If you pass superheated steam over solid carbon (e.g. "coke" or charcoal) the water is reduced to hydrogen gas, while oxidizing the carbon to carbon monoxide. This mixture has the nickname of "water gas" and it was once used as a method for producing burnable heating gas, but the process is not particularly efficient and it was probably a bad idea to pipe carbon monoxide into folks' homes anyway. Whatever the dangers of piping in methane instead, at least it's not as deadly toxic as carbon monoxide.
The mixture is lighter than air; both CO and H2 are less dense than molecular oxygen, and carbon monoxide is about par with nitrogen. And it occurs to me that it might be relatively simple to suppress the combustion of this mixture in air with a bit of halon.
Is there any terrifyingly bad steampunk-ish way in which this reaction can be exploited for transportation? The need to have a supply of water on hand to make the water-gas is a bit of a limitation, but still…I think it's possible to imagine filling-stations making water-gas from coke on the spot for pumping into dirigibles. But I was also envisioning the generation of water-gas being used in a submersible vehicle to help maintain buoyancy.

My carbon monoxide alarm was going off, red light flashing on the and green light on the right. It was pointed on very recently that it should have been replaced. What does it mean? Is it still accurate? Thanks in advance 😊

We are headed into the season of the Nobel Prize. Announcements of awards will begin on October 6, with the Physics Prize being announced on the 7th. This year, I decided to have some fun in the “fediverse” and try to tease some nuggets out of the wisdom of the crowd.
While crowds are, in fact, not always wise, it is nonetheless fun to use some of the tools of the open social web to prompt […]

Mice treated with a tweaked version of a bacterial protein rapidly cleared carbon monoxide from their blood, safely eliminating it through urine, researchers report in the Aug. 12 Proceedings of the National Academy of Sciences."

Why a new #zero-carbon #UK #steel plant offers hope and a headache | Steel industry | The Guardian
The problem with making steel using a #BlastFurnace is that it requires very high temperatures and #CokingCoal to #reduce the #Oxygen content as it is made to bond to #Carbon instead. This produces #CarbonMonoxide and then #CarbonDioxide.

PSA: Do you have a carbon monoxide detector in your home? Do you have more than one (think redundancy)? Does it have a fresh battery (or lifetime battery)? Have you tested the alarm function recently?
If you have appliances that may create carbon monoxide, or an attached garage, now is a good time to check all of the above.

How #AirPollution is causing girls to get their first #periods earlier
New research shows that girls in the US are getting their first periods earlier. Exposure to toxic air is partly to blame.
By David Cox, June 4, 2024
"The same trend has also been noted around the world. South Korean scientists have described with some alarm how the number of girls displaying signs of precocious puberty – either breast development or #menstruation before the age of eight - increased 16-fold between 2008 and 2020.
"We're also seeing that these decreasing ages at puberty are even more pronounced in lower socioeconomic status groups, and ethnic minority groups," says Audrey Gaskins, an associate professor at Emory University in Atlanta, the US. "This has important implications for long-term health."
Researchers like Gaskins are primarily concerned that beginning puberty earlier might trigger a cascade of events which have far-reaching consequences later in adulthood. Emerging data suggests that it may not only curtail the fertility window, particularly if these women then enter menopause sooner, but shorten their lives. Precocious puberty has been repeatedly associated with a higher risk of diseases ranging from breast and ovarian cancers, metabolic syndromes such as obesity and type 2 diabetes, and cardiovascular disease."
By David Cox, June 4, 2024
"For several decades, scientists around the world have become increasingly concerned by signs that girls are entering puberty at a much younger age compared with previous generations.
From when girls experience their first period, something which scientists term the age of menarche, to commencing breast development, these seminal changes marking the onset of adolescence appear to be taking place progressively sooner.
"American girls today have been estimated to start menstruation up to four years earlier compared to girls living a century ago. In May, new data showed that while girls born between 1950 and 1969 typically began menstruating at 12.5 years, this decreased to an average of 11.9 years for the generation born in the early 2000s.
