These line-conditioners actually perform well given the cost, but never buy used surge-arresters given the finite spike hit-count. Best of luck =3
Some fabs are starting to reuse helium in downstream processes but there’s only so much they can do without expanding their core competency into yet another complex chemical manufacturing process.
MRI machines don’t need high purity helium and the contamination doesn’t “gunk up” all the tools so it’s not an issue to recycle it there.
They have a patch strategy! They considered requirements when deciding the strategy! They have a documented strategy, it’s just very brief. (“Don’t.”)
The Trump admin may have similarly thought about this issue for a few seconds, shrugged their shoulders and decided that this might force manufacturers to go on-shore.
You and I know it won’t, certainly not in the immediate future, which means massive disruption to industry, but that’s not the same as “no plan”.
Grade 6 (6.0 helium = 99.9999% purity) The closest to 100% pure helium, 6.0 helium is used in the manufacturing of semiconductor chips – Grade 5.5 (5.5 helium = (99.9995% purity) Like 6.0 helium, 5.5 ultra pure helium gas is typically considered “research grade,” also used in chromatography and semiconductor processing
Grade 5 (5.0 helium = 99.999% purity) This high purity grade helium is also widely used for gas chromatography, mass spectrometry, and specific laboratory research when higher purity gases are not necessary, as well as for weather balloons and blimps.
Grade 4.8 (4.8 helium = 99.998% purity) The highest of the “industrial grade” heliums, 4.8 grade helium is often used by the military. The rest is classified...
Grade 4.7 (4.7 helium = 99.997% purity) A “Grade-A” industrial helium, 99.997% helium is mostly used in cryogenic applications and for pressurizing and purging
Grade 4.6 (4.6 helium = 99.996% purity) Grade 4.6 industrial helium is used for weather balloons, blimps, in leak detection
Grade 4.5 (4.5 helium = 99.995% purity) Often the grade most commonly referred to when people say “industrial grade,” 99.995% helium is most commonly used in the balloon industry
Grade 4 (4.0 helium and lower = 99.99% purity) Any helium that is 99.99% and down into the high 80 percents is within the range of purities referred to collectively as “balloon grade helium.”
Turns out that you are right, some balloon gas is 80%. Specifically, the "Balloon Time" tanks you can buy at places like Target say "not less than 80%" helium.
On the other hand, I went to AirGas and a few other suppliers and they seemed to have 95%-97.0% helium gas as their definition for balloon grade.
You have the entire collected knowledge of mankind at your fingertips. You could do 30 seconds of research and find an answer better than "I don't think that sounds right".
So could you, right?
One’d think that they’d keep more than a couple of weeks’s supply of critical materials —to bad many copied Cook’s and others’s JIT inventory management for everything.
More than just from inflation? (sorry, not sorry!)
In the 1980s, I assume getting rid of the "strategic reserve" of anything would have met more pushback, because of primal fear overriding greed.

Kidding aside, the US has had libertarian pipe dreams for the better part of its history. The aberration was the New Deal period up until the mid 60s.
Sounds like Obama kept the gas taps flowing, instead of locking it up because authorization to sell it had expired. Here is the whole record: https://www.congress.gov/bill/113th-congress/house-bill/527/...

There are billions of people in the world, and you are one, and you have your one set of opinions out of billions.
Nobody endowed you or your opinions with any sort of infallibility or superiority over others.

But yeah, that would make more sense.
This whole administration is such a fiasco.
And I say that with his permission, since he’s on camera asking to be called out if he did exactly what they did with the Supreme Court not four years later.
