During the elections, the idea of energy independence came up a lot. In fact, there was major emphasis put on our nation's ability to pull fossil fuels from the ground. In particular, there was mention of hydraulic fracking and horizontal drilling. But how many of us could easily explain what that process is, and why it may be a way for the country to have an excess in natural gas?
In this week's Untamed Science video Rob explores the basics of hydraulic fracturing via a Skype call with geoligist Dan Bertalan. He explains what they pump into the ground, how it fractures the rock and how that allows natural gas to then come to the surface.
