Using an industrial DC generator and rugged
handle, visitors generate power to control various "stations"
within an exhibit space. Stations can either be clustered
for maximum compactness, or distributed throughout a huge space for
the dramatic impact of 'action at a distance'.
Visitors can easily feel the changing drag on the
handle based upon their choice of station/load.
Optional:
- Each motor may be equipped with a voltmeter and ammeter to allow
user to see the direction and flow of current generated by their
cranking activities and choice of station (and thus electrical
load).
- Certain designs allow the visitor/user to connect their generator
to their choice of station through an ultra rugged "patch
panel".
- Since the DC generators are in fact simply DC motors, two generators
may be connected together allowing two visitors to crank together
or against each other, where by working together they can generate
more power, or working against each other, generate none usable.
And, if connected in parallel, whichever generator handle is turned
will cause the other generator/motor handle to turn by itself.
Feels very cool for both users. (Care must be taken in design
however to avoid the cranking by one visitor surprising another
with a suddenly-moving crank handle applied to the chin...)
