A presentation delivered this week at the TED 2009 conference demonstrates how you can “grow” fresh air indoors with just three varieties of plants. The discovery was the result of 15 years of testing at Paharpur Business Centre and Software Technology Incubator Park (PBC™ - STIP) in New Delhi, India, an eco- friendly oasis for businesses avoiding polluted air.
