AAA NICADS may be too small for this scale. I am talking a few amps per hour, more than any NICAD for that matter could/would supply without overheating.

A better solution than a car alternator would be to use a larger DC permanent magnet motor as a generator. If you want to use stuff from old cars, a radiator cooling fan motor may provide enough current as a generator. Years ago I made a windmill out of an old computer tape drive motor (Think large 1970s computer). I think the motor was designed to run from 24-48V so it put out 12V @ 10amps quite nicely at low RPMs.
Good point! WIMA has developed a capacitor not too big around with a capacity of 400F!
A 500F type is under development. One disadvantage they have: Charge is limited to 2.5V
The massive capacitor bank could be the garage filled with capacitors from bottom to top.
