Closed Loop Plant system

One of my classes this semester is working on creating speculative habitat systems for plant life on Mars.  Our recent project was to create a closed loop system. My team decided to work on a “Vertical Plant Parfait” in which three different biomes can live symbiotically in a glass container. On the top we have a plant/photosynthesizing layer, the middle is fungi/decomposing layer, and the bottom is the algae/water layer.  We have sensors to detect health of each layer, and a pump runs through the system to provide nutrient/water to the plant and fungi layer. A longer writeup can be seen here.IMG_2371

Plant hammock — suspends our plant while allow organic matter(dead leaves) to pass onto decomposing layer.

How did we get our shelving through the jar? We made some “hinged” laser cut pieces. This piece was for our fungus layer and has window screen material layered on the top and bottom. IMG_2388

Algae was pumped in at the end.

Team Member George made a cool Slackbot for our plant! You can ask for a picture!
