We'd be mugs if we put all our electricity generation eggs in one basket. We should make use of what has proven to be able to produce electricity - solar, wind, gas/coal. Australia is lucky in that it has the open spaces on which to erect solar arrays. More so, in urban areas where most of the electricity is going to be used, there are hectares of roof space. I see the solution as a divide between those two. I'm not overly keen on wind generation, which seems to be overly expensive to set up the generators. Even when commissioned, not all the generators in a unit are working at the same time. The question of transmission lines baffles me. We already have power grids covering a high percentage of users. What prevents the wire carrying the output from a renewable generation site from being connected to an already existing transmission line?

Go to any food court in a shopping centre and you'll be lucky to find a pie-eater. They are always available, but most people will be eating a kebab, Indian or Chinese. Should we lament the demise of pies? I don't think so. If I'm correct, pies (and pasties) are British foods. That's where we got the tradition of eating them. But since we opened our gates to all-comers, the basic foods in Australia have evolved as the culture has evolved. In the 21st Century, we should consider ourselves the "New Australians", who have evolved from the Anglo-Irish "Old Australians" through cultural cross-breeding.

I wouldn't worry if I was you. In South West Sydney there are new suburbs which are being referred to as Mumbai or Kolkata because there are so many Indians living there. At the end of June 2022, 753,520 Indian-born people were living in Australia, more than twice the number (355,380) at 30 June 2012. After the United Kingdom, the Indian-born population is the second largest migrant community in Australia, equivalent to 9.8 per cent of Australia's overseas-born population and 2.9 per cent of Australia's total population.

Contact your bank. They will have a fraud unit to look into it.

I posted that video simply to show the London bus on a skid pan, which is something you mentioned. Of course there are many more skills a bus driver needs to learn before setting out to drive the public. -
It will be interesting to see if it is Trump or Musk who is Time's "Person of the Year" for 2025. It seems that the criterion for the selection is the perceived historical significance of the nominee. These two certainly meet that criterion. Most choices for "Person of the Year" have been historically important individuals, many of them infamous rather than internationally popular (Adolf Hitler was 1938's "Man of the Year", Stalin, 1939 and 1942, and Ayatollah Khomeini won in 1979).

Let's talk about Artificial Intelligence

The Great Debate offering reads like an article in a popular aviation model. Quite pleasant to read. I like the humorous asides. I'm reading some short stories by P G Wodehouse at the moment. I wonder what AI would produce if asked to tell a story in his style. -

Nah, That was just cheeky banter. No offence detected.

Short or long, it was wrong. Yes, no and maybe. We have to differentiate between the process of slowing the rotation of the wheel, and the effect of that slowing on the deceleration of the vehicle. The function of an ABS system is to control the rotation of the wheel assembly in order to allow the tyre to develop an amount of sideways force which is the force that results in steering. If the wheel assemblies of a moving vehicle stop rotating, the tyres will slide on the surface. A sliding tyre cannot produce any steering force. In fact, if you are in brake lockup, it is possible to turn the steering wheel from left to right and back without causing the vehicle to change direction. An ABS system is designed to release the hydraulic pressure being applied to the brake cylinders before the pressure reaches a point where the rotation of the wheel stops. The system is also designed to return the pressure thereafter so that the critical point is reached. Then the cycle begins again. That is why, if you stand on the brake pedal and keep standing on it, you will feel a rapid shuddering of the pedal as the pressure changes up and down rapidly. -

GON, there's an old saying, 'a cobbler should stick to his last'. It warns against involving oneself in areas that one lacks knowledge or experience. No it wasn't. It is designed to allow the braking system to slow the rotation of the wheel until the point of lockup, after which the tyre will slide on the surface. By allowing some rotation in the wheel. there is some tyre/surface friction remaining to allow the tyre to create a steering force, thus the vehicle can be steered, which is not possible if the tyres are sliding on the surface. The composition of tyres does affect the tyre/surface coefficient of friction. Harder compounds lead to lower coefficients. That's why the tyres used for racing are "softer" than regular passenger car tyres. Since ABS deals with brake application, the hardness of the tyres is not a factor in its effects. -

And there is the flaw in your flawless argument. The coefficient of friction between a tyre and a road surface is not consistent. By that I mean sections of road surface of the same construction can have different coefficients of friction due to the amount of other material on the surface such as dust, oils, water etc. The onboard computer of a car would not know what that coefficient would be at any instant, so it could not calculate a braking distance. -
Santorini's eruption did create a massive tsunami. Some think that the tsunami was the source for the Noah story, but that story has its origins in the valleys of the Tigris and Euphrates in Mesopotamia. ("Mesopotamia" comes from the ancient Greek words mesos ("middle") and potamos ("river"). It literally translates to "land between the rivers". )

That whole northern coastline of the Mediterranean is the boundary between two plates. It's a pretty geologically active area. We are talking about a volcano near Kolumbo, but we haven't mentioned Vesuvius, which blew up around 1800BC, nearly contemporaneously with Santorini and again in 1944, or Mount Etna which is pretty active. Then you have those earthquakes in Turkey.

Getting back to the original point of this thread, the dumb buggers at ANCAP have decreed that this anti-collision device has to be fitted to new cars. For what? To prevent rear-end collisions. Think about the circumstances when rear-enders occur. It is usually soon after rain begins after a dry period. The accumulated muck on the road surface get wet and slippery and drivers who are used to driving in a dry road that provides a higher degree of friction between tyres and the surface, drive in a similar way, but the degree of friction is much less and stopping distance increases. From what I understand, these "safety devices" will apply the brakes if a collision is imminent. That is most likely to induce a skid and the vehicle will slide into the one in front. I can't see the device preventing rearenders. However, these twits at ANCAP are inflicting added costs and complexity for the manufacturers and cost increases for the consumer. I wonder if these "experts" ever drive motor vehicles to work, or do they catch a bus. -
Apparently the paperwork to start the process is being drawn up by the Democrats. It remains to be seen how pizzed off the Republicans are to make them back the Democrats and impeach him.

The claim by the media that a volcanic eruption is imminent is clickbait. In the article Red posted above, a respected British volcanologist rejected the idea of an eruption. While the reports of earthquakes are reliable, they are caused by the collision between the tectonic plate under Africa and the Eurasian plate. The African plate's speed is estimated at 2.15 cm (0.85 in) per year. It has been moving over the past 100 million years or so in a general northeast direction. It is pushing closer to the Eurasian plate, causing subduction where oceanic crust is converging with continental crust. It is true that there was a massive volcanic eruption at Santorini about 1600 BC. There have been more recent eruptions. These have been due to the build up of steam pressure as groundwater reaches the magma below. At present there are few indications that similar events are likely.

Jerry, In simple terms, if the market crashed, would Musk still be the richest person? How much of his wealth would represent things that he could say that he owns outright?
