Putter bushings?! Are you a caveman? Everyone uses magnetic air-gapped bearings now.^ya but what kind of drivability would something like that have? Sure zero emissions is cool and all but zero hp would mean it's immobile. I'd talk with your friend and find out if he meant 0 hp while moving as in a new planetary sun dial operated electrostatic tire and wheel design that uses the cast shadow from the protruding sun dial rim spoke to create inverse daylight sensor triggers to power the helix coupling flanges on the putter bushings of the centralized intelligence agent of the tie rods.
That would work fine to stimulate electrokinesis which could drive the new lightwheel negative calory wheels infused with peanut oil, but it would require a hydromatic fluid coupling dewhicky with Kevlar plated-brass nostrils and advance polymer photosynthetic Metallica syntax.
I think your buddy has bad info, take him to a grave yard, string him from a tree and threaten him until he spills the beans.
