felix said:Icelanders have been heating their houses with geothermal steam for as long as I can remember. (When I first read about this way back in junior school I imagined houses with pipes running out to little geysers in their back gardens.) If we can get our act together and stop throwing valuable heat away then I believe the balance tips in favour of the power station.
Latest I've heard is from a handy little prog on R4 called 'five holes in the ground'
Seems the Icelanders plan to did even deeper holes, use the super steam to power turbines and produce hydrogen fuel cells to export to Ken in London to power the new eco buses.
