These futuristic creations are home to a myriad of plants and environments, enabling you to travel the world in one visit. It is an unashamed assault on all the senses, combining entertainment and education in a way that makes it a truly unforgettable experience.
The Eden Project
In March 2001, the Eden Project, a massive environmental center in Cornwall, England, opened to the general public. The finished structure is an unprecedented accomplishment -- a giant, multi-domed greenhouse, containing plants from around the globe. The site has already become a popular tourist destination, attracting thousands of visitors every day.
The Eden Project is a sprawling structure built along the side of a deep pit. The structure comprises three biomes, areas designed to represent three distinct climates found around the world.
The Humid Tropics Biome, the most impressive section, is a multi-domed greenhouse that recreates the natural environment of a tropical rainforest. The warm, humid enclosure houses hundreds of trees and other plants from rainforests in South America, Africa, Asia and Australia. The dome is 787 feet (240 m) long, 180 ft (55 m) high and measures 360 ft (110 m) across at its widest point.
From the Humid Tropics Biome, visitors move on to the Warm Temperate Biome. The Warm Temperate Biome, which has the same multi-domed structure as the Humid Tropics Biome, houses plants from temperate rainforests around the world. Like tropical rainforests, temperate rainforests receive a high volume of rain every year, making them an ideal environment for varied plant life. But since they are farther away from the equator than tropical rainforests, they do experience distinct seasons (see How Rainforests Work for details). The Warm Temperate Biome at the Eden Project has varied plant life from temperate rainforests in Southern Africa, the Mediterranean and California.
The final stop in the Eden Project is the Roofless Biome, an open area with varied plant life from the temperate Cornwall area, as well as similar climates in Chile, the Himalayas, Asia and Australia. Visitors can learn about plants that have played an important role in human history by following nature trails that wind over 30 acres (12 hectares) of land.
The creators of the Eden Project see the site as far more than a collection of greenhouses. Their mission statement is to "promote the understanding and responsible management of the vital relationship between plants, people and resources, leading towards a sustainable future for all.” To this end, they have included informational kiosks and artistic installations throughout the biomes. They also hold a number of workshops and special events, all designed to inform people about environmental issues.

From a technical viewpoint, the most amazing thing about the Eden Project is its giant greenhouses. In the next few sections, we'll find out how these monumental structures work and how they were built.
To understand how the Eden Project's super greenhouses work, you first have to understand the fundamental concept of a greenhouse. The most basic greenhouse would be a simple box made out of solid, transparent material, such as glass or clear plastic. When sunlight shines through the transparent walls of the greenhouse, it heats the material inside. Let's consider how this works in a greenhouse with a dirt-covered floor.
Radiation energy from sunlight heats up the greenhouse floor. The floor releases some of this thermal energy, which heats the layer of air at the bottom of the greenhouse. Warmer air is lighter than cooler air (that is, it has a lower density), so the heated air rises to the top of the greenhouse. When the heated air rises, cooler air replaces it at the bottom of the greenhouse. This air becomes heated by the floor and also begins to rise.
This process is going on in our atmosphere all the time. When the sun shines on an area, it heats the ground, which heats the air above it. The heated air rises through the atmosphere, cooling down as it moves upward. This is why air near the ground is warmer than air higher up -- the air near the ground hasn't had as much time to cool.
Then what makes the air in a greenhouse hotter than the atmosphere outside? Simply put, there is a smaller quantity of air that needs to be heated inside a greenhouse. In the Earth's atmosphere, there is a mass of air that extends more than a mile (1.6 km) above the ground (at most points). Even giant greenhouses like the ones in the Eden Project contain only a tiny fraction of this air mass. The greenhouse floor can heat its smaller volume of air much more efficiently than the ground outside can heat all of the air contained in the Earth's atmosphere.
The heated air in a greenhouse rises to the ceiling, is replaced by even warmer air and gradually sinks back to the floor. The circulation path is short enough that the sinking air is still relatively warm when it reaches the floor, and so can be heated to an even higher temperature than before. The ground and air absorb enough heat during the day to keep the greenhouse relatively warm all night.
This is the basic idea behind any greenhouse, no matter its size. Most greenhouses function as a controllable environment for plant life. The plants get all the sunlight they need to survive, but they are not fully exposed to the natural elements.
You can't really control air temperature with a simple glass box, because the amount of sunlight varies a good deal from day to day. To maintain the same optimal conditions year-round, a greenhouse needs additional climate-control features. A typical greenhouse will have some sort of venting system, so air can be released when the temperature rises too high, and some sort of heating system, so the air can be warmed when there isn't enough sunlight. Additionally, a greenhouse needs a plumbing system to keep the ground and the air moist.
As you can see, there are a number of elements that go into constructing a greenhouse. In the next few sections, we'll see how the people who built the Eden Project dealt with these issues.
he Eden Project designers formed this ETFE material into extremely sturdy pillows, each made from three sheets of ETFE foil welded together along the sides, one on top of the other, with layers of air pumped in between them. The air layers provide increased insulation without decreasing the amount of sunlight that shines through. The coolest thing about these pillows is that they are adjustable: On a colder day, they can be pumped up with more air to provide better insulation; on a hotter day, they can be partially deflated to allow more cooling.
Eden's designers attached pillows together to form geodesic domes. In this sort of structure, many flat panels, formed into triangles, pentagons, hexagons or other polygons, are pieced together to form a curved surface. This design is remarkable because none of the individual pieces are curved at all, but they come together to form a rounded structure.
