'[EE:] Japanese Industry 1W Standby Power - what in'
2000\11\09@035807 by David Lions

Hi,

A while ago I read here about a Japanese industry group's (?) intention for
appliances to consume only 1W when in standby mode.  Can someone tell me
what industry group this was, or basically whose idea this is?

I am doing an assignment for a subject called Technology Assessment and this
would be particularly relevant to the topic.  I couldn't find it in the
archives.

Thanks,
David.

I don't know about Japan, but the European Union (EU or previously EEC)
passed regulations a few years ago which are reducing standby power on
all electrical items in Europe. This has resulted in substantial design
changes in TV's and VCR's, with many now effectively having two power
supplies, one for the unit, and one for standby.

I'm not sure of the exact figures for Europe, but it wasn't all done at
once, but by stages.

I went to a lecture here at Auckland Uni from the prime mover of this concept. I
have alas lost all my records of who he was and I can only vaguely remember
where he was from BUT here goes.
He was from a University or Government type research centre in the U.S., I am
pretty sure it was in California and he was either next door to or somehow
associated with some well known Nuclear research facility (sorry... thats the
best I can do).
He was fiercely opposed by the U.S. Dept of Energy but was a leading light for
other countries like Japan and the EEC.

Interesting guy... I learnt how Satellite Boxes draw almost the same off as on
and the new home stereos draw like 30 watts on or off (eeeeewwww).

I will try to uncover my original records but I know he did have a web site.

There's a simple reason for satellite boxes drawing the same amount when
'on' or 'off' - they don't have any on-off switch!. All they do when you
set them to standby is turn off the RF modulator, mute the video and
audio outputs, set the box to a particular channel, and update the
display in some way - often just change the colour of an LED.

There are basically two reasons for this, firstly (and most importantly)
the broadcasters want to be able to access your subscription card at all
times - so even when you think your box is switched off, it isn't
really, it's actually set to the best channel for them accessing your
card. Secondly, it's fairly important to keep the LNB powered and warm,
if left un-powered they can suffer from condensation and damp, plus they
use simple free running local oscillators (around 10GHz) and these drift
about from cold.

Don't know if this helps, but a government run will know nuclear research
facility in California very likely means Lawrence Livermore Labs in
Livermore California.
