Depends on how much power they can put out. If it's 25MW, they can supply a lot of houses for an hour (somewhere in the region of 7000 I think? I may have a decimal in the wrong place. It's late.), but it's unreasonable to assume they'll put out that much power for that length of time, given the huge strain it would place on the batteries.
They don't provide that information, though. They just give theoretical capacities without context.
Same reason we're all "encouraged" to get smart meters: control. A centralised, digital currency can be locked and blocked, and restricted in where it can be spent, or how much, or by whom. Like a credit card, but with greater granularity, and now the state is cutting out the middle man and taking all the control (and profit) for itself.
The one saving grace of this mad world we inhabit, is that our rulers are so incompetent with any sort it technology that it's unlikely to be implemented in a working state, and may never be finished at all.
2.4 isn't really all that exciting.
The reason why more factors are a good thing is because you end up with fewer cases of infinitely repeating decimals. 10/3 is 3.33333... whereas 12/3 is 4. Duodecimal offers a good balance between factors and mathematical simplicity. It only gets weird a bit silly once you're dividing by 7 or 9, but 10 doesn't divide well into those either.
Now I just need to find an article that lets me ramble about replacing Pi with Tau...
The problem with the jars climate orbiter wasn't that it was using customary units; the moon landings used customary units throughout and went off without a hitch. The problem was that units were being converted between two teams and someone made a mistake in the conversion. It's a perfect demonstration of the need to standardise units across a project, rather than proof that any particular system is superior to any other.
We should all be using duodecimal, anyway. 12 mm to the douximetre, 120 doux to the metre, and so on. More factors.
For things like iron and nickel, yes. To a degree. The real point is that space has a functionally infinite supply, at least in the near term, and few environmental issues to get in the way of harvesting the materials. There are also potential, novel microgravity fabrication techniques to explore, as well as gaining the ability to construct much larger structures in space than we could ever hope to launch from the surface.
Twitter did nothing about daesh and other islamist-terorist accounts for years, some of which were verified under the old system, and even appeared to be tacitly supporting them by rejecting reports of obvious calls to violence and other breaches of the twitter TOS at the time. Really, what's changed now? A representative of the current (oppressive) government of Afghanistan has a verified account, but now the Musky one is in charge while it's happening, so it's all hands to the gun deck I guess.
I've got an article that conveniently contains links to both proposals right here.
I should have linked it before. It's friday. :)
The FAA thinks pilots are spending too much time relying on automation, reducing their manual skill and familiarity with their aircraft and increasing the possibility of unchallenged controlled flight into terrain because they trusted the automation. The EASA has taken the reverse position, calling for more automation and less manual control, in order to reduce the possibility of pilot error. Interesting clash up ahead.
Per wiki, so a pinch of salt is required, the typical efficiency of a grid-scale power station is also around 33%. This is before factoring in conversion losses between the grid and the car. Wind turbines, when they're actually turning (rather than sitting idle because there's no/too much wind), have a maximum efficiency of around 55%, but they will be typically less than that. This is comparable with a diesel engine, but again, this doesn't account for conversion losses at the charging point, which is typically around 20%.
The final and key point with BEVs is energy density. In short, it's terrible, and it's unlikely to improve without a fundamental change in our understanding of physics. That much-touted efficiency of electric cars is absolutely necessary, in order to get even a remotely reasonable range out of the battery. The moment you place any unexpected constraints on the car, be it towing, cold weather, slightly deflated tyres, too-strong a headwind or what have you, that efficiency just about disappears and you go from having just about enough range to make it to your destination, to being stuck between services on a "smart" section of the M6.
Which, in turn, would require near-doubling the amount of energy production in order to both charge the storage and also meet regular demand. This is just one of many reasons why grid-scale battery storage is a stupid, stupid idea. It's only touted because of the need to compensate for the unreliable nature of wind and the fact that solar (already a poor proposition in the UK) supplies at about a third of its nominal capacity when demand is highest.
We use both. Legally, all of our units are defined in metric, but any law or signage referring to distances still has to be written in miles, feet, and inches. All of our building materials are metric. Most tape measures use inches on one side and centimetres on the other.
It works. Why force the issue?
You know that "bonfire of laws" the Tory government promised us ? Where do you think the truck acts are on that ?
Nowhere, because they promised a bonfire of EU regulations. The truck acts all predate even the coal and steel union. They were superceded by the wages act 1986, per your own source. The act also predates any EU regulations regarding working time and wages.
Scaremongering does not serve you well.
If all that systemd did was replace the init with a bunch of nifty tools, it would be tolerated. It doesn't need to take over logging, cron, device management, DNS, hostname provision, network management, interprocess communications, home directory management, ntp, container management, and everything else poettering sets his sights on.
And don't reply with any variation of "it's modular". The modules are all non-trivially interlinked, with core system components such, as udev, now being so deeply tied to systemd that they cannot be used independently.
