While i sit smoking my pipe knitting my endless scarf. Come with me on a journey of self discovery, revelations and incredulous mind blowing snippets of today's contemporary brain. A view through the looking glass. An opening of the bell jar if you wish. Turning the mirror to reflect on very nature of the brain and essentially ourselves.
A system proposed by researchers at MIT recycles materials from discarded car batteries — a potential source of lead pollution — into new, long-lasting solar panels that provide emissions-free power.
The system is described in a paper in the journal Energy and Environmental Science, co-authored by Profs. Angela Belcher and Paula Hammond, graduate student Po-Yen Chen and three others. It is based on a recent development in solar cells that makes use of a compound called perovskite — specifically, organolead halide perovskite — a technology that has rapidly progressed from initial experiments to a point where its efficiency is nearly competitive with that of other types of solar cells.
