Geosynchonous Circular shaped Mylar fields in space to reduce global warming over specific cities

As I thought more about this I realized there was no way everyone on earth was going to agree to something like this to reduce Global Warming.

However, city by City like New Delhi or large cities in Pakistan or other cities might have a vote of their citizens to put up circular football sized mylar fields in space in geo synchronous orbit to reduce solar heating of their cities in Summers or year around. This could be voted on by cities and therefore not need 7 1/2 billion people to agree on this. So, city by city this could reduce global warming and thereby reduce the effects while generating power from the solar arrays built into the array that then would be beamed down from space for use on earth and pay for the whole thing over a period of time. So, this could be done by people voting city by city not to die en masse in the heat.

However, I'm wondering about what people would do in the winters?

However, that could be solved by louvering the solar array so it could have light go through it sort of like louvred windows do in the winter time so it didn't get too cold. So this array could be louvred for maximum benefit almost like a heating and air conditioning system for cities around the globe city by city which might reduce global warming in summers and help heat cities when needed by solar warmth in the winter time as needed.

Another way to louvre the solar arrays or mylar would be to have the whole circle louvre itself with jets every six months or so or even to have slowly changing variable pitches during the year. However, if it weren't perpendicular to the sun it wouldn't generate as much electricity.

However, I know also you are going to have people complain that solving the problem of heat in cities won't save people who don't live in cities or in farms outside of cities.

But, if cities did this and were successful similar methods could be used other places too.

I was trying to envision what this experience would be on earth and I could imagine a little shadow moving out from a pinprick in the sky. It would be so far away from earth you wouldn't be able to see a single one but it would spread out to great size as the sunlight around it reached earth and create a larger but probably not well defined shadow edge where the sun and the edge met. However, on earth it would be a shadow slowly moving across a city as the sun was at it's zenith during the day.

However, there is another factor the earth's cycles in relation to the sun change with the seasons. So, likely the football sized mylar or solar array would position itself in regard to the hottest times of the year or it would have to move slightly every day or every season to a new location because the sun's declination changes with seasons depending upon where you live on earth.

However, what I'm saying here is there are technological ways for the human race not to go extinct here on earth.

And many of you will think of some of the ways just like I have here.
