A new method has been found by Pacific Northwest National Laboratory scientists to capture geothermal energy from lower temperature energy sources.

In related geothermal news, a new study by NYU Stern Professor Melissa Schilling found that geothermal is producing the greatest efficiency returns per R&D dollar invested, with wind in second. Solar energy is quite a ways behind, and fossil fuel efficiencies are stagnant, if not dropping, despite getting a huge amount of the R&D budget.
