The Lift Energy Storage System (LEST) would make use of the existing elevator systems in tall buildings. Many of these are already designed with regenerative braking systems that can harvest energy as a lift descends, so they can effectively be looked at as pre-installed power generators. The LEST would also make use of vacant spaces throughout the building, ideally close to the top and bottom.
