Hi MMDers,  Just a little food for thought:

The player piano is just about the most environmentally friendly machine
in operation today (excluding the lead tubing hazard controversy).

The player instrument produces no harmful emissions; no carbon monoxide
exhaust.  It runs on air and electricity (or foot power).  Electricity
is a renewable energy and air is (more or less) plentiful and safe.
You could literally run your player off the sun.

The player instrument does not rely on the diminishing supply of fossil
fuels or depleting energy sources.  As the world turns to renewable
energy sources, the player shines through as a clean machine from its
beginnings.  Is there a better way to make music?
