utopian vision Toyota had in mind when it formed the Wireless Battery-charging Alliance with WiTricity. The young Massachusetts-based company is pushing "resonance" technology, which charges electronics without contact and is supposedly more efficient than induction-based charging -- a category that includes the popular Qi standard. This new partnership ups the ante, adding electric vehicles to the list of chargeable devices, a vision of the future where Prius batteries can be filled wirelessly, while sitting in driveways and parking garages. Exxon's engineers are no doubt working to perfect the hose-free gasoline transfer as we speak. PR after the break.
