Doug White fired this volley in

I think the Micro-Drop is supposed to sort of spit at
things in small enough droplets to avoid a big mess, but big enough that
they don't end up drifting all over the shop & into your lungs.


So-called "CDA" or "controlled droplet applicators" are common in the
agricultural market for applying herbicides, etc., where wind drift would
be a problem. I see no practical reason why a CDA system would not work
for minimal-flow coolant application.
