I have sat by for a number of years frustrated at the rubbish being put forth about carbon
dioxide emissions, thermal coal-fired power stations and renewable energy and the
ridiculous Emissions Trading Scheme.
Frustration at the lies told (particularly during the election) about global pollution. Using
Power Station cooling towers for an example. The condensation coming from those
cooling towers is as pure as that that comes out of any kettle.
Frustration about the so-called incorrectly-named man-made ‘carbon emissions’ which
of course is Carbon Dioxide emissions, and what it is supposedly doing to our planet.
Frustration about the lies told about renewable energy and the deliberate distortion of
renewable energy and its ability to replace fossil fuel energy generation. And frustration
at the ridiculous carbon credit programme which is beyond comprehension.
And further frustration at some members of the public who have not got a clue about
thermal Power Stations or Renewable Energy. Quoting ridiculous figures about
something they clearly have little or no knowledge of.
First, coal-fired power stations do NOT send 60 to 70% of the energy up the chimney.
The boilers of modern power stations are 96% efficient, and the exhaust heat is
captured by the economisers and reheaters and heat the air and water before entering
the boilers.
The very slight amount exiting the stack is moist as in condensation and CO2. There is
virtually no fly ash because this is removed by the precipitators or bagging plant that are
99.98% efficient. The 4% lost is heat through boiler wall convection.
Coal-fired Power Stations are highly efficient with very little heat loss and can generate
massive amount of energy for our needs. They can generate power at an efficiency of
less than 10,000 b.t.u. per kilowatt and cost-wise that is very low.
The percentage cost of mining and freight is very low. The total cost of fuel is 8% of total
generation cost and does NOT constitute a major production cost.
As for being laughed out of the country, China is building multitudes of coal-fired power
stations because they are the most efficient for bulk power generation.
We have, like, the USA, coal-fired power stations because we HAVE the raw materials
and are VERY fortunate to have them. Believe me, no one is laughing at Australia –
exactly the reverse, they are very envious of our raw materials and independence.
A major percentage of power in Europe and U.K. is nuclear because they don’t have the
coal supply for the future.
Yes, it would be very nice to have clean, quiet, cheap energy in bulk supply. Everyone
agrees that it would be ideal. You don’t have to be a genius to work that out. But there
is only one problem—It doesn’t exist.
Yes – there are wind and solar generators being built all over the world but they only add
a small amount to the overall power demand.
The maximum size wind generator is 3 Megawatts, which can rarely be attained on a
continuous basis because it requires substantial forces of wind. And for the same
reason they only generate when there is sufficient wind to drive them. This of course
depends where they are located but usually they only run for 45% -65% of the time,
mostly well below maximum capacity. They cannot be relied upon for a ‘base load’
because they are too variable. And they certainly could not be used for load control.
The peak load demand for electricity in Australia is approximately 50,000 Megawatts,
and only small part of this comes from the Snowy Hydro Electric System (The ultimate
power Generation) because it is only available when water is there from snow melt
or rain. And yes, they can pump it back but it costs to do that. (Long Story).
Tasmania is very fortunate in that they have mostly hydro electric generation because of
their high amounts of snow and rainfall. They also have wind generators (located in the
roaring forties) but that is only a small amount of total power generated.
Based on a average generating output of 1.5 megawatts (of unreliable power) you would
require over 33,300 wind generators.
As for solar power generation, much research has been done over the decades and
there are two types. Solar thermal generation and Solar Electric generation, but in each
case they cannot generate large amounts of electricity.
Any clean, cheap energy is obviously welcomed but they would NEVER have the
capability of replacing Thermal power generation. So get your heads out of the clouds,
do some basic mathematics and look at the facts, not going off with the fairies (or some
would say the extreme greenies.)
We are all greenies in one form or another and care very much about our planet. The
difference is most of us are realistic. Not in some idyllic utopia where everything can be
made perfect by standing around holding a banner and being a general pain in the
backside.
Here are some facts that will show how ridiculous this financial madness the government
is following. Do the simple maths and see for yourselves.
According to the ‘believers’ the CO2 in the air has risen from .034% to .038% in air over
the last 50 years.
To put the percentage of Carbon Dioxide in air in a clearer perspective: If you had a
room 12 ft x 12 ft x 7 ft or 3.7 mtrs x 3.7 mtrs x 2.1 mtrs, the area carbon dioxide would
occupy in that room would be .25m x .25m x .17m or the size of a large packet of
cereal.
Australia emits 1 percent of the world’s total carbon Dioxide, and the government wants
to reduce this by twenty percent or reduce emissions by .2 percent of the world’s total
CO2 emissions.
What effect will this have on existing CO2 levels?
By their own figures they state that the CO2 in air has risen from 0.034% to 0.038% in
50 years.
Assuming this is correct, the world CO2 (in the air) has increased in 50 years by 0.004
percent.
Per year that is 0.004 divided by 50 = 0.00008 percent. (Getting confusing – but stay with
me).
Of that, because we only contribute 1%, our emissions would cause CO2 to rise 0.00008
divided by 100 = 0.0000008 percent.
Of that 1%, we supposedly emit, the government wants to reduce it by 20% which is
1/5th of 0.0000008 = 0.00000016 percent effect per year they would have on the world
CO2 emissions based on their own figures.
That would equate to an area in the same room, as the size of a small pin!!!
For that they have gone crazy with the ridiculous trading schemes, Solar and roofing
installations, Clean coal technology, Renewable energy, etc, etc.
How ridiculous is that?!
The cost to the general public and industry will be enormous. Cripple and even closing
some smaller business.

To the Editor I thought I should clarify. I spent 25 years in the Electricity Commission of
NSW working, commissioning and operating the various power units. My last was the 4
X 350 MW Munmorah Power Station near Newcastle. I would be pleased to supply you
any information you may require.

THE REAL REASON FOR CLIMATE CHANGE:
The warming from the Sun is cyclical, it’s NOT constant. The distance of where you are from the Sun is constantly changing because both the Earth’s orbit around the Sun is irregular and the Sun itself wobbles due to the combined gravitational pull of all the planets together. Look at the Schwabe solar cycle of 11 years, the Jose solar cycle of solar Inertial Motion of 179 years, Eddy Solar Cycle of 1000 years, the Bray-Halstatt Cycles of 2300-2500 years, then look into the three Milankovitch Cycles.
Short to medium term climate change:
Solar Inertial Motion: the combined mass of the planets also moves the position of the Sun through their combined gravitational pull, meaning the Sun moves around following the ever moving barycentre of the Solar system rather than being in a fixed central point in the middle Solar System. That is the key thing to understand: the Sun is moving around, wobbling in spiral like motion as it travels, it is not stationary. Once you understand that all medium term climate change can be explained simply because of the Sun’s changing distance from the Earth.
None of this has anything to do with humans. None of this has anything to do with CO2. The models of the Solar System you grew up believing as a child were gross over simplifications. They conditioned you to believe that the Solar system has a fixed Sun position with a regular Sun activity with regular orbits, of which the Earth is one. Yet that is not the reality: not only the earth both tilts and wobbles as it orbits, but the orbit is a changing ellipse not a perfect circle, meaning the distance from the Sun is not constant. These are the three Milankovitch cycles. Also other planets have irregular orbits.
The combined effect of all these irregular orbits together pulls the Sun off centre of the solar system into the barycentre. A wobbling Sun is the real reason for short to medium term climate change, and an irregular earth orbit, tilt and wobble is the reason for long term climate change.
And this is just the beginning of the story of irregularity in the Earth’s orbit around the Sun, then there are cycles of Sun activity, making it stronger and weaker according to how close to the 11 year cycle of magnetic poles flip it is, next being in 2024, and how many Sun spots & Solar flares we are exposed to.
Then you need to factor volcanic activity, the Hunga-Tonga Hunga underwater volcanic eruption of January 2022 increased the water vapour in the stratosphere by 10%, this in itself will cause considerable warming of the planet in most regions.
It’s definitely not a simplistic neat black and white story of CO2, a minor greenhouse gas, as 95% of the earth’s greenhouse gases are constituted by water vapour instead.
Humans have no power to determine either the orbit of the Earth around the Sun or the Sun’s internal & external activity, or the water vapour in the atmosphere.
Life adapts much more easily to higher temperatures and increases in CO2, particularly plants, vegetation, trees, plankton& phytoplankton, than it does to decreases in CO2.
The real danger is a decrease of CO2, and a decrease in temperature, not an increase in either.
Once again, we have been deceived by a systematically corrupt scientific funding system linked to oligarchs interests.
CO2 was always a control knob for economic prosperity, not climate.
