Amazing ...correct (or rather they are subject to your evil, dysfunctional money as debt system, enforced by the IMF down: IMF = "Instant Misery Fund").

This is what revolution looks like, you better get used to it, it's only going to increase as inequality continues to soar and capitalist pollution threatens the planet's ecology, in your evil money as debt system, regardless of the veracity of AGW-caused by CO2 emissions - veracity which you deny, thereby displaying  the worst type of fundamentalist ISIS behavior.

That's right - not fundamentalist; unlike you being  absurdly assured in your rejection of climate science.

I see that a large number of climate scientists have presented a compelling case for large numbers of people who see a connection between climate catastrophes and man-made CO2 emissions, and I am certainly not prepared to reject the science, as you are.

Hence I'm agnostic...and open to "conversion". 

But I am certain global capital serves its own profit- seeking purposes,  rather than investment in poverty reduction and sustainable prosperity.

Indeed I'm agnostic on AGW CO2 climate change (and open to "conversion" on the science, unlike you), but I'm fundamentalist on poverty eradication.

Dunno...but more importantly, which part of global poverty (eg dung-burning Indians, tree-clearing Brazilians engaged in subsistence agriculture) are you insisting must remain, to threaten community and environmental  health and sustainability?

On the need to manage global capital for sustainable prosperity, for a habitable planet; impossible with pollution and environment-destruction associated with wide-spread poverty.

Er... sunshine and wind are free, and their harvesting, via rapidly expanding renewables technologies, is proceeding apace.

No. I'm the one taking the BIS at its word: "central banks might have to buy the fossil industry" (and fund the transition  to green economy).

And as compensation for crimes of past colonialism, Africa and India (and developing nations)  should have the technology handed to them.

I haven't read the article, but obviously the problems weren't solved because global capital went missing as usual, being interested only in places where it can profit   from its own investment.

Well if the Donner Party be our guide they will be eating each other in a matter of days.

The Chinese have also built a railway to Mongolia to access large deposits there.

What? Pay for storage for that power supplied free from the sun  and the wind?

Please tell us one battery backup that can provide say 5 days overcast and no wind.

A  ;lot of wishful thinking there.

"Storage duration: longer storage durations than equivalent li-ion batteries (3-10 hours vs 2-4 hours in li-ion batteries) are suited to provide energy from renewable sources when the sun is not shining, and the wind is not blowing."

So to last 5 days you would need somewhere north of 12 in parallel to get the hours multiplied by an uncertain number in series to get the voltage.

Ah pumped hydro with its own limitations.

thegreatdivide wrote on May 3^rd, 2022 at 7:29pm:


"When Snowy 2.0 generates electricity, water will be released from Dam 1 at the top of the system. It will flow through a long tunnel to the smaller Dam 2. The flow of water drives turbines which generate energy. When the turbines are reversed, the water is pumped back to the top to continue the cycle.

For Snowy 2.0 to produce the 350 GWh of electricity claimed, the top dam must be full and all that water released through the system. But replenishing the top dam after this event would take many months of pumping water from elsewhere in the system, and use up 40% more electricity than was originally generated. So the 350 GWh would never be achieved because it is extremely inefficient and inflexible.

In reality, the pumped hydro capacity of Snowy 2.0 is defined by the amount of water that the smaller Dam 2 can hold. If the scheme was a closed system, with no other water flowing in or out, it could produce around 230 gigawatt hours (GWh) of electricity.

But the system does not exist in isolation. Part of the existing Snowy Hydro scheme, known as Tumut 3, also uses Dam 2. It creates pumped hydro electricity by cycling water between that dam and the even smaller Dam 3 below it.

For Snowy 2.0 to operate at full cyclical capacity, Dam 2 must be empty to receive the water. That would entail emptying Dam 2 into the smaller Dam 3 and from there to Dam 4 at the bottom of the system. This water could not be used again to generate electricity. This “lost” water would have generated 60 GWh worth of electricity in the Tumut 3 scheme."

Just another one of those engineering challenges.
