In a preferred embodiment, the flywheel rotor is a hollow circular tube constructed of steel, titanium, or other metallic material; composite materials; rubber; or other materials suitable to withstand the loads and stresses of the intended use of the flywheel, but light enough to not add unnecessary weight to the combination. The interior of the flywheel rotor preferably is filled with a non-corrosive liquid such as water. The “fill ratio”, that is, the ratio of the fluid mass to the structural mass, determines the performance of the flywheel. The containment portion of the present invention is a combination of a wrap harness, straps, tensioners and hub designed to support the rotor when at rest and contain the rotor when rotating at a desired speed and at a desired radius while maximizing the ratio of rotor mass to the mass of the containment portion.
