boing Gadgets]
