      It seems you are talking about GreenFuel Technologies on MIT

      There seems to be a new development as it can be seen on
      "Fighting factory CO2 emissions with cyanobacteria"

      It would be very interesting to get more info on these projects. The
      problem here unfortunatelly are patents.
