I bought one before there was VAT. I got a big one because it was
cheaper than a small one due to Purchase Tax on small ones. Mine was 16
cubit feet. It cost £82.
All its life it had a peculiarity in that the yellow neon would only
glow when illuminated by the room light. I never understood this.
When I decided to replace the freezer I found that it had leaked
underneath. The concrete floor was frozen sold due to water getting
between the cracks and freezing. When we lifted the freezer the floor
came with it.
I now have two Beko uprights. They are fine. As a precaution I gave them
their own mains supplies and their own RCDs, nothing to do with the
house. I also bought two of those little thermometers on a wire. They
cost £12 + VAT. I extended the wires. They give an interesting insight
into the way the inside temp of a freezer cycles up and down.

How much range of temperature does the thermostat allow (its hysteresis)
between switching the pump on and off? I've always wondered.
When we changed our central heating thermostat from an old-fashioned
bimetallic strip to a Hive system, it was interesting to see how much
more constant the room temperature was, as recorded by the internal
temperature sensor of our weather station, than it had been with the
I imagine the same will be true with old freezers (bimetallic) versus
new ones (solid-state temperature sensor).
You were lucky that you replaced your old freezer with a Beko. I presume
from your description of a concrete floor that it's outside or otherwise
unheated. Beko are one of the few manufacturers that still can be sited
in a room that is not maintained at around 15-20 deg C; most of them
stop working if the ambient temp drops below about 10 deg C. I've always
thought that there is something slightly illogical about a device that
is designed to cool the inside of it not working if the outside temp
gets too cold (ie when the pump has to do *less* work). But it's all to
do with refrigerant used, and whether (for a combined fridge/freezer, if
it uses one thermostat to control both compartments, instead of having
two separate ones as they should do (trying to infer the temp of the
freezer from the temp of the fridge is naive in the extreme).
Shouldn't they all be using Peltier blocks by now? I can't understand why we still use the compressor in the 21st century. My car fridge operates at any temperature, it simply creates a temperature difference between the inside and the outside of the container.
And the chief point of studying engineering as a university degree
subject is to understand what products can NEVER be available and stop
wasting time developing them.
Back in my time at GEC elliotts I was tasked with making a pulse
amplifier for a laser rangefinder. The idea was simple., A ruby laser
(might have been CO2: I forget) would fire a pulse of light at the
target, you get a red flash back, measure the time diifference and
bingo. Thats the range for your tank guns to elevate to.
My first project ever and I got some assistance, but got my bit working
and then we took the thing up to the roof to mesasure ranges of some
It was dire. On a clear day we could relaibly detect a white painted
house at 1.5 miles.
For anything tank colored in bad weather - well you might have been
better off with opticval rangefinders.
I was disappointed. Maybe my amp wasnt low noise enough, but I dndt know
how to impriove it so that project got shelved for nme....until a
'boffin' came around. To see if hois elevated knowledge could help
wiotyh aqny issue. We brought up te rangefinder.
"Ah. Um. What is te laser power? I see, and what is the noise figure of
te photodetctor? Ah. I see. I'll get back to you after lunch when I
have done some calculations"....
"Well by my calculatins assuing mo loss in diry air and a good
reflective target like a white wall, you might if you are lucky get
abouut 1.5 miles. Any worse atmospherics or a less reflective target and
itr would be a lot less"
"Anything we can do anbout that"?
"Bigger laser, or a better photodetector, but the detector is near the
limit anyuway, so not much to be gained there".
I do not recall how many more millions of budget were siphoned from that
project into ones with more promise before we told the MOD it was
essentially still born.
No amount of tinkering could overcome the basic physics.
I had a similar problem with Sinclair, but this time I was more clued up
into matters engineering. I wrote several pages detailing why the piece
of ferrite he wanted to use could never power the CRT tubes he wanted to
use in the microvision. (Essentually a poiecve of ferrite can only stire
so much energy, and this energy, times the frequency its driven at, is
the most power you can get through it as a transformer. Frequency was
fixed and synched to linescan, so that was that). I thoiugt Clive
woiukld be delighted to know the thing ciuld nevcer works and stop
wasting tine =me on it. Sadly I was not really aware of the marketing
issues, that he had taken hundreds of thousnans of pounds in advanced
orders and would be in deep water - possibly on criminal charges - if te
fact that hs product not only didnt work, but couldn't work, was ever
revealed.I got 'constructively dismissed'
Its all the same with electric cars and windmills and solar panels
today, They can be proved to be ineffective and not worth the money, but
the people who throw taxpayer money at them don't know that, and the
punters are queing up to advance book their '21st ecntury pocket
televisions' - their electric cars and what have you.
Since its you Bill, reflect on the realities of a pocket TV in te days
- We only had CRTs as a display device.
- to get a decent picture most people required a roof or loft mounted
yagi . A whip antenna on a pocket TV was never going to do the job
(early show prototypes were in fact shown with a secret antenna on the
roof of the dsho hall, and a booster hidden under the stand, to make the
signal strength really high.
- we did just about have some custom Ics designed that half worked.
Today, witha 4G cellular network, 16nm silicon fab and LCD screens, the
thing can be done. Every smart phone shows that. And Clive always knew
what the sheeple WANTED. Just not how to deliver it. Which is much harder.
Nothing has changed. Men with plenty of self assurance born out of total
ignorance assure punters that, given enough of their money, something
really marvellous can be delivered. The reality is that in most cases it
can't. Its just a scam to get money.
Electric cars were where pocket TVS were in 1973. Or computers in 1965.
You could see they would be popular but the technology to make them
didn't exist for any but a few expensive niche applications.
LCDs stared to appear IIRC in the mid 1970s, but it wasnt till around
2000 that they started to be good enough for monitor and TV purposes.
That is an example of a technology that was possible, but required huge
amounts of development to get it to where it was the de facto display
Electric cars? well everything is there except the power source.
Batteries, as we currently understand them, can never be good enough.
The physics says no.
So throwing money at battery research will simply take BEVs to a
slightly wider niche market than the shoolrun/supermarket run.
And its doubtful that without subsidy they will ever be cost competitive.
That MIGHT all change if some other way of storing electricity than
electrochemical or hydrocarbon fuel that is practical inexpensive and
safe turns up.
But there's no point in throwing money at it because we dont even know
where to look. Unless you are a con artist.
When lasers first were invented no one had a use for them beyond light
shows at pop concerts.
We had a solution, but to what problem? They came out of entirely
One of te easire ways to become famous is to assure people that you are
a visionary, can see the future, but you just need a lot of their money

Look at that cunt Geldof. Arguably his 'Aid' has made things infinitely
worse for sub saharan africa. But he's made a career out of it and it's
financed his coke habit.
And he got a knighthood. And he's fucking IRISH FFS!
Jimmy Savile got a knighthood for HIS work bonking underage girls and
possibly boys 'I do so love children'
"As a nation at that time we held Savile in our affection as a somewhat
eccentric national treasure with a strong commitment to charitable
causes. Today's reports show that in reality he was a sickening and
prolific sexual abuser who repeatedly exploited the trust of a nation
for his own vile purposes"
What am I saying?
That the world is very very corrupt, and greed for fame and fortune
driuves many to be compulsive liars, self publicists and that the best
way of covering up their seediness is to engage in 'charitable works' -
its like buying an indulgence to get your sins forgiven

Sciuence as students of Popper understanbd (but wilkinosn pork sword
dpoes not) is not about wehat yiyu can do, its about waht you cant. All
te 'proof'; is not that scuence is right, but that its wrong, and if you
cant priocve it's wrong and it seems to work, its science.
So science is really good at showing what will not work. It's less
helpful at making stuff that should work actually work. Engineering is
always about 'lets think of an idea, eithertest it by building it to see
if it DOES work, or run the numbers on it to see if it DOES work.
90% of tech startups fail because the idea was crap. I suspoect teh
nunber of government funded ones is even higher.
The 'if we throw money at scientists and technologists who promise us
results, they will deliever them' school of thinking is just another
example of leftism - its magic thinking that doesnt represent reality,
just aspirations, and moral self righteousness.
"And if the blind lead the blind, both shall fall into the ditch".
Much of it is quite sensible, but brilliant is overstating it. For
instance, with electric cars everyone but the rich will just have to put
up with 100miles maximum range, our rulers will not mind that too much.
The hole pointy of te post was to point out that we CANNOT get batteries

We are near the theoretical limit already, Pork Sword III..

Look at how well the steam engine has improved from Stephensons 'rocket'
I wonder why we don't use them on our railways?
