Green Roof Resource

While reading a special issue of Scientific American (September 2005), I came across GreenFuel Technologies, a company based in Cambridge, Mass that seeks to mitigate air pollution through the use of algal photosynthesis. They place bioreactors on the rooftops of power generating facilities to capitalize on natural sunlight to convert the CO2 generated at these facilities into algal biomass. The idea is then to collect the algae from screens and use the biomass as fuel. An interesting concept that is also being explored at Ohio University’s Ohio Coal Research Center.
