Hi, thread. I'm trying to branch out to more of SA. This seems like a nice thread.

My wife and I have a Model 3 and my daughter has a Leaf. They're both fun in different ways: the Tesla is like a batmobile, and the Leaf is fun to upgrade with all the aftermarket dashcams and stereos and stuff.

Cruftette Jr has been driving this 80-mile round-trip three times a week, and it costs her between 60¢ and $1.20 to charge enough to get back home, depending on whether she remembered to charge up the day before. $1.20 would have gotten her diddly squat range in our old Subaru. This is awesome.

If anybody in here has any experience with the thing where you can run current out of the Leaf and into your house, I'd love to hear about how it's going for you.

The moment dieselgate got exposed to the world, an electric VW microbus should have become priority #1 for the whole company.

Instead, we’re getting it in 2023.

Maybe. If they feel like it.

I'm pretty sure this is exactly how it played out, it's just that converting multiple production lines to a radically different drivetrain is incredibly complicated, even if you've been making cars for almost a century and know a thing or two about manufacturing.

Did anybody ever answer the question in the thread title?

It's 48.6.

A Powerwall 2 has 13.5 kWh, which is 48.6 megajoules. A stick of dynamite is about 1 megajoule. So 48.6 sticks of dynamite is equivalent to one Powerwall.

E: a gallon of gasoline is about 33.41kWh per gallon [source]. So a Powerwall 2 is equivalent to 4/10 a gallon of gasoline, and my Model 3 has enough batteries to store the equivalent of 2 gallons of gasoline. Gasoline has a lot of energy in it, and this really illustrates the efficiencies you get with an electric car, I think! Imagine going 353 miles on 2 gallons of gasoline!

I don't think the energy in a stick of dynamite is, like, super accurately defined, so "about 50" is probably as good an answer as 48.6.

Edit: apologies if this has been covered, but is it typically “better” to lease an EV vs buying one? I ask since I assume after three years there will be a better model of whichever vehicle I end up going with.

I was under the impression it is never in your fiscal interest to lease, regardless of the drivetrain technology. But I heard that 10 years ago, so I'm bumping your question 😉

The thing with EVs generally is that you shouldn't be thinking about when you should or shouldn't charge when you're at home; If you're home it should be plugged in, Period. Even on 110v, there are probably vanishingly few people who couldn't live with an EV if the thing is plugged in whenever they're at home. It's not like you wake up in the morning and go unplug the car even if you're not leaving.

I am of course intentionally disregarding the separate and totally real concern of people who cannot plug the car in at home at all. (Apartments, condos, etc)

You're also disregarding the Leaf's insane algorithm for charging up the 12v lead acid battery.

Getting cables to parked cars in urban areas with sidewalks and inside bike lanes is going to be challenging, and I can't think of any way to do it without overhanging fixtures, which nobody is going to pay for, so there's going to be a lot of senseless fighting in the future about where the cables should go. And I've already seen people suggest "just use public chargers", so, yay, we're all set to continue not listening to one another when it comes to road use.

But in principle, yes, I agree with you.

She was upset that she was going to have to pay to replace it and that Tesla wouldn't let her keep the car for two weeks so she could try to fix it.

The one that made me question why I was still reading was an article about somebody that crammed ground beef into a DC charger in Germany.

One thing that's a real drag about Tesla, for me, is that the nearest service center is a 5 hour drive, and another 5 hours back.

So far they've been really cool about sending out the mobile service unit, so they do everything in my driveway. That's been awesome. But I imagine one day that will stop happening, and then life's going to be pretty awful for me.

E: so I guess it's not a drag currently, it's just a predicted drag.

I bought six EVs and ended up breaking even net, because of Colorado's ridiculous laws around tax rebates for them. I had a Model 3 too - it's an awesome car but the earlier LR AWD model had issues with cold, long trips. My breaking point with that one was being in Taos, NM and being routed to Pagosa Springs, CO - route planner said we could make it, and a third of the way there after constant 'reduce speed to 60, reduce speed to 55, reduce speed to 50' messages even with the heat off we turned around and headed back to Santa Fe. Then there was the time when we took it to Orange County CA and had to wait in a two hour line to charge on a non-holiday weekend. Or the new 40kWh Leaf that had a battery voltage sag when under heavy load in cold temps (SoC would dip 20% in a mile, then climb back up when I let off the accelerator). But shorter trips with L2 charging at home were always nice.

Again, this is not a personal attack on EV drivers. I just found that the frustrations related to them started to add up for me and they weren't saving me any money compared to a very efficient gas car.

Yeah, I get this. I live near Taos, and driving to Denver requires more planning now than it did in the Subaru, due to charging. We can do it, but we have to remember that I25 has crazy headwinds sometimes when you're driving north, and the trip planner doesn't factor this into its "safe to continue your trip" calculation.

EV technology seems mature compared to what it was like in 2001, but when you hold that up against something that's been around since 1886, it's clear that we're still dealing with a technology that has a lot of improvements yet to come.

In this poster's case, the main improvement would be more friggin' charging stations. Taos has diddly squat (I've checked) unless you fancy a 6-hour charging session. There are, by contrast, plenty of gas stations in Taos.

And to that same point, one of the main reasons we got a Tesla to replace our Tesla instead of literally anything else is because we couldn't see how we would be able to take road trips with something that needed CCS chargers. They just aren't out here yet. Tesla has a big advantage there, and even with that advantage, stellers bae couldn't get to Pagosa Springs because Tesla's "best charging network on the planet" still has huge gaps in it.

There's this area in between Needles and San Bernardino where gas is never under $7 a gallon. I've bought gas there before because I failed to take into account that ubiquitous gas stations are not a given, and I didn't fuel up when I should have. I was happy to pay far out the rear end in order to avoid being stranded in the middle of death valley.

When there are people happy to pay $7 per kWh to charge up in the middle of nowhere because they made a bad decision earlier, I think we can finally claim charging infrastructure is on par with gasoline. Right now you can't even go to Pagosa Springs with Taos as your home base.

We have a way to go, but I suspect charging stations are being built out way faster than gas stations were.

My kid had trouble getting the incredibly beat up CHAdeMO connector plugged in correctly, and it billed her $21 for 5 kWh. So it turns out it's $7 per connection attempt.

The area north of Espanola to Chama is Carson National Forest. There will probably never be any superchargers put in there, it's desolate as poo poo. Pretty though. Chama is a pretty small town, but it's an important intersection in the area, so I can see them putting one in there, maybe. North of that there's not much to Pagosa.

I would have thought little towns wouldn't install chargers any time soon, but there's a 350kW CCS charger in friggin' Wagon Mound so apparently I just don't understand the economics here. https://goo.gl/maps/geDtHukL7pbjwkCf7. Granted that's on I-25, but it's friggin' Wagon Mound, population 268.

There are dozens of gas stations between Española and Pagosa Springs. If just one of them put in a ChargePoint station it'd be a game changer. Hell, if they put one in Taos I'd probably pony up for a CCS to Tesla adapter just to not have to plan charging for my trips any more.

Rivian is specifically targeting more remote areas for their DCFC network! :eng101: The decision from RJ to do this was because Rivian is advertising their trucks and SUVs as adventure vehicles, so we want people to be comfortable going to more remote locations!

That's awesome, because in my experience that's the biggest gap right now. It also sounds like a huge challenge because there are so many more remote sites. I was relieved to find out Rivian is using plain old CCS, contrary to dumb rumors I'd heard earlier about a new proprietary connector.

I hope one day Tesla's charging network can be used by non-Teslas, but when I look at how quickly CCS chargers are getting built out now I can't help but feel like it's increasingly irrelevant.

With autonomous cars we are finally seeing this shift. Every once in a while now, the automaker's liabile when their product runs someone over. And, amazingly, for the first time, people are generally coming around to the idea that the automaker should be liable.

New thread title, new answer!

Birds don't fart. But there is probably some gas that comes out of a bird cloaca occasionally, which could be argued to be a "bird fart". Methane is a very common organic gas, let's pretend it's methane. Say, for a common crow, 0.5 cm³ of methane per fart.

Methane has an energy density of 39MJ / m³. And dynamite, remember, is about 1MJ / stick. Let's cancel some units!



0.0000195 sticks of dynamite are equivalent to a presumed crow fart. Put another way, you'd need to ignite 51,282 crow farts to get the energy of one stick of dynamite.
