The shape is not to hard, it is called a troposkein; and is basically the shape a rope will naturally take if you hold both ends together; and let it hang down.
The trick is figuring out how to keep that high efficiency shape from stalling, and stopping.
well I hope they enjoy themselves.
keeps em off the streets and gives them something to do.
My opinion, after having been involved in 'wind energy' for a decade or so is that it's a bad idea.
waaaaaay too many negatives.
for one...if something can't exist without subsidies (stolen money) then we don't need or want it.
for two..energy storage. We need electricity when we need it...not when the wind blows. NEWFLASH..sometimes the wind blows too hard...and the windmills have to be shut down or get damaged. Some times they get damaged anyway.
There are other reasons 'commercial wind' is a bad idea..but those two are enough.
I will be building this from scratch, no subsidies, only my money risked. I have solved the overspeed speed shut down. I have solved the stalling. My off grid (once I pull the meter) house, will have over 21,000 watts of 24 volt battery storage (I have over 7,000 watts already, more to come) that will be charged from a combination of solar, and wind for now. With 2 other research generation methods I will look at after I am caught up a little more.
The tip speed ratio can go as high as six, but is a lot more stable at four to one; so at 25 MPH wind speed, the generators will be spinning at 100 MPH I have located a non cogging 24 volt generator for this assembly to turn, and I already have a 3000 watt dump resistor in case of overcharge. The first wind generator I will put up is a 1700 watt unit that will yield between 450 and 500 watts with our average wind speed.
Actually, the plodders at Sandia labs have published research on the perfect cross sectional shape on a Darrieus rotor.
They don't know how to USE it, but they saved me years of testing, and about four million dollars in testing costs! *
:)oh goody
something no one wants...
Most of the time for sure, LOL! That shape, with that rotor, will harvest about four times the power; with the same sized rotor.
:Dso they say.
is it feasible to manufacture it...'with that shape'?
