Tesla Model 3

[sendler]

Battery packs are the last thing I would have expected Tesla to be having trouble with since they have been doing this by the 100,000's already for the Model S.

Not so much. If there is no place to store them.......

According to 1 news outlet Tesla has found a creative solution for low production numbers...

There was a stop-motion animation done as a side project by Disney artists in the 1960s. Live action with 6-8 actors. I can't find it online, can anyone?

...saw it in an officer's club on Long Binh post. The girls ran around with their hands out making motor noises and laughing for 5-10 minutes.

Slightly older, but interesting article on how the Model 3 battery differs from the Model S (with lots of nice pictures).

The most interesting thing to me: they did away with the separate battery heater and use the motor inverter to lock up the motor and produce no torque, but heat and the liquid cooling/heating circuit is heated by this effect.

Thanks. Now I won't need to read it.

For lack of a better place to post: The Roadster is on route to Mars. They had a dashcam looking over the driver's shoulder, through the windshield, into space.

My favorite moment was the synchronized propulsive landing of the boosters a quarter-mile apart.

An article about robotic production at Tesla. "It's a glimpse into Musk's plans for factories of the future: almost fully automated, with robots that can build cars so fast that air resistance becomes a problem.":
Tesla employee explains why production hell is actually a good thing - Business Insider

If Musk and Tesla succeed in this reimagining of the car factory, it will be the first new major innovation in manufacturing since Toyota created the famed Toyota Production System in the 1970s and 1980s. And it would add a level of irony if it were to happen at Tesla's Fremont factory, which was once jointly owned by Toyota and GM so that GM could learn the now vaunted "Toyota way."

Also that propulsive landing was 1/2 second out of synch to prevent radar cross-talk. Which makes it even more impressive in my opinion.

The Horsepower Hour EV to ICE Comparison
One Horsepower = 746 Watts
One Horsepower Hour = 746 Watt hours
One Gallon of Gasoline = 111,836 BTU/3412 BTU per kWh = 32.777 kWh
One Gallon of Gasoline equivalent is 32.777 kWh for EV purposes.
Thence 32,777 Watt hours/ 746 Watt hours = 43.936 Horsepower hours.
Rounded up to 44 HP hours are in one gallon of gas or gas equivalent.
