Rob,
Yes, helium could be used for generator cooling, as a stirling engine working fluid, or in dirigibles. However, hydrogen has about half the molecular weight, so it is twice as "good" as a coolant. Half the windage loss in the generator. On the other hand it is only a little bit better than helium in a dirigible. Helium is twice as heavy as hydrogen, but hydrogen is only a little bit lighter than helium :-). Air has a molecular weight of 30, helium 4 and hydrogen 2. So the buoyancy(the difference between air and the gas in the balloon) of helium is 26 and that of hydrogen is 28. I read that Germany wanted to buy helium from us, but since we were mad at them we wouldn't sell it; that forced them to use hydrogen. Wouldn't have helped the Hindenberg as it would have burned anyway, but there would have been fewer people on board - or maybe no piano. As I understand it, most of the world's helium still comes from the U.S.
Gary
from Rob:
Gary,
Any idea why Helium wasn't used?
Regards,
Rob M.

At one time, the only producing Helium gas well was the one in Moab, Utah.
Clear out in the middle of nowhere. The rest of the helium is separated out
of air by air reduction companies, a much more expensive process.

The greatest US reserves of helium are in the natural gas fields
of SW Kansas and the panhandle areas of Oklahoma and Texas.
Amarillo, TX has a large complex where a pipeline originating at
Bushton, Kansas to transport "less than pure" helium for further
refinement and purification.
You can see the facility about a mile or so south of I-40 on the
west side of Amarillo. I think there may even be a "Helium Road"
exit. With a son who has been stationed in Albuquerque several
times during his 20 year USAF career and retired there, we make
several trips a year to see him, his wife, and three grandkids!

I seem to remember that years ago, the helium reserve facility was being touted as a waste of government funds. I don't remember the Senator's name, but it made his list of government waste. Is there a commercial use of helium other than inflating balloons?
They are waiting for the return of airships?
No political views inferred, but I do wonder what they do with this supply?

"They" fill party balloons, breathe the helium, talk, sound funny and laugh!

George,
There are two immediate uses I know of, one is in the mix known as "Form Gas" and the other is a welding process called Heliarc.
Form gas is used in processing metals at high temperatures and for creating the conductor penetrations of glass envelopes. This is still required for some products even though electron tubes (aka fire bottles) are long out of favor. It is a mix of He with 5~10% H2 to reduce the metal surface. We used it to make tubes for HeNe lasers (also out of fashion).
Heliarc is actually at trade name for a family of TIG welding processes. Even with argon as a cover gas, the lower ionization potential of helium still makes it preferred for some types of high purity welding.
I, for one, cannot fathom why the government would retain a "strategic supply" of helium for lighter that air ships when there seems to be an unending supply of very hot air along the Potomac. And, we already pay dearly to maintain that.

While there are even more applications, It is used in almost all the different steps of semiconductor manufacture.
No "He", no micro-chips.
It is also used to find very small leaks in vacuum systems. (The smaller molecule will slip through cracks easier.)
Where I work, they haul helium in by the semi-tanker load.

Matt
I worked at several locations in the company I was employed, and each location had a never ending supply of superheated HOT AIR that explosively released itself on a daily basis. Hot air was in PEAK supply....

That mission goes 'way back. In the '60's we took satellite recovery
JC-130's from Hawaii to Alaska periodically to recover the instrumentation
packages dropped from the balloons above 115,000 ft. MSL. Not from quite
as high as the satellites which were our primary mission, but the Atomic
Energy Commission seemed to appreciate the help. :-)

A friend of mine, Ruckster, used to do this stuff. She was based in Palestine TX and was the ballon electronics tech. They flew them from the SW, mostly NM, from Alaska, and from Antarctica.
I asked her if she remembered Hal. She did not but said "We flew out of Ft. Sumner, NM; Clovis Air force base is 60 miles away. We always called them for clearance, reports, etc; on the way up , and on the way down. And the big balloons: 8,000 lb payload, 1200 ft long, 400 foot around, 39 million cubic feet of helium!!"
A bit of non GMC content and also off topic but here goes: I have a "rule" that I only have Harley T-shirts for places, events or dealers I was at ON MY HARLEY. I have made an exception for two she got for me. One is a picture of an old Harley on the back with the phrase "Glide On Ice" on the front in the Harley shield is written "McMurdo Antarctic Station". The other is a shirt from the Christ-Church NZ Harley dealer.
