Iceland Seeking 'Supercritical Steam' For Power Source (bbc.com)

New submitter FatdogHaiku writes: Already getting over 25% of its electrical power from geothermal sources, Iceland hopes to break new ground using "supercritical steam" from a 5 km deep borehole. Is it just me, or does this sound like the start of a movie where everything that can go wrong does in fact go wrong? It's not like they are new to the tech, but working with geologic sources at 450C to ~600C is a new ball game for anyone. It should be noted that Iceland also uses direct geothermal for most of its space heating. "In this area at Reykjanes, we typically drill to 2km or 3km depth to harness the steam, to run power plants and produce clean, renewable electricity," explained Asgeir Margeirsson, CEO of the Iceland Deep Drilling Project (IDDP). "We want to see if the resources go deeper than that." The "supercritical steam" holds more energy than a liquid or a gas. The team wants to bring it up to the surface to convert into electricity, as they believe it could produce up to 10 times as much energy as the steam from conventional geothermal wells.

    You've obviously never watched the History Channel. It reports accurate and verified claims about this sort of stuff daily.

    " The worst kinds of dying seem to be where your body or mind is slowly falling apart with increasing pain and incapacitation while taking a really long time to actually kill you."

    That's called "life after the age of 35". Yet I see no serious research into what aging is and how to stop or reverse it.
