Hot Rock Schemes
In addition to using geothermally heated aquifers, Hot-Dry-Rock geothermal technology can be used to heat water pumped below ground onto geothermally heated rock. Starting in 1977, trials of the technology were undertaken at Rosemanowes Quarry, near Penryn, Cornwall.
In 2008 a planning application was submitted for a hot rocks project on the site of a former cement works at Eastgate, near Stanhope in County Durham. The geothermal plant will heat the UK's first geothermal energy model village.
In 2010 planning permission for a commercial-scale geothermal power plant was granted by Cornwall Council. The plant will be constructed on the United Downs industrial estate near Redruth by Geothermal Engineering Ltd. The plant will produce 10MW of electricity and 55MW of renewable heat.
On 18 December 2010 The Eden Project in Cornwall was given permission to build a Hot Rock Geothermal Plant. Drilling began in 2011 with electricity being produced from the second half of 2013. The plant will be on the north side of the Eden Project, a showcase for environmental projects at Bodelva, near St Austell. It should produce 3-4 megawatts of electricity for use by Eden with a surplus, enough for about 3,500 houses, going in to the National Grid.

Famous quotes containing the words hot, rock and/or schemes:
“As a bathtub lined with white porcelain,
When the hot water gives out or goes tepid,
So is the slow cooling of our chivalrous passion,
O my much praised but-not-altogether-satisfactory lady.”
—Ezra Pound (1885–1972)
“Men are afraid to rock the boat in which they hope to drift safely through life’s currents, when, actually, the boat is stuck on a sandbar. They would be better off to rock the boat and try to shake it loose, or, better still, jump in the water and swim for the shore.”
—Thomas Szasz (b. 1920)
“Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.”
—James Conant (1893–1978)
