Main Question or Discussion Point
I’m looking to create a self sustaining ecosystem inside of a 4x2’ glass box that could be a totally closed system (with the exception of heat transfer, I can’t really prevent that). The idea is that I would bury it for a year and then dig it up again. In order for that to work I would need a way to generate enough electricity inside of the box to power a small led grow light, but I’m not aware of any way to do that. Is that even theoretically possible? I considered using a syphon to turn a small turbine but later learned that is impossible due to the way syphons work. Any help would be greatly appreciated!
