TapDoubtful Which? Recommendation

23 Jan 2008 14:25 by Rick

The Feb 2008 issue of Which? Magazine (page 64) has a recommendation for the Sava Plug which, it is claimed, can “reduce the power a freezer uses by around 25 per cent and a fridge freezer by about 7 per cent”

This is a letter I sent to the magazine today:—

Dear Which,

I am surprised to see (Feb 2008, p64) that you recommend the Sava Plug. I have seen no independent technical review which justifies its claims. The company are cagey about how it actually works but it can be inferred that it does some Power Factor correction. This is an industrial technique which adjusts the apparent power usage (VA) to match the real power (Watts) by correcting the phase of the load. This is effective when the load is heavily inductive such as large electric motors. This is a good reference
http://en.wikipedia.org/wiki/Power_Factor_Correction

There are two problems with this in a domestic situation which make it near useless. First, the inductive load of a freezer or fridge is small compared to industrial use so little savings will be made. Secondly, and most importantly, domestic customers, unlike industrial users, are billed in KW Hours anyway so no correction of the power factor is going to make the slightest difference to them.

Yours faithfully

TapIngredients

22 Jan 2008 09:29 by Rick

To most children, it seems, ingredients are the list of things on the side of the jar, mostly to be sneered at, so it will be a bit of a surprise when they are required to take some into school for cookery lessons. It may also be a bit of a surprise to their parents, who have missed out on a generation of practical home management education. So I think that when they are re-introduced, the schools will have to provide the basic raw materials as many home “kitchens” will not have them—not due to poverty but from lack of use. This may not be a bad thing. I recall taking stuff into school which was all mixed up by the time I arrived and the finished product was mangled and unrecognisable before I got it home anyway. Basic ingredients, in most cases are cheap, but the kids will miss out on discovering this unless “shopping lessons” are also included. I know I would have benefited from being taught how to recognise a good piece of meat then perhaps I wouldn’t be attracted to the pink water filled sponges we are offered in the shrink wrapped packets.

TapDonor card

16 Jan 2008 09:37 by Rick

For longer than I can remember, I have carried a Donor Card in my wallet—I have just looked and mine is dated 17 Apr 1986. They were easy to get and quite high profile; on the counter in doctor’s surgeries, dentist’s, blood donor sessions, even non medical places like pubs, newsagents etc. sometimes had them.

Today they are saying that there are nowhere near enough donors and perhaps we should change over to an opt-out system where permission to donate is assumed unless you have made a declaration that you do not want to. I don’t disagree with the idea but in passing I picked up another clue—the NHS Organ Donor Register. I had never heard of it! Is it now true that it is no longer good enough to carry a card but you have to be signed up to some online database? I don’t think I like that idea*. Perhaps that is why the number of available donors is so low.

* I have had a look at the registration web site and, despite the announcement that it uses Digi-Sign and so is secure, that is an illusion. The information required is Name, DOB and Address. This is fairly public information; anyone could fill this in. DOB is a bit harder to obtain, but is not fully private.

TapValue

9 Jan 2008 11:43 by Rick

This morning, Sir Stuart Rose said

Marks & Spencer does not trade on price alone, but on value which is quality times price.

I know it would have sounded daft, but if you can give a metric to quality at all then value would be quality divided by price.

TapHand baggage

7 Jan 2008 13:34 by Rick

So today they are announcing that you will now be able to take more than one piece of hand baggage on board aircraft, and that people will be confused because you won’t be able to at some airports. So what is new? You have confused us already by implying that previously we could take more than one. If you can remember that far back, you will recall that, except for expensive and scheduled flights, the airlines would only allow one bag anyway, so what has changed, then or now? It is the airports that keep changing the rules (prompted by government) but it is the airline that affects most people.

P.S. I have never really understood why ladies’ handbags don’t seem to count, it is almost as if they were as invisible as Big Issue salesmen.

TapLong live the Queen

21 Dec 2007 13:20 by Rick

Today, the Queen becomes the longest living British monarch, ever. She overtakes Victoria as the previous leader who was a little ahead of George III. Despite his ill health, he lived to be 81 years 7 months. Richard Cromwell, however, has so far beaten them all, surviving to the age of 86.

TapFuddle

10:35 by Rick

Yesterday, my work colleagues Oop North had their Christmas Fuddle. Until they used the word, it was not one that I had come across. The dictionary meaning relates to confusion caused by alcohol, preferably lots of it (which generally suits them) but this doesn’t match yesterday’s event which was necessarily sober and planned.

What they have is an indoor bring-and-share picnic. As far as I can tell, this meaning of the word is localised to Derbyshire and perhaps Nottingham. We tried to organise one Daan Sarf last year but it was a bit of an embarasing failure so we will studiously ignore each other as usual this time.

TapSilence is not golden

30 Nov 2007 10:33 by Rick

We have never lived in a time when so much information is available to the public. We are surrounded by newspapers, radio, TV, internet, books and magazines, all telling us what is going on and what it all means, but is it believable and which do you believe? We are expected to make up our own minds, that is the principle of democracy, but is that possible when there is no apparent objectivity?

In a typical news story you get two or more sides arguing it out. On the defensive is often the government, particularly at the moment with Mr. Brown’s remarkable run of bad luck. On the attack, not surprisingly, are their political opponents out to score points, discredit the incumbents and sway public opinion when it comes to an election. You might think that the press was impartial but, disregarding their political leanings, their primary objective is to sell newspapers and increase ratings and the more sensational they can make a story the longer it will keep running. I was glad to note when my children were in school that they were taught to look at historical documents and consider possible bias, whether it is in letters, news sheets and even public records.

Whilst searching for some information I came across another aspect of the debate—silence. This is seen quite often in public scandals, whether to keep quiet in the hope that the critics will just go away or because the people who do know something are bound by official secrecy. Sometimes it is to save expense in dismissing frivolous accusations, or to give them more publicity than they deserve. In others it is thought that to by saying anything, they would incriminate themselves. The silence of the news media is much more mundane; if they think that the public are not interested or it would put them out on a limb then they won’t report it as it won’t sell. Another unexpected source of silence is apathy, the thought that no one is interested and web sites allowed to rot and die.

The public is not well served by silence. There are some things so big and important that the world needs to know the truth in an unambiguous fashion. The 11 Sept 2001 attack in America is one of them. Even the most cursory search of the internet reveals that there are countless conspiracy theories around, from the extreme nutcases to campaigns headed by quite eminent and apparently sane people. Counter to this there is very little. Excellent analyses are hidden on schools sites and popular science magazines. Perhaps it is all hot air but it creates a slant which is bound to attract attention and undermine the policies that stem from the incident so, I believe, the authorities are foolish to ignore it.

TapWhat is terrorism?

29 Nov 2007 10:49 by Rick

We used to think we know what this word meant. It was the Mau-Mau, PLO or the IRA—i.e. indiscriminate violence by non-governmental organisations for the purposes of destabilising legitimate government. This could be entirely internal or unofficial action from other countries. Even if your allegiance called them freedom fighters, it is legitimate for the state to defend against it.

Since the recent troubles started (let us say since September 2001 for convenience) many new laws have been introduced here and abroad for the “prevention of terrorism”. However I have noticed that the definition seems to be widening. Recently the RIPA legislation has been used against Animal Rights Activists—is that terrorism. Yes, I know that sometimes their methods are similar but the objective is very different. This is not the only example where laws introduced for the fight against terrorism have been used for other offences.

While we are at it, why should terrorists be treated any differently to other offenders. Perhaps it is true that, due to its nature, it requires different methods to detect and police but once caught, surely the age old principles of justice should be sufficient to prosecute them. Things like innocent until proven guilty; not detained without being charged; right to a trial before a jury of peers etc.

TapWhere have all the $$$ gone?

5 Nov 2007 10:10 by Rick

If a bank like Citigroup can lose $11Bn in under secured loans, where has it all gone? The money was paid for the houses in the first place and now they are worth less so presumably there are a lot of house builders now rolling in loot—or doesn’t it work that way?
