| In the south-west of Iceland a hole has been drilled to a depth of more than 4200 meters in the heart of a volcano. The plan is to come to a depth of 5000 metres where the temperature of the rock is expected to be between 400 and 500oC. This can be used for energy generation by hot steam. It will then be the world's hottest borehole. |
