You Spin Me Right Round?

i was thinking more about how to incorporate human power into our every day commutin transportation. I think that human power is a much neglected thing terms of public transportation. It's completely clean, except for the farts. And then everyone only needs to have food, or maybe like a super concentrated carbohydrate drip while they are working to peddle themselves forward. The benefit is also, it can work across water as well. If you make the materials out of floatable materials, and get it to flap with the combined power, you could probably either, through sheer mechanical energy, put it into wings that are flapping, or you can have battery storage so that you can power electronic motors so
