text: Art at The Core The Core is also home to art exhibitions throughout the year. A permanent installation entitled Seed, by Peter Randall-Page, occupies the anteroom. Seed is a large, 70 tonne egg-shaped stone installation standing some  tall and displaying a complex pattern of protrusions that are based upon the geometric and mathematical principles that underlie plant growth.
  Environmental aspects
  The biomes provide diverse growing conditions, and many plants are on display.
  The Eden Project includes environmental education focusing on the interdependence of plants and people; plants are labelled with their medicinal uses. The massive amounts of water required to create the humid conditions of the Tropical Biome, and to serve the toilet facilities, are all sanitised rain water that would otherwise collect at the bottom of the quarry. The only mains water used is for hand washing and for cooking. The complex also uses Green Tariff Electricity – the energy comes from one of the many wind turbines in Cornwall, which were among the first in Europe.
  In December 2010 the Eden Project received permission to build a geothermal electricity plant which will generate approx 4MWe, enough to supply Eden and about 5000 households. The project will involve geothermal heating as well as geothermal electricity. Cornwall Council and the European Union came up with the greater part of £16.8m required to start the project. First a well will be sunk nearly 3 miles (4.5 km) into the granite crust underneath Eden.
