"Surround video. More cameras simultaneously, seeing how images change over time. Labelling that. Sophistication of the neural net in the car is changing dramatically.

"This time is not like the past.
It's time we take action.
Running this type of experiment is insane.
Might as well move to the future" #Tesla#BatteryDay@elonmusk
"In the past 10 years, power production in coal went form 46% in 2010 to 23% in 2020" #Tesla#BatteryDay
"To achieve the transition to sustainable energy, we must produce more affordable EVs and Energy Storage, while building factories faster and with far less investment" #Tesla#BatteryDay $TSLA

"Money is an ethereal thing. Depending on how efficient effort is, we want the most [produced] batteries." $TSLA #Tesla#BatteryDay

"Early growth was promising, but growth is plateauing. That's what's motivating us."

BATTERY DIAGRAMS INCOMING:
"Bigger Cylindrical Cells Cost Less"
"... it isn't just about creating a bigger form factor"
"You need a stable structure to contain the ions. Can't crumble, or get gooey -- needs to hold its shape. As the ions move back and forth, it needs to retain its structure.... or [suffer] reduced battery life."
"Largest casting machine that has ever been made, which is casting right now at our #Fremont plant. The entire rear section of the car is a single piece of high pressure cast Aluminum."
"The non-cell portion of the vehicle has negative mass."
"Allows us to pack the cells more densely. We have no intermediate structures. The pack itself is structural."
"The filler is a structural adhesive, which is also flame-retardant."
"If this was in a convertible with no upper structure, that convertible would be stiffer than a regular car."
"You want to transfer the load into the structural battery pack without arbitrary loads on the battery. You want to feather it out... cells closer to the center.." $TSLA
