While Bluetooth headsets are a dime a dozen, ones powered by the sun like Nuclear Man from Superman IV aren't. Orange claims that its Iqua Sun is "the worlds first" [sic, italics theirs] solar-powered Bluetooth headset. Fancy! The green half-ouncer gets 200 hours of life on standby and nine hours of talk time in darkness, like in an elevator on the moon. It'll run you £49.99, which is about 105 American clams.
