Hello,
I am curently working on a project which needs a small spray of alcohol sprayed on a component once a minute. The problem is that it needs to be compact and can be powered either by a rotating shaft or an unstable 5v dc current. Any suggestions?

Ha Ha Ha, Its known as a seeback generator

Seebeck, why the alcohol?

Coolant

I know the basics of a Seebeck, guess you are trying to keep one side cool while the other is hotter. What is your fuel source for the heat. Would a small recirculation pump of water due the job?
