2% is probably near the theoretical maximum, too. Actual output considering weather, efficiency losses, etc is probably less than half that. Solidly in “not-worth-it” territory for most use-cases. Heck, my car won’t even properly charge on a 120V outlet when it’s too cold, because it needs to heat up the battery to a safe temperature first and at -20°C that takes more than the ~1kW available from the outlet.
“rich people” in your mind is who, exactly? Here in Canada only cars below a certain MSRP qualify for subsidies, so “luxury barges” are not subsidized. Also, a $50K car is not luxury anymore, have you seen car prices recently? New ICE cars are expensive as hell too!
Pretty sure the conditions on the planet when oil/coal formed were substantially different from today. In particular, there are now various organisms which feed on the decaying matter that’s at the start of that process. These organisms eat that matter and emit CO2 as they live and breathe, returning the carbon to the air instead of burying underground.
You vastly overestimate that. It’s not a fixed number of cycles, it’s a number before significant degradation. In other words, after you’ve spent ~8000 hours driving, you’ll have to recharge about 40 minutes earlier.
If you think your ICE car is still top shape after that long, go ahead man… But in all likelihood, it’s burning a little oil, it’s not as quick as it used to be, the transmission has a weird clunk in third, etc… nothing mechanical works forever, and yes that includes hydrogen.
Hydrogen, by the way, is the worst of both worlds… It solves a very minor issue (charging on road trips) while introducing a whole lot of new ones. The infrastructure for it is non-existent, it’s still a lot of mechanical parts (if you’re talking about the ICE version) or pretty niche technology (if you’re talking about fuel cells), it’s a nightmare to store, and it’s probably still produced from fossil fuels.
There’s a reason BEVs have caught on, and hydrogen hasn’t.
You know that fast chargers exist, right? In my car it usually takes less than 15 minutes before I’m good for another 4 hours. Charging for hours is only when I’m at home, but then I’m sleeping or something… By the time I need it again it’s full.
Batteries already last about 4 hours at highway speeds, what do you want more than that? Are you not stopping for a coffee/bite/wee/gas at some point? People say they only stop for 2 minutes to fill a gas tank, but they only count the time spent pumping gas… If you count the time spent paying, getting snacks, waiting for the bathroom to be available, etc you’re at much more than that. All that takes the same amount of time in an EV, but the car charges while you do that.
Most of these things are issues with all modern cars, not necessarily specific to EVs…
I think you’re right about there being entirely too much hype, and we’re definitely in a bubble right now, but I think this technology is here to stay. It definitely won’t have the current economic shape forever, but it’ll follow a similar trajectory to the “web 2.0”/social media tech. Is that a good thing? Probably not, but we may end up being surprised. I personally think running the models locally will end up being the best way to use AI.
The AI fad is a lot more like the Internet fad than the crypto fad. I think once the bubble pops (like the .com bubble 25 years ago) some use-cases will definitely remain. But yeah, we definitely are in a bubble.
No, it’s pretty hard to get rid of heat in space, vacuum is a very good insulator. The only way is radiation.
Yeah, my boss told he’s under pressure from upper management and customers to add AI in our app. His answer is always “to do what?”. So far, nobody has provided an answer, but whenever we get one we’ll be happy to implement it.
I don’t sit down on short (round) toilets because there is no room for my “equipment”, but otherwise I agree.
I bought one the other day that wasn’t even that, it was literally translated by Google translate. It was so bad, I had to translate the French text word-for-word into English before it made sense.
Maybe, I know Teslas are a bit power-hungry when parked.
My wife had to try charging on a 120V outlet last winter. The plug couldn’t even keep up with the battery heating requirements to actually start charging; the battery percentage was going DOWN while plugged in. It was -25°C outside though, so it’s a specific situation, but it’s actually why she had to try to charge; it’s a trip we can easily do without charging in the summer.
Then, nobody says “megagram” - it’s “ton”. So there are quirks to remember.
We absolutely should, though… That and megameters, for car mileage. We always round off to the nearest thousand kilometer anyway.
Well something about 200 kms away will take 2 hours to get there on the highway going 100 km/h…
It’s not as neat as 1 mile = 1 minute at 60mph, but it’s still pretty easy to do the mental math.
I’m 35 and my daughter is 15. When I’ll be 37, 16-year-olds will litterally be younger than my actual kid. This is all kinds of fucked up.

Saw them last year with Kamelot, it was an amazing show. I didn’t know them before but I’m a fan now!
These figures are also heavily dependent on where and how the car was manufactured, too. If the factory is powered by clean energy, doesn’t that reduce the amount of greenhouse gas emitted during manufacturing? If EV tech advances enough that the mining rigs are electric-powered, does that not also reduce the amount of GHG emitted mining lithium? Eventually we’ll also have enough batteries to recycle that too (batteries are basically a very rich lithium ore), can’t we do that in clean-powered factories?
Basically, I think the conversation on “how much manufacturing a given product pollutes” is entirely focused on the wrong thing…
Also, a lot of these studies compare an EV’s complete lifecycle with just the tailpipe emissions of an ICEV. Mining, refining and transporting gasoline has a huge carbon impact before you even put it in the car.
