Of course, in most states there is net metering, so it is foolish to store it; feed it to the grid. Storing in a battery will cost you about 15 cents/kWh and more like 30 cents/kWh with Tesla powerwall, so you need to have that large a difference between the cost of power when you store it and when you take it out. It is unusual to have a battery to store all your unused solar output, that would be very expensive. You don't want to store more than you will actually need, and in particular more than you need from 3pm to 9pm or whenever your local high-peak rate is. So it's up to you to measure how much you need then. (You will have solar from 3pm to 5pm or so, a bit later in high summer.)
If you seek home backup, generally you don't want to pay to run your home at full load during an outage. Surely in an outage you won't charge your car, or run your over or dryer, or your air conditioner on full etc. Consider how much power you need when conserving, unless you are expecting an apocalypse style outage. Get enough battery for that.
Few believed it would be pulled off, except the most devoted of Tesla fans. However, the point is they did promise unsupervised, which is the biggest milestone in this technology, and they didn't get there. It's like promising a moon landing and delivering a New Shepard suborbital flight. Yes, it's a safety driver. A safety driver is, in spite of the vocabulary, not expected to drive. They supervise and intervene.
It varies from country to country. 3 phase can let you send more power with the same copper, but it requires the connector be larger and with more pins, so there are arguments each way -- even in the countries where 3 phase is common. Most EVs don't come with onboard chargers bigger than 7-10kw, which can be readily done single phase, but is somewhat easier with 3 phase. But very little reason to use a 3-phase plug standard in North America. Only a few stations would provide it and almost no homes. Most people never charge at public level 2 stations.
Only the plug in North America is in question here. China has its own different plug too. In NA, 3 phase is uncommon. But for any AC plug, what matters is the rating of the car's internal charger. There are USA cars that take 18kw single phase, with Tesla's smaller connector.
No because when Tesla's system has a problem, as my car does a few times each trip, I grab the wheel. And waymo also has cars with safety drivers but also has run a million miles without one. Run Tesla FSD with no intervention for a million miles and it would have thousands of accidents. Thousands, where it was at fault. Waymo had 2 or 3 minor parking lot style no damage contacts in their million. Not thousands
If you read the press yesterday you would see that the large majority of articles took Tesla's report at face value, so it needed much more explaining than you imagine.
That's not correct, they are no more liable than carmakers are if you are using cruise control.
Unless you can show in court that their system was defective. It is designed to not be able to do the full driving task, to need interventions. It performs as designed.
Isn't that what I said? The logic above would work the same for cruise control. If you ship a bad cruise control or other automation system, you get sued and lose. Toyota paid out more than a billion dollars a few years back due to[1] problems with their fly-by-wire accelerator design. It's not like you can't punish an automaker for safety issues. They get sued all the time, successfully.
Except, notably, the one you want to yell about the most. I'm just saying that should maybe be part of your analysis.
Look. The cars are safe. We've been having the same argument, again and again, for years and years now. People show up in these threads just taking as a given that these systems are unsafe, and refuse to adjust that prior as these cars become some of the most popular products as a market.
[1] What were perceived as -- IIRC it's since been argued that the problem in the suit didn't actually exist. And they settled anyway!
Forbes pays contributors, who do so by invitation by a Forbes editor who likes their writing. Forbes also allows companies to pay to put in stories, but they are clearly marked as such.
It's amazing what people will write by assumption without knowing.
And yes I believe in the value of the technology. But also in the truth which is why I was very harsh on cruise in the story earlier this week.
The problem is the bus front was occluded and thus its position and vector were estimates of growing uncertainty, not direct readings. It is not understandable that an estimate with high uncertainty took precedent over a fully reliable direct reading from multiple sensors
