The goal of the Biobulb is to create an ecosystem in a jar that emits light. The ecosystem will consist of several different microbes, each of which plays a role in nutrient recycling and population control.
This ecosystem can be closed and will sustain itself without the addition of outside materials, except for light. In this video, a group of Frontier Fellows at the Wisconsin Institute for Discovery describe the process of creating the biobulb in more detail.
To help raise needed funds for the project, the group has shared information on the RocketHub web page. You can go to rockethub.com and search "biobulb" to see the page.
