On BBC Radio 4 - 'Inside Science' http://www.bbc.co.uk/programmes/b053bxy1 listen from 7 min 38 until 14 min Interview of Prof. Philp Davies, from Aston University.
"Desalination to produce fresh drinking water is on the rise, but the bi-products of the process - acidic brine and carbon dioxide, are a growing environmental problem. Adam Rutherford talks to Dr Philip Davies who's devised a new idea for treating brine from desalination plants that could help curb carbon dioxide emissions and go a long way towards addressing acidification of our oceans." As far as I understood the process: "Cook" brine from water desalinisation plants with solar energy, precipitate MgO then produce Mg(CO3)2 and capture carbon dioxide, and at the same time remove HCl acidity from the ocean, send it to olivine or basaltic rocks inland where it is neutralised in short timescales... Global result: ocean acidity reduced and some CO2 captured -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
