Town gas was largely hydrogen (with a substantial level of carbon monoxide, which is why it was poisonous) whereas natural gas is largely methane.

However ...
The brain is wonderful at filtering the crappiness, be it sound or the imperfections on a projected wall. After a while, if you are actually listening to the music, most of it doesn't matter in day to day life. People who still hear the reduced quality should either not download pirated music or listen to something that actually absorbs them

So what, without looking it up, it the explosive concentration for mains gas ?
No peeking, if you don't know, take a guess ...

Yes it does. It gives 14.5.

For many years, I've sailed off the west coast, particularly Wales, Scotland and Ireland. More recently, I sailed the south coast extensively and also crossing the Channel.
With our prevailing winds, I was staggered by the number of carnival balloons that end up in the Channel. Made me rethink the kind of activities I organise at charity events as a result, not for turtles in the Channel but other sea life.
Saw a basking shark in the middle of the sea lanes in the Channel a couple of years ago. Draw a line from Weymouth to Guernsey and whether that crossing the lanes is roughly the location.

What is your source for claiming that town gas contains a lot of methane?

CH4 takes 2 02s, air is 1/5 02, so how about 10:1 air:gas?

8% - 18% is the official explosive concentration, so yes, you are within the limits there- Vote on answer

This is why Cambridge was converted quite early too many students with their heads in the gas oven if they couldn't hack the courses;(

I remember seeing it 'live' as a kid. And the spaghetti hung on the trees was so badly done it was obviously a spoof. Despite the film focus being as soft as they dared.

I can see it might be useful if top posting was the norm since his reader would give him the new bits first. But it's not - and only his replies are top posted and presumably he knows what he's written? Just curious...

Hmm. Methane may not be actually poisonous (unlike CO), but it will still asphyxiate. OTOH, I think CO has some anaesthetic effect concentrations, so presumably a potential suicide dies whilst unconscious.
I assume that makes CO preferable if (a) you have the option, and (b) you're trying to end it all. The scrappage scheme will cause problems in that regard though - IIRC some well-tuned engine-cat combinations now emit virtually zero CO (although plenty of CO2, which kills pretty effectively).
Macabre. Thread change?
