» Isaac Berzin, a rocket scientist at Massachusetts Institute of Technology, is creating algae farms to clean power-plant exhaust and create clean-burning fuels. "The cleansed exhaust bubbles skyward, but with 40 percent less CO2 (a larger cut than the Kyoto treaty mandates) and... 86 percent less nitrous oxide. [...] Berzin calculates that just one 1,000 megawatt power plant using his system could produce more than 40 million gallons of biodiesel and 50 million gallons of ethanol a year. That would require a 2,000-acre 'farm' of algae-filled tubes near the power plant. There are nearly 1,000 power plants nationwide with enough space nearby for a few hundred to a few thousand acres to grow algae and make a good profit, he says."
