It is indeed magical thinking. "$200,000 worth of Tesla batteries, which collectively weigh over 20,000 pounds, are needed to store the energy equivalent of one barrel of oil. A barrel of oil, meanwhile, weighs 300 pounds and can be stored in a $20 tank. Those are the realities of today’s lithium batteries. Even a 200% improvement in underlying battery economics and technology won’t close such a gap."
Meanwhile the battery industry currently uses 42 percent of global cobalt production, a critical metal for Lithium-ion cells. 70% comes from the Congo where kids do their bit against 'climate change'.

- mrob 8y agoCobalt is not a critical metal for all lithium-ion cells, only for maximum energy density lithium-ion cells. If you're willing to sacrifice energy density you can use lithium iron phosphate instead, which is also safer and more durable. BYD Auto, the Chinese company behind the great success of electric buses in China (preventing more CO2 emissions than electric cars) uses lithium iron phosphate.
