Back in shop class, when I was about, oh, 12, we were doing some metalworks that involved heating things up with a propane torch. Now some kids noticed a thin metal rod will heat up to a glow quite quickly and looks kinda neat if you wave it around fast. The teacher being at his desk at the time (he was a bit of a dick, to be honest), we spent a good while waving glowing hot metal bits around the propane tank.

The valve on the tank must have been faulty, because suddenly the top of the tank was on flames. You wouldn't believe how fast a room full of 12-year-olds evacuates itself when an explosion seems imminent. Some kids went out the door, others went out the window (we were in a basement with a window right at ground level) and some simply hid behind a sturdy desk far away from the flaming tank.

Our teacher wasn't quite disinterested enough not to notice the ruckus and went in to extinguish the fire. First he tried to stamp the flames out with his shoe, managing mainly to re-arrange the patterning of his soles, and then got a fire-extinguishing glove which did the job.

As I said, this teacher was something of an asshole, seeming to get his kicks from berating and belittling the kids he was teaching, but this time what followed was a very sober and concise lesson on fire safety. Everyone was left with the feeling we'd all gotten very lucky, and there was this worldess concensus that it'd really be best for all concerned if no-one said a word about what had happened, ever.

I kept cringing waiting for something bad to happen to the coke can guy. I don't like things under pressure and I refuse to work on even low pressure gas lines at my house. I don't like being near propane or oxygen tanks. Maybe I've played too many video games.

That is a propane filling station or liquefied natural gas. Not regular gasoline or petrol for sure.

@spawnflagger: Less CO emissions than a white gas/fuel stove? I call BS.


Yeah, it doesn't go into detail on the measurements. Probably the claim is that "because it burns more efficiently, our stove needs less wood than these other wood-burning-stoves". But if you compared that to cooking with propane or natural gas, I'm sure the latter 2 will be much better than wood. But their target market is one where these other gasses aren't readily available.

I was looking at Thermoelectric Generators (TEGs) as a result of seeing this video. It's basically a peltier cooler in reverse.

so because of the low melting point, the pewter liquifies when placed in the sand under plywood on the beach?


Looks like he has a little propane camping stove, you can see it very briefly at around 8 seconds.

Electricity? Does that come from propane as well? Where is that fresh water coming from? Did she have to drill a well?

It's just propane in a balloon. Hydrogen will make a bigger bang, but it's harder to get a hold of.
