Thanks for the replies. Yes, I'm aware that even a fit amateur cyclist doesn't produce much power in the grand scheme of things :-) Hence why I'm not investing much money or resources into this project!
Also, thanks for the windmill tip-off. I'll take a look at how those guys do it.

Do you know roughly what kind of power you got out of that setup?
