Nanotechnology Could Save The Ozone Layer

Liz writes "Whilst experimenting with nanospheres and perfluorodecalin, a liquid used in the production of synthetic blood, researchers at Germany's University of Ulm have stumbled across a phenomenon that could ultimately help remove ozone-harming chemicals from the atmosphere. See this article for more details."

Ozone Layer Doesn't Need Saving

[the eric conspiracy]

Bans of CFC's that deplete ozone have already essentially stopped ozone depletion and in fact ozone levels are expected to slowly recover over the next 50 years or so.

Using MEMS to process CO2, CH4 in upper air

[Randym]

Why release gases when we could engineer small micro-devices -- floated aloft by tiny helium balloons -- that would, using catalysts and solar energy while floating about in the upper atmosphere, grab CO2 or CH4 [methane] molecules, collect the carbon (coiling it into a chain of carbon) and split off and release the O2 or H2. Eventually, the devices, weighted down with carbon, would sink into the lower atmosphere where, using RFID technology, they would be collected at various points, cleaned and relaunched until the levels of CO2 and CH4 had sufficiently declined. The pure carbon could be reused in industry.

Problem: if too small, they may be mistaken for food by birds as they drift down.
