Here in Holland we have a lot of windmills and yes they do cause horizon-polution, but you get used to it after a while. The noise they create is very little, I sail within 50m of'em but never hear a squeak (They're in the lake so we use them as gates ).
I dont know about birds getting killed (airkill) but I do know of this german guy on a yacht that tried to stop his wind generator in a storm and got his skull smashed. The power produced is debatable, a lot of farmers have them for financial reasons, since they are heavily subsidised. The latest plan is to built a huge windmill park 10km offshore.
Rolf's idea for a bicycle generator is excellent, although you could probably find an old hand windgenerator at a 2nd hand chandler.
