Iceland's volcanoes could power the UK: but at what cost?

Comment

The hot rocks project in Cornwall 20 years ago failed, due to excess fracking of the ground. A great deal of money was spend drilling extremely deep hole. The excess fracking meant that most the huge volume of water pumped down one hole was lost. Very little hot water returned to the surface. A similar scheme is being discussed near the Eden project, but again vast amounts of water are required, basically flooded clay pits. I think it has stalled due to funding being withdrawn. I believe the hot ground in the UK is very deep. I guess it a lot closer to the surface in Iceland. I've been involved in drilling and wouldn't want to spend my own money drilling pairs of very wide, very deep holes in the UK for the water to vanish and the scheme fail.
