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.
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?
