The Vortex bladeless turbine uses the wind to vibrate instead of spin. That makes it cheaper, quieter, and more reliable than a bladed turbine.

My first question… Does it still create as much energy as the turbines with blades? (It doesn’t).
My next question… What about the birds? I can understand how birds and bats fly into them. The colour is meant to blend into the sky (for human sensibilities, not birds).
As far as noise, we parked right next to one here in Ontario. Turned off the car (the car made more sound than the turbine) and just listened for half an hour. It was very quiet. Out on a backroad, in the middle of nowhere, for awhile we felt apart from all civilization. That feeling of being still after the world has ended.
Without blades the new wind power could be very low maintenance and have far less parts to replace. That’s a good thing.
But, they do produce less energy. The solution offered in the article is to have more of them. Is this practical?
How many can be grouped together before they lose efficiency due to blocking the very wind they rely on? How many land owners are going to want a forest of these on their land? How long will it be before the same people who protested the noise of wind turbines find these have a persistent hum or vibration or some other problem which gives them headaches?
I’m not sure a lot of the complaining about wind turbines is really justified. At least the human complaining.
Bladeless turbines may be less deadly to birds and bats, but we can’t be sure of that.
What will happen with more turbines in the same area of land?
There are no perches for birds. We don’t want to encourage the birds to use them, yet a forest of wind turbines take up space without giving the birds a place to rest.
Of course, the bladeless turbines will also be a colour intended to blend in and not obstruct too much of the view, for humans. Birds may fly into these man made forests and not see what they flew smack into. To a bird a forest of nearly invisible tree stalks without perches or branches waving in the wind to show their location may not work out so well.
Could these ivory towers be made nature friendly at the risk of becoming less tolerated by humans who enjoy the energy produced by them? Could bird houses, bee hives and bat boxes be included? Could they be made mandatory? Would that be unsightly or just unnatural?
