A gravity battery is a type ofdevice that stores —theE given to an object with a mass m when it is raised against the force of (g, 9.8 m/s²) into a height difference h.In a common application, whensources such asandprovide more energy than is immediately required, the excess energy is used to move a mass upward agains. Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy.

Energy storage Flywheel Renewable energy Battery Magnetic bearing A B S T R A C T Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently.
The kinetic energy of a high-speed flywheel takes advantage of the physics involved resulting in exponential amounts of stored energy for increases in the flywheel rotational speed. Kinetic energy is the energy of motion as quantified by the amount of work an object can do as a result of its motion, expressed by the formula: Kinetic Energy = 1
Other electricity storage technologies involving weights include those being developed by Gravitricity, Gravity Power (shown below), and Ground-Breaking Energy Storage (effectively cutting a large cylinder of earth and then raising it by pumping water underneath). We can also use buoyancy as a means of storing energy.
Pendulum clock driven by three weights as "gravity battery". An old and simple application is the pendulum clock driven by a weight, which at 1 kg and 1 m travel can store nearly 10 Newton-meter [Nm], Joule [J] or Watt-second [Ws], thus 1/3600 of a Watt-hour [Wh], while a typical Lithium-ion battery 18650 cell [2] can hold about 7 Wh, thus 2500 times more at 1/20 of the
Example (PageIndex{1}): Kinetic Energy of an Object. What is the kinetic energy of an 80-kg athlete, running at 10 m/s? The Chicxulub crater in Yucatan, one of the largest existing impact craters on Earth, is thought to have been created by an asteroid, traveling at 22 km/s and releasing 4.2 x 10 23 J of kinetic energy upon impact. What was its mass?

Thus, your question is void, there is no reason we don''t, because we do. Indeed pumped storage, ARES, and Gravity Light are all examples of using weights to store energy but, like an earlier post suggested, the mass / vertical height required (and resulting cost) makes many examples prohibitively expensive.
