Hey Paul,
Maybe this next remark is the result of being up too late, but have
you seen the water misters they use in Vegas to keep stuff cool
outdoors? What do you think about using those for fuel?
Chris
I have not seen one. Got any pictures? Sounds interesting.

Chris, ET AL
I have not seen the Las Vegas misters, however, most misters use a
small hole in the nozzle and a high pressure differential to create
the mist. Pressure varies between 40 and 150 psi or higher.
Similar to fuel injectors using 40 - 60 psi to create the fuel spray
pattern.
