An interesting advance in battery applications

From Stanford University encouraging news, a rechargeable Zinc-air battery would put electric cars into the realm of reasonable practicality, where with lead-acid batteries they are currently not. Stanford scientists develop high-efficiency zinc-air battery Stanford University scientists have developed an advanced zinc-air battery with higher catalytic activity and durability than similar batteries made with costly platinum…

Study says global warming caused by CFCs interacting with cosmic rays, not carbon dioxide

From the University of Waterloo, an extraordinary claim. While plausible, due to the fact that CFC’s have very high GWP numbers, their atmospheric concentrations compared to CO2 are quite low, and the radiative forcings they add are small by comparison to CO2. This may be nothing more than coincidental correlation. But, I have to admit,…
