If I wanted to get a dinky little wind turbine to generate maybe enough power for a phone that could live on my apartment balcony, what would be a good way to do that?

I go into this fully recognizing that the economy of scale matters and I'm not going to get much electricity out of anything that doesn't cost $2000 and needs a huge open field to work, but I'm interested in the experiment and experience of getting a small wind generator. Are there any recommendations for kits or products I could experiment with?
