Wow! Thanks. I looked it up, and more intense versions are used to cool sewing machines and other manufacturing equipment, w/o added power. People are also cooling with compressed air cans. Good to know.

Is interesting.

I want to think of things that I can make out of what I have on hand. Looks like you have to buy it.

Is interesting though.

The important thing, is to know the concept works enough for others to pursue it in larger practical applications.
There were related videos on air flow too-- speed of wind above vs. below a fan blade or airplane wing.
