I was going to bump a thread that I killed sometime ago. Turns out... most the threads I killed ended up being my own. So I figured... what's the point of bumping one of my own threads when I could just start a whole new one that'll end up going nowhere?
 
if today is your birthday it looks as though you have the courage to be yourself and see your projects and ideas brought to compleation. You are strong and seldome... if ever afraid of opposition or fighting for your way of life, however; you do not seek out confrontation.

Happy Birthday.

yeah... happy birthday April 10th people!!!

now all you have to do is work on being a bit more stable, less obsessive, and learn to relax more often. Let shit slide down hill... it's where it wants to go after all.
 
if tomorrow is your birthday... you don't really have an overwhelming need to be a star. When you are at the center of attention it is more often because of your usefulness rather than your ambition. You all enjoy being part of a decision making team that you are often the leader of.
 
Well you're not exactly giving us much to work with, ya know...

just so you know... it still feels good.



Where does Helium come from? or rather... how is it collected?

Where does Helium come from? or rather... how is it collected?

Helium in the crust is produced by the radioactive decay of uranium and thorium which are present in varying concentrations throughout the crust, but helium migrates and can collect in certain areas when conditions are right. Thus the greatest concentrations (trace amounts up to 7% by volume) of helium on the planet are in natural gas fields, from which most commercial helium is derived. As of 2002, over 100 million m³ (3.5 billion ft³) were produced annually with 80% of production from the United States, 16% from Algeria, and most of the rest from Russia. The principal source for U.S. production is the natural gas wells of the U.S. states of Texas, Oklahoma, Arizona and Kansas. Helium is also produced in Canada, Poland, the People's Republic of China, and Qatar.

Since helium has a lower boiling point than any other element, low temperature and high pressure are used to liquefy nearly all the other gases (mostly nitrogen and hydrocarbons such as methane) from natural gas in order to extract gaseous helium (the general process is called fractional distillation). The resulting crude helium gas is subjected to a process of purification in which almost all of the remaining nitrogen and other gases are precipitated out of the mixture through successive exposures to lowering temperatures. Activated charcoal is used as a final purification step, usually resulting in 99.995% pure Grade A helium. The principal impurity in Grade A helium is neon.

Diffusion of crude natural gas through special semi-permeable membranes and other barriers is another method to recover and/or purify helium. Helium can also be synthesized by bombardment of lithium-6 or boron with high-velocity neutrons in a nuclear reactor to produce He-4 and tritium. The tritium decays with a half life of 12.5 years to produce He-3. This method of production, however, is not economically viable—at least for making normal commercial-grade helium. Fusion in exploding hydrogen bombs creates helium as well.
