Last night’s episode of Eureka, “What About Bob?” centered on Lab 27, a huge biosphere carved out of the rock underneath the Global Dyanmics research facility. The biosphere is a completely enclosed artificial ecosystem — apart from energy and information, nothing is supposed to come in or out of the biosphere, not even air. All of the food, water, oxygen and so on needed by any inhabitants of the biosphere must be produced by biological processes that recycle every ounce of waste. Like most real-life attempts to construct biospheres, Lab 27 was built for the sake of research that supports human exploration of space.
