"they don't even bother with (glass) envelopes, but just build the tubes far enough apart and/or pile rocks between them."
#blink# The distance between tubes is so that the emissions from one cathode won't interfere with the neighbouring tubes? (Inverse square law and all that...) I was thinking of doing this someplace with atmosphere, but yeah, that's a cool trick for the moon.

Will do. Thanks for the suggestion.
