A hydraulic fracturing plant.

In my final year in college we had to design a plant that could get natural gas trapped deep down in the earths bedrock and refine it for use in people’s homes. Fracking is a sensitive moral issue, but the plant we designed was pretty awesome! I got an A in the project 🙂
