Comment Re:Taller hoods? (Score 4, Interesting) 316

One does not negate the other.

That said, my own current work car is a 2025 Chevy Equinox. I previously had a 2021 Equinox. The 2025 pushed the top of the hood up a good 3-4 inches compared to the previous, and changed a few other functional angles as well. The goal was evidently the "truckification" of a small crossover SUV. The result was terrible. Sight lines are dramatically worse out of the front of the vehicle. Short people can disappear in front of the hood now that it is that much taller. This is even worse on actual trucks; Chevy Silverado full-sized pickups are leaving dealer lots with hoods that are 5 feet off the ground for no functional reason.

It is fair to point out that such collisions shouldn't happen often at normal driving speed. However you're overlooking other places where collisions do happen often between vehicles and pedestrians; namely parking lots and driveways. While the new cars have far more mandatory cameras to help drivers spot obstacles, they don't prevent every situation. Car manufacturers should be taken to the woodshed over this awful decision, and it's not just the American auto makers.

Ever wonder why so many new pickups pull backwards into parking spots? I had a new Silverado recently as a rental and I believe I discovered why. Those new trucks don't have forward facing cameras, but they do have backup cameras. They sit so high the driver can't easily see the lines or obstacles in front while attempting to park but when backing up the camera shows what's coming up behind. Terrible, terrible decisions.

Comment That's minor compared to iPhone outlook (Score 1) 68

My work phone is an iPhone, and we're required to use Outlook for work email. On average outlook gets patched twice a week for iPhone. The biggest flaw in it though has been there for years and clearly won't get patched.

Namely, Outlook for iPhone always defaults to reply all for emails with multiple recipients. It doesn't matter how long the list is, it will reply all unless you go out of your way to reply only to the sender. This has catastrophic consequences at large companies.

It is not uncommon to have email threads at my employer with dozens, or even over 100, recipients. When one goes out with any ambiguity we quickly see who on the list is reading it on their iPhone (vs their laptop) as they inevitably will end up doing a reply all without meaning to.

Apparently Microsoft sees this as a feature, even though they don't force this feature upon us in Windows.

Comment Re:I want to see inexpensive plugin hybrids but .. (Score 1) 135

You might want to read up on how current hybrid vehicles actually work, 'cause it seems you have more than one misconception going on.

I have. For instance, my latest vehicle is the Ford F-159 XLT,, the full-hybrid model of the F-series pickup truck line. Power train is:
  - 6 cylinder dual-turbo engine. (runs low power but approoximately doubles output when a lot is needed.)
  - 47 HP motor-generator "pancake" on the engine side of the ttransmission, to scavenge / return power to./from a 1.5 kWhr lithium battery.
  - 10-speed automatic transmission, working with the lithium battery;s main alternator to fine-tune match the engine/mogen to the current driving situation. Max power of engine plus hybrid mogen; 430 hp.
  - full four wheel drive.

So it's primarily a gas-engine power train with an electric-car motor mechanically coupled to the engine shaft. Many other hybrids, from the venerable prius onward, are similar, with plug-in variants having a big scavaging/peaking battery good for pure electric operation of tens of miles rather than a minute or so and a wall-powered charger added.

What I'm looking for is essentially a pure electric - totally electronic "transmission" consisting of alternator(s) between the batteries and the motor(s), plus a tiny engine-generator able to burn gas and feed some teens of KW of charging power into the batteries when running down the road or parked near it.
 

Comment cobalt chemistry, not so nice. (Score 1) 115

Do the Waymo batteries use one of the lithium chemistries including cobalt, or a non-cobalt chemistry such as lithium iron phosphate?

Cobalt chemistries have a higher power/weight and energy/weight ratio, which made them the go-to chemistries for vehicle batteries. But they also produce oxygen when the cells overheat, leading to an unextinguishable runaway fire hazard: A burning cell makes enough heat to ignite the adjacent cells, so the whole assembly of them goes. Bad enough when it's a car's worth, but a disaster if it's a shipping-container sized module of a utility energy storage site. (And even worse when the site is a building full of racks, which someone had "protected" from fire with water-spraying, equipment-shorting system, so the whole site burns up, as happened recently with one in California creating a toxic mess.)

That's why purpose-built stationary lithium energy systems use non-cobalt chemistries - heavier, but a shorted cell just kills itself without getting hot enough to light off its neighbors.

I want to see inexpensive plugin hybrids.

But not like the current ones, which are primarily an engine/tranny powertrain with a motor/generator + small battery for scavenging downhill/braking energy for later accelleration/uphill/cruise/power-boost.

I want ones that are primarily a battery-electric with a small aux engine-generator (say 15-20 HP range), big enough to power crusing with a bit left over for gradually charging. That would let you range-extend by the size of your gas tank plus fillups (i.e. indefinitely if only gas is available) or go from battery empty to back on the road in a couple tens of minutes.

The backup engine would only run at max-efficiency speed and could use an atkins-like cycle (see "liquid piston engine") to get the max power out of the fuel. Most operation would use power-grid charging (when available and cheaper than fuel).

As I stated though, I fully expect that when the GOP digs themselves out of Trumpism, they will eventually deploy the "No True Scotsman" defense to claim that their cult leader was not a "true conservative" all along. But when they move the goalposts that far, will they be required to look at what they have so willingly mischaracterized in the past on the other side?

Comment Re:The DNC is not socialist or communist (Score 1) 10

I've seen people make that argument before, that there is no difference. You can make that argument if you want, but if you can't provide a viable candidate then you're not helping anything.

Let me be extra direct here. I have never seen a candidate in a race I could vote in that I agreed with 100%. Frankly anytime I meet someone who tells me they agree with a politician 100% of the time I tend to want to tell them they need their head examined (unless they are themselves a politician, in which case doubly so). Even politicians like Bernie Sanders I don't agree with 100% of the time.

Complaining about the rules is not productive. We've seen what the SCOTUS will do about such arguments, we can't get help from them either. The only way to advance is to support someone who will actually do something useful. Pretending that they all do the same shit doesn't help either; there are meaningful platform differences. Just because Drumpf has held every position on every issue doesn't mean he doesn't stand for anything, either - he's actually followed through on some of his (very worst) initial promises.
