There’s a Starbucks in Washington that has a bicycle powered blender and the customers make their own drinks or something (I couldn’t find any information on why they’re doing this or which one in WA, but there was a video on Keith Obermann last night). So, here are some resources around the web on bike blenders, seems pretty easy to make a DIY version.
