Re: [RE-wrenches] Wind Turbine

Does anyone have experience with  APRS's WT10 turbine?  They've been 
around for along time, but I've not tried that turbine.

Ron and John and all,

SD Wind Energy out of Texas is representing what was the
Proven/Kingspan down wind turbines. They have a 3 and 6kW
turbine now but I heard through
the grapevine that they may have a 1kW in the near future.
Price is a bit high but they are solid machines.
https://sd-windenergy.com/

Other folks have been using the Braun turbine out of Germany
but that's really spendy.

The Whisper line was good, then Southwest Wind Power bought
it, they went under, a company from India bought it, then it
went to Japan
and last I heard it's now owned by a Chinese company.buyer
beware!

Although there are a couple of small turbine manufacturer's in
the US making 1kW to 2kW machines, I am assuming you want
something reliable so
you may want to steer clear of those. I won't name names here.
And of course there are all those tempting units for sale on
Amazon and Ebayrun
screaming from the room on those.

Slim pickings out there, the small wind industry began a rapid
decline back around 2012 when the PV prices started dropping.
Most of us wind weanies
moved to solar installations to help support our wind habit
and decreased wind sales put many turbine manufacturers out of
business.

Anyway, best of luck on your search and if you find something
and care to run it by me off list please do so!

I once had to rebuild an array of 40 modules that the original installer
didn't scan (didn't even provide an Envoy to the client). One of these
cameras worked out great for me. I have used it several times for various

Agreed! Kohilo and oh so many others were never real projects, only
concepts in search of investors.
There are NO viable vertical axis turbines (VAWTS) on the
marketjust expensive lawn art.

Chris,
 Thanks for the reality check on Kohilo.  I just tried to get info from
them asking for a power curve.  No response.  If a wind turbine
manufacturer can't provide even a rudimentary power curve chart, then it
doesn't work.  I made one for my first homemade wind turbine simply by
watching the anemometer and wattage at different windspeeds for awhile and
writing down the numbers I was seeing and then draw the graph. Wind always
cooperates and gives constantly changing speeds.
