| Interior of South Pole Vegetable Growth Chamber. Image depicts the six nutrient cycling tanks harnessed by their aluminum support saddles |
| Ten of the twelve 1000 watt water-cooled high
light intensity discharge lamps (in center) and environmental ventilation
ducts (far left and right). |
| The Chamber structure is made of a moduler insulated foam and aluminum sandwich that cam-locks together, similar to a walk-in freeze, and is manufactured by Bally Structures Inc. The high pressure sodium water jacketed lighting system is a prototype system developed by Sadler Machine Co. in corporation with University of Arizona’s Controlled Environment Agriculture Center, and NASA’s Advanced Life Support program. The Double Pass growing system is another CEAC / Sadler Machine Co. innovation, allowing the leafy crops to be transported and harvested in the S.P.galley, maximizing space utilization, and keeping the roots from plugging the drains. The web based computerized control system was manufactured by Argus Controls, and allows the chamber to be operated and accessed from anywhere in the world. |
