...dunkelfluate in that coal dependent hellhole Germany.
The Number of Tesla Powerwalls Required That Would Address the Current German Dunkleflaute Event.
...It is claimed they have a useable capacity of 13.5 kWh after being charged with 14 kWh of electricity, presumably at 25°C, with a putative thermodynamic efficiency - should you choose to believe it - of 96%. The maximum continuous power output is said to be 5 kW. The power requirements to match the combined coal and gas average continuous power of combined German coal and gas over the last 30 days, 44.4 GW would require 8,880,000 million Powerwalls®, to cover each day of Dunkelflaute; for 30 days, given that the wind wasn't blowing that much over that period, 266,400,000 Powerwalls®.
The specifications say that each Powerwall® weighs 114 kg, meaning that 30,369,600,000 kg of Powerwalls® would be required just for Germany.
According to Forbes, 15% of the weight of a Tesla Powerwall is cobalt, mined by Elon's happy Congolese slaves, meaning that the happy Congolese cobalt slaves would be required to mine and isolate 4,555,400 metric tons of cobalt to make Powerwalls® to cover this instance of Dunkleflaute with batteries.
This is 31.63 times as large as the world production of cobalt in 2021 according to the US Geological Survey
I'm sorry!!! I forgot to use "percent talk!" The demand for cobalt to cover month long Dunkleflaute in Germany observed in Nov-Dec 2022 would be 3163% the demand for all the world cobalt supply in 2021....
