One of the joys of growing up in 1980s London was to witness how the grim concrete monoliths of the 1970s were slowly displaced by towers of glittering glass. Particularly in the City and Docklands, where money was no object. But there was one hidden problem: althoughthese buildings looked modern, they still consumed immense quantities of old fashioned coal and oil to heat, with fateful consequences for us all. Certainly, you can tack on solar panels here and there. But the aesthetics and very shape of the buildings mean that the power they throw out will not come within shouting distances of keeping these buildings’ inmates, healthy, wealthy and warm.

But what if you could turn all that glass itself into solar panels? What if every one of those magnificent windows was a brimming source of electricity, producing almost as many watts and amps and volts and electrons as a the real panel on your garage roof. Fortunately the City Solar Project has made just such a breakthrough We have lifted this tiny quote from a really upbeat article by Anthony Cuthbertson of the Independent, to give you an idea of the currents of excitement flowing around this project (oh, please!-ed)

By combining organic solar cells with the so-called “miracle material” perovskite, the scientists were able to achieve an efficiency of 12.3 per cent – close to that of commercial solar cells.[2]

Now, we’ve covered Perovskite a couple of times before on this blog (LSS 12 1 21;13 11 23) so many of you will know all there is to know about it: but we’ve put in a link for those who came to us late. The real point is not just that scientists and engineers are bringing us closer and closer to a cleaner, more sustainable world. It’s that those who say sustainable energy is not possible are starting to look very archaic indeed.
