'Exponential Spin-up' In Geothermal Energy Projects Brings Hope for Green Power
Earth's core "burns with an estimated forty-four trillion watts of power," the New Yorker reminds us — enough to "satisfy the entire world's energy needs" with a power source that's carbon-free, ubiquitous — and unlimited. (Besides running 24 hours a day, one of geothermal energy's key a...
In 2005 one research team calculated that just 2% of the heat just four miles underground in America "could meet the entire country's energy needs — two thousand times over," according to the article. So their new article checks in on the progress of geothermal energy projects around the world, including a Utah company using a diamond-bit drill to dig nearly a mile into the earth to install a 150-ton steel tube surrounded by special heat-resistant cement — all to create "a massive straw" for transporting hot water (and steam). If scientists can do that, however, next-generation geothermal power could supply clean energy for eons... At 6:15 P.M. on May 3rd, cement had started flowing into the hole.
