Fine for motion, but like solar panels, trying to generate electricity efficiently becomes an issue. Usually the chemicals required to do so are enough to outweigh any environmental savings, and these turbines spin faster and are much bigger than mills. Then there is all that's required to get such a volatile supply of electricity onto the national grid. -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
