Comments on GlowRing: Light Without Power
The GlowRing will glow for up to ten years in funky colors. GlowRings do not require any external power source (and no internal source - a battery - either!) (Read the complete story)

"In James Blish's SPOCK MUST DIE, shuttlecraft are equipped with "glow-pups". These are set in the ceiling, and provide light when there is no power. They are filled with "ethon" gas, which glows due to being excited by a tiny radioactive source."

"Yes, quite cool, but I'm having trouble finding someone in the US that sells them."

"You won't find anyone in the US - dispite safety, the tritium ("special gas") makes it illegal."

"These are tiny versions of tritium safety lights, eg. those powerless "EXIT" signs. The vendor won't ship them out of UK because of tritium-related regulations (despite the very tiny amount present in the device), but maybe you could get somebody who can buy it for you and then send it by normal person-to-person post and hope nobody will notice and seize it. It works for overseas pharmacies."

"And the Brits wonder why thier teeth are falling out of their heads. ;-)"

"Are these available in Canada?"
( 12/28/2004 8:26:40 AM)
"You can get them in the US through the carribean on eBay. Warning though...the first time I dropped mine, the glass tube inside broke, and within a day it was totally dead. These things have absolutely no shock protection, and keyrings do frequently get dropped."
