Biosphere 2

Biospheric Design’s most famous design project is the Biosphere 2 Project, a magnificent laboratory for the study of global ecology. This 3.15 acre miniature airtight world is sealed on the bottom by a stainless steel liner and on the top by a steel and glass space frame structure. Inside the laboratory is a 850-square mile coral reef, a 450 square mile mangrove marsh, a 1,900 square mile Amazonian rainforest, a 1,300 square mile savannah grassland, a 1,400 square mile fog desert, a 2,500 square mile tropical agriculture system with farm, & a human habitat with living quarters, offices, & recreational spaces. Heating and cooling water circulated through the biosphere in independent piping systems, & electrical power was supplied to the Biosphere from a natural gas energy center, located outside Biosphere 2, through airtight penetrations.
