Have you tried to fuel a ICE vehicle in a power outage? I waited a week in the Congo. Getting fuel out of underground tanks and paying for it are non trivial with no power. I can charge an EV off my solar panels.

And solar is just one of many ways of generating electricity. Wind turbines continue to work, as do hydroelectric plants (and on a smaller scale, water wheels). Worst case scenario, you can burn more readily accessible carbon based fuels like wood to make steam to generate power. Vehicles that are dependent on extraction and refinement of petroleum are actually quite limited in comparison.

The battery in a model X is 57,000 watts. To charge that with an 800 watt consumer grade wind turbine would take 71 hours. Try again.

My concerns are the computerization of vehicles in general. The issue is not entirely with the telemetry itself, as you frame it. My issue is "what happens when the telemetry is not available?" You, and perhaps your friend, seem to be framing the problem as though the concern is that the car is filled with "spyware." My issue is that the car is filled with "DRM" from the manufacturer. When I buy a car, I expect to ow…

In armageddon, you would run out of fuel around day 3 and then that's it. A CyberTruck will charge just fine from anything that can generate the proper AC or DC, no phoning home needed. Many home solar installations can work off grid and charge your car.

To charge a 57,000 watt tesla with an 800w consumer solar panel would take 71 hours of sunlight. There is not 24 hours of sunlight in a single day. This also is not considering the battery management which heats the battery passively. So it would take a week to charge a Tesla with equipment that you could carry inside the car.

Intent matters. Some older diesel vehicles smoke a bit. That is normal. Intentionally detuning the engine to inject massive amounts of fuel in order to induce billowing clouds of black smoke is indefensible. It is especially bad because they are not out there using this capability in innocent fun, it is specifically aimed at passersby who happen to be driving a fuel efficient vehicle or riding a bicycle. Some of us d…

It's always a lifted chromed-up truck with oversize exhaust. The one's I'm talking about are 100% intentional, and put money into it. Work pickups look distinctly different.

Work trucks are usually more along the lines of a beat up old 2006 Tacoma or a 2014 F-150 with a stripped down trim and fleet white paint. Totally different species.

You find another car and use a center punch on the gas tank. Drain it into a container and fuel whatever you want with it. You'll be charging a 57kw model X for AT LEAST an entire day using solar panels that would barely fit in the trunk.

And, ah, during a time of gas shortages, exactly which cars have gas in them just sitting around not being used, and who is going to let you do that to their car?

I can tell you’ve never actually lived this reality, you’re just making stuff up.

I had gas pumps not work due to lack of electricity (and lack of gas in the tanks) on half a dozens occasions in different countries.

You forgot to bring your pump, spotter, and nail-tipped bat. If you had those I'm sure you would have been able to fight your way through and have your go juice in no more than 15 minutes.

Not in a line of hundreds of people waiting days.

71 hours is waaaay shorter than the week I waited in the gas lineups in Congo, Sudan , Ethiopia and more.

And even after that week of waiting I was only allowed to buy 20 litres max.

That's not true. Germany has a 200-points plan on reducing the bureaucracy. At first it sounds like a joke, but actual points would be transformative if all points were done... I don't see it happening.

As an example, automatic approvals if a response is done within a deadline would be huge. I don't see that happening.

Or possibly happening, then there will be a scandal, and it will be rolled back.

Another funny trick is a "We are looking at it" response, or "The EIA doesn't use standardized language in ground water section, rework it" (EIA was made by company that specializes in that).

It's true but the regulations are hardly insurmountable. As a German you may have heard of such European manufacturers like Volkswagen, kuka and reinmetal

As a Swede I can add Saab(aeronautics, not the defunct car manufacturer), Scania, and IKEA to the list.

Far from a exhaustive list, but proof positive that manufacturing can in fact happen under European regulations.

I am confused... Why this so called Solid State Battery with 20.2 kWh can only achieve 350 km, while current battery that is used in "Charged Rimau" ( an electric motorcycle that is used in Indonesia) can achieve 200 km with only 5.4 kWh??? I expected more from a 20.2 kWh SSB, perhaps no less than 1500 km... Maybe someone here can explain why?

Yes, it is from Nordic Nano. It is nanoprinted and trivially scalable. Free of lithium, cadmium, lead, and cobalt. Uses abundant raw materials free from geopolitical constraints. https://yle.fi/a/74-20118784 Factory in Finland, started around Q3/2025. https://yle.fi/a/74-20180376 Verge Motorcycles bike with the new battery at CES, apparently at West Hall 5658.

> It is nanoprinted and trivially scalable. Nanoprinted snakeoil - infinitely scalable. Good enough to grab 3M€ public grants and some more from gullible private investors. Honestly, if they had the tiniest proof of their claims (400Wh/kg, 5min 0-100%, operating temp -30°C to 100°C, no Li/Co/Mn and somebody looking at the production and taking the output to the test) they would be absolutely drowned in money to the p…

I guess we can't really know that it's real until this guy gets hold of a whole bunch to test
