Not needing as many moving parts is also a cool benefit here.

Wind turbines do in fact kill birds but much less than you'd think, probably more starve every year than getting iced by a wind turbine.


Truly, I mean, it's not like birds don't have eyes and can't see the turbine in their way. tongue.gif


Anyways, this looks like a terrible design, from a point of view of surface area alone, you're wasting huge amounts of material and potential power using those toothpicks.

Very interesting concept, especially seeing how it can be closely packed, wonder what's the kind of density they get out of this?

Conversely, the wind turbines are expensive to maintain and more often than not when I go by them (only a handful of times in a year) most of them are not operational at all.

These look rather low maintenance, which could be their saving grace.

Sure, but I hardly say 30% is HUGE.. its a large chunk, but if they are 50% cheaper to maintain, you end with a net decrease in cost per kWh. The article and video already address that saying you can achieve a higher density, therefor making up for lost production capacity per toothpick.


To address the bird comment, wind farms are becoming a thing and more widely deployed which means the 365,000 birds killed annually by wind turbines will only go up. This will have the added benefit of being deployable in places which traditionally don't have a strong enough sustained wind to support large turbines, while they are likely have a much lower impact on wildlife.

If its cheaper to maintain, costs you less to deploy and the system can create the same amount of power while not disturbing the environment as much, how is that not a win all around?

40% cheaper electricity? Neat! Less material to start with, it seems, plus far fewer parts to be produced or replaced or maintained. The biggest question is just how efficient is it compared to traditional turbines? Watts per square meter (power output per some area of wind farm) and watts per dollar (installation cost, not running cost) are the two big ones.

In my opinion, they are quite befooling since they sound like jet planes 10000 feet up and at the same time are right there next to you. Cycling around them is quite like flying next to planes, if you take your ears as your guide.

I'm sorry, these things are dumb. Vibrating items like this is only going to cause metal fatigue and lower their lifespan and increase maintenance costs.

Also, it would be nice to see these things in a 60mph or even 120mph wind, which is easy to do in the real world ... with bad weather.

Works in a lab is one thing, works for more than 30 days (and hopefully more like 5-10 years) in the real world is another.

Pretty much this.

Plus they didn't give us estimations on how much energy will actually be produced either...

Cool concept but everything else seems to fall pretty flat.

Some went up by my old boss and she hated them. Could hear the woosh sound, then when the sun was setting they'd get really annoying shadows in the entire house and one year almost killed someone by chucking a huge chunk of ice, went through someones windshield that was coming up the road.
