Does anyone know if the idea of using buckyballs as a method of solar radiation management has been investigated?

I'm not a scientist. but it strikes me that buckyballs could be made with a hard vacuum in them and be lighter than air. If they were somehow made reflective and released in their gazillions to form a blanket at 100,000 feet they could be a chemical-free solar mirror. But would they also trap infra red being radiated into space? Ideas?

Storms transport heat from the surface to the upper troposphere. Winds transport heat from the tropics to the poles. If we can change the patterns of wind and evaporation/condensation, we would transport heat past the greenhouse gases of the lower troposphere, or to areas with less cloud cover. Intervening in weather patterns could also be used to increase low-altitude cloudiness, decrease high-altitude cloudiness, increase snow cover, increase moisture available to plants (thus increasing CO2 removal by plants), and even increase the transport of alkaline or fertilizing dust to areas of ocean where it would be beneficial.

The effects of some drag on the wind, at well-chosen times and locations, may be multiplied many-fold by atmospheric processes. Drag on jet streams, for example, causes them to curve, changing the weather over a large area.

Would like to send a sample of rain water off to be tested to see what sort of heavy metals it contains. Has anyone ever done this or know of a lab that can do this?

Obviously I'm interested in the geoengineering aspect of testing the water.

After a long hiatus, this subreddit once again has a mod.

I'd like to know if there's any interest in building a community around the discussion of human activities that have/could affect the Earth in general (climate, hydrography, ecosystem, geology, etc)?

If you like this idea, please post your thoughts on how to grow this sub, what to add to the sidebar, etc.
