Electrifying the trucks and heavy machinery that use most of Australia’s diesel would be a sensible, long term beneficial action to help adapt to fossil fuel supply issues and global warming. It would also strengthen our economy.
Fortescue Mining is doing it. Why doesn't the federal govt encourage it?

There always are some & you can differentiate between the avaricious corrupt business candidates and the nazis. Put the nazis last and you improve the chances of a non-nazi winning. That's why, in Australia's compulsory STV system, not viting is always irresponsible. BUT generally "they're all the same" is a line spread by conservatives- part of "there all the same, the liberals are just lying about it" [so dont vote liberal because it wont help, they're liars & where they say they'll do things its dangerous]. It's been a conservative talking point since the 1980s.

@AkaSci@fosstodon.org This is why NASA avoids launching into clouds. From background knowledge I'd guess that a rocket exhaust plume provides an easier path to ground than plain air, making lightning strikes on space craft relatively high probability.

I love Australia's "compulsory" voting. We had 90.7% turnout at our last federal election. The Australian Electoral Commission works hard to enable people to vote, unlike the US where they appear to work to make it hard to vote. Our previous election, I was on the verge of getting postal voting papers sent to Birdsville, population 120 & 350 miles from the nearest meaningful population. My trip got cancelled & I ended up voting 150 miles from home, without any prior arrangement, with no difficulty at all, because I was back in my home state.

@mattmcirvin@mathstodon.xyz @asakiyume@wandering.shop @rgammans@dice.camp @janeishly@beige.party I think I used one of those, briefly, at school. 1975 I think. At that period my high school had, for a year, a 16k-word PDP-11/10 running BASIC on two teletypes & a VT52 CRT terminal. I've watched the blinking console panel lights & flicked the bootstrap loader (in octal) into the front panel switches, before it read the loader program & then BASIC interpreter from paper tape on the teletype - 45 minutes at10 characters per second! That's a slow program load time! I used the first 32 bit version of Unix in March 1980. I carried programs on boxes of punch cards across to the computer centre in 1980-81 summer holidays. I worked professionally on the old usenet/interconnected networks from 1984, while working at Melbourne University. When I was 10, I had a week with a PDP-8 at a nearby school. 4k of 12 bit words, FOCAL language. I worked with someone who was in the first Computer Science university intake in the world, the year I started kindergarten & was friends with a lecturer who worked with Australia's first computer, with mercury acoustic delay lines as main memory - a bit like "bubble memory" of the 1970s, but volatile & chemically toxic. I'm 64.

@cliffordheath@mastodon.social My mother in law's last Sydney to Melbourne train, in February, was 3 1/2 hours late, most of the delay in Victoria. We do need to improve this. The website didn't give meaningful information once it was later than the train's scheduled arrival time, which was difficult because she has Altzheomers. The website issue was likely caused by the challenge of matching equipment position pings with scheduled services when they are badly off schedule. I've worked with similar systems & it's tricky. It's made worse by long delays between stations because the system only gets timing information when it reaches a station, so a 3 hour delay between stations doesn't update the ETA until it finally gets to a station! Eg it's 6pm. The train hasn't reached Wangaratta, but it's still "on time" for a 6.30pm Melbourne arrival (no, it's 2 1/2 hours from Wangaratta to Melbourne)

@mackayim2022 "why is the detection signal higher in kids when, as I noted, kids hospitalisations aren't also rising steeply" I hadn't noticed that point. And my thought doesn't explain the rise in proportion in 2026 vs 2025, but to exclude the null hypothesis I'd want the numbers for the same year segment (school's back, kids in childcare get sick in an effect visible to my childcare teacher's experience; non parents get sick in winter - the 2026 effect may vanish by December) and to see absolute numbers too. I had COVID in Nov 2023, with 2 Royal Melbourne Hospital ED visits & my RATs were the only testing.

We Australians were horrified when the UK voted down a referendum to switch to preferential/instant run off voting, partly due to a scare campaign that "the wrong person" sometimes wins. Despite our preferential system, our Greens very rarely win a seat except in multi-member electorates, which is mostly upper houses including the national Senate, where they sometimes hold the balance of power. So our left also struggles to be heard, especially as our "Labor Party" has moved centrist & inactivist. .

@alexkidman Plain hybrids are just a fairly efficient petrol car & I wish media & statistics would not group them under "electrically powered" or similar. Plug in Hybrids are expensive to maintain & most spend most of their time running as plain hybrids (plug in battery near flat). To get benefit you have to recharge every day you use it. Otherwise just get an efficient car, preferably small. The PHEV worked for us in 2022 to be 3 vehicles in 1:

an electric city car
a safe, reasonably efficient country trip car (visiting family 250km away)
tow the camping trailer, small boat, or utility trailer up to 750kg In 2022, no EVs on sale in Australia could tow, officially. We are low car use people in the inner city. When not on our bicycles, 90% of our city km are electric & we once went 3 months without buying fuel - the car warned the fuel was old! The airport return trip in just in battery range. An ebike is also a very valued member of our transport stable. https://velectrix.com.au/product/cruiser-pulse-stx-step-through-cruiser-electric-bike/

@alexkidman Very good article about owning an EV. It's worth noting that petrol fires are dangerous, hard to put out & bad for the environment, which is why fire trucks carry special equipment & chemicals (foam) to extingiush it. Water works fine on normal fires & is a disaster on petrol ones. Petrol: it's not safe, It's just well established. We are noticing a 20% reduced charge capacity & range from our 8 year old Outlander PHEV. I think PHEV's work the battery a lot harder than EVs, because on a long trip it repeatedly gets as low as the system allows.

@robpumphrey@mastodonapp.uk Australian taxi drivers break the law when picking up & dropping off passengers all the time. Waymo are making common practice explicit. I'm not sure what the appropriate response is, because passengers want/need pick up & drop off & legal stopping places in CBDs are rare. Perhaps explicitly allowing a 60 second stop in a no stopping zone by a licenced taxi etc would be appropriate - sonething to give them somewhere legal to stop on every block, then enforce no double parking etc.

@tobeB Surely It's better for oil to be turned into plastics & eventually buried than for it to be burned for transport or energy? It's useful to have an alternative market for oil & gas that doesn’t just burn it, to avoid price drops leading to continued burning, although eventually that market will support new oil/gas fields. Burning plastics for energy does not help: It's higher CO2 per kWh than oil as well as emitting toxins.

@quixoticgeek@social.v.st But a 50w panel is not useful for domestic purposes. Check your power use. A panel in summers will give about 6 hours equivalent of full power, in winter a lot less. 50w gives about 300wh = 1/3 kwh. My household averages 420kwh/month = 14kwh/day so that panel is a tiny fraction of my use and worth 8c at our local daytime prices. Camping, 300wh at 12V is 300/12=25 Amp hours, which, with charging losses, will put about 20Ah into a battery - not enough for our camp fridge overnight (ignoring the need to power it during the day). My house has 6600W of solar panels, which gives enough in a Melbourne Australia summer (with air conditioning) but less than we use during the day on a cold cloudy winter day.

Last week on Wed 8th July there was a nasty power price spike in Victoria for an hour in the evening, averaging about %7/kwh for half an hour.
