<div><div><br></div><div dir="auto">I installed a Superwind 1000 at a mountaintop transmitter site on a 35’ tilt up tower to supplement 4000 watts of solar. That ridge has been tested for a wind farm and the wind speed was wind farm quality. I have data on that site on OpticsRE using a shunt with FlexnetDC. The transmitters site has a continuous 300 watt load and the single wind turbine has produced significant power at night and in stormy weather. The hourly averages for output have been as high as 800 watts and often will carry the 300 watt load for several hours at night. The amount of propane used for the backup generator was significantly reduced, justifying the expense of the Superwind and installation. Figured into the cost savings was the cost of hauling 100 Lb propane cylinders up the mountain on ATV’s and snowmobiles. Had only one down time in 3 years when I’ve storm temporarily froze the blade hub to the nacelle. <div><img src="cid:18a0657a70f63e6a2601" style="max-width: 100%;"></div></div><div dir="auto">John Blittersdorf<br><div class="gmail_quote" dir="auto"><div dir="ltr" class="gmail_attr">On Thu, Aug 17, 2023 at 4:24 PM Roy Butler via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" target="_blank">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><u></u>

record but it's a bit spendy for the size.<br>
They have targeted the commercial field and are doing well with
the railroad and oil and gas industry.<br>
<br>
I tend to forget about it so I hadn't mentioned it before.<br>
<br>
As for VAWTs, there are still no commercially viable models on the
market today. They have a terrible track record.<br>
They look cool, tend to be installed on college campuses and other
highly visible locations, so the general public<br>
thinks that they must be good.<br>

the 1-2 kW range right now is pretty grim - Tons of awful

(NOT) by a 900mm diameter VAWT that seems very popular

all<br>
<br>
Is anyone making a good quality 1-2kw wind machine?<br>

All of my searches come up with nothing. <br>
