I would remake the classic Carters-style benchgrinder with a DC motor and battery system. I'd have the motor speed regulated at 2,880 RPM for the standard British pitch which all Americans recognize from old movies as a civil defence siren. Then I would undercut the market with a simple, inexpensive siren and control system that any city could afford and any local electrician could install.
Lex orandi, lex credendi, lex vivendi.
