Geothermal energy

How to see through rock

It’s costly to drill deep into the ground for thermal energy. So you may want to know what’s going on down there. Mathematicians can help.

Harnessing the heat below

The deeper you drill, the hotter it gets. This video shows an example of how to recover geothermal energy from hot bedrock.

Glaciologists luck out with seismograph and video

VIDEO: Against all odds, while researchers helicoptered over Svalbard and filmed a calving glacier, a seismometer recorded the activity. The data they registered can help in detecting calving episodes and understanding the dynamics of glacial activity.
