Cracking geothermal energy challenge through fracking

That hydraulic fracturing, or fracking, has been used to obtain natural gas is news to no one. But how about using it to get renewable energy? Well that is precisely what a Seattle-based company called AltraRock has been testing, namely using fracking to tap geothermal energy produced from heat down in the earth. The company’s technique starts with modifying rock deep underground to allow water to flow through it. Then by pumping cold water into the rock in just the right way, they attempt to trigger existing fractures to allow more water to flow through, which in turn generates steam that can be used to produce electricity. Perhaps this is another energy solution cracked using fracking.
