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 weight.
Energy Vault Testing Tower in Castione-Arbedo, January 2022. In 2017, Energy Vault was founded by the startup studio Idealab.

Nickel is the most common contact allergen worldwide (of people with contact dermatitis, 11.4% in Europe, 8.8–25.7% in China, and 17.5% in North America are allergic to nickel). [1] Nickel allergy, and contact allergies more generally, can develop when people are any age, but they are most likely to develop in early adulthood.
For inflammation of the eyes, a common allergy symptom, Dr. Chase’s Old-Time Home Remedies, recommends heating the white of an egg in a tin cup mixed with powdered alum, a substance used ...
These are now a common consumer and industrial type. The battery has a hydrogen-absorbing alloy for the negative electrode instead of cadmium. Lithium-ion battery: The choice in many consumer electronics and have one of the best energy-to-mass ratios and a very slow self-discharge when not in use.
The all new Lucid Gravity SUV is hugely important to the electric vehicle automaker's success, and is slated to enter production at the end of 2024. Prices will start around $80,000.
With millions of abandoned mines worldwide, a new study provides a compelling argument for their inclusion in a green energy future.
Electrogravitics has become popular with UFO, anti-gravity, and government conspiracy theorists [5] where it is seen as an example of something much more exotic than electrokinetics, i.e. that electrogravitics is a true anti-gravity technology that can "create a force that depends upon an object’s mass, even as gravity does".
