Technology often stands on the shoulders of prior discovery. In the energy field in particular, there are precious few killer apps -- ideas that supersede earlier methods. New energy technologies tend to develop slowly and spread at a snail's pace. It takes time and money to accomplish small improvements, and even more of both to spread those improvements across the energy system.
