A plasma ball with filaments extending between the inner and outer spheres. A plasma ball, plasma globe, or plasma lamp is a clear glass container filled with noble gases, usually a mixture of neon, krypton, and xenon, that has a high-voltage electrode in the center of the container.
William P. Parker is an American artist, scientist, and entrepreneur, best known for inventing the modern design of the plasma globe. [1] The invention occurred in 1971, when Parker was working as a student in a physics laboratory at the Massachusetts Institute of Technology and accidentally filled a test chamber to a greater-than-usual pressure with ionized neon and argon.

The first commercial plasma lamp was an ultraviolet curing lamp with a bulb filled with argon and mercury vapor developed by Fusion UV. That lamp led Fusion Lighting to the development of the sulfur lamp, a bulb filled with argon and sulfur that is bombarded with microwaves through a hollow waveguide. The bulb had to be spun rapidly to prevent ...

This work and later experiments using mammalian cells led to the establishment of a new field of research known as plasma medicine. The dielectric barrier discharge configuration was also used in the design of low temperature plasma jets. These plasma jets are produced by fast propagating guided ionization waves known as plasma bullets. [64]
Original - Short video of a plasma ball/lamp in action Reshot - Short video of a plasma ball/lamp in action Reason Self nom but I feal it is a good video that shows the movement aspect of a plasma ball better than an image could. It is nominated here because featured videos (unlike featured sounds) dosen't appear to have got off the ground.
Kmart's longest lasting logo, used from 1969 to 1990. Under the leadership of executive Harry Cunningham, S.S. Kresge Company opened the first Kmart-named store, at 27,000 square feet (2,500 square meters), which was referred to by Kresge as a "bantam" Kmart and was in fact originally intended to be a Kresge store until late in the planning process, on January 25, 1962, in San Fernando ...
CNC plasma cutting Plasma cutting performed by an industrial robot. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well.
