Geologists in Iceland are drilling directly into the heart of a hot volcano.
Their $20m project will lead to boreholes that could ultimately yield 10 times as much geothermal power as any previous project. It is hoped the endeavour will also reveal more about the nature of mid-ocean ridges where new ocean floor is created. Twenty years ago, geologist Gudmundur Omar Friedleifsson had a surprise when he lowered a thermometer down a borehole. "We melted the thermometer," he recalls. "It was set for 380C; but it just melted. The temperature could have been 400 or even 500."
Hydrogen future
Some 90% of all homes in Iceland are heated by geothermal energy; and a number of power stations are also producing electricity from steam at around 240C, extracted from boreholes between 600 and 1,000m deep.

Ich muß zugeben, daß diese Art der Energiegewinnung mir sehr viel besser gefallen würde als Windräder, die erstens die Landschaft verunstalten und zweitens nur dann Energie liefern, wenn Wind weht - und letzteres deckt sich nicht unbedingt mit dem Zeitpunkt, zu dem Energie gebraucht wird ....
