The idea has merit, but it's not quite there yet. For one thing, you will have to physically visit a police department in Estonia in order to get your E-residency card - TWICE.
Once to file an application and then it will take up to 14 days for them to perform a background check. After which you will again have to physically appear at a police station in Estonia.
In the future this can supposedly be done through Estonian embassies but those are not exactly everywhere either.
Reading your post makes me wonder why bug-hunters aren't more cautious about this. Sure the sentiment is good, it is a moral obligation to expose a bug that could be harmful to users.
But if you suspect you could get burned for pointing it out, you can take steps to mitigate it. Anonymity for example. Then again if you are in it for the fame and recognition, getting burned is a risk you are taking out of vanity.
This looks much more difficult to clean, think of all the bugs, birds and sediment that will stick to the INSIDE of that funnel structure. Cleaning the blades of an ordinary wind generator seems much simpler.
On the other hand, if this is as tall as they will get, it seems a lot safer to work on than the current behemoths.
