Nice Idea - No market.
FS 2001 impresses me as the best, most simple, independent,
(completely solar powered) efficient (best mechanical amplification of
stator output - motor housing and bell form an exponential path from stator to atmosphere.)
Don't see how you can beat it, unless you create a horn tuned to the
siren peak pitch. (I wouldn't be surprised if FS has already done that!)
How many sirens ever fail due to weather events interrupting power?
I know of only one case in a small town.
I am impressed how the 2001 can be placed anywhere without complication and cost of bringing power to it. Bringing power to an idealocation can be very costly and difficult.
Sorry for discouraging news. Do it as a fun project for a sirenear you!
Just wanted to clarify "completely solar powered"; its actually solar recharged, battery powered (if no AC feed at all). I'm sure you understand that Robert, but didnt want a newbie to get confused.
Again, neat idea, just not practical. Most newer sirens are DC motorized now, so that inverters aren't required.
