Smoke stacks are a reality of the modern world, and it's costing companies a fortune to comply with the laws preventing air pollution - cleaning the nitrogen oxide (carbon dioxide might soon be regulated too) out of the smoke.

On top of the power station at MIT is a "green triangle" that uses algae to clean the pollutants from the smoke, some 80% cleaner. This algae, along with the sun, turns the nitrogen oxide and carbon dioxide into organic carbon and hydrogen. The savviest companies could also use that hydrogen as a renewable energy source.

The algae feeds on the bad stuff at a fraction of the cost it takes to clean the smoke using the current methods. Yet another example of how green technologies can improve the way we do things (i.e. a better method for preventing air pollution) and save money (i.e. make a company more profitable). So why aren't companies using this yet? They will; they've only just begun to think this way, give them a little more time.
