@flcnhvy @WholeMarsBlog @truth_tesla @LimitingThe This is obv debatable, but I’d call anything with ~300 miles / ~500 km of true usable travel distance “long range”, beyond that “very long range”

@WholeMarsBlog @truth_tesla @LimitingThe There are vast amounts of iron (and lithium) on Earth, but much less nickel. For global industry to scale battery production to ~10 TWh/year, it needs to be mostly iron. Higher energy density of Nickel only needed for very long range vehicles & aircraft.

@truth_tesla @LimitingThe Our new cell is 46mm diameter with steel shell & even that was huge challenge for propagation resistance

@truth_tesla @LimitingThe Yes. Physics of large cells means distance from cooling loop to center of cell is high, so harder to prevent hotspots. Then, pressure & heat released from large cell in weak bag make it impossible to stop whole pack from burning. Pretty basic.

Time is the ultimate currency

@long_elon @LimitingThe Iron, the last element made in a star, appears likely to exceed nickel by 3:1 or more

@LimitingThe Generally agree, but probability of thermal runaway is dangerously high with large pouch cells. Tesla strongly recommends against their use.

@teslaownersSV And Beta 10 is a step change improvement from what you have!
