Those are often the first things to be electrified, because the operators are closer to rational actors who see the immediate savings. Of course the real world gets in the way, but for example about half the busses here are electric because one of the companies replaced them all as part of a fleet upgrade a couple of years ago. They are much nicer too.

Submission + - Ukraine's issues with Starlink were caused by Ukraine (x.com)

An anonymous reader writes: Starlink terminals disconnected at speeds above 160 KPH, as determined by the Starlink terminals internal GPS.

To get around this, Ukraine hacked the Starlink terminals to think they were stationary regardless of speed.

SpaceX figured this out, and updated the system software to detect excessive speed by seeing how rapidly the terminal switched from on satellite to another. This broke Ukraine's hack, and Starlink would no longer work at high speeds.

Ukraine was using Starlink in a way that violated the terms of service.

Starlink figured it out and stopped it.

Michaux has been widely discredited. His 2021 report, for example, listed 65.4% of energy as wasted. That's probably true, most fossil fuel powered systems produce massive amounts of waste heat. But he still seems to think that we need to produce that much if we switch to electricity, which is obviously not the case.

Some of it is just misrepresentation. He uses Germany as an example, claiming they need 12 weeks of energy storage. The estimate he cites, which was already outlandish, actually says 24 days, and that's ridiculous. In the real world, there is no need for a whole country UPS because with enough renewables you only ever see hours of deficit, which can be covered with gas (only because it's cheaper to do that and offset it than to go 100% renewables/storage).

He also ignores all the HVDC lines that were being built at the time, and hasn't updated for all the once built since or announced since, so his estimate for the battery storage requirement is at least an order of magnitude off. He also bases his mineral estimates on old chemistry that was poor even when he wrote it, let alone today, and assumes it all has to be lithium ion battery storage.

He does the same thing with copper. Bases it off old technology, ignores aluminium as a conductor, ignores recycling, and vastly over-estimates the requirement.

The whole thing is full of obvious holes. Reality is that most countries can get to over 95% renewables + storage, and then some other sources for the remaining few percent which can have carbon capture and offsetting to reach net zero. The result is cheaper energy and a small chance we might not completely bugger up the planet.

Not that we shouldn't do that sort of thing, but to have any chance of this not being an absolute shit-show that causes an unprecedented global disaster, we need to do a hell of a lot more than just plant trees.

Basically everyone needs to do what China is doing in terms of renewables and storage build-out. The scale is unimaginable for most of us in the West. The biggest projects we ever did are tiny in comparison.

That's very doable with current EVs. In fact about a decade ago Bjorn Nyland used to tow a trailer that size in the middle of the Norwegian winter, with an old Tesla.

A few hours journey is no problem, even in cheap EVs. Here, for under the equivalent of $25k before tax, you can get an MG that will do 3 hours of non-stop driving at motorway speeds. I've done it in March, in the rain and the dark. It's only when you push out to 5 hours that you need to stop and charge, but personally I need a comfort break anyway.

As more people get EVs, other people start to realize that they will work for them. They work for almost everyone, except for people with *very* unusual and special requirements. As for used, the situation isn't ideal at the moment, but here the standard is an 8 year battery warranty and repairs/replacements after that period are possible, so it's on a par with buying a fossil. Actually probably slightly better, as there are some really unreliable combustion engines on the market. JLR is notorious for them.
