This may be a dumb question, but if we're collecting volcanic rock, could we not tap into geothermal energy from the volcano to get cheap energy?

- rogerkirkness 3y agoThe argument is basically that we will need extra energy to go towards carbon capture one way or the other. Energy in, carbon reduced. This may or may not be a feasible way to do that.
- pacaro 3y agoIt seems reasonable to assume that many places where there is easily accessible volcanic rock are also places where geothermal is possible, but the connection between rocks like basalt and volcanoes can be more temporally distant that you may be thinking. If I go to a beach in the US Pacific North West, I can pick up basalt rocks/boulders/pebbles, but they last were in contact with an active volcano millions of years ago (approx 12mya is the usual number given locally, if memory serves)
