Carlos, I hope you have a CO detector? It doesn\'t take a lot to go wrong
with a portable stove to produce poison gas.

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.

Only because our bodies are so fucking stupid they breathe too much of it.

the body needs *some* CO2 to stimulate breathing.

Not entirely true.

It isn\'t true at all.

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.

We generate CO2 from exertion. There\'s no way we could encounter problems from lack of CO2.

CO is lighter than air, doesn\'t \'pool\' in low places. The low land

suddenly boil and burp up a cloud that covers the neighborhood.

CO, of course, WAS toxic, and \'head in the oven\' suicides were known.
That gas hasn\'t been considered safe for years; electric lights and
electrical distribution systems came about a century ago: we still get
\'natural gas\' designating that the municipal gas supplies of today are
NOT the old toxic mix. Coal gasification was abolished here in the
1930s.

The best toxic gas is good old Nitrogen Dioxide, that makes up about 80% of
the natural atmosphere.

We have no ability to sense excessive concentrations, and many people have
died due to leaking liquid NO2 bottles or leaking NO2 gas cylinders. You
just pass out and quietly die.

NO2 is noxious. N2O, on the other hand, is much more discrete. It makes
you pass out without much warning. It\'s used as an anesthetic and also
in cans of instant whipped cream. Neither is a major component of the
natural atmosphere.

They work really well here too. People are finding their smart meters
have moved them onto more expensive tarriffs without their knowledge.

That doesn\'t happen here. Someone called and the client said \"yes\".

And their true use - to cut people off when the load is too high - seems
to be being revealed

No revelation here, we knew.

Their first step was to mandatorily insert a current limiter at the
entry box, with a lead seal for not tampering. But people tampered it,
with a \"jumper\". So the next move was smart meter with current limiter
included. End of customer fraud.

I don\'t know as it does still work as an FF. I\'m not too bothered with

\"Ice forms in the fridge part\".  Refrigerated food is damaged when
frozen.  It\'s not fit for purpose.

It doesn\'t freeze the food, even milk. The ice is on the back of the
fridge part. There is a drain to get rid of water condensed there but it
freezes instead.

This happens when the fridge can not cope with the load.

It can be the fridge is simply a bad design. The evaporator or cold
surface is too small. It can be that the door is opened too many times.
That the door doesn\'t close tight. Summer (or house heating to high).
Whatever.

Remedies are lowering the fridge thermostat (higher temp). The thing is,
ice is an insulator, so the inside of the fridge will not get any colder.

Another possibility is placing a small fan (5 cm dia is enough) inside
the fridge blowing across the ice. Caveat is that this may distort the
working of the thermostat, and you have to lower it down or you convert
the fridge into a freezer.

Or, put the fan on a timer: blow for half an hour, stop for half an hour
(this is what I did).

This may put a higher load on the heat radiator on the back, if it can
not evacuate all the heat generated there. Solution would be another
small fan blowing there.

You are right, of course. Slight typo. What we are after is plain nitrogen,
N2.

What is the composition of the atmosphere currently?

By volume, the dry air in Earth\'s atmosphere is about 78.09 percent nitrogen,

Depends. Do you have 3 phase motors?

In my country house I currently have only one pump, which require
three phases.

That can be done with single phase power and a three phase inverter
(single phase input, three phase output). I don\'t know the current price
of that, though.

Typically the single phase 230 V input inverter has 127/220 V three
phase output. The 230/400 V motors are much more common.

Ah, yes. That needs a more expensive inverter.

To generate clean sine 230/400 V three phase you need about +/- 340
Vdc bus voltage. There are several methods to generate this DC voltage
from single phase 230 V, such as:

* Use a voltage doubler rectifier, since the peak-to-peak voltage is
2x325 V. Unfortunately this would need _huge_ capacitors and still the
output voltage would be flat-topped.

* Put an auto transformer in front of the voltage doubler. This would
help somewhat but would be heavy.

* Use a DC/DC boost converter between the single phase rectifier and
the DC capacitors. If a PFC is required, it is usually implemented
with a DC/DC boost converter. Adjust it lo generate at least +/- 340
V. As the DC/DC converter can be used for both PFC as well as boosting
the DC bus voltage, so not much extra cost needed.

it!

My parents bought a brand new house in the early 1970s (so 1970s technology
(*), admittedly!) which had gas-fired ducted-air central heating. And the
house was never really warm, especially at the remote end of the ducts,
where you got a feeble waft of tepid air. Even the ducts right next to the
boiler/furnace gave out tepid air, even if there was more of it. And the
house was very dusty because the constant draught kept dust circulating in
the air. Our neighbours replaced their CH system with radiators when the
boiler needed replacing twenty years later, rather than going for another
ducted-air boiler. They said to us \"at last the house is warm\".

At least our ducted-air system was fairly quiet. When we were looking for a
house a couple of years ago, we looked round one with a heat-pump/ducted-air
system which emitted a constant moaning whining noise throughout the whole
house - you couldn\'t escape from the infernal whining.


(*) The boiler was massive: about the depth and width of a typical fridge,
but about 7 feet high - a floor-to-ceiling cabinet. The only room in the
house that was really warm was the downstairs toilet which had the boiler in
it, which suggests that a lot of the heat from the burning of the gas was
wasted to the room rather than going into the ducted air.

Obviously the people that held the purses did not think like you, thus
you are mistaken.

Obviously you absolutely can\'t resist the unwashed trolling wanker\'s cock,
you troll-feeding senile dumb spick! LOL

Similar for forced-air gas furnaces, which are the most common
type of heating in the U.S (60% of American homes). Mine is
above 90%.

Do you find that forced (ducted) air central heating actually keeps the
house warm? I suppose it must work, or 60% of American homes wouldn\'t use
it!

Yes, I do. It keeps the house at a comfy 71 F (that\'s about 21.7 C).
The filters in the return-air plenum clean the air. The furnace is
about 20 years old and it\'s still performing beautifully. It is
installed in the basement; not all the ducts there are insulated,
yet enough warm air makes it throughout our single-story house to
warm even the farthest rooms.

Last year we spent about $70 on heating in February. I expect it
might be a bit more this year.

It also affords us an opportunity for central air-conditioning, for
the hot and humid days of summer.
