One energy company is hoping to change the world by producing electricity from the heat found deep beneath our feet. Drilling deep down into the planet's surface is a particularly challenging feat - to date the furthest anyone has gone is around 7.6 miles, which is hardly 'Journey to the Center of the Earth'.
The problem lies in the fact that operating a drill at extreme depths and pressures is very difficult, as is transporting the drilled material from the bottom of a miles-deep hole back to the surface.
While probing what lies deep beneath our feet can provide large amounts of data for scientists hoping to learn more about the interior of the Earth, such endeavours also have another potential benefit in the form of geothermal energy.
