Who are you speaking with on Norfolk Island?

Scarcity of quality weather observation data is a global issue.
Forecasting is cheap. Observations are not, but shared freely for global modeling.

That is Altocumulus cloud. Very pretty.

No, you assume that VFB will not enjoy the same volume production cost curve that lithium had. Also, lithium is far more valuable in other applications.

Flow batteries, or the go-to lithium?
One is the future, the other is the past.

Another possibility on such an old airframe is control surface failure....
Very unpleasant.

Hopefully encourages more Australians to vote for Independents.

I think you mean spatial disorientation. But short of a failed gyro, a competent IFR crew would fly the instruments, not the ear.
Still possible of course. Maybe pilot flying had an inopportune heart attack? Pilot not flying is there for that though.
Weight and balance issue? Maybe.

In Perth we are lucky that we can just run evaporative ac most of the summer. The cost is close to zero after installation.

Yes, a close second benefit is that 95% of my EV energy comes only from the solar panels at home.

Can we please, please get trending topics for Australians?
Please 🙏🏽
Xitter has it, which doesn't help because the place is a toxic hellhole. But all we many, many Australians here on Bluesky see is American stuff - we have our own topics

I think the 3.14 is missing from the start of neapple.

I believe it was around 1GWh, but announced or in-construction VFB projects are magnitudes greater than that over the next few years.
Lithium is great for meeting power requirements. VFB is superior for meeting larger energy requirements.

Probably partly the Musk effect. But increasingly viable alternatives becoming part of the Australian market likely influencing Tesla sales too.

False. VFB compete on every genuine metric for longer duration (6hrs+) over lifetime LCOE.
Show me otherwise.

I am genuinely surprised that you are not across this Simon. Even as a billionaire, I thought you more intrperested in outcomes in the interests of all mankind than the Elmos of this world, even plebs like me. This is a major energy policy issue.

Vanadium flow batteries are already the technology of choice for deep storage on the electricity grid China, and China are now the World leaders in modern electrical grids and renewables and storage. China are building more #VFB storage than than the rest of the world combined.

Vanadium flow does this very well, for 10's of thousands of cycles - the vanadium/sulphuric acid electrolyte life cycle is almost indefinite. It is only the power unit membrane stacks and associated pumps/piping that need replacing after 20 to 30 years. this makes VFB technology very sustainable.

Vanadium flow battery storage technology is much more economic for 6+ hours of storage and energy arbitrage on our grids in the future few years.
Lithium does not do 100% to 0% well at all, nor constant deep cycling without degradation.

(disclosure, I own an EV and lithium batteries are the best and most economic tech for EVs for the foreseeable future).
Large lithium storage is also good at up to 4 hours storage for on electrical grid stability.
comment in response to

Lithium also has a huge apparent cost advantage right now with volume of production - lithium has low unit power costs, power being the only focus in most Western press releases because because of the EV volume production and immediate needs of the electrical grid
comment in response to
post
Politicians like announcements and you can get an announcement out with every new big lithium battery built every ten years because they do degrade and need to be replaced. How convenient.

Flow batteries haven't been able to compete in Western markets to date for a few very simple reasons, especially in the case of vanadium flow batteries (invented in Australia 40 years ago).
Billionere "Elmo" is a big factor. Long duration is another, now changing in leading markets like China.

The atmospheric adiabatic lapse rates are rarely that stable. I think you are taking the piss 🤣

Only number that matters there is dewpoint. 22 is definitely starting to get uncomfortable.
Dewpoint of 24 requires lots of fluids to be drunk, and is very uncomfortable if you have any physical exertion.
Dewpoint over 28 is fatal over any length of time without intervention, like climate change.
