Large scale capture of CO2 from the atmosphere?
How could one capture massive amounts of CO2 from the atmosphere - what chemical reactions are there that could be used? Obviously there is the risk of reversing the problem of greenhouse gases so much that plant life is at risk, but if the process was limited to just in power stations or in cars - how could one do it?

Check out a recent edition of Scientific American. They have an entire edition devoted to this sort of thing.
CO2 can be sequestered from the atmosphere. It could be trapped using nanomaterials where CO2 would be trapped in a "cage". There are also chemical reactions that can trap the CO2 as salts (carbonates, etc.). But these are not economically feasible.
But in my opinion, the best way to do it is to sequester the CO2 at the point of emission.we manage to reduce SOx emissions in this way, there's no reason why we can't do it with CO2 as well.
We are already pump CO2 into oil wells which has the advantage that as well as getting the CO2 out of the atmosphere it also forces more oil out (hang on that might be a ad thing)
Anyway - I've been thinking about this for a few months now and it fairly easy to turn CO2 into Water and carbon but you need lots of energy - the same about that you got from burning the damn thing. You could use fission reactors to scrub the CO2 out of the air.
The first thing you could do was to ensure all CO2 produced by brewers in the fermentation process was bottled and made into something more useful : like dry ice for example.
There is a lot of CO2 given off during fermentation.
Very simple. Plant trees all over.They will absorb CO2 and give you pure Oxygen in return. Okay?
Replanting lots of tree could do this. The desecration of huge areas of the rain forests is damaging the atmosphere. Trees produce oxygen.
The ocean is already doing this. Global warming is the hot topic now, but up and coming is Ocean Acidification.
The Ocean captures huge amounts of CO2 from the atmosphere.
The end result is H+ levels increase. The real end result is that the ocean will balance out by removing carbonates from structures such as coral reefs and critter shells. Ouch.
Trees are around 1% efficient at changing light energy to plant material. With some incentives, like cellulose fermentation to make biofuels, some genetic engineering could probably be done to make them much more efficient.
