Depends upon the working voltage. I had seen 1 farad caps 20 years ago
that were not much larger than a couple of small mercury cells. I'm
sure they've gotten them even smaller by now.


True. I forgot about the voltage aspect, as I was thinking about the
sizes used by the auto sound nuts in their vehicles. A one Farad size in
those applications is about the size of a one litre (about a US Quart)
container. I can't imagine a hand shaken flashlight would make enough of
a voltage to allow a size reduction of any great magnitude..

I'm probably wrong, so please post any more information you may have
access to.

As for those car stereo lunatics, I think they will all be deaf after a
few years.

I agree. Unfortunately those who run their home entertainment, car
stereo and Ipod systems at very high levels will find themselves
cranking the volume gradually higher as hearing sensitivity declines.
Those individuals should be encouraged to simulate damaged hearing and
listening through hearing aids before the permanent damage occurs. A
few of them might just turn the volume down.



I can hear their bloody bass five cars away. How can the use
of headphones by a car driver be illegal when that megawatt idiocy is
allowed to continue?

Yes, I agree. But the desire to draw attention to ones self by making
the loudest possible noise isn't limited to car stereo systems.
Consider the exhaust noise from some brands of motor cycles and several
cars.
