From writer Pets Scholtus at Treehugger.com: The amazing, algae powered street lamp!
French biochemist and Shamengo pioneer Pierre Calleja have invented this impressive streetlight that is powered by algae which absorbs CO2 from the air. This lamp takes out 1 ton of CO2 per year. This is as much CO2 as as a tree absorbs on average during its entire life.
What an amazing invention. I hope to see these eco-friendly streetlights on highways as soon as possible.

And thanks to my friend Cameron ‘Telepathy’ Ross for bringing this to my attention
