General Cycling Discussion - Bike powered blender and others

So I've started a cycling club at my school, and we need to raise some money. Somebody suggested we use a bike-powered blender to make smoothies and sell them in the main quad on campus. I thought it was a fantastic idea, and we've got a design in the works. But it got me thinking, what else could we do to raise money that would involve bike-powered things? Our school is on a big "sustainability" kick, so we could use these things to get their attention, meaning it would be easier to squeeze a bit of money out of them.

Any ideas? My only other thought was a vibrating "massage chair" like their have at county fairs around here...

Ed Begley Jr. has a bike powered toaster. :D

I should mention that I'd prefer to do something which can be done without electricity if possible. Obviously this limits things, but I feel it would bring more of a gimmicky 'wow'-factor which could help in the fundraising effort...

I'd encourage you to think again about electricity-based gadgets. Think of your audience, the most electronics-savvy generation in history.

Well, there's enough to get you started. With the right interfaces, you can drive all sorts of mechanical items. With the right wiring, you can drive all kinds of electrical devices. Imagine several bikes linked to generators so you could play Rock Band with youyr buddies. ;)

Personally, I'd like a bike-powered TV. I watch TV when I'm riding my trainer anyway, it would be great to provide the power for the TV from my trainer.
