Has anyone looked at the atomizing hudimidifiers that produce "cold
steam"? They have what looks like a piezoelectric device (maybe emitting
ultrasonic sound ?!?!) to instantly vaporize water. We had one of these
things years back and I wondered if the technology could be applied to
fuel atomization in carburation or injection. It seems that if the device
could be controlled by the ECM (if necessary) a known vapor curve could be
delivered. Don't know what this would do to a MAF tho...
