At Mercy College in the Fall of 2013 Culhane replaced the two digesters that had been destroyed when his laboratory experiments in room 304 were dismantled and he and Envisaj Mercy Vice President Tasheem Hall filled them with horse manure from the Rockefeller Park stables. One was kept in a shed and the other outside. They both froze solid over the long winter with a polar vortex that kept snow and freezing temperatures until May, and finally started producing gas at the end of May, 2014.
