Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

glow in the dark rimz



http://www.treehugger.com/files/2007...t_glows.php?q=

Litroenergy is a new type of material that emits light for 12 years without needing electricity or sun exposure. The self-luminous micro-particles are called Litrospheres and are said to be non-toxic and inexpensive. The light is said to be equivalent to a 20 watt incandescent bulb (lumens please?).

The litrospheres give off a continuous illumination, and can be designed to glow in any color. They can be injection molded or added to paint. The company that invented the material, MPK Co., predicts that first applications of Litroenergy will be in safety equipment such as safety tape and life rafts. Currently, the cost to light up a 8 ½ x 11 piece of plastic 1/8” thick is about .35 cents. Note: The press release says .35 cents but I think the figure is actually 35 cents.

sick gnar. I want my bike to be radioactive. maybe instead of using depleted uranium in Iraq we could start making bike parts of it.. oh my handlebars are so warm

Depleted uranium, as the name suggests, is non-radioactive. Well, not more than, say, lead.

interesting comment i found regarding this paint


Probably Tritium; Not New; Not Dangerous; Not T100

On Dec. 10, 2007, New Energy Congress member, Richard P. George, Ph.D. wrote:

My best guess is that they are using tritium. Tritium is a radioactive isotope of hydrogen. It is an odorless, tasteless, colorless gas that reacts with the human body in the same manner as natural hydrogen. Beta rays from the tritium hit phosphors to create the glow you see. Tritium has a half-life of 12.5 years, which means that in that time the lamp will be half as bright as it originally was. Trijicon uses tritium in their ACOG rifle scopes in common use in Iraq and Afghanistan by the special forces (government issued) and thousands of individual soldiers who purchased their own scopes. Tritium is also used in some watches.

Beta particle radiation can cause skin burns and are most harmful when they enter the body (becoming small radioactive cancer causing bombs). They can be blocked by thin sheets of metal or plastic. Small amounts of tritium (e.g. one ACOG scope or one watch) have minimal radiation. You would have to have ~10,000 ACOG scopes or ~2,500 tritium watches break in one room to have any significant radiation or risk. I don't know about these paints but I suspect it would be hard for the tritium beta particles to escape the paint such that they could do harm.

The intensity is not very strong. 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, flourescent, LED, etc.) or kerosene lanterns.

Tritium illumination has been around for at least 25 years. This is not a top 100 technology.

Wasn't there a guy on here that actually worked for that MPK company? I remember it from another thread discussing a similar topic.

Incorrect. Depleted just means that it's useless in regular nuclear energy processes. It actually gives off about 60% of the radiation as natural uranium with all of it's isotopes. It's still a highly controversial material. Do you believe everything your government tells you? sounds like you do. Do you have a nuclear physics degree? If you do i'll shut up, but with my degree I'm pretty well versed in the subject. thanks but no thanks.

i feel sorry for the guy with the tritium/brain tumor helmet. that looks like enough tritium the make 10,000 watches or scopes.

As a chemistry major, it's probably not great to be bombarded by beta rays for years straight, but people need not be so afraid of radiation! Of course these would be bad if they were decaying with gamma rays, but it's really not a huge deal--its not concentrated enough to burn skin, and since it's not getting inside your body, it's not doing any internal harm.

Now, back to fearmongering and lead paint.

Laek House has been teaming up with velocity to make some rims coated in his retroreflective stuff, ELVS. cool looking. added to Laek House's line of hats, t shirts, and sweatshirts.

sucks that you can't keep the bike inside at night without putting a dark sheet over it to keep the glow down.

that being said, I want a 100% glowing bike real bad......

the South Koreans just cloned glow-in-the-dark cats... apparently an unforseen side effect... suuuuuuure... let's just hope north korea doesn't get their hands on this glowkitty technology or it's all over.

TRON!!!!!!!!!!!!!!!

in all seriousness, just because it emits radiation doesnt mean its gonna kill you. we are probably exposed to more radiation just sitting in our rooms than that paint gives off

It uses tiny balls of tritium (gas??) and phospho(sp) reactive powder. these balls hold back the low energy beta radiation. but if these nano balls broke, and you inhaled the tritium... not good...
