It's a shame there's no good way to harness that.
- ovis 13y agoAlthough it's admittedly difficult when the higher temperatures are hundreds or thousands of kilometers away, geothermal power plants do in fact harness that.
- dkhenry 13y agoIf I am not mistaken Iceland uses geothermal to a large extent and is very successful in doing so.

- comicjk 13y agoYes, we could use more research in the technical side of that. Right now hard-rock drilling is so expensive that geothermal is only viable where natural circulation of underground water brings heat up from hotter regions.
- blueprint 13y agoIt's important to note the fact that the heat in the core does not exist in isolation of other fields. The Earth is a dynamo system, and the energy in the core is connected to the planet's magnetic field, the energy bound up in its orbit around the sun, and its gravitational field.
- 3am 13y agoIts rotation produces the magnetic field which keeps the solar wind from stripping away our atmosphere and leaving the Earth a dead planet like Mars. We're getting our money's worth.
