A team of MIT researchers has figured out a way to create a supercapacitor simply by mixing cement, the binding ingredient of concrete, and a fine charcoal product called carbon black together with water.
Better yet, this mixture could allow a home to store a full day’s worth of energy in its foundation, potentially paving the way to an efficient renewable energy storage solution that doesn’t rely on mining rare Earth metals.
Roads made up of the material could even power electric cars wirelessly, the researchers say, or windmills could store their generated energy in their base.
