@ajsadauskas @SituationCake @Seagoon if they could bottle the rage that “self service” checkouts produce they could power a city the size of Melbourne for a century.

@ajsadauskas @popheads radar-like navigation system? That would mean they did not fly at night before 1940, as radar hadn’t been invented yet.

@veronica @ajsadauskas @technology The hype around AI in software engineering seems to be that it is ‘proven’ that devs produce code quicker. it is going to be interesting to see if the corporate world values code quality over development velocity. There seems to be a pervasive belief that “move fast and break things” is how the big guys do software engineering. A few points to note:

1. this idiom only applies when you fail fast, realize it, and address the problem that has been introduced.
2. Break things does not mean enshittify ie create tech debt by virtue of poor code
3. It really only applies if you have enough development resources to do the rework. That is to say, can afford to get it wrong often.

@Wiggles good pick up. I was out by a factor of 1000. I should have double checked. But even if is not so compelling, it's still a technology that has the possibility to make a huge impact. EV storage is only going to increase.
There are V2G chargers on the market now, but it's illegal to connect them to your home outside SA.
There should be no impediment, particularly when state governments start talking about relying on home storage for grid stabilization.

@Wiggles Australian electricity use in 2020 was 265,232 GWH for the year. That's 726 GWh / day. If we take 12 h of daylight, during which time solar generation is providing power, (and recharging batteries), we can say we need 1/2 the daily amount for overnight storage, or 363 GWH.
If we say each ev has 60kWH of storage, that means we need 6050 cars, or 18150 cars if we only use 1/3 of the battery charge.
There are 20,000,000 cars in Australia (20 million). That's enough to cater for Australian daily energy storage needs 1100 times over, assuming a conservative 1/3 of the stored energy capacity is used.
So I dispute your conclusion that here has to be v2g charging points every where.
As per the above, if only 1 in 1100 cars (lt;0.1%) had a V2G connection at home, that would provide enough for Australian energy storage self sufficiency
Its a fucking no brainer. So why is south Australia the only state that allows V2G connections to the grid?

@Wiggles if they are going to rely on consumer storage, the state governments of Australia should really pull their fingers out with V2G technology. An EV typically has at least 3x the storage of a fixed home battery, 60kWH vs 20kWH. So if they really want consumer storage to work, it needs to be accessible. At the moment South Australia is the only state where V2G technology is certified for connecting to the grid. #V2G

@ajsadauskas @fuckcars @australia I agree. It's really disappointing. About a month or so ago, the reason it wasn't going ahead was due to a break down in negatiations with the airport, over whether or not the airport station would be above ground. Reading between the lines it would seem the airport has got it's way and the state government has had to go back to the federal government for more money to build the rail line underground.
