> If curb weight is 300 lbs higher this either means 300 lbs less loading of cargo and passengers or facilitating 300 lbs of additional gross weight rating which itself requires added vehicle mass to achieve.

And that extra mass to accommodate is negligible. I'll use a 2020 Hyundai Kona as an example because that's the car I own and I know for a fact the ICE and EV versions are identical in basically every detail not directly related to the drivetrain.

ICE curb weight: About 3000lbs.
Weight of engine + transmission (2.0L MPI Atkinson DOHC + A6GF1-2): ~430 lbs
Net chassis weight: ~2570 lbs

EV curb weight: about 3700 lbs.
EV battery 64kwh pack weight by itself: ~1000lbs.
EV motor, gearbox, inverter: ~200lbs.
Net chassis weight: ~2500 lbs

By your logic, the EV variant would need to weight more than the ICE. That's demonstrably not the case; the chassis is basically identical within the margin of error.

> What "apocalyptic concerns" have I raised?

You personally? I don't know you well enough. But if you look at all the complaints about EVs from 10-15 years ago, and even up to this day, they were making the same arguments as you while claiming our roads and bridges would collapse and all sorts of other nonsense. None of those fears have come to pass.

> EV owners are going thru new tires every other year.

I've owned an EV for five years and the tires still have plenty of tread on them.

> As explained above this is not the case.

Your position is in direct conflict with observable, lived reality.

You forgot the part where you spend over a decade building name recognition and a devoted following who will help make your project a success for the memes alone.

No shade at Markiplier but let's not delude ourselves that any random dude can get the same results; most indie films run at a negative, but in terms of successful indie films Iron Lung is pretty far down the list... though it's not been out that long.

The real lesson here is to find a way to generate hype while keeping budgets low, and it doesn't really matter how much or how little you "play their game."

With weight it literally is, though.

> This translates into increased mass to support the added mass impacting struts, brake, tire and road wear, safety and efficiency.

We're talking about an increase in mass equal to two, maybe three, passengers. You're adding an estimated 5% or so to the total vehicle mass going from LFP to Sodium to keep the same total energy store.

For comparison, 1600lbs to an F150 Lightning is over 25% more vehicle mass. Mass that it was already designed to carry, because that's its bed payload capacity.

Struts for a 3250lbs car are not any larger or heavier than those you'd use on a 3000lbs car. The brakes do not need to be any larger. Tire wear increase is minimal to negligible (despite all the pearl-clutching headlines, reports from actual owners and real world data never indicate accelerated wear). Increase in road wear is absolutely negligible in this weight class.

The arguments you are making now are exactly the same arguments made when EVs first became a big deal (EVs being heavier than ICEvs and all that) and none of those apocalyptic concerns turned out to be true. Hell, cars in general have gotten much heavier than this hypothetical increase and none of what you're saying has been an issue.

But back to the original point; The added weight of a less energy dense battery to get the equivalent kwh will have a negligible impact on range. It's just not a big deal.

> I see this on a regular basis with ICE but it's less than that

19.6 -> 18.0 is an 8% drop in efficiency. 8% is more than 5%, not less.

Granted you'd need to account for speed as well, but considering similar tests are done with gasoline pickups and they also see 8% to 9% decrease in range - still less than 5% - I think you've just helped prove my point that a few hundred pounds extra is not a significant impact on a vehicle's efficiency, no?

Why would you need a charger for each spot in the garage? Does everyone in your household commute 200 miles a day and need to plug in every single night?

They also made dual-cable EVSEs for exactly this reason. Two vehicles, one circuit. This is more a convenience than a necessity though.

I swear every time you post under one of these stories you come up with even more elaborate scenarios to claim that you - and by extension everyone else - simply can't make EVs work.

You are greatly over-stating the effect of weight on efficiency. Yes, a heavier vehicle will be less efficient, but the effect is not that dramatic and virtually negligible for even a couple hundred pounds worth in a vehicle that's already 3000+ pounds.

I recall a test specifically with an F150 Lightning with a water tote in the bed, comparing efficiencies between an empty and full tote (~1600 lbs of water) and getting a difference in efficiency of only 5%.

So let's say the pack is 1000lbs and you need 25% more battery due to lower specific energy. 1250lbs. That extra 250lbs - which is basically equivalent to some passengers and/or cargo - is going to have a negligible impact on range. Well within the noise of day to day driving conditions.

Many (most?) WalMarts already have Electrify America charging spots. They are simply cutting out the third party.

This could potentially be good since WalMart would now be directly responsible for maintenance of the equipment, and if they are unavailable it reflects poorly on them directly.

Wish I could, but unfortunately everything has become so shitty I'm effectively forced to use some app for even basic shit. I avoid using it for anything more than a clock most of the time and the majority of the features it has I will never use or have actively stripped out.

Hell I barely use it as a phone.

If you have to ask someone over and over, phrasing your question differently each time until you get the answer you want, that is not actually helpful or productive. That is just seeming self-affirmation, not seeking information. How's that saying go? if you can tell the difference between good advice and bad advice, you don't need advice.

And when that chatbot is just flat out wrong like a third of the time, leaving you to guess and need to verify everything (assuming you have the self awareness to even question the pulped data it regurgitates) you are definitely not saving any time and probably would have actually retained some of that information had you skipped the AI assistant and just did your own research to begin with.

The stochastic parrot that feeds you platitudes and tells you you're a good boy and oh so smart has rotted your fucking brain and robbed you of the ability to think. Case in point:

> Guaranteed if you idiots lived in 10,000 BC you would be against farming or agriculture

Farming dates back much farther than that, and but when I type "when was agriculture invented" into Google the AI summary gives me exactly the same wrong answer you used. Yes sir, that definitely worked out for you.

Lastly, all the complaints and gripes in that old Slashdot thread you linked? Still valid, and in fact the future that actually came true is so much worse than they were worried about.

Well that's patently false. It wasn't until Win10 was out that Microsoft decided it would not let you install Win7 on CPUs made after ~2017. No technical limitation for that by the way, because both official and unofficial patches existed that would allow it.

And this is not the same as the OS requiring new hardware. This is the OS deliberately rejecting newer hardware. So if you got new hardware, you did not have a choice but to upgrade Windows too.

Some units including the ChargePoint (which I own one) rely on software to set the upper current limit. During installation you tell the unit what the breaker size is, and while you can use the user's app to change the max current at any time, it will not let you go above the breaker rating set during installation. Changing this requires using a special installer's app and connecting to the unit locally via bluetooth.

So if an attacker gains arbitrary code execution ability, I suppose it might be possible to set the max current above the breaker/circuit rating.

Assuming that, if a lot of things go wrong in very specific ways there is a chance of starting a house fire by overloading a circuit. A LOT of things would need to line up though, including the use of a plug and socket and/or faulty installation of the circuit, so that risk is incredibly low. I think the worst plausible damage would be constant nuisance tripping of the breaker.

I can also tell you that the Grizzl-E set their max current via DIP switches inside the unit. I suppose that doesn't make it impossible to change the firmware to ignore the switches, though.

> EUR 3 per cubic meter sounds high. But is still significantly cheaper than the 100ds of dollars some posters here pay, or the article implies.

The article references a table on another website, and that table only lists averages of monthly utility costs by state and with a national average. Per the methodology on that site, the cost for water and sewage is based on an assumed 300 gallons (1.14 cubic meters) household per day and utility rates from *another* website that lists basically the same data.

So if we take the $49/month national average from that cited table (which is where the $1200/yr comes from), divide that by 30 we get $1.63 per day. Again adjusting everything for units, that's 1.22 Euro per cubic meter.

Now, the 300 gal/day average per household includes irrigation (watering lawns and other things) so the per-person water usage is about 60-70 gallons daily. A 15-minute shower would use about 20-30 gallons. Toilets another 10 gallons daily. 25-30 gallons per load of laundry but that's not every single day so... let's smooth that out to 10 gallons a day? (I do 2 small loads per week just for myself but I can see 2-3 larger loads per week). The rest is cooking and general washing/hygiene tasks.

From my *personal* experience 70gal/day is a lot but I can see it, especially if you like long showers or full baths (30-40 gallons).
