Throwing Water In Volcanoes Could Generate Energy, Scientists Say

Mila Luleva — Mon, 17 Nov 2014 10:08:26 +0000

In a search for alternative means to generate energy, scientists have gone beyond what many of us can imagine. Often the new techniques happen to be far from feasible, or just border-line crazy. The latest such idea comes from US scientists, who plan to throw water in a dormant volcano in Central Oregon and harness […]

Could Fracking for Methane Have Caused the Recent Italy Earthquakes?

Ovidiu Sandru — Mon, 04 Jun 2012 14:06:04 +0000

You probably heard about Italy’s recent earthquakes and their aftermath. While it’s highly possible that the event had natural causes, there is also the possibility that methane extraction facilities nearby the epicenter have something to do with it. They employ a method called “hydraulic fracking” to crack the rocks beneath the soil by means of […]

How Old Oil Wells Could Become Geothermal Energy Sources

Ovidiu Sandru — Thu, 24 Nov 2011 10:10:27 +0000

One of the main costs when harvesting geothermal energy is the digging itself. Just like oil wells, geothermal wells have to be several kilometers deep, because temperature rises along by 50 degrees Celsius with every kilometer. This is where abandoned oil wells could help generate clean electricity. A team of researchers from the Chinese Academy […]
