This chap recons his black water tank will keep the water cooler than a

All depends on the relative external temperature. A black surface will
radiate heat more efficiently than a white one; not so certain what
happens when the container is clear - I guess that's dependent on the
other characteristics of the material.

They certainly *could* be a reason why he's right.

Does it really matter? if its a tank for general purpose water and not for
human consumption as he has stated then the colour is irrelevent.

As to the colour of something that keeps cool...
Manufactureres changed heatsinks from silver(aluminium) to black because it
dissapated heat better.

It will also absorb better on a hot day when you want it cool

The message
from raden contains these words:

I think the heat issue is a red herring but he does have a point. Clear
plastic allows more plant or insect life to flourish in the tank and
that is not exactly desirable even if you are not drinking the water.

Yes, I realise that, but I don't think it's as simple as being a
symmetrical process. It would depend on the difference in temperature in
the heating and cooling phase, the volume of water, and the length of the
phases (at least those, and probably many more variables).

It may just be that the vendor has owned both, and found the water is
generally cooler with the black one. You can't beat empirical evidence :-)

No it's a quiet market town. One of the Welsh Marches.

And there is a place that supplies loads of those things somewhere
nearby. A paint factory I think. £15 is about what it is worth,
considering you will have to get a pick-up or something to fetch it.

I avoided saying such a thing, but yes, you're right

Depends where you're starting from, doesn't it.

When I was in Aberystwyth I'd have *loved* to go to Oswestry.

In my younger days, I had a girlfriend who lived there, well at Knockin
actually, but close enough ...


Actually, a trip to Shrewsbury was a big treat - S'bury had both an
Argos *and* a Tandy.

It now hosts an unbelievably diverse range of names now. I wonder how it
can sustain them

It even had a sex shop, although I was too young to be allowed in.

The one at the bottom of Wyle Kop or the one near castle gates ?

Probably all the people from Aberystwyth shopping there.

I went out with someone from Weston Rhyn once, we were in Oswestry a
lot. It is a dive.

The diverse range of names are also cropping up elsewhere as well so
Shrewsbury will have to do something really special to keep them,
although knowing SABC and their hatred of people and vehicles it won't
be long before everything and everyone is banned from the whole of the
town.

No

Are we talking about the same Oswestry?

Heh, I spent a few weeks there the other year doing a job, I think I
preferred Aber. Mainly because the job and digs were right above a
bakers so it was fresh cream cakes all day and round the corner is a
butchers who does some belting pork or beef balms oozing with apple
sauce\yorkshire puddings\stuffing etc...

But being black it will lessen or even stop algae growing inside, from
my first hand experience from useing both.
