Sourcing and storing energy is often unsustainable and intermittent—a problem researchers from the International Institute of Applied Systems Analysis in Vienna, Austria seek to solve with the Lift Energy Storage System, which turns skyscrapers into giant gravity batteries. Researchers found that “excess renewable energy can be stored as potential energy by using it to lift something heavy up to a higher point,” according to New Atlas. “That energy can then be released by using gravity to drive some kind of generator.” Thus, existing skyscraper elevators could easily transform into the foundation for regenerative batteries. Not only does this solution operate with around 92% efficiency, it can also store tons of energy remarkably affordably. Read more about the simple science behind this innovative plan at New Atlas.
