So Ethan came over yesterday and we made a VAWT. It pretty much is awesome and we polluted the stream. The only problem is it doesn't work because the bearings we have (wooden dowel through drilled holes) kind of suck. I need to acquire pillow block bearings somehow, that way I'll be able to have good bearings and balance it correctly (it is a tower and when the balance is off, all the pressure is applied directly to the bearings).
Also someone on a forum directed me towards stepper motors as a source for magnets. Apparently printers and vending machines have them... so if Richard has some old printers....

Fantastico!!
Do you have a picture of what you built?
Would some bicycle parts help the bearings? The pedal bearing or wheel bearing works pretty smoothly?
I do have some printers that you could disassemble if you wish. Email me off the BLOG and I can tell you where if that helps.
If this is part of Ethan's group work - encourage him to document it on his team's site.
