Sun-grown biofuel This is a bioreactor that recycles
carbon dioxide emissions from a traditional power plant. The apparatus traps
the carbon within ordinary algae cells, which multiply through natural
photosynthesis. This prototype bioreactor, created by GreenFuel Technologies
Corp., was originally tested on the rooftop of a power plant at MIT. More
recently, a larger version was installed at the Redhawk natural gas power plant
in Arlington, Arizona.
