Sorrry but no free ac this time, it would use more energy to create more compressed air for the air conditioning then it would use to power the car; that is if they used a hybrid air electric system that took full advantages of high powered triangular lasers strobing on a polished silver cone spinning at 300+rpm by compressed air. Then they would have enough propulsion power to travel the car and compress your air conditioner. That is assuming minimal energy was lost in the system, correctly compensating for breaking and conserving that energy to accelerate later.
