Perth time == Singapore time. I bet you're use to living on the east coast.
Central timezone, actually. Perth is not part of the NEM, and pretty sure the plan for this is coming out of the Northern Territory

Is it? That's the thing we literally mass produce in factories. I think it's the machinery to do voltage conversions and transmission that is the critical cost factor.
From a competitive point of view, yes. The conversion hardware is common in both cases, the difference is one side needs more storage than the other. As others have stated, with the propagation of EV voltage conversion equipment, that's essentially mass manufactured too now.
Edit: I'd also like to add that for something cheap and mass manufactured that we shouldn't concern ourselves with, we sure don't have a lot of it on a grid that already delivers some of the most expensive power in the world. ie one that should be able to afford it a lot more than others
I think any project is going to need some form of capacitor as a grid would just become unstable if you dump a huge amount of peak solar onto it without the consumption.
So either way you need batteries, and all the problems they bring. Just about "how many".
Sure, but that how many is a critical factor in the overall cost of energy delivered
There are batteries included as part of this project. So I don't think time really matters.
Yes, but will it wipe out the advantage of solar by adding cost to the generation capacity? As I said, batteries still aren't cheap, and their replacement lifetime is still not good. We could rely on future technology, but is that a sound investment plan?
If this project is viable, then it'll probably be more viable to have a massive solar farm coming from India, where the timezone shift is in the correct direction, and it would outcompete Australia.
I keep seeing stuff about the viability of the cable being laid. The thing that gets me though, is the timezone shift around peak solar generation is the wrong way around. In Australia at least, peak demand is in the evening, when people get home and turn on their ACs, or cooking devices etc. I don't know about the demand patterns in Singapore, but given their heavy use of AC, I imagine their demand for power does not peter off in the evening much.
Meanwhile the peak of solar generation around midday in Australia is being sent off to Singapore in the morning who are a couple hours behind us. Presumably the morning is when the least AC will be used there. By the evening in Singapore, it'll be night in Central Australia, meaning there will still have to be plenty of peaking generation or, will need a massive ton of batteries which has still not quite there for grid scaling.
This is an article pumping information control legislation from an organization who receives at least 47% of their funding from the department of defense, Lockheed Martin, BAE Systems, Northrop Grumman, Thales Group, and Raytheon Technologies. This article itself seems like an "information operation", in the article's parlance, to help generate consent for legislation that controls information.
There is practically no empirical evidence in this article, just reliance on vague "indicators" and the time of tweets. Forgive me for taking this with a massive grain of salt.
We've already got Identify and Disrupt, what do they want next?

Note that he says estimate of human survival. It could well be lower. Also some people are going to have lower thresholds than others.

The premise is contingent that all mosquitoes are bad. Turns out there are non blood sucking mosquitos that are eaten by other things, as explained in the article. So basically: blood suckers, yes, other mosquitoes no.

What people definitely don't give enough importance is CO2 buildup as well. The more isolated a place is, and smaller, the more environment friendly it is BUT the more likely it is to build up CO2, which leads to headaches.
I installed a CO2 meter both at my current home, and at my parent's home for when I go back for Christmas. In my home, it's a fairly big open place so it takes ~2 days of closed windows (0-3C outside) to reach 2000PPM (recommended under 1000, above 2000 starts affecting you, 5000 is the legal limit[1]). However, at my family home where I grew up it's a tiny room and it reaches 3000-4000 just by sleeping there with the window and door closed. So the headaches of "visiting family" might in big part be explained by this.
PS, incidentally in Spain!

These are starting to catch on, as someone else said Heat Exchanger, but that's a more general concept and this is the thing you'd actually want https://en.wikipedia.org/wiki/Energy_recovery_ventilation

Would definitely be interested to hear how he got in this mental state. It's a matter of frustrating and predictable reality that people who are poor and non-influential easily end up in a suicidal spiral. The same cannot be easily said of CEOs, especially ones who work for the public good, particularly combined with reformative policy and a progressive attitude to the workforce. I can't help but think there is significance in his choice to commit suicide by means of the thing he managed.
