Martin,

I have a mercury barometer, mercury in glass thermometers, a coal fire
which I love, a 4x4 which I find useful, a Subaru Impreza turbo as a
toy that drinks fuel at an alarming rate and I use aeroplanes once a
year for a holiday away from the depressing UK climate. No doubt I do
other really environmentally awful things as well. I'm also very happy
which is probably the worst thing of all.

I await a knock at the door.

(When they do arrive I'm ready for them because I do have lots of fuel
saving gimmicks on my central heating system and around the house, keep
fit and slim so as not to trouble the NHS, don't drink too much so as
not to trouble the neighbours and police, help in the community through
Parish Council, School Governor, Village Hall, schoolboy football etc
etc)

Good. Then perhaps Ken you answer a query. I have a modern immersion
heater ( the green type with a jacket integral) where I am and need to
know whether it is cheaper to turn it on for an hour when required or
leave it on all the time. I am out most of the day, most days and so
do not draw much water. Actually, I use it even less now as the stove
has a very efficient back boiler which heats the water up quickly.
My youngest in Windsor asked me the same question the other day.

Regards Robin

Obviously something had to be done about the millions of
workers dying from mercury poisioning in Europe, not to mention the
hordes of innocent users of this utterly lethal substance. They have
also banned lead from solder, I hear. I think it's time we allowed the
EU to wither away, or possibly leave it. Then, though, you find
yourself in bed with the UKIP loonies. Best thing is simply not to
vote in EU elections, which I don't find difficult.

Thats a description of the whole ho****er cylinder rather than just the
immersion heater which screws into the top or perhaps side, BWTH.

where I am and need to know whether it is cheaper to turn it on for an
hour when required or leave it on all the time. I am out most of the
day, most days and so do not draw much water.

The hotter something is the more heat it loses to the enviroment. As you
don't use much hot water I'd say you will be better off heating only when
required rather than maintaining the cyclinder temperature.

In my bachelor days the time switch broke on the CH/HW system, I couldn't
be bothered to replace it straight away and the boiler could heat the
cylinder from cold to hot in about 20mins. So I just used an "on demand"
system, the cylinder was well lagged and would stay useably hot for
washing for the best part of 48hrs. So instead of heating the water twice
a day and not using it, the water was only heated when I wanted it. The
effect on the gas bill was very noticeable, like about a 50% reduction.

Thanks-that is what I thought. I may not need the water, but I sure do
need the stove- which does the water. I just boost the temperature a
bit -like today,after a brutal caving session!!

Dear All
As a dentist who has used mercury in its liquid state for 25yrs
in amalgam fillings and encapsulated mercury everyday for the last 8 .I
would like to give you all my 2 pennyworth for what its worth
There was a repeated warning about mercury contamination in dental surgerys
and possible risk to health 8 years ago ,with Norway I think banning all
amalgam fillings (amalgam is 50% mercury , the rest is silver tin and
copper)
I had the blood level of mercury checked 8 yrs ago, it was about 10 parts
per billion, yes per billion ,how they measured this infinitesimal amount I
dont know.
I had it done again last year and it was the same,bearing in mind I now mix
my amalgam in a plastic fully closed capsule little change.As a dentist I
then place this amalgam in peoples teeth, you would think I would have high
blood levels at least maybe 10 to 20 parts per million,
but the doctor and I were surprised.
Mercury is excreted naturally in the hair and nails and other bits of the
body.
The main scare with mercury came about in Japan in the 50s and 60s where
the population of Minimata injested massive amounts of fish containing
effluent based organo- mercury compounds.The fish also concentrated the
mercury pollution ,and the japanese being big fish eaters started dying of
what is known as Minimata disease ,a brain disorder that leads to confusion
and in extreme cases death.
This is probably why the EEC want to erroneously ban mercury,
This one incident 50 yrs ago.

Do you know the origin of the phrase "Mad as a hatter", thats mercury as
well, though at fairly hefty exposure levels again.

Better tell the BBC. There was a programme last week by a geologist
saying how geology and the industrial revolution had influenced the
colours available to painters and describing the rocks/chemicals used to produce them.
The programme name escapes me.

However, one shot showed the presenter using his bare hands to play with mercury
- swishing it around to see it ripple, break up into 'blobs' and reform again
(just as if it was a bowl of water).

Don't bother warning the presenter - he's probably dead by now from
either the fumes or from the stuff seeing through his pores!

We used to use a sharp pencil to gouge out globules of mercury from the
cracks in the benches in the chemistry lab to see how big a globule we
could make. This was in the early '50s. Fascinating stuff.
