Cameras make fake shutter noises. Why?I'll look into it to see what "sound generator" really is about but the idea of generating sounds just for the heck of it sounds ridiculous to me. If it's for nostalgia, I'm out. Otherwise, then why not also for toasters, chimneys and ball caps. SMH. Just carry a smartphone and speaker. Anyway, I'll look at the video later.
Some interesting facts I found. Australia uses 229 billion kwh per day. This battery is 1.68 billion kwh. So this battery will be able to supply 10minutes of Australia's daily energy usage if fully discharged for 25 million people.
Reading the article linked, it says that the Waratah super battery is the first item to be funded under the $1B fund. It's not clear how much of that billion is committed to the battery project. Also, a billion Australian dollars is only around $670M US.
Like a button click, it tells me my action was entered. It doesn't have to be loud because I don't need to tell the world about my camera. Imagine how ridiculous it would be if they made computer keyboards as loud as typewriters. In an EV, a speedometer can signal everything noise could. (natural noise can help with a manual transmission but those are obsolete in many cases). EVs generate noise below 25 mph or so because that's when there might be people around who want a warning.Cameras make fake shutter noises. Why?
You will need those peaker plants anyways because South Wales has > 2 cloudy days in a row where solar PV output will be at 10-25% nominal about 15.5 days a year statistically. So the battery capex is not in-place of the peaker plants, it will be in addition to. Or have frequent blackouts along with high energy costs.Reading the article linked, it says that the Waratah super battery is the first item to be funded under the $1B fund.

To answer your question, 100 MW of installed gas turbines cost $123M US (capital, not including O&M). The battery is rated at 850 MW, so an equivalent output would cost around $1B US. To me, the battery itself is a surprisingly inexpensive replacement for natural gas peaker plants.
Your ancestors must have just been an absolute party in roughly 1905. "Those durn horseless carriages will never replace buggies. Why they're too expensive! And there's no place to buy fuel! They're only a toy for the rich! By gum these newfangled E-leck-trick lights will kill us all! Give me a good old gas lamp any day! And doggone it, the nightsoil collectors were good enough for my grandpappy, so they're good enough for me! Indoor plumbing is impossibly expensive and unsanitary to boot!"You will need those peaker plants anyways because South Wales has > 2 cloudy days in a row where solar PV output will be at 10-25% nominal about 15.5 days a year statistically.

With or without the sunk cost of a hundred years of pipeline right of way acquisition?
Ah playing the buggy whip card. Also what find interesting is that this comically expensive project which will consume resources and undoubtedly raise energy costs for Australians will have a negligible reduction in CO2 emissions, from a country who is the largest coal exporter in the world.I'm pretty sure that nobody has said that the entire NSW energy grid would be supplied by solar. There are other renewable technologies, some of which work in the dark or during storms. You might have heard of them.
Obviously, you know the entire system backwards and forwards. Therefore, please enlighten us as to:Ah playing the buggy whip card. Also what find interesting is that this comically expensive project which will consume resources and undoubtedly raise energy costs for Australians will have a negligible reduction in CO2 emissions, from a country who is the largest coal exporter in the world.
The Muhmorah coal plant used 3.8M tons per coal per year. Australia exports about 500M tons of coal per year. If the Australian government was serious about reducing CO2 emissions they would simply start shutting down their mines. CO2 emissions would suddenly drop and coal prices would skyrocket forcing the world to move to less emitting (more expensive) power generation. The CO2 reduction of this project is in the noise compared to the CO2 emissions Australia is enabling.
Perhaps the European protester who glue themselves to things should focus on the politicians down-under?
I'm sure that the reporter is keenly aware of COVID and chip shortages. I think that the "three years late" thing is really just the difference in culture between the automotive industry and the aerospace industry. It's totally reasonable for aerospace projects to be 3 years late, so that usually ends up way down in the article. It's a lot less common for automotive projects* to be that late for the first unit, regardless of causes. My impression is that most automotive manufacturers deal with time crunches by still releasing the first unit on time or close to it, but having very limited availability until the supply chain resolves itself. Given that, it's not too surprising that an automotive reporter would be a little saltier about the first unit being late.Nice "... three years late" headline . An automotive reporter that wasn't aware of COVID and issues in battery and chip supply chains? And implying the 3-year delay was due to the manufacturer? . Seems like talkers and watcher just have to find some kind of negative against doers, even at the risk of sounding uninformed. Maybe they're indegenous so I'd rather go easy on them.
I am not against renewable energy. Actually I am a big fan because it will extend the life of remaining essential fossil fuels hopefully long enough that we start deploying nuclear plants before we run out.Possibly. I have very little sympathy for naysayers and those who sound like or remind me of naysayers.
I am not hurling criticism, just presenting a realistic counterpoint calcs and facts that just demonstrate how difficult this endeavor will be to succeed.Thanks for participating. Every now and then I hope you'll try to participate constructively rather than just hurl criticism at those trying to solve problems.
But apparently today won't be the day?
The really frustrating thing is that whenever anyone presents facts and data to you, you either blow them off with a "far too expensive, can't ever work, and renewables suck" response or you just go silent and apparently pretend it never happened. Every. Single. Time. So it's not surprising that people go to the ad hominem. You've shown that there's no point in trying reason except for pleasing one's better angels.I am not hurling criticism, just presenting a realistic counterpoint calcs and facts that just demonstrate how difficult this endeavor will be to succeed.
Every now and then I hope you will present your counterpoint with facts and data (not hopes and dreams) instead of ad-hominem attacks against those who you disagree.
HVDC transmission lines have a lot of advantages for long distance transmission. Namely you do not need lossy capacitors in the chain to prevent ground potential differences over long distances from frying the transformers. At the terminus of the line is it converted to old fashion MV AC so there would be no EV charger benefit.Here's an interesting article about the need to start planning now the charging network for EVs. The chargers are not the biggest obstacle, the transmission lines are.
In the Solar thread I posted about a HVDC line being built in NY to transport power from Quebec to NYC. (I didn't even know that HVDC transmission lines existed.) Since these big charging stations are HVDC then building HVDC transmission lines to power them make a lot of sense. Note that if you link on the link below a diagram you can download the White Paper.
A new report warns that EV charging along Northeast highways will require sports-stadium levels of grid power by 2030. Where are the plans to supply it?www.canarymedia.com
Interesting article. And if anyone is suddenly interested in how elements of the periodic table are produced, refined, traded and used, I'll happily start a new thread for each one. Fascinating stuff.
That's interesting. As you say, not cheap, but does open up more choices for Level 1 and 2 charging for non-Teslas.
