Stem is a new agricultural system that grows and pollinates plants to produce food without bees. Stem is a response to the ongoing threat of bee extinction, but rather than providing a means to save the bee population, it assumes a worst-case scenario and seeks to design a way to live without them. The project applies existing technologies to artificially recreate ideal ecosystems and natural processes for food cultivation. Within the Stem system, plants grow in automated warehouses on a vertical carousel. The plants are pollinated by robotic arms equipped with a special tool that uses magnetically charged styluses to transfer pollen from plant to plant, thus simulating a process currently performed by insects.
