USB 3.0 promoter group haven't taken the threat of Thunderbolt lying down. They've been working long into the night (we imagine) screaming "More Power!" and "Liiiiive, damn you, liiiive!". In a press release, the group announces a new power delivery specification which will push USB 3.0's limit from 4.5 watts all the way up to 100. You all of course remember that Thunderbolt's maximum is a mere-by-comparison 10 watts. Brad Saunders, the promotion group's chairman, believes that the new standard could enable USB 3.0 to supply a laptop with energy at the same time as it delivers data between your devices. (After all that time sponging off your laptop's meager battery it's about time your USB-powered foot warmer started returning the favor.) At the moment it's only a specification and won't be implemented until 2012 at the earliest, but this could just turn into an arms race of electrifying proportions.
