Wow these scams surface year after year.
<div>First -vertical axis wind gens are only half as efficient as a horizontal axis shaft wind gen due to the resistance of the half that is spinning against the wind( drag). Therefore vertical axis generator needs to be twice as efficient or receive significantly
higher the wind. </div>
<div>Second -the forces on vert axis lower bearings are ridiculous and will wear & age very rapidly.</div>
<div>Third -the available wind at ground or even roof top level are gusty, unstable, & varying in speed which make the regulator (if there are any) struggle to engage the power on the without stalling the blades.</div>
<div>Forth. - Having installed many wind gens over my early years has taught me many hard & fast rules </div>
<div>1: location, location, location just because you want a wind generator is your location appropriate. The higher your generator is the more power you can produce. Height matters big time.</div>
<div>2: Seasons - I get calls every spring for wind gens because spring is the windiest season in most locals. When I enquire they admit that the 3 other seasons are pretty still.</div>
<div>3 : Obstructions - you need to be a minimum of 25-30’ higher than any object (trees, buildings, etc)that will influence the wind in dominant wind directions or any direction. Also what will local zoning if any allow?</div>
<div>4 : Maintenance / service life : Just like our bodies, vehicles, houses, tools they will need servicing. This is a mechanical device who will service this installation?</div>
<div>5: Sound - go visit an installation typical of your situation in a Good wind speed. Listen & be critical, wind generator sounds are cyclic & continuous NOT like leaves or grasses which tend to be random sounds.</div>
<div>6: DONOT MOUNT A WIND GENERATOR ON A HOUSE! I did this and in a good blow at 30 mph the harmonics generated ( with factory approved supplied vibration isolation) make the house sound like it is suffering a really painful orgasm. DONT DO THIS!</div>
<div>7: Lightning protection : if it looks like a lightning rod guess what? It is a lightning rod!</div>
<div><br>
</div>
<div>Please do not get me wrong ; I love wind generation but only in appropriate locations, correctly installed & at appropriate heights, with safe methods to lower for service, & where the sound will not cause issues with neighbor’s & family. </div>
<div>Bad installations are only bad advertising.</div>

<div>There is no way a $1000 machine can generate up to 9kw of power. And a 9kw genny weight would buckle the metal pole stand it supposedly is compatible with.</div>

I know enough to be highly suspicious, and I won't be touching this unit myself either way, but I'm just curious if anyone knows anything directly about this specific one. I'll be advising this person not to get his hopes up if he does decide to try it out,
and that I am suspicious, but if anyone has anything more specific, I'd love to hear about it so I can give better advice.</div>
