World's First Magma-Based Geothermal Energy System 161

Lucas123 writes: "The Iceland Deep Drilling Project (IDDP) announced it broke through to the Mantle and created a superheated steam pipe capable of producing power at the nearby Krafla Power Plant in Northern Iceland. The system was operational for several months until a malfunctioning valve forced its closure. The IDDP, however, plans to either reopen its first magma-based geothermal bore hole (PDF) — IDDP-1 — or drill another one at Reykjanes. While the IDDP-1 is not the first bore hole to reach the planet's magma, it is the first time an operation has been able to harness the mantle's heat to produce a steam pipe that could power a plant."

    Iceland's National Energy Authority has created the world's first magma-based geothermal energy system after drilling 1.3 miles (2,100 meters) through the Earth's crust.

    Could they have actually reached the mantle that close to the surface? I would believe they tapped into a volcano, but mantle doesn't sound right. Crust there is something like 15 km []??

Try `stty 0' -- it works much better.
