    How are they storing and harnessing the recovered energy?

    Pneumatic pressure? Hydraulic pressure?

    It wouldn't be electric, b/c that would require massive batteries and motors.

    For whatever reason, I thought they would have had some similarities to the KERS system in the F1 cars.... Because they are out of F1, are they trying to avoid the naming link?
