Canadian researchers hope algae offers them "la grande solution" to greenhouse gas emissions and the environmental havoc caused by oil extraction in the Alberta tar sands.
The project is called CARS, Carbon Algae Recycling System, and it's backed by a consortium of researchers.
The idea is to grow algae next to a source of carbon dioxide, like a power plant. A number of algae start-ups plan to or are already doing exactly that to "feed" their algae the CO2 they need to grow.
Algae can be used for toxic cleanup as well, researchers tell clean-tech reporter Tyler Hamilton.
