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.

In the past, the life of the plasma lamps was limited by the magnetron used to generate the microwaves. Solid-state RF chips can be used and give long lives. However, using solid-state chips to generate RF is currently an order of magnitude more expensive than using a magnetron and so only appropriate for high-value lighting niches.

[1] [2] His invention of the Groundstar style of Plasma globe was commercialized and marketed to collectors and science museums in the 1970s and 1980s. His techno-art was marketed through major retail catalog chains & stores such as The Sharper Image. In 2001 he became chief executive officer of EFX, an art and technology corporation ...
Impermeable plasma is a type of thermal plasma which acts like an impermeable solid with respect to gas or cold plasma and can be physically pushed. Interaction of cold gas and thermal plasma was briefly studied by a group led by Hannes Alfvén in 1960s and 1970s for its possible applications in insulation of fusion plasma from the reactor ...
