ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************
We have just such an exhibit, and our motor has run well for 6-7 years.
It was built by a volunteer, who got the motor from
Jade Mountain Inc, Boulder Colorado 303-449-6601. They seem to have
become part of Realgoods.com, but the guy there thought they could still
get them (GN108 5A permanent magnet DC generator, was $200)
A radio is fun to add (we just hot-wired to 9V battery terminals).
We've got a couple of different bulbs too- incandescent (12v from
McMaster) and fluorescent (Coleman makes them now for camping); the
fluorescent takes a lot less cranking, so makes a nice example of energy
costs.
