We've been discussing the possibility of installing a turbine here for years. Sometimes the wind is so strong that you have to turn your back to it and just wait, but most of the time there isn't much wind.
Our trees are fairly symmetrical with only a very slight tendency to grow leaning downwind, so according to your tip, we are not likely to get significant power from wind at this location, right?
If the turbine was cheap and an educational / fun project to install anyway, would it be more practical to use it to pump water up 100 feet into a large existing storage pond, rather than try to charge our existing solar batteries?
