That’s what I was doing, high zinc. But my engine was fully rebuilt only a couple of thousand miles ago, so the synthetic is OK.

I just changed the engine and gearbox oils in my 1949 classic to fully synthetic. The engine now on 5-50 gets pressure up much quicker and has a much more stable pressure when driving. I did a lot of research before making the change. The gearbox should change smoother on synthetic but I haven't noticed any difference.

As a start I have looked at what our needs are. Next step after this will be to look at possible contributions from nuclear or other sources. A starting point is to look at current electrical energy consumption. Quoting from AEMO (Australian Energy Statistics, Table O Electricity generation by fuel type 2022-23 and 2023 | energy.gov.au ) Total electricity generation in Australia remained steady in 2023 with an estimated 273,106 gigawatt hours (GWh) generated. Renewable sources contributed an estimated 95,963 GWh, making up 35% of Australia’s total electricity generation, up 3 percentage points on the share in 2022. The largest source of renewable generation was solar (16% of total generation) followed by wind (12%) and hydro (6%). Fossil fuel sources contributed 177,142 GWh (65 per cent) of total electricity generation in 2023, down 3 percentage points on 2022. Coal accounted for the largest share of electricity generation, at 46% of total generation in 2023, down from 47% in 2022. These statistics cover all electricity generation in Australia, including by power plants and by businesses and households for their own use. So if the aim is to replace fossil fuel we need to replace 177,142 GWh or 65% of current production with something. But remember we are also replacing fossil transport fuel, switching from diesel and petrol to more electric. The ABS says ( Survey of Motor Vehicle Use, Australia, 12 Months ended 30 June 2020 | Australian Bureau of Statistics (abs.gov.au)) In total 33,019 megalitres of fuel were consumed, 49.0% petrol and 49.1% diesel, the relative usage of diesel has increased to be equal with petrol for the first time. 33,019 megalitres of fuel is only 3,900 GWH of electricity after considering thermal efficiency, so only about 2% of total energy needs. Perhaps we can ignore vehicle fuel in further discussion.

That is because Canada runs on hydro power. They don't call it electricity, they call it hydro. As in "our house is connected to the hydro," which just means the grid.

Taking it a step at a time, I assume no one disputes the safety angle. If we can agree on that we can move on to cost and timing.

The "facts" quoted here by the Albanese sycophants are 75% nonsense. I can post "facts" which are soundly based but get howled down each time. This has been going on for several years here. The bottom line is that I am seen to be a "denier" so everything I post is fair game. I sometimes forget that and post something, only to get beaten up again. I am a slow learner. My colleague the late Ian Hore-Lacy spent 40 years advocating for nuclear power in Australia. He ran the Uranium Information Centre in Melbourne and wrote several books. He had two science degrees. But people here would ignore his work I'm sure because he had worked for the Rio Tinto group. I wish he had lived long enough to hear Dutton today, he dreamed of nuclear getting a hearing. So, if I quote "facts" from Ian's work. how will you respond? It's like the bloke in Salem who said there are no witches. He was shouted down. "Of course there are witches, we burned a dozen last year! That is proof!"

This seems to be the labor party kumbaya thread. An ugly and dangerous place to visit.

I hope OK recovers and comes back. I don't know what his views were, but I can certainly understand the impact of negative attacks. It is quite depressing to be attacked personally for genuinely held and soundly based beliefs.

I don't know about anyone else, but I think Keith Richards was there. -
It would be an anus horribuls.

I don’t even know the names of the teams after 46 years in Victoria.

That sort of nonsense is going to tip the balance in favour.

He played an IRA guy once. A really moving part. I have forgotten the name of the movie. ( not the Eagle has Landed) -
You need a Lab test. They are a great dog

This month was $240 for me. Plus $145 for gas.

I nearly hijacked OME's blog to respond to a highjacked theme, but I will continue here. This is the difference between prediction and actual events. Is the number of global natural disasters increasing? Gianluca Alimonti &Luigi Mariani ABSTRACT We analyze temporal trends in the number of natural disasters reported since 1900 in the Emergency Events Database (EM-DAT) from the Center for Research on the Epidemiology of Disasters (CRED). Visual inspection suggests three distinct phases: first, a linear upward trend to around mid-century followed by rapid growth to the turn of the new century, and thereafter a decreasing trend to 2022. These observations are supported by piecewise regression analyses that identify three breakpoints (1922, 1975, 2002), with the most recent subperiod 2002–2022 characterized by a significant decline in number of events. A similar pattern over time is exhibited by contemporaneous number of geophysical disasters – volcanoes, earthquakes, dry landslides – which, by their nature, are not significantly influenced by climate or anthropogenic factors. We conclude that the patterns observed are largely attributable to progressively better reporting of natural disaster events, with the EM-DAT dataset now regarded as relatively complete since ∼2000. The above result sits in marked contradiction to earlier analyses by two UN bodies (FAO and UNDRR), which predicts an increasing number of natural disasters and impacts in concert with global warming. Our analyses strongly refute this assertion as well as extrapolations published by UNDRR based on this claim.

Bill Gates and Dick Smith are both greenies at heart. No vested interest in nuclear, it just makes sense.

One thing I would add is that the world does not have enough available mineral resources to deliver the "electrification" being forced upon us by left wing politicians. That is not just cars, but grid, generation and storage. So, it cannot physically happen. Once that is accepted, we can make more realistic plans for the next 25 years.

The objection to nuclear because it needs lots of water must be a furphy. It is a steam generator, so would use the same amount of water as a coal or oil fired generator. Edit,,, just found this: Coal, on average, consumes roughly the same amount of water per kilowatt-hour as nuclear, while it does very more heavily depending on the type and age of the individual power plant.

Or the upright bikes.

In Australia it would be called a Froot.

My only experience of electric was not that they were quieter. Apparently the tyres are hard and high pressured, with low profiles, to reduce rolling resistance, which makes road noise. My ICE car can have a softer, quieter tyre. But that is a very small sample of experience.
