Bloomberg posted an article about Elon's communication methods begin similar to Trump. Its paywalled, but the teaser does not mention that most times what Elon tweets is factually correct.

If I new it cud hlp with bad speling I wud take it!

Agree. The challenge is for the mad scientists CEO to know when to let the division CEO run the business, and when to order him to do something differet. IMHO Elon is pretty good at doing this, with just occasional head scratching action.

The beginning of the mass migration. Uber, Lyft Drivers Switch to Teslas as High Gas Prices Squeeze Profit (Bloomberg version) This raised my eyebrows. More exposure, more customers, faster migration to BEV.

You did great. Too many will take cyanide if doc prescribes. Another excellent is Jublia for toenail fungus. They want like $500 for a tube good for a week, but give them your personal info and its $20 per week/tube. Wiki on it here. There is a cheaper alternate, almost as good. But with...

All that is good, but does not mention youth mortality (probably does in book) Over 100 years ago YM was close to 50% , so humans needed at least 4 offspring for population to sustain itself. Today it needs to be slightly over 2, like 2.1. I agree with overall the indicator, but will take...

If you can afford it. My experience in taking care of family members, the expense, complicated system, and often sub-par service in USA is maddening.

In defense of that (while on fence myself), I did read that founding CEO's are generally great at starting companies, not so great at running them.

So far I talked with only 1 person who really knew what he was selling, and get answers I want. Research is not wasted, it is making up for sales people shortcomings that is wasted.

Yes, that is true. What I found is they provide a lot of detail on what you are getting, and an easy way to get a lot of quotes. You do not have to pick from them, look at the installers offers, learn about details. also free book "Solar Power Demystified".

I am doing same. Start here, check links esp PV Watts https://teslamotorsclub.com/tmc/threads/solar-system-info-resources-web-sites-personal-experience.267878 Then https://www.energysage.com/ and expand from there.

Here is ANOTHER car that claims to be able to be charged only by sun, and is about size of Model 3 https://lightyear.one/lightyear-0 5m2 solar cells and most efficient inverters This is interesting, motors in the hub Model 3 is over 5 year old design, and is largely based on a 12 year old...

I received some quotes National installer A Sys Size 6.15 kWp Est Ann prod 8000 kWh 15x Hanwa ML-G10+ 15x Enphase IQ8+ $18,656 National installer B Sys Size 5.95 kWp Est Ann prod 8050 kWh 14x Equinox M 425W 14x micro inverters $23,240 and the rest. Thoughts?

A remainder, if not aware. Not moving or anything, a Tesla consumes a bunch of watts. If sentry is on, or it gets too cold (can have sun on freezing days) the consumption is more. A PV roof will compensate, perhaps even recoup, all the idle losses.

Ah, the lesser used special purpose plugs.

Well, https://teslamotorsclub.com/tmc/forums/energy-environment-and-policy.36/ is too diluted with all manner of Energy, Environment, and Policy topics, wanted to focus on PV only.

US houses are 240V, so we good (YES on C2H / bi-directional)

Japan is 1 voltage (100V), and nearly same plugs as US (the 2 prong lacks the taller polarized plug, but if plug does not have it, works just fine).

Thanks. Probably changed from the book source, not notice

That alone kills hydrogen IMHO. Add to that you still need ICE, which we see in many respects is inferior to EV Just saying

BRILLIANT! What I have been saying is becoming reality! The simple idea a small shaft in tall buildings can be used as gravity energy storage. It does start with simple shafts, but does offer a more complicated system of individual blocks, but looks to be far better controlled than the nutty...

Looking to get Solar on house now. WARNING: needs a LOT of research and scrutiny to make sure it optimum!

In Europe, that IS long distance. It is often faster to walk across a city in Europe than use a car (while in Houston it is insane to even walk 1 block. :p)

So, the MSRP should be $34,772?? It is still theft, and a fool would pay anyone that much mark up. Then again, there are those with more $$$ than brain cells.

This is become an odyssey! FAR more than one would expect in deciding the system (it's not the panels and controller, it's everything else) And a good book is a must. Solar Power Your Home For Dummies and Solar Power Demystified The Beginners Guide To Solar Power Energy (at least this is free)...

A buddy of mine ordered his MY in September / October of 2021. A few weeks ago he was given a June 14~July 19 delivery window (it was later pushed back to July 14~19, then up to June 6~12). And yesterday, June 14, he received it! Amazingly the months old estimate was most accurate. production...

At least 2 months of good production (likely more), WTH are all those MY AWD SR (4680) going?? (Besides the few known to go to employees and company use). BTW, is factory producing on Sat/Sun?

Yes, that is what I am saying. There maybe be inefficiency and some added weight (could be small), the upside is build flexibility. Sandy talked about this in one of his videos and speculation on a Tesla web site (about 2~3 months ago). I would also guess this is a short term strategy as...

This is what I am thinking, a new battery box for Austin that does not use the battery to take part of the load. Modularity is a tradeoff of build efficiency vs build flexibility. From what I have seen and heard the battery box is self contained unit, and if not then very close to it. Fremont...

Exactly, but that is irrelevant to the car build itself.

No, do not think of "structural" or "non-structural" inside, think only of the box between the front and rear castings. It can be a fish tank for all I care, as long as it fulfils the structure requirements, then it does its job. Tesla cars are very modular, just plug in the desired module...

Agree. IMHO one reason for current slow production is insufficient 4680 production. As Mrbrock and others say, the production needs to significantly increase, by like a factor of 10

battery component is completely irreverent. The structure between front and rear castings is the issue, not what's inside them. All the "structural battery" does is pass SOME of the structural load to the batteries. Tesla will create 2 versions of the battery box, both will fit in same space...

Besides the purpose of those connectors, also miss the evolution (FYI: RJ11 and RJ45 are still in use for the same purpose, 60 years later, no change needed) When a protocol is improved, the hardware is also improved. Except that really did not happen with EV plugs. They took the J1772...

Sandy says Austin is a modular line, uses robot sleds, so is possible to even build a 2170 and 4680 at same time, alternating the battery. A PURE guess here is there is much work still going, so production is limited. Even the building is not 100% finished (at least still mounting PV's)

Only because Nissan and Mitsubishi failed to get sales for tis BEV, and Honda and especially Toyota failed to promote PHEV. Meanwhile the completely proprietary Tesla system is by far the most common. If Tesla maintains at least 50% of BEV market in US, then Tesla might just become a standard.

It is to replace all, with adapters for legacy. Did not stop USB from its everything USB-C connector.

Improvement, but maybe caught in politics?

Simple: 1 design of SC power supply and connector world wide, and be about same size as the Tesla (or possibly proposed Chao-Ji) connector. There is no technical issue preventing this. This will save tens of billions.

Exactly. The changes to charging equipment is rapidly evolving, the old hardware is already too limiting.

The "Target" stated in contract is: "...make sufficient voluntary prepayment(s) to reduce your total loan..." The loan "will re-amortize at the end of the 18th month", so there is an increase, and I am not sure if the % APR stays the same.

And yet we have a dozen versions of USB plugs and jacks. IOW, it will change, because inefficient and expensive to what it can be.

Anyone working on a unified connector?

The "subsidized $4k of the 6800", that was for the roof replacment? Was looking over the loan, and it turns out it is $90/mo for 18mo, then jumps to $122 for the remaining 18.5 years. Very disappointing. Also perturbed by lack of other details. I had survey done, will see what they say.

for everyone else who TL/DR Russian ICBM nukes will: A. most likely not get anywhere close to intended target, eg land on Russia instead. B. not explode, just splatter with radioactive junk C. contaminate Russia and cause massive wave of deadly cancer across Russia.

More than only poor quality, would you drive a 50 year old car? The T-72 tanks which is by far the most common tank in the war was put in production in 1968. 1968! Even the latest updates are still decades old. They are not just poor quality, they are obsolete. PS, the T-90 is a version of...

Thanks. The price looks high, but worth the extra? Thanks, will look though the 9 pages then.
