I can't compare to other performance cars since this is the first one I've owned. It does great on the highway and passing though I imagine some of the other performance cars do better. There is no lag which is nice so it is extremely responsive. Handling is quite good, not as good as the P85+ but it does quite well, especially given its weight. It's certainly fun to drive on those windy mountain roads, and the high torque does quite well on steep grades. It's also quite forgiving considering how much torque it has and the traction control works extremely well at holding the tires at the edge with just a little slip unlike other cars I have driven. I haven't driven the P85D yet and they stopped making the P85 (which is what I have).

The difference is that I can charge at home overnight to a full battery in my garage and I spend 5 seconds plugging in at night and 5 seconds unplugging in the morning. The beauty of it is that I don't need to go to a filling station except on long trips.

As more and more charging stations go in, most charging will happen at home and/or work where charging time doesn't matter.

Currently Tesla charges at over 250 amps with their superchargers and I charge mine at home at 80 amps. As you say, though, the biggest limitations will be cooling and just getting that much current into the car. I think it's amazing that Tesla is able to handle 120KW through their current connector (and I hear they're experimenting with 150KW). None of the other charging connectors come close to this. They might also need to increase their active cooling of the batteries.

Right now my P85 will draw upwards of 310KW from the battery pack, but only for short bursts when accelerating hard.

Charging this fast might require something similar to their battery swapping, with a large connector built directly in to the battery along with support for the coolant loop where something comes up under the car to charge and actively cool the battery when handling so much current.

Peter Jackson ripped the soul out of Lord of the Rings when he neglected to film The Scouring of the Shire.

But he did film it, kinda. He just didn't put it into the story. It shows up a little bit in the Mirror of Galadriel sequence.

One could argue that that was the correct way to play it, too. I know people who claim to have "walked out of the theater after the first ending and skipped all of the other ones," as it is.

You can turn that off, I havent seen a tv yet that didnt have interpolation as an option the user could turn off. Sometimes they give it some gimmicky name though

Yeah, on my set there are two settings that combine to create the effect and I have each set to "most of the way off" because that's the way I like it.

Instead of automatically repealing it, extend its definition of labor unions to include forms of contingent/temporary/non-FT labor - and that such definition supercedes any state definition.

Sch forms of labor would then compete with the choice of a more secure job arrangement wherever RTW is enacted, as opposed to being used as a benefits/etc. dodge for entities operating under a defective business model.

That's the idea. Basically the idea is that you do most charging at home. When I'm planning to go on a long trip I'll set up my Tesla to charge to 100% before I leave home so I spend less time at the supercharger on the way to my destination. Battery swapping doesn't make a lot of sense except for long trips, for example between SF and LA.

I work for an aerospace cabin integrator and we're always looking for good TechPubs people. My company offers fully paid classes within our field. The great thing is that the TechPubs folks work hand in hand with the engineers. You can talk with them and figure what type of engineering work you want to do, stress, electrical, structures, flam, systems, furniture... and we just touch the inside of an airliner.

They've been doing that for years in my city to brackish water to supplement the water supply. The problem is that these last few years have been exceptionally dry. You can't just build desalination plants overnight, especially for the amount of water we're talking about, plus it needs to be transported quite a distance and is very expensive. Most of the water is used for agriculture. California produces around 1/3 of all of the food in the country.
