It might be less efficient than a belt-driven 'charger by direct comparison, but I think the system could have big advantages when considered in relation to an average driving cycle. For one thing it's not going to be required all the time, it will only be drawing power when the engine is building boost, whereas a normal 'charger saps power from the drivetrain all the time. Particularly valuable at cruising speeds. Also, as mentioned in a few articles, if combined with a normal turbo it could actually charge itself and do away with the wg at the same time, brilliant!
