Comment Re:Yawn. (Score 1) 69

Supercharger V2, of which there are thousands deployed and thousands more in construction (with a minimum of two chargers per site), are 145kW. Without any problem to the grid. Supercharger V3 is going to be over 350kW (exact power has not been announced yet). In order to move to the higher capacity, V3 chargers will have a battery buffer, and thus stress the grid less than V2. That is to say, they'll trickle charge from the grid (and their solar awnings, which Tesla is looking to make standard), then surge charge EVs.

Battery swap is a total non-starter for about fifty reasons that aren't worth reiterating yet again here. Every major corporate proponent has either given up on them or gone bankrupt. Including, by the way, Tesla, who was demonstrating their automated swapping system a couple years ago, but has since cancelled it. It's technologically possible, but grossly economically impractical (due to stockpiling requirements, made worse by the unavoidable necessity for widely varying battery profiles and performance characteristics, as well as the ever-changing technological baseline) and gets poor consumer acceptance in practice (as there's widespread opposition to giving up your good new battery pack for someone else's old degraded battery pack). There's also concerns about durability when you're replacing such a large structural element in the vehicle with HV connectors, although this issue comes in a distant third.

Comment Re:happened to me, unfortunately (Score 1) 412

after I had 2 vasectomies. The first failed..

Protocol here is to (1) cauterise both ends of the severed vasa, and (2) perform a sperm count 3 months after operation, before authorising the cessation of the contraception already in use.

the second "succeeded" only to fail 3 years later.

That strongly suggests that your practitioner wasn't using any sort of cauterisation, which does have a significant failure rate. If you informed the second practitioner of the failed first vasectomy (they'd have seen the scars anyway), then not performing the cauterisation step is pretty well down the road to malpractice. Normally, I'm not one for promoting "sue the doctor" at any event, but in this case it does strike me as being a pretty basic failure.

In the UK, using the [cut, remove cm-length, cauterise] protocol, spontaneous reconnection rates are under 1%, which would suggest you're a 1-in-10,000 event. If your practitioners are using a proven protocol, and doing it properly.

"A genre or character in art or literature that features a female that has all feminine attributes except that she has a penis. This can include her having a vagina, .." Most likely NSFW, but otherwise it's just the well-known "shemale" trope. You can find adverts for this in your local newspaper - look for the keyword "operation".

Scots only started wearing kilts (as ceremonial garb) in around 1820 (Georgy-Porgy's visit to Edinburgh), and few wear them as day-to-day garb today. Before then, they'd often wind the pleid mhor around the legs to form a loose pair of "trews", or as would be described elsewhere, loincloths. By the way, "Braveheart" was stirring uplifting bullshit.

Comment Re: Wild guess (Score 1) 412

The word you're looking for is "plasticisers", not "plastics". Plastics are, by definition, large, polymeric molecules which are essentially immobile under physiological conditions. "Plasticisers" on the other hand are small mobile molecules which disrupt the adhesion between polymer chains (not limited to cross-linking, though that is something you want to control too), making the bulk mixture more flexible and elastic. (Sometimes plasticity is desired, but more often elasticity.) Plasticiser molecules are far more mobile under physiologically relevant conditions than plastic polymers. Just to confuse the matter (not that plastics chemistry isn't already the subject of dozens of journals and hundreds of thousands of published papers - and the proprietory work within companies), some monomers which have not polymerised into the bulk plastic act as plasticisers - and also remain mobile.

> Because they have limited range, take too long to charge

Mostly this, right, trying to do a 1600km (1000 miles) trip in an ICE vehicle? I can do it with just 2 tanks of gas in 16h. However with an AV?

I don't know how you would do a 1600km (1000 mile) trip within Britain in any kind of car, electric or petrol. Unless it floats.

Comment transmission losses (Score 1) 397

...With about 65% of that energy lost in transmission, that number doubles.

65% loss?!? What do you think they are they using to transmit, wet string?

The link you cite says "Energy lost in transmission and distribution: About 6% – 2% in transmission and 4% in distribution".

But Britain's a small place, and they don't wheel power thousands of miles (they don't have thousands of miles), so I expect a smaller number is appropriate.

Comment Great island for electric cars (Score 1, Insightful) 397

We'll see what happens to their economies when these bans are ready to take place, I will bet that they end up backing off rather than crippling themselves (or people will end up using a lot more used cars and trucks until they vote the bums out)

I don't see any reason why not selling petrol cars would "cripple" Britain. You do know that it's a tiny little island by American standards of distance-- all of the U.K. is still a little smaller than Michigan-- and few people drive long distances. As far as I can see, it's a great location for electric cars.

Comment Different uses, different cars (Score 1) 397

limited range, long recharge time, what little infrastructure there is to support it, is typically broken, price, longevity. just off the top of my head

Depends on what you need.
Almost all of my driving is around town, and it turns out that this is actually very typical-- most people use cars for mostly short trips. Actually, a ten mile range would be fine for me-- we're a two-car family, so it would be practical to have one car used for most of our uses, and when we do need longer range, we could use the other.

I have a perfectly good ten-year-old car, so I don't need a new car now-- but when I replace it, an electric car makes sense.

The take-away lesson is that different people have different needs for which they use their car.
