:When showing my 1927 Buick roadster at car shows I usually have my antique portable phonograph sitting on the running board and playing. Yesterday an old boy said he once saw a radio that was powered by the air from the tire of a car. Would play till the air pressure was at a certain point and then quit so they could still drive on it. has anyone heard of one of these and could point me toward any reference material on them? Thanks, Randy
hi randy i have an old set that runs off of a motor generater if you could run the motor with air pressure it might work but then where would you get your filament voltage? i've never heard of anything like this but that doesn't prelude its existence.butch
