A WONDERFUL NIKOLA-TESLA RELATED STORY YOU NEVER HEARD 💜⚡️
My favorite professor during my undergraduate studies in Aerospace-Engineering was an extremely old Serbian gentleman who taught us 1st year Physics (Electricity).
He seemed a million years old. From another era. 1/
2/ 90% of the students enrolled to another professor - a young hotshot that wrote a textbook on the topic and taught how to pass the exam.
They said the oldtimer "wasted time telling stories".
My friend and I stayed with the old professor exactly for these stories.
3/ Example story:
One day he came to class wearing a sweater - pretty weird during springtime.
He stood with a mischievous smile on his face and told us since topic was static electricity, he came equipped for an experiment
He then rubbed film on his tummy, happy like a child
2/ (narrower separator - so foil edges would stick out to be folded with cap)
4. The devil is in the details, and so is the god. It's an out-of-the-box idea, which should be checked.
- If requires major changes, drop it.
- If moderate changes - HUGE HUGE gains there
3/ 5. "HUGE HUGE gains" are lower resistance (=more range, less cooling needed), plate cooling possible, faster charge and discharge, no tab-welding so faster production and less defected batteries
6. NOT suggesting changing size or going dry electrode. These require new line
We all wonder how Plaid can do back to back crazy-acceleration runs without overheating, while still using 18650s bc Tesla wouldn't throw away exiting line when batt constrained.
So here's a moonshot. What if exiting line was modified for tabless?
1/
2/ Mostly, you'd just need different capping and slightly narrower separator (so edges stick out for folding)
This enables utilizing legacy line while lowering resistance - greater range, less heating problem, faster discharging and charging
3/ THEORETICALLY (1st principles) it could be possible to move to plate heating (like 4680 pack) and ditch legacy cooling passages. This would enable crazy range if you want, lighter and cheaper pack. Batteries could be structural to some extent.
"Tesla benefits from a culture and ethos of what I would call “mad scientist thinking”: from the C-level to the interns, researchers and engineers are encouraged to explore ideas that sound crazy if they can convincingly argue for them on pure scientific and engineering grounds"
Interesting tidbit-
Kevin o'Leary thinks in future we'll start checking location that coins were mined, and discriminate against those mined with non-renewable. He calls China-mined as toxic.
@CathieDWood sees no inflation, only GOOD deflation.
