Road transport electrification presents a once in a century opportunity to address the user-pays element (currently petrol/ diesel tax) that contributes about half of the direct costs of road spending (including maintenance, administration, expansion, enforcement)

Coogee: presumably because MSM has been complicit in promoting and editorialising the “shark nets don’t work” narrative, they are notably quiet on observing that, after a spate of early C20th attacks, nets prevented any attack from c1937 onwards. Nets removed, attack occurs

But of course, for the MSM there is no plausible link between the removal of shark nets they supported and a shark attack, instead multiple mentions of “climate change”

The sheer scale of a trillion dollars can be hard to comprehend. Let me put it in perspective. You would be able to buy 42 miles of high speed rail in California with that much money.

my view on the removal of shark deterrent nets was and remains they are worth the collateral damage on the precautionary principle alone. today’s events only reinforce that, and really bring into question Randwick Council’s decision (and alternative mitigations) at Coogee
Replying to @roodave
(or swim in a fully netted/ enclosed pool, like Watsons Bay, Nielsens Park, Redleaf, Clifton Gardens etc). Just insane the NSW govt was (is?) adopting advice to remove deterrent nets from surf beaches, just sick misanthropic behaviour

Community Halls often interesting social history reminders/ contrasts with present day. From 2001, a patchwork quilt celebrating community themes for renovation of Mosman Scot’s Church hall: Scouts, Guides, military, Jesus, beaches, Scotland, Old Testament

Reminds of the Watsons Bay Public School, symbolism that is probably incomprehensible to school (and uni) leavers today x.com/roodave/status/1621641…

Frozen in time as it was in the early 1990s when I was a cub and scout. 1st Vaucluse Scouts mural. Also where my grandmother started school in 1920s, the former Watsons Bay public. Now where we have the kids birthdays, courtesy @woollahramc

Today, if there was any civic institution as scout/ church/ community halls were c2000, the front door “Promise” to God and the Queen would be replaced with a land acknowledgment, St Patrick’s cross with an aboriginal flag, a scout slaying a dragon with a dot painting

I am neither a big fan of Sydney winters nor traffic on Military Rd Mosman, but the extraordinary beauty, outlooks and afternoon winter’s light from the Bradley’s Head walk (amongst others) makes up for it

Also worth reflecting on the decision making that gave rise to existence of these beautiful walks and reserves: late 1990s/ early 00s community movement that today would be described as NIMBYs lobbying against Cth govt naval land sales to developers (formed Habour Trust instead)

having been close to the process (as I guess the youngest member of the trust’s consultation committee c1999), it is interesting to contrast the contemporary reaction to flogging Victoria barracks etc. A seismic, perhaps overshoot towards, or Machiavellian use of YIMBY narrative

Anyone aware of any analysis or explanation of what is going on here? This is very unusual. Passive “piston effect” ventilation is the norm in most metros. Fans mainly for heat or smoke. Tunnel temp usually higher (no condensate). Possibly water ingress to tunnel and cavern?
So evidently they built the Eglinton Crosstown (Line 5) without a forced air circulation system, relying on “passive air circulation”. This results in sopping wet platforms on humid days, all in the name of “saving some energy”. Crazy design decision @Metrolinx.

What sort of Australia are we building? What are we trying to incentivise? What do we want our country to look like in 10, 20, 30 years time?

The biggest problem with linkedin is that it is associated with one’s corporate/ employer identity, not one’s individual personal identity, basically creating an “on message” loop of individuals reinforcing what ever they perceive to be the institutional positions/ directions

New America’s Cup-inspired hydrofoiling technology for small Sydney Harbour ferries you say? (Photo: PJ&MSSCo circular quay- Manly hydrofoil, “Manly” in 1966 JRCaldwell)

Electric ones a cool concept, will be interesting to see how it goes, but getting 30 people and a boat with a big battery to hydrofoil takes quite a bit of energy, not easy, lots of charging. Tough for productivity on busy summer days unless you have specialised fast charge infra

But seriously how can you write an article on introducing hydrofoils to Sydney harbour without noting there were regular commuter hydrofoils for 25 years
