Assuming we are able to engineer glow-in-the dark butterflys (or NANO Robots) that poop buckyballs
and that survive and prosper on sulfur and other chemical energy isources within the upper levels of Venus' atmosphere...
How do we then collect and use the buckyballs?
Or do we just let the process run wild and see what happens?
What if the buckyball layer gets so heavy that it compresses the remaining atmospheric layer beneath it into CO2 and liquid O2?
What then???
