You sure about that? That would mean either running an electric oven, or an electric hob, or an aircon. But no more than one of those at once.

It's 230 V so two of those but not all three indeed. I don't have an electric hob but electric heater + dishwasher + oven certainly triggers the breaker.

If I'm getting what you're saying you have 15amp service for the house?

My house was built in 1950's. Used to have two 20amp fuses. One for the lights and one for the outlets.

In the US houses typically have 100-200 amp service now.

Aren't solar-cells on the car like multiple magnitudes less power than regular level 2 chargers? There was a lot of talk about why Tesla wasn't putting solar panels on the cars when the Model S was still new, and I thought the general consensus was it would need crazy amounts of time in direct sunlight to even make any kind of significant impact on the charge. I mean just look at this announcement. They are talking a…

And that is why I did write "Is probably not doable with current technology, but maybe some day". We need to have much more efficient solar-cells to make this work in real life. But is it more unrealistic than getting charged from the road while driving? One step on the way is getting them enough efficient to charge the car while it is parked outside at work

You'd have to make the surface area of the car a thousand times larger than it currently is. Or, if you could make your solar panels 100% efficient, it would only need to be 200 times larger.

You don't want a "car" that big.

I can't wait for the wireless charger that lives up to the name "Tesla".

People might find it slightly inconvenient when their keys get torn from their pants and watches ripped from their wrists every time they charge their car.

Tesla used electric fields, not magnetic ones, for his wireless power tests..

Yeah, this is closing the gap in a significant way. It's still not "charge on the way to work" fast, but it wouldn't be a painful delay on the way home. More important, it's an improvement . I still switch back and forth between my Model S and an ICE car--I can't remember a time when the gas station experience ever got better .

The difference between 90 seconds to fill up and 3 minutes to fill up is negligible. The appetite for improvement isn't there because the marginal is small. The difference between 3 minutes and 20 minutes is still enormous . Pretending for a minute that superchargers were as common as petrol stations, that there were never queues and you always started charging immediately. I would still not consider that a reasonabl…

It also depends on where and how you drive, park etc.

To me, the difference between filling up on gas and 20 minutes on a Supercharger not only isn't enormous, but literally doesn't matter. But that's because I charge at home, usually drive only around the city and when I go on a trip where I need to supercharge, it's a few hours between chargers and by that time I need to take a ~20 mins break for coffee anyway.

If I had to use them to charge, yep, 20 mins would be enormous.

He recently publicly announced that Tesla drivers will be able to fall asleep at the wheel and wake up at the destination by the end of next year. Doesn't sound like a lot changed in his mindset.

He claims a lot things...

Yes, i don't give a rating to this statement, i just say that Musk is not conservative about this topic as op suggested. If you ask me, I don't think that they will be anything close to that by the end of 2020

Remember there are some Europeans around running 240v ;) Also, at least on the bigger European cities, apartments and flats are more popular than houses, son usually the energy need is lower. And, of course, energy prices! Here, in Madrid, most of my friends are running 10 to 20 amps. I'm an outlier, running 25amps (5.75 kW) because all my stuff is electric (water heater, cold/hot air conditioning, microwave, glass-c…

> supposing you're using 110volts your desktop computer must be a big gaming rig if it's consuming 350 to 550watts ;) Yup. :-D Not a BIG rig, but certainly respectable. i9-9900k [0], GeForce GTX 1070 [1], 32 gig of DDR4, 1 TB NVMe, 1 TB SSD, 2 TB HD.

I have a relatively simple GPU with my Rizen, it's ok for my use and GPUs are damn expensive, I understand ;)

BTW, have you metered your consumption? Doing some math on the top of my head, on regular use you "shouldn't" go over 200W and I don't think you should get over 400 in your use peaks. Just out of curiosity because I'm not used to those relatively power hungry GPUs :)

But you don't need that much every day. You need to charge the amount you use every day during the time the car is outside during the day, or only part of that. What if you can use the car every day and only have to charge it at a station once a week or month? Then there is even one less reason to use an ICE for those that can't charge at home

You'd have to be more specific than that. You can disable data sharing if you prefer.

"Data sharing" is pretty vague but assuming you are talking about car data, it's completely decoupled from the VIN or any other identifiers that could ID you, so disabling it is just silly, but yes you can choose to not opt in.

Anonymized data isn't really anonymous

I'm waiting for the electric self-driving RV. Who needs a house?

Interesting, so your house drops you off at work, and then picks you up later.

We'll probably see this before we see mass adoption of remote work.

Then he fires them constantly or frustrates the hell out of them until they quit. Elon is a bad boss.

Then how come the team does good work? "Firing constantly" sounds exactly like weeding out unproductive members (of course I now nothing about the workers' feelings, though).

No, a lot of very good folks are shed by Elon's companies all the time. He's just not an effective manager, Tesla is in great measure successful despite Elon, not because of him, and his limitations as a manager are becoming more and more of an obstacle. I have first hand knowledge of that.
