Interested in minimising human footprint and maximising habitat for wildlife. That will require plenty of science and engineering and a complete rethink of the global food, transportation, energy and materials infrastructure. ie., pro-nuclear vegan.

06.10.2025 06:58 β π 0 π 0 π¬ 0 π 0In conclusion, while junk food advertising bans are an obvious evidence based strategy if you are serious about tackling all manner of diseases, there is no evidence I know of that advertisers give a damn about the consequences of their work.
18.05.2025 02:28 β π 0 π 0 π¬ 0 π 05. The ban on adverising tobacco worked to reduce smoking without requiring a ban on the activity. So that's good evidence that a ban on advertising can be effective.
6. So the ban is evidence based. 6/7
4. As Australian pig meat consumption has risen during the past 30 years, so has the number of early onset cases of bowel cancer. As Australian's have gotten richer, expensive meats (like salami) are more affordaable. 5/7
18.05.2025 02:28 β π 0 π 0 π¬ 1 π 0here's what happened to bowel cancer rates when Japan started to eat these meats ... 20,000 cases per year before growing to 150,000 cases per year after. 4/7
18.05.2025 02:28 β π 0 π 0 π¬ 1 π 03. 15,000 Australians are diagnosed with bowel cancer each year, with 30% being dead within 5 years. How many of those are due to red and processed meat? Hard to say, but bowel cancer is unusual in countries eating little to no red and processed meat. Also ... 3/7
18.05.2025 02:28 β π 0 π 0 π¬ 1 π 0But the ban is obviously evidence based:
1. Advertising works. I presume AANA accepts this as a premise. If not, I'm sure they could provide "evidence" in the usual bullshit way that advertisers do.
2. Processed meat causes bowel cancer.

There was a recent panic among advertising bureaus about a ban on junk food ads set to come into force in July 1st in South Australia. An advertising lobby group (AANA) called for "evidence based" decisions; singling out ham as a poor struggling victim of the nanny state. 1/7
18.05.2025 02:28 β π 0 π 0 π¬ 1 π 0The nuclear waste panic is one of many ways to push up the price of nuclear power and drive mining the ocean for battery metals, or Indonesia for nickel. Or perhaps you don't understand how mind-numbingly complex a high penetration wind+solar+battery grid is. There is no net-zero without nuclear.
18.05.2025 02:22 β π 1 π 0 π¬ 0 π 0enough for you to handle the waste safely. Storing nuclear waste or anything else, for 500 years, is a pretty trivial problem. Of course if people don't know anything about radation, you can sell them any kind of snake oil about its risks and make a mint building a "gold plated" repository. 3/4
18.05.2025 02:22 β π 0 π 0 π¬ 1 π 0"But doesn't it stay dangerour for a 100,000 years?" The only warning required after 500 years, is "Don't ingest". There are 3 main kinds of radiation, alpha, beta and gamma, it is only the last that can harm you from a distance and after 500 years, the gammas have decayed .... 2/3
18.05.2025 02:22 β π 0 π 0 π¬ 1 π 0A friend sent me this from Germany. It looks like a normal, rather old, house, but it could be a high level nuclear waste storage building. Had you used this house to store a standard nucear waste storage cask in 1549, then by now the waste would be safe to handle. 1/3
18.05.2025 02:22 β π 0 π 0 π¬ 1 π 0Lastly, Spains nuclear fleet was only operating at half power. Some was offline because the market doesn't pay for "blackout prevention". Had all the nukes been running, there would have been no blackout because the inertia would have been much higher. 6/6

If Spain installs synchronous condensers, you will know that the Spanish Prime Minister (just like his SA counterpart) simply lied in saying the blackout had nothing to do with renewables. 5/6
08.05.2025 01:07 β π 0 π 0 π¬ 1 π 0Automatic load shedding blacks out small areas to prevent a total collapse. You need a few seconds for these to kick in.
5. South Australia spent a couple of hundred million installing 4 synchronous condensers to lift the inertia. 4/6
4. In both cases. The low inertia due to the replacement of synchronous generation by wind and solar meant that the automatic load shedding processes didn't have time to function. 3/6
08.05.2025 01:07 β π 0 π 0 π¬ 1 π 02. In SA, the interconnector to Victoria tripped (shutdown). In Spain the interconnector to France tripped (taking out an extra 2.5GW of power).
3. In both cases such events would have normally passed without notice. The Final SA report cited 3 previous similar events (larger). 2/6
The recent Spanish blackout and the 2016 South Australian blackout are remarkably similar (except for scale).
1. An event caused a loss of generation. In SA it was 456MW from storm damage to transmission towers. In Spain the precise cause is yet to be determined. 1/6
I'm looking forward to chatting with these legends of nuclear advocacy on Monday morning!
Australia's bitter partisan debate has drifted far from the point: cleaning up our energy system. Come along for a refreshing look at what this clean, reliable energy source can offer us.

Everyone seems to be framing Trump's freeze on federal grants as a Constitutional fight over powers of the purse & whether presidents can disregard Congressional appropriations. It is that. But also at stake is the fundamental validity of government contracts! I see much less discussion on this... π§΅

Or perhaps I'm wrong. Maybe the problem is that politicians are all homeowners with a massive conflict of interest. 6/6
31.01.2025 10:00 β π 0 π 0 π¬ 0 π 0Governments will be helpless because the 65% of the population who are homeowners/buyers are a formidable and very selfish voting block. You can see this every time Governments try to ameliorate the impacts that big rooftop systems are having on the grid. 5/6

There biggest day was today (Friday), they output 400 MW over the middle of the day. The previous 6 days they were almost entirely locked out by rooftop solar. 2/6

Rooftop solar will kill any clean #energy transition. It's already happening in South Australia. Look at the chart. There are 735MW of solar farms in SA, but in only one of the last 7 sunny days have they sold much electricity. 1/n

Eat the invaders? But which ones? We invaders have been eating invaders ever since we arrived. If we had been eating native wildlife, it would be long gone.
