Bose Electromagnetic Suspension - "Adaptive Drive" on steroids

I wonder if that power usage they mention is really true, or perhaps a bit optimistic.

Yeah, if you read the article it states:
[QUOTE=Siliconeer]In place of traditional shock absorbers, the prototype had linear electromagnetic motors installed at each wheel. Based on technology Bose pioneered at MIT, power amplifiers deliver electricity to the motors in response to signals from the control algorithms. The nimble motors are so quick and forceful, they can extend downward to roll the tire through a deep rut and then retract so fast that the all a motorist senses is a mild stirring. On the far side of the pothole, the motor operates as a generator, so the suspension requires less than a third the power of a typical car air- conditioning system.[QUOTE]
