Henry,
I guess I am a complete moron, but i dont have whatever it takes to run a
fan. I do have many PC fans in my office, but what can i purcahse to run
them? How long will a battery last?

If you weren't one to play with DC motors, batteries, and DC power
supplies
(the ugly little black transformers you plug into the wall (wall warts))
as a kid, kludging together a wall wart and muffin fan for ventilation
is probably a bad idea for you. You aren't a moron, you just didn't
entertain yourself making dangerous toys as a kid.

If on the other hand you're willing to try the second child hood
approach to learning about electricity and motors, start with
one of the cheap education kits from some place like radio shack.

Apply those concepts to your muffin fans and a wall wart (Much better
to have a scavenged wall wart than to buy one from some place like Walmart
or Radio Shack). You'll be whacking fingers with a fan blade in no time.

Further discussion is probably beyond the scope of this newsgroup.

Will a PC fan motor suffice?
