This is gold. (Well, no. It's oil.)

There is an awesome book "Reminiscence of a stock operator" by Edwin Lefevre, the story is about one guy and he does that with coffee in the US, not one, but 2 times. The government actually had to come in and take it from him... The book is a mixture of fiction and real life and it's just great! One of my favorites
It is an awesome book and its an extremely thinly disguised biography of Jesse Livermore. Its interesting to read up on why its thinly disguised. Its widely believed the author both got, and planted, stock tips for Livermore, but the author wanted no written legal document connecting them in case things went wrong and he ended up in court discussing his documented long financial relationship w/ Mr Livermore. Legally…
Another notable excerpt from the linked state safety agency document ( http://www.michigan.gov/documents/cis_wsh_cet5041_90142_7.do... ): -- Two employees of a fertilizer company in Riga, Michigan, were assigned to install a new float valve in an old 35-foot deep cistern for a new 300-foot well. This cistern was covered with a concrete slab with entry through a covered manhole. The first worker entered the cistern an…

The friends I play Urb-X with are hyper aware that it's the heavier-than-air gasses that pool and that kill you. I find it amazing and depressing they didn't have any sort of safety gear or air monitoring. In the UK, I'm sure this would have breached both working at height and enclosed spaces working regulations. Even if we're exploring something as pathetic as an old ROC bunker only _one_ of us (usually me) goes dow…
Absolutely. This is also well known in the amateur caving community too, who follow similar practices to those outlined by yourself. I too find this crazy. As they say in the diving industry about water and confined spaces: a deceptively easy way to die.
(irrelevant, but for the record, cave diving scares the pants off've me =) )

I've thought about getting a used H2S detector on eBay, but ideally you'd want to test and calibrate them, and there's the rub.
I've looked into it in the past and keep looking at atleast a £500 cost -usually more if you want O2, CO, CO2, H25 (I think those were the ones I decided I was interested in).... and _then_ there's the certification cost, so I really can't justify it (though I'd love to). My friends dad used to be a safety inspector duwnt' pit in the 70's and he's been trying to convince me to get an old Davy Lamp and to just pay att…

> its a comedy in the sense that market prices currently have no relationship to fundamentals from a Graham perspective You missed the whole point of Security Analysis and Intelligent Investor(another Graham book). The market is irrational from time to time, so you patiently wait on the side when prices are overvalued and invest in fundamentally good companies when prices are undervalued.

The short version is more likely CO2, not CO, and the detector was probably fooled by methane. In more detail: I was motivated to google, and much like radioactivity or electric current its possible to measure "scary" things to low levels that don't usually matter, and according to a 1982 gastroenterology paper that I found, aerobic fecal fermentation will produce an irrelevent yet measurable extremely low CO output…
>"so its unlike bowel gas analysis was a high priority in the specs" Classic :) After digging through ebay and google images for awhile, I finally found one of the two different units that we used: http://www.equipcoservices.com/sales/rae/multirae_plus.html That one actually has, at least what sounds like, a built in aquarium pump that actually draws air into the unit. The other style we used seemed to be completely…

It ends up being the same argument on a high level that for both operational and practical reasons the sensors usually respond to anything that burns / reduces in the presence of oxygen regardless of specific chemistry and design.

Relatedly(?) When I had a diesel car, I bought and stored a small barrel of biodiesel in the basement of our apartment (saving like $0.05 a gallon!). I was told that diesel doesn't burn except under extreme pressure, and that you could throw a match into an open cup of diesel and it would just go out. Never actually tested that out.
You can throw a match into an open cup of cold diesel and it'll go out. But if the cup gets hot, diesel vapour will start coming off the top, which will ignite. If you're unlucky it'll produce enough heat to vapourise more diesel, etc. Also, if you let the cold diesel touch cloth, it'll get wicked up, and the diesel-soaked cloth will ignite really easily. That will in turn generate enough heat to etc. The same applie…
