Solar cells, all over commercial buildings, residences, cars--and clothing?

Further proof, I think and hope, that one day--and one day sooner than we thought--we'll be able to have solar cells all over our commercial buildings and homes in order to generate clean, renewable, solar electric power. Then we could also do away with the need for big power companies and, more importantly, electricity from coal-fired power plants, their very dirty air pollution and even nuclear power plants. This article today: Scientists develop ultra-thin solar cells "Austrian and Japanese researchers on Wednesday unveiled solar cells thinner than a thread of spider silk that are flexible enough to be wrapped around a single human hair. The thin-film device, comprising electrodes on a plastic foil, is about 1.9 micro-metres thick, a tenth the size of the thinnest solar cells currently available, the researchers said." One micro-metre is one millionth of a metre (3.3 feet).

"'The total thickness of this device is less than a typical thread of spider silk,' the researchers said in a report carried by online science journal Nature Communications. 'Being ultra-thin means you don't feel its weight and it is elastic,' said one of the researchers, Tsuyoshi Sekitani from the University of Tokyo. 'You could attach the device to your clothes like a badge to collect electricity (from the sun)... Elderly people who might want to wear sensors to monitor their health would not need to carry around batteries,' Sekitani told AFP." This is a pretty incredible discovery and revelation. This can make progess for clean electrical power that much sooner and more likely. As ever, here's hoping.
