   There are too many producers...OPEC only produces 30% of the global oil supply. The USA has proven that it can ramp up to meet large shortage in global supply very rapidly with fracking. And there are _thousands_ of oil companies in the USA

   Partially. The USA offers some of the best technology for extracting and refining oil, but no US citizens or companies can offer their expertise to Iran. However, most oil companies are international and have headquarters in multiple countr

   Indeed: https://commons.wikimedia.org/wiki/File:Islamic_Republic_of_... (edited to 2017) 79% of their exports is unrefined crude oil. While exports are not always the whole story, in this case it is extremely relevant.

   Iran's oil is not expensive to extract. These aren't marginal break-even prices on each barrel of oil...rather they're how much their current oil production would have to be sold for in order to balance their national budget,

    My understanding is that he may not have a choice. With a combination of an NSL and the all-writs-act, the US government can likely compel any non-FAANG domestic entity to do nearly anything short of murder.

    I do largely agree with this, but this is slightly outside of the typical use case for these masks. I'm not an industrial hygienist or other true PPE specialist, but I am a chemical engineer who has decent experience with a wide variet

    I figure that a 90-day (or so?) supply would buy us the time needed to build additional production facilities to bring us up to the necessary continuous supply. Taiwan had a huge stockpile, and that let them increase their production from 1

    The elastomeric masks allow any filter to be used in them. I have N95 pads in mine. Once a week I swap in "OV" (Organic Vapor) cartridges before I go change the cat litter, the activated carbon in the OV cartridges filter out harm

    Maintaining emergency stockpiles is the only solution to these episodes of commodity shortages, whether they're caused by increased demand or interrupted supply. During normal times, the US may use several million masks per week. Durin

    I'd assume it would degrade N95 masks. Ozone reacts at least somewhat with both polyethylene and polypropylene at relatively low temperatures and short timelines. This paper shows effects at 95F and 15-90 minute exposures: https:&#x2F
