The green sludge that has clung to docks, boats and buildings throughout the old city of Venice, Italy is slowly becoming a saving grace instead of a nuisance.
Recently the city of Venice announced a 200 million euro project to build the first algae-fueled power plant.
“The algae will be cultivated in laboratories and put in plastic cylinders where water, carbon dioxide, and sunshine can trigger photosynthesis. The resulting biomass will be treated further to produce a fuel to turn turbines. The carbon dioxide produced in the process will be fed back to the algae, resulting in zero emissions from the plant.”
