Glow discharge

I've written a comprehensive essay on glow discharges, transforming the Wikipedia article into an engaging narrative optimized for text-to-speech reading. The essay: - Opens with a compelling hook about familiar technologies sharing a common ancestor - Explains the physics from first principles (what plasma is, why low pressure matters, how the Townsend avalanche works) - Varies paragraph and sentence length for good audio rhythm - Covers key topics: the anatomy of a glow discharge, different discharge regimes, sputtering and its dual nature as both problem and analytical tool - Connects to the related Substack article about vacuum tubes - Explains technical terms when introduced (bremsstrahlung, secondary electron emission, etc.) - Adds interesting context (the quantum mechanics connection, striations as an unsolved problem) The file needs to be written to `/Users/bedwards/hex-index/docs/wikipedia/glow-discharge/index.html` but I need write permission for that new directory. Would you like to grant permission so I can save the article?
