  1. About 3) Can't they simply replace the whole tank with one that has a new pump ? And then fill it with hidrogen ?

  2. I can't wait for a similar analysis on the Aptera car too! Regarding the solar panels, IMO it's mostly an useless gimmick. Ok, if you REALLY like to travel in remote areas (that still have good roads somehow), then, ok, it makes sense. But that's really, really niche. Otherwise, especially since we need so many solar panels globally, to get rid of fossil fuels, any solar panel on a car is at least twice as productive sitting on a roof. Like a roof over a parking, charging the battery that some electric cars can use to recharge while the car is parked and the owner is busy. On a roof it can be 100% in sunlight (except only from clouds) and it can be oriented directly towards the sun. Or close to, if it's static. On a car, at least 1/3 of the panels are not well oriented. Well, come to think of, almost none are properly oriented, though usually most of them are almost decently so.

  3.  @taiiat0  How the hell is the range only 30-40% bigger, when towing a trailer more than double the Cybertruck's weight ? Does the empty trailer weight in 12000 pounds or something ? What am I missinig ? Shouldn't the range be increased by something like 300-500% ?

  4. You know what's best ? All that suspection magic and not once have I heard AI in that section! Which, to me, means that it's legit, not hopium BS.

  5.  @EngineeringExplained  So that means that Formula 1 is LESS than Formula 2, right ? I should watch more Formula 2... sucks when you don't know math.

  6.  @fluchtigziege3202  "batteries are kinda at their optimum, we know them for thousands of years, we know pretty much all there is to know blabla" (summed-up quote) Clearly the dumbest post of this thread. Maybe even the comment section, but I haven't read all comments. It's not like there's massive-scale research in the battery technology, which did continously improved in the last 2 centuries and continues to do so (easiest example would be the last Tesla battery day). It's not like solid-state batteries are a thing (while you state the vinegar batteries in ancient times as if they were proven). It's ok to not be excited, but to say that we pretty much know all there is to know... sheesh

  7. 11:42 The global market share for electric cars, in 2018 and 2019, was 2%. If I read that correctly, that means that the total number of electric cars in use total at 2%. But what matters is the NEW cars market share. And I have a vague feeling that it's more than 2%. In Norway, in 2019, there were more new electric cars sold that ICE cars. Sure, it's a lower percent in the rest of the world, but I wouldn't be surprized to find it to be 10-15%.

  8. EE: "We don't drive penguins" People running Gentoo Linux (or other distro): say what ? Regarding the theoretical limits, seeing that weight drop by half (maybe by simply having a smaller battery) would still be very neat. With 8kWh per 100km, a battery of 50kWh means basically 600 km range. That's pretty good. And with a less than a ton car, it should be pretty easy to handle, it should require a bit even less power, so less heat and cooling. Over time, we'll hopefully get better batteries. So, the 50 kWh becomes the norm, but the battery will weight, say, only 200 kg. On that front, I can't wait for more advanced Citroen Ami, Renault Twizy etc, really small cars, as much penguin shaped as they can be, with something like 30 kWh batteries, at, say, 500 kg the whole vehicle. For 60 to 80 kmph speed, it could get to 6kWh/100 km. So, 500 km range, which for a go-to-work-then-shopping-then-home car, it would be perfect. Charge it like once per week. Or can keep it sipping power from normal household plugs. Hell, for something like 6 kWh needed per day, it would only need about 4-8 sqm of solar panels installed in your parking lot at home, to charge a battery that the car will refill at night. Also, like others said, can't wait for the similar analysis for Aptera's car. Seemed a bit too good to be true, but it starts getting into the realms of possibility. Having the chassis itself being the heat radiator is a really neat idea.
