#2Potent potables?

#3Maybe this could be combined with electric field desalination to make seawater potable:

#4This is really cool in its simplicity and sustainability.
People get obsessed with complex tech (e.g. high energy fusion). Sometimes I think that the ultimate limits of high tech look low tech to the unappreciative.

#6> he imagines [the necessary CO2] would come from power stations and other industrial processes, such as cement-making, that produce the gas in large quantities as exhaust.
IANAC, but it seems like that just exchanges one problem for another. I imagine that most, if not all, of the industrial processes that produce CO2 exhaust gases also result in other gases and particles getting into the exhaust stream, meaning that you'd have to refine/filter the exhaust from those processes to get just the CO2.

#7This is cool, particularly in the simplicity of the approach. Reminds me of how a septic tank works but at a much finer scale with the CO2 augmenting gravity.

#8Seems like a highly elegant solution .. one wonders if this could be used to make better air-breathing rockets ..

I doubt they're suggesting they use the untreated flue gases as the gas in the apparatus. I think they're just pointing out that there are industrial sources of co2, n and that finding a use for the co2 helps with another pollution/waste issue
Re: A way to make water potable using carbon dioxide
#10Nice, other than the necessity of dumping CO2 into the air. I wonder if he tried creating an electric field across the water as some folks have done for desalination[1]. Any pollutant with a net positive or negative charge would be suitably diverted in that way.
