Here is a bizarre concept called Urban Sun:

Several questions immediately come to mind:
1. Doesn't our real sun already do this? Just lift the lockdowns/curfews and let us go outside.
2. What would power such a thing? Solar panels?
3. Who died and put these clowns in charge?
Here's a reason why Urban Sun may make sense to TPTB - some of these "architects" (e.g., Bill Gates) are considering dimming our real sun by injecting reflecting particles into the atmosphere to cool the planet. In such a scenario, the building of artificial suns could mimic the beneficial effects of the real sun.
But I don't believe it's possible to predict all the side effects from zany schemes like this. Without a full understanding, they could backfire horrendously.
This situation reminds me of the following dialogue from the 2008 movie The Day the Earth Stood Still:
Professor Barnhardt : There must be alternatives. You must have some technology that could solve our problem.
Klaatu : Your problem is not technology. The problem is you. You lack the will to change.
Professor Barnhardt : Then help us change.
Klaatu : I cannot change your nature. You treat the world as you treat each other.
Professor Barnhardt : But every civilization reaches a crisis point eventually.
Klaatu : Most of them don't make it.
Professor Barnhardt : Yours did. How?
Klaatu : Our sun was dying. We had to evolve in order to survive.
Professor Barnhardt : So it was only when your world was threatened with destruction that you became what you are now.
Klaatu : Yes.
Professor Barnhardt : Well that's where we are. You say we're on the brink of destruction and you're right. But it's only on the brink that people find the will to change. Only at the precipice do we evolve. This is our moment. Don't take it from us, we are close to an answer.
If you recall, Jennifer Connelly's character (Helen Benson) previously told Klaatu that Earth's elected governments were not our leaders - people like Professor Barnhardt were.
We face a similar situation. The UN, national governments, and international organizations (e.g., the WHO) seem powerless to halt the pandemic or address climate change ... and people like Bill Gates, Klaus Schwab, and thousands of scientists and technocrats are attempting to fill the leadership vacuum.
Unfortunately, none of them have the wisdom or experience of Klaatu. How can we trust them to make irreversible changes to our world when NO ONE has any idea exactly what those changes will cause to happen? When and where did they meet to come up with their expansive plans for the rest of us, and why weren't We the People given the opportunity to provide any input to those plans?
