More EV fires after salt water flooding

[IMA SOL MAN]

We kinda did, when we voted for people who approved open borders and allowed flood of refugees come in, we did not vote against them either, (case of, "the other side did not have good candidates")

Not to mention your city declaring itself a sanctuary city. So, okay, you got what you asked for. Don't expect sympathy from the red states that knew what was going to happen. Suck it up, Buttercup!

NY has a right to shelter in its constitution?! Someone must have filled the statehouse with smoke from opium or pot! They must have been high on something! Bunch of stupid utopians.

That's exactly why pot is being legalized all over the place. Dumb down the electorate even more.
They use the words "tax revenue" to coax the folks into supporting it. "Hey dude you gonna vote?" "Uh, naw man those guys are crooks, hey man quit bogarting that joint".

Some want to legalize the other illegal drugs too.

If car companies were serious about selling EVs to the masses.... They wouldn't. They'd sell us advanced hybrids. You hit the brakes, the battery gets recharged. Concentrate on improving that technology. Low on electrical power? Just pull into any countless numbers of existing gas stations and fuel up the gasoline-powered engine. Pay significantly less money, use up significantly less gasoline/resources than if you had a traditional ICE vehicle.

Oh I'm sorry! The above is based on common frickin' sense. So of course no car company will actually do that. Bad Mono!

I'll go stand in the corner with my back turned until America stops electing stupid people. So yeah, someone please check on me every decade to make sure I'm still alive. Thanks!

Yep, and I think they should, it is not like they can stop or even put a dent into drug trade, but it creates cartels, gangs, and lots of crimes around it. what is the biggest money maker all gangs involved in, drug trade.

YEa, it worked out great, right?
And please stop with this abortion bs, you really care about abortions that most likely will never be an issue in your life, and in lives of vast majority of people, over public safety, law and order, taxes, economy.,,,etc issues that affect everyone every single minute of your and their life????

I couldn't care less about abortion but those with a hard-line stance against it just won't get elected in most of NY, even if they're good on other issues people care about.

I agree there. Making drugs illegal falls into the category of protecting people from themselves. This is something I've always been vehemently against. As you said, making drugs illegal doesn't stop people from using them. It simply enriches a bunch of unsavory people. When these gangs have their turf wars, innocent people die in the crossfire. I'd rather an addict gets their pot, crack, meth, whatever from CVS or Walgreens. Either way they'll still be an addict, but at least we'll get tax revenue.

We tried making another drug illegal once, namely alcohol. How did that work out?

It is regenerative breaking, it is used with all hybrids.

Yes, but I have a funny feeling that if car companies wanted to, they could make it far more efficient and effective than it currently is. They just choose not to.

Maybe a little bit more, at the cost of other features, or price, complexity.
Car manufacturers have to navigate a thin line, a compromise between economy, safety, regulation, complexity reliability, .... etc. tuners can modify 100hp engine make 300, but it will not pass emissions, not be reliable, and burn tons of fuel

Up to a point. I know this from my years of having trains as a hobby. Trains use regenerative braking, only they term it dynamic braking. Same basic principles. The motor runs as a generator. The power generated is either put back into the third rail/catenary for use by other trains, or burned up in resistor grids. They've been using dynamic braking at least since the 1940s, maybe earlier.

Anyway, when you look at curves, it turns out at best you get about half the amount of torque from dynamic braking as you do running the motors for acceleration. Too many technical reasons to get into as to why, but that's the case. On top of that, you have power limits for the motors. These apply whether operating as motors or generators. These power limits come into play at higher speeds.

Let's try to show some numbers. Let's say an EV has motor rated at 250 HP. The same motor also obviously has a maximum torque. That limits the acceleration off the line, although for most EVs the real limit when starting off is tire traction. The motor makes more than enough torque to break the tires loose. Let's say the maximum acceleration off the line is 0.8g. That means best case you'll get about 0.4 or 0.5g from dynamic braking, and that's only at speeds where the power limits of the motor don't come into play. If you have a 4,500 pound EV, 0.4g translates to 1,800 pounds of force. To not exceed the 250 HP limit of the motors, this amount of force is only available up to around 52 mph. Beyond that, the power limits of the motor reduce the force available for dynamic braking. At 80 mph you would only have around 1170 pounds of force available for braking.

It gets even more complicated. Often even if the motor can brake up to its power limits the battery just isn't receptive to taking on charge that quickly. At that point then you either limit the braking to whatever power the battery can absorb, or burn the excess power in resistor grids, like they've done with trains. To my knowledge no car does this. So that's why dynamic braking isn't more effective. There's talk now of using supercaps to absorb whatever the motor can generate, then discharging those caps to charge the battery at a rate it can absorb. Until supercaps become a lot cheaper, that likely won't happen.

Then there's the issue of when and how much to use regen braking. I personally don't like regen brakes which come on whenever you lift off the accelerator. That assumes that you don't want to just coast. I'd rather the regen brakes only come on when you hit the brake pedal. Depending upon the amount of braking called for, you can be using all regen braking, or a combination of regen and friction brakes. Again, trains have been doing this for decades.

Ideally, EVs would be using regen braking all the time, regardless of deceleration rates. We may get there eventually.

Human trafficking has surpassed that.

Back in the early 80's, the Missus and I were shopping for a car. I had heard about the new VW diesel Rabbit that got 40 mpg, so I decided to give it a test drive. Got out of town on the highway that the dealer was on--headed up a slight grade, 55 mph, A/C on. Stepped on it, it didn't budge off 55 mph--no HP. That killed it for us. We ended up getting a used 1977 F.I. gasoline Rabbit. Great power, quick acceleration, gas mileage wasn't bad, IIRC around 32-35. It had enough power to start out in 2nd gear, then shift into 4th--1st gear you could spin the tires.

One of our mechanics had a 300sdl, great looking car, roomy, comfortable, but barely moved. serious lack of power.

One of my mother's coworkers in the same time period had I think a Chevy Chevette. I might have even been diesel but my memory of it is foggy at this point. Pretty much the same thing as the diesel Rabbit. I think he timed the 0 to 60 mph at 30 seconds! That's not much faster than a bus, but at least the bus has its size to make people avoid it.

But yeah, they could make automobiles more fuel efficient. They just choose to build what sells in America. Horsepower. My old 4 cylinder Ford Ranger couldn't hardly get out of it's own way but it sure went a long ways on a tank of fuel. 0-60 eventually. It was great on flat ground but in the mountains, you were shifting like an F1 driver. Great truck though. Most opted for the 6 cylinder version though. Because: horsepower.

With EVs at least there's no longer that tradeoff. Same with hybrids having a small battery.

Shifting and noise are two things I never liked about ICEs. When you get rid of the noise it's amazing what a totally different experience it is. Look at this hub motor electric motorcycle:



Just wind noise at high speeds. No shifting. Easy to ride. A 5 year old could probably control it if they could reach the controls. It's surreal seeing the thing move along without the usual racket motorcycles make. Besides, the engine vibration has to fatigue the rider after a while.

0-60mph. in 30 seconds!
Good gracious, that is horrifying!
First car I ever owned was a 1998 Ford Escort Sedan with the 110hp engine. One day, on an abandoned but flat, straight stretch of road, I decided to put it to the test. Two runs from a full stop. 0-60mph. in 13.5 seconds! It was awful! I was constantly white-knuckling it every single time I had to enter an expressway. I wished I could change two things. Just two. A more powerful engine, and having a center armrest.

Next car, both issues fixed! But 0-60mph. in 30 seconds??
I think a golf cart can go faster than that. Not a VW Golf.
I mean a legit golf cart. Heck, on a good day;
I think I can run faster than that!

yea, than it was replaced by 350sdl, his car was over 20 years old still was in perfect shape, no issues. if he did not crash it, it may even be running today
