Hello everyone. You may be able to tell by the lack of understanding surrounding my following message that I am no scientist, and I realize that this is a speculative, vauge idea, if not a bit of a pipe dream. However, it is something I feel should be expressed, so please bear with me...
The idea is based on the fact that blue green algea, or cyanobacteria, is the most efficient photosynthesizer on earth (or so I remember reading somewhere). Here's a related factoid, from Wikipedia:
Algae and other monocellular organisms
From a 2010 study by the University of Maryland, photosynthesizing Cyanobacteria have been shown to be a significant species in the global carbon cycle, accounting for 20–30% of Earth's photosynthetic productivity and convert solar energy into biomass-stored chemical energy at the rate of ~450 TW.[7]
...So, if this is such a powerful consumer of CO2, why not use that to our advantage?
Could it be that the 'trick' would be getting enough algea, in an environment where it could flourish, high enough into the atmosphere that it could eat away at the excess carbon? Is it at all possible to create a synthetic, gas permiable membrane suitable to house this environment? Even if this membrane exists, how could we lift such heavy devices into the upper layer of the troposphere, in the amounts necessary to make a dent in the damage? Admitidly gaining in farcicality, could it be possible to "anchor" these balloon/homemade cells to the weighlessness of the upper atmosphere, or space, for that matter? I've tried brainstorming other ideas that could do this, such as kiting, helicoptering, ect.. This all derived from a thought I had, for blimps, that were basically huge floating chia pets (ha ha).
I look forward to reading some responses, but like I said, I just wanted to get that out there. Thanks for listening.
