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

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

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.

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

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

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 interve

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 assumptio

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 dir

Strategy is valued by a lot of viewers, myself included. As I pointed out the victory by the mathematician Anna Kiesenhofer in cycling was amazing to see, even though there was no dramatic race, because she used more math and strategy tha

My error. I thought I had the premium service as an Xfinity customer, and the ads were just showing up because these were sports recorded live. I definitely would have done that knowing. Well, almost definitely. Streaming DVR is just

While computer camera/laser judged pole vault/high jump would certainly be possible, and much quicker, they would be different in that the visible bar clearly creates a target in the mind of the athlete. It also has the advantage

Reality is all perception systems occasionally wink out, but they also have object permanence algorithms that know they are not actually doing that. Humans are not so different. You see a car coming up behind you, you look away, you pre

While Forbes does have some articles from paying contributors, these are marked. Articles from "Senior Contributors" involve paying the contributor, not the other way around. So not really like Medium or Substack (Though these

It is challenging, but so far, have people refused to buy products/services they can't repair? Have all those products died in the market as a foregone conclusion?

Yes, but the road to the mall changes from time to time, and the parking lot in the mall changes (watch a video of Waymo having to deal with a christmas tree lot set up in the parking lot of one of the malls they take a customer to.) No

These systems are expected to be constantly changing and improving, and making use of constant streams of new data on updates to roads, traffic, and more in order to run.

You say there is no way in hell you would trust self driving enough to close your eyes. My experience is most people come to trust it far too soon, not too late. It's not a problem. People trust something when they see it work a co

Correct. While 30 miles is the low end of the predicted ranges (that's more for the pure multirotor vehicles that are nimble but not efficient) these are vehicles for that urban trip. Pick you up, take you to your destination, and w

Neither humans nor robots can treat everywhere like a crosswalk. We human drivers see pedestrians standing on the edge of the road all the time, often getting ready to cross. If we slowed down every time we saw that, roads would flow poor

Humans only drive about 500K miles in a lifetime, though there are those who drive much more. 2 million miles would be a challenge in any human lifetime, but there would be some professional drivers which attain that.

While many people do buy a car every 3 to 5 years, they sell that car to somebody else, and the average car lasts about 19 years, with several owners. On the other hand, cell phones are sometimes resold but not nearly in the same way. Man

Battery swap failed after a $700M investment from Better Place for many reasons. But the big issue is that with battery swap, car owners do not buy or own their battery. But most of the innovation is in the battery. For innovation, you
