The problem with renewables is not the power generation, it's the energy storage. Solar and wind generate power intermittently, sometimes when demand for the power is high and sometimes when it's not.
Professor Donald Sadoway, an MIT professor of materials chemistry, thinks his liquid metal battery technology is the energy storage breakthrough we need. It basically takes all the individual cells necessary for a large battery and replaces them with liquid metal, reducing cost and complexity. Lowering the cost of energy storage is necessary if a distributed network of renewable energy, such as...
