Ok, here goes.

AARNet accepts Mail Affiliates (MX Records) from the general public
for $1000 per annum. AUUG offers its machine-owning members (thus
usually corporate members) the same service for $250 per annum. Non-members
can still profit from the AUUG deal but pay $600 per annum. As AUUG
corporate membership costs $325 per annum, you can see why we have
only one or two non-members involved.

The Mail Affiliate service provides only registration of your host/domain
addresses in the Internet nameserver tables. It does NOT provide or cover
the cost of any kind of connection to the Internet or any other host. In
other words, you approach AUUG after you are connected to get your name
"switched on" in the Internet world.

If anyone would like a registration form, please mail me direct.

Regards,
Chris

They are not AARNet affiliates, so I don't think so.

Can the standard domestic power meter measure this out-of-phase component
accurately?  How exactly does this affect the metered cost of these
different globes (as opposed to actual power consumed)?

If you go to all the trouble of filtering the input to a switch mode supply to
make the input current waveform closer to a sinewave (nicer for the power
provider and other users on the grid, you might as well fix up the power-factor
of the PLC by adding reactive elements.

I think that PLC's have so far got through a crack in the standards (I could
be wrong). If PLC's do proliferate the country-side be prepared for the
electricity authorities to either

a) use meters that measure real and reactive power, or

b) require that households as well as industry have approximately unity
power factor. 

Either way, you'll end up paying for the "free" power currently used by
PLC's. Either by adding components to fix up the nasties or increased
electricity bills to cover the infrastructure upgrades required.

A domestic energy meter in good condition measures the energy used by the
household, i.e. the time integral of power. The power being used at any time is
the product of the voltage and the magnitude of the in-phase current component.

The out-of-phase component (+/-90 degrees) of current therefore does not contribute
to this measurement (directly). However, the consumer does lose a SMALL amount of
power in the house conductors caused by the slightly greater magnitude of the resultant
current when the power factor is poor, for a given power at the appliance.
This increase in loss is: [(|I1| ** 2) - (|I2| ** 2)] * R

 where |I1| is the magnitude of the current of the appliance with a poor power
            factor;
       |I2| is the magnitude of the current of the appliance with the same power
            consumption, but a power factor of 1 (no out-of-phase component);
        R   is the total resistance of the mains conductor between the load and
            the energy meter.

The power factor would have to be really terrible for this loss to be significant
to a householder, as R is small and I1 is not very much greater than I2 for a
power factor near 1. For small loads like flouros, the loss is negligible. To the
power provider, millions of flouros at the end of a long power line are very
significant...likewise to the environment.

I beleive there is some  mis-infomation here. (From memory of my high school,
power electrical course).  A poor power factor means the current is out-of-phase
with the voltage, caused by a inductance or capacitance load component.

The power used is still I*V at any instance, so the power consumered (by the
load) is not effected.  The problem is that because the current is out of
phase is has higher peaks, compared to something comsuming the same power
but in phase.

This could lead to the power lines needing to be larger and increase line
losses both which cost the power company.

I was told (years ago) that in Canada, power companys will cause factories
high rate if they produce a large out-of-phase current.

The main problem with 'compact flouros' is a high crest factor. I put CF in
quotes because most people mean Phillips PLC-E or equivalent. CF refers to
the tube design and base. The balast can be inductive, capacitive, electronic,
and may also be intergrated into the unit.

Back to the crest factor... The PLC-E and friends use a switch-mode power
controler to feed the tube. At the mains side of these electronics is a diode
rectifier and a storage capacitor. Current only flows when the instantainious
voltage from the mains is greater than the cap voltage. When this condition is
met, current flows into the cap, recharging it to peak voltage. When the voltage
drops from peak, the diode shuts off and the current stops. Hence the 20W tube
actualy draws ~100-150W peak, 50 time per second. IE, the current is a series
of spikes, rather than a steady sinewave.

The question od reliability, I have used PLC-Es at home, no failures yet...
Osrams at a site I work at, ~100 installed 9 monthes ago, 10 failed in 2 weeks,
currently seems to go at about 1 per week.

PS These lamps can take a minute or two to come to full output, this may be
a problem for some.

As I said, cost and size are the problem here. Also eficency. 20W on top of a
5KW PSU is nothing, add 20W to your 9W CF and you would not think so.

There is no power involved, free or otherwise. There are 2 costs to the supply
though. The first is an effective increase of the frequency that they are
supplying power at. The second is the realy nasty one, the DC component will
increase the corrosion of equipment 1000x or so. This one they will scream
blue murder about... Can't say I blame them.

The Crest Factor *WILL* increase the losses in the net, especialy in trans-
formers, but will probably result in a lower total demand. Also don't forget
2 other factors; 1) the integrated balast units will go away after a few years,
people will install a decent ballast in the fitting. These are still scandal-
ously expensive and hard to get. Also there are few luminairs designed for PL
base flouros yet. 2) The PF problem is best addressed on a net wide basis. It
may be possible to use the 'nasties' from the flouros to correct PF problems
from other sources. At the worst, it would mean a small increase in the current
rattings of the mains, and a 1-3% increase in the tarif to 'recover' the 'lost'
power.

Also, lighting may radicaly change in the next few years. Light piping and
Tungsten-Halide arcs are one that comes to mind.
