When they added credit card readers to all the pumps?
My local Shell station recently switched from card readers to an app and QR codes. No thanks. If I'm really desperate I'll fill up there and go inside to pay (maybe 3 times in the past year), otherwise I now go out of my way to fill up elsewhere.

I wonder if one day highways will have wireless power transfer that can meter you as you go.
Germany is building a wired one on A1 (5km length). Overhead contact line for trucks and looks ugly: http://www.thedrive.com/news/13448/germany-to-install-overhe...

Ah, just like internet service: it is oversubscribed. The utility can not deliver what has been promised for all customers at the same time.
Yes, although it not really "promised". A 200A residential service isn't a promise you can consume 200A 24/7, it's just the "never exceed" rating. If you need significantly more power than normal residential needs, I'm sure the utility will be happy to talk to you about your requirements.
The much bigger news is they completely walked back FSD (full self-driving) into something that you have to monitor at all times by changing the description on their website. The release of a proprietary charger is somehow completely overshadowing that news. It's changed from driving itself around in a ride hailing network to earn you money while you sleep, to now making you always be in the car and pay attention and…
> essentially turning all purchasers into unpaid neural network training practitioners. Pretty sure customer data isn't uploaded en masse to train networks at Tesla.

Have you ever considered how much chemical energy is flowing through the gas pump when you fill up a car?
I got curious and did the math: US gas pumps do 10 gallons per minute, which give us 0.61 L/s. Density is about 0.7kg/L, energy content is about 46.7 MJ/kg. Multiplying the three we get juuust under 20MJ/s or 20MW or about 80 times more energy than this kind of electric charger
For now, I can't imagine my next car being anything but a Tesla.
I'm waiting for the electric self-driving RV. Who needs a house?
Cover the roof with solar panels (say 40' x 8' = 10 x 500w panels = 5000 watts of electricity). 8h x 5kw = 40kwh.
If the battery pack was a 1000d, you could move with a full charge once a month for free.
Or you could use it for living too (fridge, range, etc)

I checked now and the fuses are 15 A + 15 A, but the utility company disconnects me if I go over about 4 kW (18 A), or over 3.3 kW for more than a few minutes. My sister-in-law has an induction stove, so she gets 40 A and the stove is connected directly to a separate bigger fuse.
That is really strange. Here, the utility company would be happy to have you buy lots more power. Are you lacking a meter? Is the utility company unable to read your meter remotely and unwilling to send a truck out to read it? This would explain things, in which case you'd want to charge batteries (for free!) whenever you don't need all the power you have purchased. Fuses are weird too. Those went out of style 60 yea…
It is just the standard here to only buy 3.3 kW unless you have induction stoves. Having more power available costs a little more, and on top of that you pay for what you consume.
As to "fuse", my mistake as I am not a native speaker. I meant breaker.

How are overhead lines any more ugly than a sprawling freeway?

Body panels made of solar-cells would be nice, combined with charging from stations or at home when there is not enough sun. Is probably not doable with current technology, but maybe some day
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…

In my language a breaker is called an automatic fuse, so easy mistake to make
