Time to go on the record

28. It's better than sitting and stating there's nothing we can do...

We need to get rid of about 545 gigatons of CO2.

Begin list of givens:
-balloon 200 ft radius
-balloon is filled with methane
-balloon uses either PV solar panels, or solar fired thermocouples
-balloon lifts 10 industrial cryo chillers
-balloon has seawater mineral extractors
-balloon has chemistry lab
end list of givens...

-volume = 200^3 *4.19 = (roughly) 32,000,000 cubic feet
-weight of gas= 32,000,000 *.018 (methane) = 576,000 lbs = 288 tons
-lifting ability = 32,000,000 *.054 (methane) = 1,728,000 lbs = 864 tons

-cryo chillers (alibaba.com will sell them) weigh about 5 tons, use 5 KW, and produce 6 tons of Dry Ice per day, and collects Methane
-10 chillers will create 60 tons/day = 21.9 Kilotons of Dry Ice/year

-extract magnesium from sea water (Norton's encyclopedia, or Zumdahl's, your choice)
-set burning magnesium on top of the dry ice->this creates Graphite or Grapheme
-use either of the above in a sheet depositor
-build new balloon out of the sheets
-fill with collected methane.

Use exponential growth to create a building cycle (1 balloon per balloon per year)

Problem solved!

Seriously, isn't trying to fix the problem a damn sight better than sitting around and saying nothing can be done?

That's the reason I never read the "New Wave" garbage faux-SF
