It\'s why pure O2 (or O2+N2 with no CO2) in scuba breathing apparatus
is a bad thing: the body needs *some* CO2 to stimulate breathing.

Speaking as someone who in the early 1980s became a fully qualified
Navy open water deep sea diver and Navy diving medical officer who
trained on multiple devices using multiple gas mixtures, CO2 was
never part of any of the gas mixtures. I\'m talking about normal scuba
(compressed air) as well as special diving mixes that combine various
ratios of pure oxygen and/or pure nitrogen and/or pure helium.
Normal metabolism combined with the physiologic stress of diving plus
the work of breathing gases under pressures greater than 1 atmosphere
produces all the CO2 the brain needs to stimulate the breathing reflex.

If the exhaled air is re-breathed (combined with new air from the
cylinders) then I can imagine that the amount of CO2 that the body
produces is sufficient. The danger comes if all the exhaled air is
\"lost\" and not blended with the tank air: then you need to make sure
that the tank air has CO2 in it - which atmospheric air will do but a
mixture from oxygen and nitrogen tanks will not.

Absolutely wrong.  I wouldn\'t be alive to write this if what you say
were true.  The major health risk to a diver using a rebreather is a
failure of the CO2 scrubber, resulting in excessive CO2 in the
rebreathed air, toxicity, and a fatality if the diver can\'t surface.
Almost all rebreathers use \"nitrox\", a mixture of pure oxygen and pure
nitrogen.  I know.  I\'ve used these devices.

I should have added that in some diving scenarios, rebreathers actually
are charged with 100% oxygen.
 
You can\'t be bothered to connect them all to the decent service? In the UK, we call that sort of TV \"council telly\" - it\'s what you have when you have no money.

Which won\'t work in the US anyway because the standards are different.

Carlos, I hope you have a CO detector? It doesn\'t take a lot to go wrong

I have one in my head, it\'s called getting a headache. I don\'t waste
money on safety shit.

That\'s for CO2, fumes, and lack of O2, not abundance of CO.

CO will produce headache, nausea/vomiting and unconsciousness. Check for the
gums, fingernails and corners of eyes going cherry-red: that is caused by
carboxyhaemoglobin, in which the haemoglobin in the blood binds
preferentially with the CO, instead of the O2 which it is supposed to bind
with. Carb-haem is very bright red: much more so than with normal blood,
even oxygenated blood straight from the lungs before it has gone to the
organs/muscles.

CO2 tends to cause increased respiration because the body\'s natural reaction
is to try to breathe more in the hope of getting enough O2. It\'s why pure O2
(or O2+N2 with no CO2) in scuba breathing apparatus is a bad thing:

Um, no. Nobody puts any CO2 in diving cylinders. Pure O2 is actually toxic
over long periods. The higher the pressure you’re breathing it at, the
more toxic it is. The presence or absence of CO2 doesn’t come into it.

the body
needs *some* CO2 to stimulate breathing.

Not entirely true. We have a “hypoxic drive” to respiration but the CO2 is
a much stronger stimulus. We all rebreathe a certain amount of air because
of the “dead space” in our lungs so CO2 levels in our lungs and never falls
to zero.

I have forgotten the math for this, but anyway, it is not cheap. Copper
has never been cheap. The cheap method has always been one capacitor, to
generate a bit of a phase. Many motors use this trick. Look inside a
household fan, for instance.

I have a pair of old fans I use to cool the garage. They have a large capacitor each. I thought those were for the power factor correction? They\'re just one phase.

My heat pump\'s compressor (and it\'s fans) have capacitors across them. Again, I thought that was for PF.

My late mother relates a story from presumably the 1920s, in which she
and her sister and young brother were playing in a room with a paraffin
heater.
In the sort of trust in adults displayed by BBC audiences,, the ideas
that she couldn\'t see in front of her for black smoke, and was coughing,
didn\'t seem to create any alarm whatsoever until her father rushed in
and opened all the windows and dragged the children out.

When I was a kid most everyone had unvented gas heaters in our houses,
which burned clean. Fortunately, the houses were usually very leaky.
If the CO2 level got high, it would feel stuffy and we\'d turn down the
heat or lift a window for fresh air.

The hazard would be for the CO2 level to get so high that the gas
flames starved and started making CO. That was rare.
Current burners switch off automatically way before that.

120 degrees phase difference between the the phases.
quite a bit more than a \"bit\".

Since inductors lag 90 degrees, I thought doing that a couple of times could shove it to 120.

My parents had a scare about 20 years ago. They have a holiday cottage
in Yorkshire which is heated partly by a coke/wood stove. Some friends
were staying there and one of them woke up in the night feeling dizzy
and sick. Luckily she was a nurse and recognised CO poisoning so she got
everyone out and opened the windows. The stove flue had got partly
blocked by a bird\'s nest during the months that no-one was lighting
fires. My parents felt very guilty and bought several CO detectors. They
have also had a cowl fitted which prevents birds getting in and nesting.

Mate of mine came within an ace of killing himself. He was testing an
unvented
gas heater that was temporarily in his main room in winter. It worked fine
so
since it was quite a cold day, left it running. His DiL rang him and when
he
didnt answer a couple of times when he was expected to, came around in
person and found him unconscious. She is a senior nurse and knew what
the problem was likely to be. Pure fluke that she happened to ring him
then.

Took a long time to recover fully.

Then why don\'t they make the power station like the boiler?

Because the exhaust gasses can not be colder than the hot water output.

With a heat pump, they can. Imagine a boost converter.

I checked. These stoves do not produce it,

A properly functioning heater doesn’t make CO. The problem comes when they
stop working properly. Any appliance that burns hydrocarbons can make CO
if the air supply is restricted for any reason, fluff build up in the air
inlet.

In that case, I can clearly see that the flame is not blue and I would
do something about it.

Pah, just breathe faster. Survival of the fittest.

Ignorance isn\'t a survival trait.   Read about it, or at least think.

Not only is oxygen (molecular weight 32)  displaced by CO2, it is
displaced UPWARD because the CO2 molecular weight is higher (44)
making it a denser gas.   Unless you get out of the valley lowland,
which is
now full of CO2, you die.   That\'s what happened.

And getting out of the valley could take half an hour, if you had a
bottle of air to breath meanwhile.
Yes, the speed of the CO2 flooding would probably have been faster than
you could run.

Like smoke inhalation in a fire.

We heat our kettle with gas. All that heat winds up in the house,

Even resistive heating is better than a furnace.  Except for gas
being
cheaper for some reason.

I find it hard to believe that you don\'t realise that this is due to
the
Second Law of Thermodynamics.

I know why it happens, just not why people use a furnace with gas.
It\'s
a waste.

The highest efficiency gas fired power station is aroung 62% efficient.
Then there are 5% transmission losses.

A condensing gas boiler is over 90% efficient.

Then why don\'t they make the power station like the boiler?

Because the exhaust gasses can not be colder than the hot water output.
For heating a house 60°C or less is good. For hot water, 45°C is enough.
For a power station, you need to boil the water at elevated pressures.

There must be some kind of heat exchanger system they could use.  Or
another use for the warm gases.  Heat the neighbouring village with
steam or water?

Well, this is already done.

Have a thermal engine generator generate electricity, and use the
exhaust gases to heat the area.
