+When I was young, I was invincible.
I could run across a beach and kick a football and stairs. Who cares! Just pop up them and look like Rocky in the scene that made him famous.
Nowadays, I can barely walk up or downstairs without doing it very, very carefully. Such is life.
Add a commentIf you believe in the tooth fairy, or vote Green, you probably believe that hydrogen is the magic rainbow gas that will banish global warming, replace wicked hydro-carbons in electricity generation, fuel tomorrow’s trucks, planes and heavy equipment, and earn unlimited export income.
There is one big problem – unlike coal, oil and gas, there are no hidden pools of hydrogen we can tap. Every bit of hydrogen has to be manufactured from water or hydrocarbons using huge amounts of energy.
The energy content of liquid hydrogen is about 70% of the energy required to produce it. Burn it in a combined cycle gas turbine (energy efficiency 50%) and see that energy return drop to around 35%. Use it as vehicle fuel and see energy efficiency fall even further.
The density of liquefied hydrogen is much lower than that of natural gas - thus the transportation costs will be higher. And because the tiny hydrogen atom finds any small leak, the safety risks are very high - imagine a road accident involving flammable lithium batteries plus explosive hydrogen gas.
Most hydrogen is made directly from coal, oil or natural gas and the main process produces hydrogen and . . . more of the dreaded CO2.
But hydrogen is loved by Big Greens and little children because it has been named in a rainbow of pretty colours: grey, brown, black, green and blue.
Grey hydrogen comes from natural gas, brown from lignite (brown coal), and black hydrogen is made from black coal (no surprises there).
Green hydrogen is produced by electrolysis of water using intermittent green energy like solar or wind power. It requires heaps of fresh water and electricity neither of which can ever be fully recovered. Every tonne of hydrogen uses nine tonnes of water.

La Nina Floods have mangled the roads of eastern Australia with pot-holes, gully wash, mud and silt.
Add a commentOver the weekend, the New York Times carried a story headlined “How Australia Saved Thousands of Lives While Covid Killed a Million Americans,” written by Damien Cave. Cave claimed that Australia’s comparatively low COVID death count is down, in the main, to “a lifesaving trait that Australians displayed from the top of government to the hospital floor, and that Americans have shown they lack: trust, in science and institutions, but especially in one another.”
As a dual American-Australian citizen and resident of Sydney throughout the COVID policy fiasco, and equally as one of Australia’s most outspoken anti-lockdown economists since March 2020, seeing this coverage made my stomach turn.

Among them, out of a population of five million souls, 416,000 young Australians answered the call of duty under the banner of the Commonwealth and 295,000 served bravely on the Western Front in the mud and poppies of northern France where they paid a heavy price.

I love words and the precision that they have.
They are like snipers. If used in the right hands, our bullets called words can hit their target very accurately.
That is why the Left want to destroy our language.

Today is the 79th anniversary of the Dambusters raid. Its leader, Wing Commander Guy Gibson was awarded The Victoria Cross as a result. Gibson became one of the founders of the Pathfinder Force and transferred to Mosquitos. He was lost somewhere over the North Sea returning from a raid. It is thought that his plane ran out of fuel.

As many know, the US is confronting a shortage in baby formula that has grown quite serious. What started as complaints on Twitter of “out of stock” messages on Amazon purchases has turned into a national panic.

For many, graphic footage of Russian servicemen tortured and killed by the Ukrainian Armed Forces, and nationalist battalions, came as a real shock. But this did not surprise those who are familiar with the ‘traditions’ of Ukraine’s ‘fighters for national freedom’, as they have more than a century of history in this sort of thing.
