Electron Flow and Evolution of Life: Our target is to find the role of electrical current for emergence and evolution of life; how nature has utilized the electrical current from billion years ago, and its relevance in our modem technology, such as fuel cell, battery, voltage amplifier, and thermoelectric conversion. Knowing the evolution of this in nature would be a nice guidance to realize sustainable human ecosystems.
