Check out these fascinating algae-powered public lamps, sent to us as a blogtip sent in from Tony Sherwood: a reminder that solutions to one problem often emerge from an understanding of the fuel, product, and waste from complementary processes.
Here’s a post about these lamps with some links to supplementary articles from Treehugger.com:
French biochemist and Shamengo pioneer Pierre Calleja has invented this impressive streetlight that is powered by algae which absorbs CO2 from the air. We have featured algae-powered lamps before but this one takes out 1 ton (!) of CO2 per year. This is as much CO2 as a tree absorbs on average during its entire life.
It seems to me that this is a pretty amazing idea that could really work and clean the air pollution from urban areas (like parking lots, tested in the video above) and at the same time look good. That said, reducing is still better than restoring, but in the meantime- let’s get this lamp working!
