Please, someone explain to me why they would expect a windmill with less than a 5 foot diameter blade to be anything more than a trickle charger or battery maintainer? The basic formula v cubed for wind velocity and d squared for diameter wuld indicate that a 4 foot blade would never reach 100 watts until it's over 16 mph. It seems like, from the replies I've read, the wrenches, using small wind machines, are on the bleeding edge instead of the leading edge of small wind machines. It never gets windy here in the North Florida Swamp, however, we do a lot of work off shore.

Does anyone make a good wind unit with a blade over six feet diameter that is tried and true and costs less than $3000 that has a past record over 5 years in usewith no major problems. Also will it start at less than 10 mph, and noise will not upset chickens etc. gator tom
