I just received a stumbleUpon that I just had to share here. It’s a page about a light source that can last up to 12 years. It’s a light source called called Litroenergy by it’s creators.
It’s supposed to have all kinds of great features, lasts 12 years without any kind of recharge or electricity, doesn’t pollute, can take a severe amount of physical torture, doesn’t emit harmful ultra violet rays and can be made to produce almost any color of light. However before you decide to run out and get involved in this you might want to make sure that your health insurance is full coverage and paid up completely.
You see, there is a fly in the ointment that may well keep it from ever being marketed. According to the patent application for these “Long life self-luminous microspheres”, the secret to how they work is:
self luminosity by means of a plurality of glass or polymer microspheres containing both a light-emitting phosphor and a radioactive gas.
The radioactive gas in question is tritium, a radioactive isotope of hydrogen. Not only am I am not a hamster, I don’t glow in the dark and frankly, I think I’d like to keep it that way.
I think that it’s probably not going to matter that tritium does not emit “hard” radiation. The simple fact that it’s radioactive is going to have people dropping it like a whole truckload of hot potatoes.
