Wooden mortice and tenon joint at the Eden Project in Cornwall county England UK
The biome structures are made up of connecting hexagons, pentagons and triangles, forming a sphere. The individual hexagonal and polygonal pillows of ETFE consist of three or four layers into which air is pumped by a solar-powered heating system. Once inflated the pillows provide more insulation than glass. In times of exceptionally cold weather they can be inflated further. Each panel can easily support the weight of a human-being is expected to last between 20 and 30 years.
