In all seriousness, I would treat the Reactor with the same caution I would any other stove when using it in my tent’s vestibule by giving it as much ventilation as possible.

Winter stove, reactor?

Given the sort of wind blowing the tent around, I doubt that he was at much risk.
It’s the example he sets in the minds of young watchers. Not good.

What, that it is quite normal to be cooking dinner outside your shelter in a howling storm? And then going to bed with snow on your clothing?
Ah well.

The wind is blowing the CO right into his face, surely you can see that.
I rather thought that the wind was blowing in every direction! :)
If his face is not right next to the stove, the CO level will be diluted by the wind mixing with the relatively small amount of hot exhaust gas. It is when the stove is run in an enclosed space that the CO level in the whole space can rise to dangerous levels.

The Reactor Stove System design features radical, patent-pending technology including a convective and radiant heat burner, and an internal pressure regulator. As Seattle-based production increased and stoves were put through MSR’s stringent testing protocols, the majority of units met demanding test standards; however, a minority fell short of a particular worst-case combustion condition test, and produced higher than desired levels of Carbon Monoxide (CO). Carbon Monoxide is a byproduct of all fuel-burning stoves, and although the elevated levels produced by the Reactor would have posed little appreciable CO risk to those using the stove as directed, MSR nevertheless elected to further hone the Reactor stove design so that it consistently meets the testing standard.
“We’re all very disappointed that we’ve been unable to meet our previous ship date commitment, and are sorry for letting so many down,” said Ken Meidell, Outdoor Group Vice-President of Cascade Designs, parent company of the MSR brand. “But we have always worked by high technical standards and will not compromise on the quality and consistency of our products.”
Production of the Reactor Stove System has resumed, and the validation testing will be repeated. The company is declining to communicate a firm shipping date, and recommends checking the website at msrgear.com for updates.

That video was actually inside his tent:
start watching at 29:18

Indeed! But still a little exposed to the wind!
I notice that around 22 min the tent actually blew away a couple of times while he was trying to pitch it.
A wild trip. I’m too old for that.

Good grief, a lot of hand wringing about tent cooking… been doing it for 45 years in winter weather, no harm, no foul.
An actual tempest in a teapot…
Or maybe a teapot in a tempest?
But no, there was no hand-wringing. I suspect most walkers who go out in bad weather or on long trips get to cook inside at least some of the time. It’s called staying alive.
Cheers
