摘要

The energy store has a flywheel with an electric motor or generator device for driving flywheel by means of electricity and for the transformation of rotation energy into electricity. The flywheel has a flotation chamber (6) with a rotationally symmetric exterior surface, which swivels around its rotational axis (4) surrounded by water (22).
