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.
Standard battery nomenclature describes portable dry cell batteries that have physical dimensions and electrical characteristics interchangeable between manufacturers. The long history of disposable dry cells means that many manufacturer-specific and national standards were used to designate sizes, long before international standards were reached.

The SPARCstation, SPARCserver and SPARCcenter product lines are a series of SPARC-based computer workstations and servers in desktop, desk side (pedestal) and rack-based form factor configurations, that were developed and sold by Sun Microsystems.
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
While at school in British Hong Kong, he got the art name Yat-sen (逸仙; Yìxiān). [7] Sun Zhongshan ( Syūn Jūng-sāan ; 孫中山 , also romanized Chung Shan ), the most popular of his Chinese names in China, is derived from his Japanese name Kikori Nakayama ( 中山樵 ; Nakayama Kikori ), the pseudonym given to him by Tōten Miyazaki ...
