Just for 'M' I have included a ' No, I would not buy it' option on the poll on my forum, it makes sense I suppose..

The wind chargers output at present is approx 0.5 Watt @ 12 mph, not great compared to a solar panel.
Please remember, this is a prototype.
'Betz law' suggests a power rating of 1 watt for a 12" (30cm) diameter propeller at 80% efficiency in a 10 mph wind, so some improvements are needed, we have about 50 planned.
So this is the figure we will be aiming for in the production model.
Also remember, the wind can blow 24/7 unlike the sun's relative short 'window of opportunity'.
