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
4/ Another story (next one will be Tesla😋) was that when he was 5yo he had his 1st experiment with electricity:
He stuck a nail into the socket and learned that electricity is dangerous
He also learned something unique to him- why his entire block was in blackout for 3 days😂
5/ He also told us how when he was a student, they collected funds several times, to pass money to their compatriot Nikola Tesla, who was pennyless abroad
He said Tesla's name with awe, used his inventions in several topics we learned, taught us a lot about him and swept us all.
6/ Exam that year was different, and we had to THINK.
But we knew how to tackle the subject, so I scored 100 and so did my friend
Most of our group scored higher than those studying with the hotshot equations guy
7/ Several years later I still visited him whenever work brought me to the U
Mostly we talked engineering and physics. He was older than the moon but as curious as a child
8/ Last time I saw him he told me he doesn't actively teach anymore, "the students say he tells stories instead of teaching"
Tha fools.
I told him "They just want to pass the exam for that semester. You taught us to love science, so we can pass exams all our life"
9/ It was true - he taught us that physics is FUN, and that the key to ace it is to keep curious, to always search for the hows and whys
This had a huge impact on my engineering career ever since
--
A couple of years later he passed away.
I will never forget this wonderful man💜
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.

HELP NEEDED!
I need your help for a video I'm making.
Do you recall a movie scene (or music vid, cartoon etc) where ppl
turn light on and find something huge/surprising/frightening/important
OR see one thing and then something else big hidden behind it or in plain sight?
1/..
2/ My video is on a hot topic and shows something people didn't notice, probably bc other things drew their attention, so it's either I turn the light on this topic (and show what was in dark) or i show something people didn't see bc focused on something else.
..
3/
Any help would be appreciated so there will be a shoutout to anyone that helps.
Even if you don't find something, just ask clarification questions - i'll mention you (unless you ask not to) so please think for a moment whether you recall such a scene.
Thanks guys!
