[ RadSafe ] Light Source Lasts 12 Years - No Electricity Needed

[Dan W McCarn]

Just to point out... The tritium is probably part of a high-density polymer
so that it will not become soluble; but I would be quite interested in the
chemistry.  Or is it actually contained as a gas in the microspheres? Can
anyone describe the chemistry a little better than the article?

This could be very valuable, and I wish them the best of luck.  I wonder,
however, what kind of H-3 production facility they will need if their
product really takes off.

  Light Source Lasts 12 Years - No Electricity Needed
   
          A company called MPK is designing a light source that will glow
continuously for more than 12 years without any additional energy.     
The material, dubbed "Litrosphere," can cover a standard sheet of paper for
a cost of about 35 cents, and comes in a variety of colors. It´s also
flexible, and can take the form of either paint or injection-molded plastic.
The material is not affected by the heat or cold, can withstand 5,000
pounds, and stays on constantly. 

According to the company's patent, the material is based on betavoltaics and
uses the radioactive gas tritium as the power source. The beta particles
from the tritium radiation can be safely contained by phosphor-coated
microspheres. Tritium has a half-life of about 12 years. 

MPK specializes in glow-in-the-dark paint and other glow products, although
the new material does not need to be exposed to light in order to work. The
company predicts that the technology could be used for light safety tape,
lighted life rafts/flotation equipment, toys, sports/camping equipment, and
bikes. 

"This has potential to save billions in energy costs world-wide," said Steve
Stark, MPK engineer. "Litroenergy surpasses all known available lighting
options for cost/durability/reliability and safety." 

Litroenergy has recently been added to the New Energy Congress' (NEC) list
of Top 100 Technologies (rank pending). However, its use will likely be
limited to applications that don´t require a great deal of light. 

"The intensity is not very strong," noted NEC member Richard P. George.
"This is good enough for night illumination of rifle scopes, watches, and
emergency signs, but it is not going to come anywhere close to matching the
light output of or replace electric light bulbs (incandescent, fluorescent,
LED, etc.) or kerosene lanterns." 

There are also rumors that MPK may use similar technology as a power source
in the future. 

"It´s not something the company is ready to talk publicly about yet, but
they do have battery technology that would be of the same ilk: betavoltaic
technology allowing continuous power for years in all battery applications,
including automobiles," said NEC member Sterling D. Allan. "They think they
will be able to win the DoD [Department of Defense] contest for the $1
million prize for backpack battery tech."
