well Ray,i found their web site

http://www.ampair.com/homepages/index.php?module=pagemaster&PAGE_user_op=view_page&PAGE_id=4&MMN_position=8:8

they seems to have a great deal of experiences
i will try to contact them,anyway just by looking i am learning for my 
project here
my blade is my probleme not the generator itself,,,
some years ago i built a transmission base on bycycle shifter ,,it worked 
many year
in  a chalet,,,,i have lost my planc now .and the chalet was sold and gone 
is my invention too


73/s
thanks all fo this duscussion,in those events of needs of telecom ,we also 
need auxilairy power too
