Geoengineering simulation lets us play with the future

Wherever you stand on geoengineering — whether you think it’s our only chance of survival or a fast track to extinction — we should at least consider the idea. As I argued last year, just studying geoengineering could teach us a lot about the climate and just talking about it could ease some lingering political tensions around climate change. So in the spirit of keeping all options on the table when it comes to preventing a climate catastrophe, check out this interactive geoengineering simulation from the Geoengineering Model Intercomparison Project. It lets you look at what global temperatures could look like between 10 and 50 years from now, if we decide to jump down the geoengineering rabbit hole. Here are the specifics from Slate: This interactive shows temperature…

Invisibility cloak might enhance efficiency of solar cells

Success of the energy turnaround will depend decisively on the extended use of renewable energy sources. However, their efficiency partly is much smaller than that of conventional energy sources. The efficiency of commercially available photovoltaic cells, for instance, is about 20 percent. Scientists of Karlsruhe Institute of Technology have now published an unconventional approach to increasing the efficiency of the panels. Optical invisibility cloaks guide sunlight around objects that cast shadows on the solar panel.
