DIY Wind Turbine Generator?

[Cole Milne]

This weekend I am looking for a project to do. I brainstormed and came up with a DIY Wind Turbine to charge a phone. I found this http://www.reuk.co.uk/Make-a-Mini-Wind-Turbine-Battery-Charger.htm and I was wondering if you guys know of any guides or have any advice/ suggestions. Thanks!
