ok, someone posted as I got an email, but now I can't find the post, but this pump may well work....

note it draws 5 amps, and it shuts off at 80 PSI (not sure how far the pressure has to drop before it turns on, likely < 60 PSI). 60 PSI will make reasonable mist, even if 80 PSI is better for fine mist.
A few years ago, I spent months researching a DC powered misting system for an outdoor summer star party I go to annually, thinking it would be very cool to run a patio mister hose along the upwind side of a shade awning and run it for 4-6 hours each afternoon, but back then I failed to find a 80PSI pump like this.
The typical mister nozzle is rated for minimum 50 PSI, with 0.5G/hour at 100 PSI, so running 4 nozzles for 6 hours/day, we'd need like 50G of clean water for 4 days, and if the pump is running with a 50% duty cycle, 120 amp*hours (or a solar charged 100AH system would probably suffice).
