Halo-gravity traction (HGT) is a type of traction device utilized to treat spinal deformities such as scoliosis, [1] [2] congenital spine deformities, cervical instability, basilar invagination, and kyphosis. [3] It is used prior to surgical treatment to reduce the difficulty of the following surgery and the need for a more dangerous surgery.
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.
The first time anyone tries inversion therapy with gravity, they should be sure to have someone standing by, in case assistance is required to get out of the apparatus, or if health problems are experienced. [1] During an episode of acid reflux, small amounts of stomach acid may manage to escape from the stomach and into the oesophagus.
This article needs to show the facts, the uselessness of small scale "Gravity battery" compared to LiIon batteries. I have added simple calculation examples, from pendulum clock to person climbing stairs and King Kong in NYC, neither can match a simple battery. A bus load of scrap in a mine shaft is nearly as expensive as a matching battery.
Estimates suggest abandoned mine shafts could store enough electricity to power the planet
Energy Vault Testing Tower in Castione-Arbedo, January 2022. In 2017, Energy Vault was founded by the startup studio Idealab. [3]In 2019, Energy Vault secured funding from Cemex [3] before going on to secure $110m of Series B funding to become the first energy storage investment of the SoftBank Vision Fund, [4] [5] and won Fast Company's World Changing Idea Award for transformative utility ...
