Tesla, TSLA & the Investment World: the Perpetual Investors' Roundtable

Got a jpeg screenshot of points a guy named Thomas made after test driving the EQC. Since in Norwegian I'll try to translate:
I belive this was the same car Bjørn Nyland has been driving recently. So the weird SOC display might have been just this car. Or maybe not.

Wait, so now we have two reports of that highly nonlinear SoC behavior?
That's starting to look increasingly like a cheat. There's no more obvious way to artificially inflate your car's range and efficiency than to hide all of the loss of range near the bottom of the discharge cycle and hope that people don't drain it down that far.
But it could just be a bug / defect.
ED: If it's the same car as Bjørn's, then it's too early to draw conclusions. Will be interesting to see.

Should read as "First Taycan goes on sale Sept 4th, next Taycan will be produced and sold Oct 4th.....and so on"

You could have written Toucan and we'd still know what you were talking about
And wasn't that exactly how some other tester did it, by extrapolating from a short trip? Rodent smell.
Yes, two reports - but probably the same car. As in Bjørn Nyland let Thomas try his car.

OT @kbM3: Formula 1, EVs and super capacitors.
After some more reading I will admit that when it comes Formula 1 there may be a point to super capacitors, but this is only because of how regulated F1 is.
One of the problems with capacitors is that while they have a high energy/weight density they have a poor energy/volume density. But F1 is regulated on things like power output, frame and weight, but not directly the volume. I don't do power train design, but I can see how doing something like using a gasoline motor to charge the capacitor and feeding the regulated electric motor might be effective. Such a design would use regenerative braking to increase the charge level of the super capacitor and might need to be able to increase gasoline motor output for long straights -- but being capped by the regulated motor output might obviate the need for that. The only reason to do this (versus a straight gas system using flywheels) would be overall system efficiency (I'm way out of date on flywheel based systems, but back in the day their efficiency wasn't that good). It might work out, it might not.
So, yeah, I'd forgotten how you can get silly artifacts from heavily regulated races.

And I suppose with hefty enough super capacitors you might be able to get an EV to compete in top fuel. Now that would be funny. Nor would it be allowed, even if you could somehow get electric motors powerful enough and enough high discharge mobile energy storage to run the race. The point of top fuel for many is the loud, abusive noise of the motors and the complete rebuild between runs. Can't take away their fun...
There's also the issue that with F1, cost is basically irrelevant, and every car is basically a prototype, and nothing needs to be practical as a road vehicle.
Regardless, the car to compete with top fuel dragsters will clearly be the Roadster with the SpaceX options package. If you want insane acceleration and noise....
The crazy thing is that if you wanted to, you could make the Roadster even more insane aftermarket by adding a self-pressurizing fuel tank (say, ethane) and replacing the nozzles with combustion chamber + nozzle arrangements, turning it into an ethane-air rocket engine for much higher thrust and/or longer-duration burns..

Expectations, hmm. Operational mistakes in European M3's "expansion" cannot be excluded either, possibly leading to departure of Jan Oehmicke, then Vice President of Tesla Europe, managing finance, sales and operations for the greater Europe region.

TSLA bump today probably attributed to our buying two Powerwalls

although $TSLA is mirroring macros it is outperforming them, just like it under performed previously.
My expectation is that the under performance was driving by shorting to exaggerate the macros and the slight outperform is the result of slow covering to minimize rebound. The shorts are taking profit to fund the next downward push.

If there's one thing I'm not worried about it's supercapacitors. Elon knows that *sugar* inside and out and is certainly on top of all developments.

Back on topic.....I just almost threw my back out. Tried to bend over and pick up a big chest and the right lower side of my back seized up.
Straightened myself okout and took 4 Advil. After 10 minutes was able to get onto my bed with no pain. Still mild tightness, but I feel like I could get up and walk around. Did I dodge a bullet?
Hydrating like crazy and letting the Advil take effect for 40 mins. Am I ok to get up if I feel just minimal tightness or should I just lock it down for the day?

I'm assuming this is a metaphor for the hopelessness of life.... and the TSLA price action of the last week?
I've been engaging deeply into Tesla solar and signed a contract Friday for 8.19 kW + 2 PWs.
This weekend, Tesla announced a solar rental program that appears to save folks money without many commitments or worries. It sounds like a good product (still better to buy Solar vs rent for best cost savings) but no advertising has me wondering why people would suddenly decide to get solar? The people on this forum all seem to have Tesla vehicles already. But all the others, how will they learn? (OK, so I just heard it on NPR this morning, so some news is getting out anyway).
Maybe this will catch on but time's running out for our Fed rebates. As I see it, we have just one year to get this right before the incentives drop off a cliff here in the US. But if it does take off, I think this will make Tesla the energy company we've been talking about because they will likely get 20+ years of revenue for free (after the first 7 yrs pay for itself). Why this hasn't happened yet is beyond me. The business model is similar to McDonalds where leasing land is the game. Here, Tesla is leasing the sun AND we're paying to have them use our roof. Very smart move.
FYI, there are some very interesting posts here by early adopters of solar and PW in Arizona if interested. Too much detail for this thread, but worthy of a stock catalyst mention here. Arizona Powerwall Installs
