No - I was just guessing. But as I said, footage of him as a much younger

We'll have to wait for later to discover what he does about fuel for the

They generally towed a trailer of fuel and another shed on wheels as a

Forncett Steam Museum (S. Norfolk), of a steam loco with just such an
arrangement, which called there on its way to some rally in Yorkshire.

Just looked through all the photos I can find, and i dunno where these

Apparently all cancers, because of its influence on 'free radicals'. It's
well documented. Tobacco smoke can have an effect on all cells in our
bodies. That doesn't mean that it does nor that all cancers are caused or
only caused by smoking. I did, carefully, say 'indicated'.

I thought it had a strongly genetic element

Oh indeed it has. Only men get it.

In fact most men get it, only a few die from it but many die WITH it.

The same applies to lots of cancers though. There's a lot of it about :-)

I had once a wonderful buk called 'rallying to Monte Carlo' which
described an jaguar with a special metal cup built into the water
cooling loop. A tin of soup could be placed inside (presumably
pre-perforated) and became heated very quickly. Some time in 1955 I goove.

I had the same thought. Whether the OP means any form of SS generic
'thermos' flask, or specifically those made by Thermos, isn't clear.
There are plenty of adverts out there for SS vacuum flasks. OTOH it
wouldn't surprise me if the cheaper ones are not true vacuum flasks
but are as you describe, with some form of insulation material between
the walls. Having said that, I see the supposedly genuine Thermos
flasks on the John Lewis web site don't describe themselves as vacuum
flasks, although other flasks there, do. http://tinyurl.com/ybqtzf39

I always assumed that the reason hot things cool a little faster in SS
flasks was because SS has a thermal conductivity roughly ten times
that of glass.
https://en.wikipedia.org/wiki/List_o...conductivities and
scroll down a long way.

Yes, presumably when the inside skin heats up, the heat conducts to the neck
of the flask (AIUI, the only part where there is contact between inside and
outside skins).

I can never look at one of the modern wide-necked stainless steel flasks
nowadays without remembering a woman that I used to work with. She was one
of a group of us who went to lunch each day in the work canteen. One
lunchtime, when she was about half-way through her lunch, she pulled a large
flask out of her bag and proceeded to tip the uneaten dinner into the
flask - a sort of vacuum flask doggy-bag. One of my colleagues gave her a
look with spoke volumes - "WTF are you doing" - because she put her pud in
with her main course :-(

She explained that she sometimes got hungry in the middle of the afternoon
and her blood sugar got low, so she saved some of her lunch to eat later on.
Excellent idea, but the idea of mixing her pud in with her roast beef and
potatoes was very weird. Prior to this, she'd intrigued some of us by eating
her pud *before* her main course - and my wife and I still use her name
("let's have a Jane-snack") to describe having a dessert (eg some biscuits
or a cake) before the savoury part (sandwiches etc) when we're having a
picnic.

It was a reply to a long thread in March 2005 from someone who patently
disagrees with those who find stainless steel flasks perfectly serviceable.

I think they are fine. And, as with all flasks, extended life can be
achieved with a few offcuts of insulating foam board, a sleeping bag, a
duvet, etc etc

They're both vacuum, but it's possible that the steel ones don't keep the
contents hot for as long as the glass ones because the neck connection
between the inner and outer is thermally conductive steel rather than
insulating glass.

Couldn't they use a non-conducting (plastic) ring to join the inner and
outer skins, or would there be problems keeping this air-tight to maintain
the vacuum?

Alternatively, I wonder why there aren't vacuum flasks which are all-plastic
(eliminating the need for a plastic-steel joint at the neck).

When I've broken a flask I've never seen a steel neck connector left

Is there a plastic at a reasonable price with the rigidity necessary to

PS

When I buy a Thermos with the space in the stopper for sugar etc I cut a
piece of Kingspan etc to be a tight friction fit it. I've not measured
the effect on heat loss but it certainly stops the top of the stopper
getting so warm.

More that glass is cheaper and the manufacturer doesn’t
care if you break it, they get to flog you another one.
