In addition to being a clean energy source without any greenhouse gas emissions, geothermal is  dependable source of power.A new method for capturing significantly more heat from low-temperature geothermal resources holds promise for generating almost pollution-free electrical energy. The approach uses  nanostructured metal-organic heat carriers, or MOHCs, which boost the power generation capacity to near that of a conventional steam cycle…
