check it out, I guess. Could be an enormous improvement to wind turbines, eliminating many of the objections (footprint, bird kills, etc.)
and, con,
oh come on!
the negative, no what they are calling negative effect of wind turbines
like there are no other birds dying up there in the sky? all done by turbines??
There are a *lot *of “innovative” wind turbine architectures that come down to pure bullshit, that anyone with an ME or Aero degree can determine easily. This site is great for debunking them. But in the meanwhile, they’re good for attracting “investments” from the greentech VC community.
I’m not sure what you’re trying to say here, given the lack of complete sentences, but it sounds like you’re trying to downplay the lethality of turbines to native bird populations, which is actually a problem. The first incarnation of the Altamont wind farm in California was responsible for thousands of bird deaths, including dozens of golden eagles, annually:
The farm was closed down and is being re-opened a few at a time, as they replace the lower, faster turbines with taller, slower ones that the birds (a) fly under and (b) can see/hear coming and get out of the way of.
“Vortex”, “magnets” and “green”; oh boy, the three words at the top of my “This is probably BS” checklist.
Those same wind current areas that are so favorable for wind turbines happen to be favorites of migrating birds. The birds are flying at a height where they aren’t wary of large predators bigger than a hawk so have no instinct to avoid any large moving object. A bus sized rotating blade just doesn’t ping their radar.
In a past career I evaluated generation options for utilities and this issue is quite real.
Lack of complete sentences…oh well, I do my best. I never claimed I had Phd in English. 
So I guess all those planes in the sky have not killed any of our winged creatures? :eek:
I suppose you support not cutting down trees
Plastic bags
etc
Do you even recycle? 
we’re taking wiki for gospel now? You’ve got to be kidding me :o
So in short, I don’t complete sentences, I downplay the deaths of SOOO many birds
and I like smilies…cheer up man, or woman, you don’t have to read my half sentences…tee hee
I’m not sure why I’m responding to this but what the heck.
It appears as if you take issue with conservationists’ approach to wind turbines and birds. That’s fine. There’s a zillion birds out there and you may have a valid point about bird kills.
It doesn’t matter what I as an engineer think about the conservation issue. If the greenies win the war I still have to follow their rules. There is a big enough outcry over birds and turbine blades that the researchers and designers have to examine alternatives.
Wind turbine blades DO kill birds as well as airplanes, jets, and I’m guessing - coming soon to your neighborhood - drones. Does it mean we throw up our hands and quit? No, we weigh the good and the bad about any design technology and explore better alternatives.
For the record - I personally think that the technology mentioned in the op has a slim chance of providing a cost effective solution.
But go ahead and knock yourself out taunting people who are presenting logical replies to your posts. It’s not like this place is about fighting ignorance or anything.
How many birds are killed by the pollution from fossil fuel power plants? Compare that to the number killed by windmills and that tells you how to consider the bird issue.
Wind energy isn’t all that practical, it requires large optimized windmills to compete with the cost of fossil fuel energy production. However, reductions in construction cost and maintenance could make some of the alternative wind generators more practical over time, but those same improvements are likely to benefit the conventional wind generators just as much. We’re likely to see the same kind of horizontal access long blade rotors remain the primary type of wind power generation for as long as wind energy is practical at all. The exception might be small household type windmills akin to the old farm windmills, not all that efficient or practical, but appealing to the ‘off the grid’ type.
