Electric vehicles during a disaster

[5030]

80 is the de facto minimum out here. The mileage difference is minimal, in my experience. Weather has a much bigger impact, as does elevation changes.

No comment other that physics will prove you wring, every time.

This is all we will have to do if electric vehicles get stranded during emergencies.

Should only take a few hours and you can escape the hurricane or forrest fire.

Just plan ahead!

That 2nd meme was written by an imbecile. The Prius already has a gas engine and a 10 gallon gas tank...that will take it 400-600 miles depending on weather and such.

Again, the minimum speed on any Interstate highway is 45 (if you bother to read the speed limit signs, don't matter what the top posted speed is, that is a Federal law.

What you wrote here is patently and demonstrably false. If you bother to read the Constitution, you would understand that there can be no Federal law setting speed limits. The infamous 55 'set' temporarily by Nixon and 'permanently' by Carter were not Federal speed limits. They were Federal coercion of states to lower state limits or face reduced federal funding.

Not all states have the same maximum, nor minimum speed. This makes a lot of sense, because the tiny eastern states don't gain much value in higher speed limits. Out here, higher limits allow us to spend less of our lives on the highway.

Coming in late to this party, but there certainly isn't a shortage of opinions! I'll add mine to the mix.

I won't say I'd never buy an EV, but the economics would have to work out. EVs (to me, anyway) don't make a lick of sense for long trips, and certainly don't make sense to me in an emergency. It's not just the current lack of charging infrastructure, but also the amount of time it takes to charge the things. Also, everything I've seen, even from self-proclaimed "greenies" says that EVs aren't carbon neutral. The fossil fuel it takes to build the things and refine the lithium and other battery components is substantial. There's some advances in battery energy density with aluminum batteries, but still in the lab (from what I understand). If I were a betting man, I'd say hydrogen is going to be the next big thing, and it's going to be produced by the cheapest, cleanest, safest, most energy dense power source currently known to man----the nuclear power plant.

Back in the mid '80s I worked with a college student from Missoula. He used to tell about the violation if you got caught speeding on the highway out there... a dollar fine for "Squandering a natural resource." I don't know if it's true or not but it sure makes a good story.

About twice a month I travel 200 miles each way to visit my mother. About half of that time is on the interstate, travelling at 70-80 mph. I have calculated the savings vs driving at 65 mph; at 5$/gallon I would save about 7 dollars, but it would take another hour each way. My time is worth more than 7$/hour.

Another hour each way? Something's wrong with the math there...

200 miles at 65 mph = 3.1 hours.
200 miles at 70 mph = 2.7 hours = 4/10 of an hour faster = 24 minutes.
200 miles at 80 mph = 2.5 hours = 6/10 of an hour faster = 36 minutes.

If your traveling 70-80, you're probably saving half an hour at best.

I didn't read all the previous posts so maybe this has already been noted. If so then I apologize for the repeat. Anyway, when we had mostly horse drawn vehicles and gasoline vehicles just started to be on the scene the same type of conversaions were no doubt common. Just the fuel changed." What does you carriage use? An engine? What is that? How is it powered? Gasoline you say? Where do you get that? "
Then later you hear folks talking about their neighbor and their gasoline powered carriage. "Yeah, my neighbor has one of those gasoline powered carriages. It works good and is pretty fast but where do you buy gasoline? I can get horse feed anywhere. And the roads won't let you go very fast anyway. And who can work on the things?
Then later someone says that they got rid of their horses and bought a gasoline powered truck and tractor. "Yeah, I gotta go into town and buy gasoline and it's a hassle but my tractor never gets tired and costs less to feed than what gasoline costs compared to hay and oats and I save a bunch of time driving my truck into town to fill up my gasoline barrels compared to getting hay and oats for the horses. And a new gasoline station is being built closer to me, I can hardly wait."
Then later we have gas stations everywhere.
Then now there are not as near as many gas stations as there used to be, and almost none of them are service stations. Part of the reason is because of the much better mileage vehicles get and much less service they need.
And then just last week I saw a parking lot in Seattle, just some space unused that a property owner turned into parking spaces, and now they have added two charging spaces. So they earn money for parking and charging.
It won't be too long before electric vehicles outnumber internal combustion vehicles. If I ever buy another vehicle it will be electric. The infrastructure will catch up.

The ability to produce that much electricity will not catch up...the people who push EV only also do not want nuclear power. The number of charging stations is irrelevant in the larger calculus. There is a place for EV, but it is supplementary.

The difference between your story about the past and the present is that by the time the car reached the stage that EV is today, it was abundantly clear that the car was superior in almost every way to the horse drawn carriage. There are few ways that EV is superior to gas/diesel. You also didn't have the government forcing the issue.

No it's not and you are wrong. On any Intra or Interstate, the minimum posted speed is 45 mph. Obviously, you have tunnel vision and don't observe the signage. Not my issue though. Contrary to your opinion, they all have a minimum 45 mph speed. Just not a top speed. I'm done with you.

I know plenty of EV advocates who are also nuclear advocates.

I think this article shows that it is demonstrably true that at least by 2011, all interstates in the US did not ahave a minimum speed limit of 45mph.

Speeds on Rural Interstate Highways Relative to Posting the 40 mph Minimum Speed Limit | Bureau of Transportation Statistics

I think if you want to make claims that are contrary to what is visible around us then you should be the one to provide the proof. What federal regulation establishes a nationwide 45mph minimum speed limit that may not be changed by the states?

You're right. I meant an hour round trip.

Well, i lived in montana in the 1980’s. There was no daytime speed limit, only night time limits. Cops would pass me as my bronco was doing 85.

Okey dokey. I thought maybe you had an interesting highway system over there. You know. Uphill both ways in winter with one shoe.

Well, I lived in Indiana in the1980's.... nothing much more to say about that.

Lotta corn.

 

[grsthegreat]

Thats nothing… nothing is scarier than a 1978 bronco doing 85. Not sure why it didnt fall apart.

Hubris does not look good on you. Take a step back and open yourself to learning new info.

Here's an example from Florida...

"The minimum speed limit on all highways that comprise a part of the National System of Interstate and Defense Highways and have not fewer than four lanes is 40 miles per hour, except that when the posted speed limit is 70 miles per hour, the minimum speed limit is 50 miles per hour.".

See section 2, below.

I wonder if they have EV chargers at Indiana Beach?

 

[Grumpycat]

That is a big if. I've read a few articles where they tested one towing a heavy trailer. It does the same thing to the EV that is does to the ICE trucks. It greatly increases fuel consumption. With an ICE you just refuel. With an EV you are lucky to find a charging station.

With a non-Tesla "you are lucky to find a charging station". This is because Ford and others are expecting handouts. Expecting someone else to build charging stations. There is currently 1586 Supercharger sites in the USA. Most have 8 charging bays, most new have 16.

Long ago Tesla offered an olive branch to other manufacturers: Use our Superchargers under equal terms. Those terms included sharing of costs and how the EV must be able to charge as fast as a Tesla and go a similar distance. This stands to reason because one does not want Nissan LEAFs sitting twice as long for half the range of a Tesla, and even then not being able to drive 100-125 miles to the next Supercharger. That I know one very small manufacturer accepted Tesla's offer but is not yet in production.

Then it might be in use or you might have to sit there for 30 minutes or longer. That is not going to work. I live in Texas and everywhere I drive is usually at least 20 to 30 minutes each way. I would be so stressed out if I could not easily refuel. I am hoping to get a new truck in the next few years before the government says I have to buy an EV. I agree that we should be using hybrids more.

Then why do you not have a hybrid right now? You want someone to give it to you?

An EV starts from home with a full charge (or as full as you desire) every morning. With 200-250 miles in the battery you will have no trouble going several "30 minutes each way" each day. Then you will spend 15 seconds connecting the EVSE umbilical at night, another totally wasted 15 seconds unplugging the next morning.

40+ years ago attending university 110 miles from home I often wondered about what it would take to drive the route with an electric car. As an engineering student I did math and realized it wasn't going to happen with 12 volt lead-acid batteries. Now I have driven that same route round trip on one charge in an EV.

Irony: Relying on electricity to operate gas pumps is the same as needing a gas generator to charge your EV.

My Prius had an 11.9 gallon gas tank.
