Well, you CAN plug them into the AC line, but you'd better have VERY fast 
reflexes because it's going to smoke and burst into flames in your hand. At 
about 30VDC they tent to burst into sparks and flames, at 120VAC you're 
gonna get FIRE :).

I've done a LOT of tinkering with computer fans (had a model hovercraft idea 
about a year ago). For your applicaiton the best thing you could do is get 
some of the BIG computer fans (like mainframes), or a muffin fan from 
something other than a computer (lots of things use them). Shoot for 
something in the 115VAC range. They're out there, and they work a LOT better 
than the winpy 12VDC ones and don't require a seperate power supply. If you 
need one let me know, I have 220VAC fans in the 5" size in stock.
