This is hilarious

Like many start ups, it's the scaling of production from the lab to industry. They need financial backing, and not many of them get it. The majority of the turbines in the video were in the validation stage. The majority would be unaffordable for home consumers until economies of scale take effect.

I say, do you think some will go “puff”?

I would absolutely agree with you, except for the last sentence. Wind turbines need a clean airflow. The devices sold as "urban" or "rooftop" are snake oil. There are so many studies on the need for clear air flow, it's amazing that, even now, every now and again, yet another promise of making use of what seems like power-filled winds in urban areas arises, never to come to fruition, because Physics

this is what happens if you have wind, but not clean airflow...

Hah! That looks like an AIR module, very popular about 20 years ago, right up to the time when the wind piped up, when it screeched like a banshee. They were also well known for burning out. There's one in the shed, sans blades.
But your point is well made. Maybe this person thought the trees caused the wind.
