ITER: 'Where the Sun Will Be Re-Born on Earth'

Long-time Slashdot reader rinka shares an article about "the place where the Sun will be re-born on Earth":The world's best scientists are trying to create a 'miniature Sun' on Earth to tap its fusion energy, costing over €20 billion... [G]lobally ITER is the most expensive science project on Earth ever to be undertaken in the 21st century. The total weight of the ITER reactor will be about 28,000 tonnes... Being made collaboratively by USA, Russia, South Korea, China, Japan, European Union and India as equal partners or participating in this mega effort are countries that together hold 50% of the world's population accounting for about 85% of the global GDP... Dr Mark Henderson, a scientist at ITER, said, "This place to me is the coolest place on Earth, because here in the near future we will have a little Sun on Earth and it will be a 150 million degrees Celsius so it will be the hottest place on Earth, ten times hotter than our Sun...." The project is a herculean effort and operations are expected to start by 2025. Later a full scale electricity generating unit called the DEMO reactor is scheduled to be completed by 2040... On being asked how much carbon dioxide the main culprit for global warming would be released from the ITER project Dr Luce quips "only the carbon dioxide the scientists exhale". The radioactive substances generated from reactions would be the sort that can die off in a hundred years. Its ultimate goal is to create "an unlimited supply of clean energy."
