Hi all
Decades in the future people will be astounded that He was squandered by being used in balloons to entertain childrenIt is an non renewable resource, very much like oil, but for many applications there is no alternative possible. It's used in PC hard drives, super-conducting magnets, essential for ultra low temperature applications around a few Kelvin, scientific research, leak detection for vacuum systems, medical equipment and, perhaps in the future fusion machines.

I wasnt sure what the heck she was talking about. And my dad replied. i dotn see anyone gripping about all those released in the presidential partys. lol Later my explained how birds could choke on the ballons.While it was a valid concern I think it was outweighed.. but what do I know.lol
helium isn't consumed! it is released BACK to the atmosphere where it cam from originally. the only wasteful part about it is that it has to be isolated again to use for something else costing more money.
Our atmosphere has helium in it and we are talking about kids balloons, not many kids I know are in space!
Although helium is the second most abundant element in the universe, most of it in the Earth’s atmosphere bleeds off into space.

I believe there are trace amounts of Helium in the ambient air; in the range of parts per billion/trillion. I also understand that the technology exists to extract it, but not economically. I recall during a chemistry lecture back in the dark ages, our professor told us that the fuel tanks on space vehicles, in order to prevent collapse during the rapid use of fuel, were pressurized by helium. He surmised that the Russians, who had no known helium resources of their own, must have extracted it from the air. True or not, I don't know, but it makes a good story.
Russia is one of the countries that have Helium in their Natural Gas Wells. They are a net exporter of Helium.
