Translator II: Grower is a small 'rover' vehicle which navigates around the periphery of a room. It hugs the room’s walls and responds to the carbon dioxide levels in the air by actually drawing varying heights of 'grass' on the walls in green ink. The Grower robot senses the carbon dioxide (CO2) level in the air via a small digital CO2 sensor. This sensor is mounted high on a wall of the exhibition space and sends data wirelessly to the robot. The number of people in an exhibit space breathing in oxygen and exhaling CO2 has an immediate effect on the sensor. My robot takes a reading of the CO2 level every few seconds and in response it draws a vertical line in green ink on the wall. The line height pertains directly to the level of CO2 (and therefore also the people traffic) in the space. The more CO2, the higher the line is drawn - the maximum height being 1ft. Once Grower completes a line, it moves forward several millimeters and repeats the process.
Oxygen Curtain Mae Shaban (RAD: Responsive Architecture at Daniels) 2011 air refreshing, autonomy, organisms, environment, water, sensors, CO2, project, nutrients, algae, bioreactor, plant, carbon, oxygen, design
The curtain integrates an efficient organic living carbon sink into an interior space. The curtain produces an amount of oxygen equivalent to a mature broad leaved tree – it is a dramatically enhanced house plant. The curtain is composed of an array of algae bioreactors. A network of indoor air, power and nutrient supply lines weave the bioreactors into a single membrane. The nutrients are supplied by the building’s waste water. The curtain is nourished by the CO2 from the exhalation of the inhabitants. It is directly responsive to the users and the environment; each module operates autonomously and sensors activate select modules as appropriate to the changing levels of CO2 within a space. The modules then expand and contract with circulating air revealing a mechanic-organic organism that is continuously refreshing the air.
