Love the entry. I knew bits and pieces of it already, but it's really well put together. Except it doesn't mention how carbon arc lamps worked, am I going to have to look it up. smiley - winkeye

How do carbon arc lamps work? They create a cloud of carbon particles which conducts electricity. They don't need very high voltages. I made one once using a car battery and two dry-cell electrodes which I'd sharpened. Not recommended unless you have welding goggles.

I liked this article too. Technical enough to be truly interesting, with explanationes for therest of us too (I especially like the phrase 'sucking holes')

I'm eagerly wathcing the development of light-emitting-polymers...

Have you got a mobile phone? You can watch the development there.
