It may be useful in looking at the drawbacks of some of the tricks being touted thus far.
It would seem that Flux has correctly ruled out low wind usage if you require gearbox/hydraulicpump/or other torqueconverter systems.
It seems to be the case that low wind speeds would be the norm in your area (10mph av). It may be time to bite the bullet and do the unthinkable, and just charge batteries... a proven use of low to medium windspeeds, and use the batts as tempory storage for your low wind capture energy.... every watt here is a bonus, you would not have captured it for your use before, and yet now it may provide the bulk of your disposable energy income.
Yes you can see whats coming next, just run a 3hp dc motor to direct drive the induction generator. Here you will lose maybe 15% (a decent dc motor is capable of 85% i believe.. ie 2600w in for 2200 w output.
This will give you an energy storage for the low winds, and the gennie will direct drive (with batteries as filter) when decent winds arrive.
The only thing to worry about then is the turn on/turn off of the dc/induction generator set. Looks pretty simple to me. a very basic voltage detect on the battery pack would start induction motor from the grid, and then turn on the dc drive to over run the ac motor.when the voltage drops below cut off point, all stops,and batteries resume their charging on winds too small to usefully convert in real time.
This intermittant use of the gen set will extend the brush life to a large extent, and my experience of this kind of dc motor is that used 2 hours/day,it will last decades. (my experience on over a hundered floor scrubbing machines.. Ohio 36vdc 2hp pm motors some ran 25 years with no brush maintenance 2hrs/day)
So by introducing an inefficiency of a motor, instead of a torqueconverter or hydraulic, or gearbox even, we get to use the lower wind speeds, get maximum wind capture, and solve the highwind problems that Flux eluded to....batteries act os load plus the dc genset.
This then uses current technology, is solid as a brick s---house, and has no obvious weaknesses.....that I can see.
Yes we are introducing inefficiencies, but we are also getting power from incidental winds and winds which we would have otherwise ignored.
ok time to kick me around I guess
