At the most basic level we're talking about a very public service that has been around for a long time that is a potential weakness/ enormous target for the best funded and most technically proficient intelligence agencies in the world.

That was a theory around why certain countries have fared relatively well, places like Cambodia and Vietnam.

Their populations could have been exposed to similar viruses and would have had some built in immunity.

Hydrogen would be a viable alternate use for the pipelines in the long term. There are some promising projects going on in Alberta for producing hydrogen in less carbon intensive ways.

Hydrogen is even smaller than helium, which is used for leak testing vacuum systems.

I hypothesize that a hydrogen leak is less destructive than an oil leak, but that's still a problem.

Making a pipe leak tight to hydrogen versus leak tight to oil is not even playing in the same ballpark. Hydrogen leaks through practically everything, oil is viscous.

Plus hydrogen burns much more easily and the flame is transparent.

Atomic radius of helium is smaller than hydrogen 31 vs 53 pm. Hydrogen gas is also typically in the form H2, which is much larger. At the same time ofc oil pipelines will still be too leaky.

Favoring a shotgun approach towards GHG emissions downstream is there a better approach towards building an infrastructure distributing hydrogen?

That question isn't intended as rhetorical

It seems it's hard to transport pressurized hydrogen in pipelines as hydrogen embrittles steel. Gas utilities are trying to implement this to lower the carbon footprint of their gas (when hydrogen comes from renewable sources).

The kickback scenario came to mind for me as well. It could even be something less nefarious than a formalized system on a corporate level.

Personal relationships with key decision makers, vegas trips, the old boys club etc. Two companies with that kind of old relationship.

I believe that is what the British are doing.

Nah, the British are just delaying the doses, without any kind of trial in play (other than population-level observation).

There has been a study now, it's just not gone through peer review yet.

Additionally the advice to delay the second dose is now also part of the WHO recommendations.

Note that this is the AZ vaccine. They're also stretching second doses of the Moderna vaccine, which is what we were talking about trialing here.

Now that I could dig

IntelliJ does this! Very convenient for recognizing accidentally hitting it.

I think a lot of the issues with Amazon.ca stem from NAFTA's exclusion of ecommerce. That's one thing I'm actually pretty excited for in terms of the NAFTA negotiations.
