Switchover 'should have been greener'

Just to bring all these discussions on the climate back to something like
being on-topic, here's an article about the power consumed by TV
equipment and especially set-top-boxes. Speaking as an electronic design
engineer, I think that those responsible for Sky boxes in particular are
a disgrace to my profession.

Still on the environment: If warning-labels had been put on analogue-only
equipment, there'd be less equipment dumped when the switchover occurs. I
see that my petition to No. 10 for warning labels has just moved above
the 100 signature level. More please. :-)

I have two Pure radis which are basically the same, one the evoke 1 the
other sonus 1. Both came with psus like bricks. The evoke psu runs cool, the
Sonus hot. Here is the strange thing. Both are rated the same but made by
different companies. So they are interchangeable. If one company can make a
psu which runs cool and is therefore more efficient, then why do they all
not do this. Obviously Pure just source these from where they get the best
deal, I doubt if this aspect ever crossed their minds.

I take it that if you swap the PSUs over, they still run cool and hot the
same, ie it has got nothing to do with the current drawn from them??

Just a thought, but is the one which runs the hottest a fair bit heavier
than the one that doesn't?. If so it may be because that supply is fitted
with an ordinary mains transformer and a bridge rectifier arrangement,
whilst another manufacturer may have taken the different approach of fitting
a more efficient SMPS inside the wall wart of the one which runs cooler.

Mains transformer powered 'bricks' needn't run hot either! It's down to how
the output DC is regulated. A SM regulator can be very cool, while a linear
regulator can get quite warm.

Sky pay the piper so he plays their tune. Sky are concerned about one thing
only and that's profit. Every time you power up a Sky box you have to endure
the incredible hypocritical tosh on 998: "If everyone turned their box to
standby it would save as much power as Birmingham." What the . . . .?

"The UK's chief broadcasting regulator has said digital switchover could
have been planned to be more environmentally friendly." Yes, very tongue in
cheek. All the leaders of men have to pay lip service to t'environment.
Meanwhile nothing stands in the way of profits.

They all bombard the little man with santimonious instructions to save a few
watts, whilst industry roars on with ne'er a care.

Exactly, in fact, I have given a friend the hot psu and the older radio now
and both are fine.

Indeed. The fact is that mankind is basically lazy and few of us "switch
off" as much as we could. We're also forgetful and sometimes find we simply
can't get to the box we SHOULD turn off because it rounds behind the TV or
somewhere equally inaccessible.

A good design needs to take the user into account and work with them and on
their behalf. I do sometimes wonder whether designers shouldn't be forced
to use the goods they design for say, a month. Then they might get the
message.

Architects should be made to live in the social housing they design, that's
for sure.

One thing I would definitely like to see Bill is the people who design and
sign road layouts allowed to be personally prosecuted in the event of an
accident where the blame can be laid firmly and squarely at their door.
