File this under: oh man, this is really friggin’ cool. In case you aren’t aware, there’s a giant sea of really, really hot stuff floating around underneath the surface of the earth. If tapped into, it has the potential to be a geothermal power source. So why isn’t it being tapped into and used?

That’s the question asked by an Australian study, which determined that only 1 percent of Australia’s geothermal power potential could supply the country with 26,000 years of energy. That’s like, longer than the crazy Christians think that the earth has been around for!

Apparently, the only difficult part of the plan is getting the power out of the ground. In a report that the Australian Geothermal Energy Association recently produced, all of the details are explained. Workers would have to drill 2.8 miles into the ground to reach the hot magma, which would reach 20 percent of all electricity demands using this system. It is estimated that it would cost $10.45 billion and take 10 years from start to finish, but once the initial cost and time is laid out, there’s clean and free energy coming up from the ground. Not bad, eh?
