I live in Switzerland where these are available. A Cowa 58 [0] costs CHF 4692 [1] and stores up to 13.5kWh. If you're heating the water with a heat pump, that's ~6kWh of electricity, so ~CHF 782/kWh.
I'm in the process of installing a 33kWh battery and the battery + inverter cost CHF 13600 in total for just the hardware, so ~CHF 482/kWh.
If you add solar panels, the inverter does double-duty producing AC from both the battery and the panels. The battery does double-duty producing both hot water and allowing you to use solar energy outside the times when the sun is shining.
That said, having ordered a heat pump recently and being in the process of having solar + batteries installed, the amount of electrical work needed for the solar/battery install is substantially higher than was needed for the heat pump and here, the labour costs quite a lot, pushing the upfront cost difference even higher.
I think that's where these heat storage things fit in: they have a much lower upfront cost. No matter how cheap the battery, for it to be useful in a Swiss residence, it needs to output a substantial amount of 3-phase power (3-phase is standard here, even in most apartments), which means you need to spend a couple thousand Francs on an inverter and electrical work. These heat storage devices are quite cheap and don't even need someone qualified to handle refrigerants, I imagine they could be installed by a normal plumber.
That reduced upfront cost makes them far more accessible than electrical batteries, at least for now.
I don't know what it's like where you're living but here in Switzerland it's completely normal to have one heat pump that does both. Here there's a lot of floor heating, which also uses water, so you usually just run one loop to the "boiler" (a water tank with a copper loop for the water from the heat pump to circulate through) and one through the floor and have a valve to switch which is running through the heat pump.
I got it in October so most of the time I've had it has been <10C. It's produced 806.3 kWh of heating for hot water and 6587.2 kWh for the floor heating. It consumed 302.7 kWh and 1801.4 kWh respectively, for a COP of 2.66 and 3.66.
That's a different kettle of fish entirely, largely because with the heat pump water heater they're pulling the heat from the inside of your house, forcing you to move it twice when it is cold out. With a combined unit you only move it once, as the other side of the unit is outside.
That's why they're so great for warm climates though. The water heater also cools your house, especially as that heat is then lost down the drain. Everybody in the south should be jumping on these.
FWIW, the incumbent ISP in Switzerland, Swisscom, tried to roll out XGS-PON but our "Internode", Init7, fought them in court on the grounds that it was anticompetitive, since it locks every provider into a single technology. They won.
Now customers can choose. Nearly every ISP chooses the easy way and has the customer connect through Swisscom's XGS-PON but Init7 in particular has instead built out their own routers in POPs around Switzerland so that customers can have a physical fibre directly to their network. It's just plain ethernet with DHCP so you can use whatever equipment you want. It's also allowed Init7 to do something none of the other providers can do: offer 25Gbps symmetric service at no extra cost (beyond a one-off installation cost for the more expensive SFP modules).
I haven't had to find a charger or think about them in over a year. I just plug it in when I get home and I'm done.
I did a ~10000km road trip around western Europe and while I started with ABRP, I switched to just driving normally and stopping at an EV charger when I was below around 20% and happened to see a sign.
I'm not saying this is the case everywhere, I opted for an ICE engine when I visited Australia for example. "Half the utility of normal cars" is utter nonsense in my experience though.
The thing is, if you just plug in when you get home, you likely drive very few miles. Id be for a $10k brand new EV with 100 miles of realistic range (i.e not having to keep speed below x). These don't exist. You pay for higher range in even cheapest EV, so you are paying for utility that you don't use most of the time.
There aren’t any new gas cars for sale at that price point…
And if it’s sitting at home for 14 hours per day, a normal 120V outlet will get you 70 miles of charge. That’s fine for most commutes, but if you actually need more than that, you can use a dryer outlet that gets you like 4x that charging rate (280 miles of range over that 14 hour charge). Or installing a proper wall charger will get you twice that again, but it’s really not necessary.
>There aren’t any new gas cars for sale at that price point
Yes, because a modern gas engine that makes a measly 112 hp is still a very complex piece of machinery that requires a lot of precision manufacturing and assembly.
An EV is dead simple by comparison. To make a 100 mile range ev, you don't need fancy motors. Industrial AC motors will work.
And as for charging, this requires you to be at your house every few days. If thats your average use case, you don't need high mileage EVs.
I guess, what's the general breakdown of cost between engine and the rest of the car, and the amortized R&D?
Most commuters use it mostly for commuting, but also day trips, and 100 miles is really cutting it close for day trip round trips in a lot of US metro areas.
The page only lists 126 cities, with the bottom three having an AQI of 0.
So the editorialized title is incorrect. It's not "top 5 worst air quality worldwide", it's only top 5 in this list, which is a small subset of the world's cities.
It's a Swiss company but even Switzerland's largest city, Zürich, is missing.
China sure as hell has more than 8 cities and Russia more than 2.
I have 25Gbps from Init7 at home. My "router" is a Minisforum MS-01 with a second-hand Mellanox ConnectX-5, running VyOS.
My main home server is a Supermicro SYS-510D-4C-FN6P. It has dual 25Gbps ports onboard but also an Intel E810-XXVDA4T with another 4x25Gbps ports.
Both of them are perfectly capable of saturating their ports using stock forwarding on Linux, no DPDK, VPP, anything, without breaking a sweat. Both of them were substantially cheaper than the machine in the article.
Is there something I'm missing? Why does this workstation need a ~$1000 motherboard and a ~$1000 Xeon CPU? Those two components alone cost more than either of my computers and seem like severe overkill.
Does not look like it [1]. It appears to be a protocol that enumerates your exact path, interface by interface, on every data packet. So you can just blindly forward to the next hop written in the packet itself.
By my guess, a competent and efficient implementation should be able to run the routing logic at ~30-100 million packets per second per core. That would be ~300-1,000 Gb/s per core, so you would bottleneck on your memory bandwidth if you have even a single copy.
"SCION OSS border router performance reached a ceiling of around 400k-500k packets per second, which is roughly equivalent to 5-6 Gbit/s at a 1500-byte MTU." vs. 1.4 M PPS for IP (on an older CPU) https://toonk.io/linux-kernel-and-measuring-network-throughp...
> Is there something I'm missing? Why does this workstation need a ~$1000 motherboard and a ~$1000 Xeon CPU? Those two components alone cost more than either of my computers and seem like severe overkill.
Yes, as stated in the article, it probably could have been cheaper. But this setup is supposed to:
1. Run simulations and benchmarks of/on entire SCION topologies with multiple ASes.
2. Potentially grow beyond 25 Gbit/s into the 200 Gbit/s ranges (and more?).
3. Be available to me ASAP (can't wait months for it to arrive from China).
4. Potentially be used for CI/CD performance regression testing in the future.
The budget allowed a bit of headroom for the future.
In defence of young people, it's "determined" by the people who actually go out and vote the same way a child "determines" what's for dinner when asked "would you like broccoli or brussels sprouts?"
American democracy is broken. Not in an abstract, hand-wavy feelings way but a hard, numerical, mathematical way. A two party system results in no real choice. First past the post results in a two party system. America uses first past the post. Therefore, Amercian democracy gives voters no real choice.
Margins in recent elections have been thin enough that higher voter turnout among young generations could have easily changed the outcome.
Blaming broken democracy is just a cop out. Youth voter turnout for primary elections, where there are many candidates, is also low. More parties isn’t going to change anything.
You're missing the point. There were only two possible outcomes: Democrats or Republicans. Both were bad and unappealing. Both are too dependent on the status quo to serve as vehicles for real change (so primaries are pointless too).
"More parties", through elimination of first past the post, absolutely changes things. It allows you to vote for someone who truly represents you and your interests without "throwing away" your vote. That's impossible today.
> There were only two possible outcomes: Democrats or Republicans
This is the civic illiteracy a higher comment refers to. Beyond the primaries, there are numerous down-ballot initiatives that don't tend to cleanly sort along party lines.
Democrats continue to offer up horrible candidates, and their idiotic primary system confirms those horrible candidates every 4 years. A slice of cheese could have beaten Trump, but somehow the DNC managed to offer up the most boring, milquetoast, unlikable, uncharismatic, centrist candidates they could find and beat him once out of three times. They're just kicking own-goals over and over, and they're not learning which direction to run down the field.
His policies were tempered, image-wise and often in substance, by his affinity for Joe Manchin alongside his disdain for Bernie Sanders. Balanced alongside the middle eastern foreign policy, he comes across as centrist despite the BBB.
Look up the build back better act that Biden proposed and tell me if you think that was centrist. It originally proposed extending the child tax credit (basically basic income for people with kids).
The Inflation Reduction Act, the negotiated paired down version was still the biggest climate bill in history.
He also attempted to cancel 10 to 20k each of student debt, a progressive priority. That was blocked by the Supreme court.
The list goes on.
If the electorate had given Biden a bigger majority in Congress he would have passed much more progressive legislation.
The self reinforcing prophecy of “somebody else’s job”.
It’s the job of politicians to pander to us, the good voter. Since they didn’t offer us something good, we didn’t vote, and that results in this current situation.
Politics is not my job, being aware of how politics works is not my job. My job is just to let them know they aren’t good enough. It’s because they aren’t good enough, that we landed up in this situation.
I use GrapheneOS in Switzerland and am yet to find a bank or financial app that doesn't work. ZKB, UBS, Cembra, BEKB, SGKB, WIR, N26, Revolut, debiX+, SaxoTrader, Swisscard, various TWINT apps, YAPEAL and Yuh are all installed on my phone right now and all work. Most of them don't use the Play Integrity API at all and the few that do are satisfied with the minimal level that's satisfied by GrapheneOS.
The catch is that you need Google Play Services installed and for many, you need to disable GrapheneOS' "Secure App Spawning" feature, which often trips root detection heuristics.
I know many Russians living here and when sanctions came in, their accounts became unable to receive deposits until they provided evidence of a valid residence permit. Some have problems during permit renewals as well but overall, it's nothing like as bad as it is for Americans.
Are all of these apps only available through Google's Play Store repo, or are any of the available as an apk file directly from the bank's site? For some reason most companies only distribute their apps through Google and Apple's repos. People shouldn't have to have an account with and agree to a third party US company's ToS just to download a banking app.
Why are Google Play Services required?
Genuine questions - I'm not from Switzerland and I don't have a Google account.
They're only available through Google Play. That's near-universal for commercial apps.
Google Play Services, among other things, is the main way to get notifications and location on Android, so any app that uses either of those things tends not to function if it's missing.
For what it's worth, this is entirely a carrier problem and has little to do with the technology.
Various people and the article have outlined some bad experiences but to give a contrasting example: Digital Republic, a local MVNO here in Switzerland, allows you to replace your eSIM by simply logging into their web portal with TOTP-based 2FA and clicking a button. No SMS, no contact with support, no reidentification.
The flaw with the technology is that it is designed so you need the co-operation of your carrier, when previously you did not. Indeed, for the first versions moving a sim profile could not even be initiated independently by a user, but required them to contact support. Now there is the "device change" protocol which can be triggered by an app on the phone, but I think it still requires the co-operation of carrier servers.
> Now there is the "device change" protocol which can be triggered by an app on the phone, but I think it still requires the co-operation of carrier servers.
And it won't work if your phone is broken, while a regular SIM could still easily be removed.
This is especially bad in the US, where the government doesn't like to force companies to implement consumer-friendly laws. It was such a great thing when GSM SIMs were introduced, to avoid the carrier lock that was so common in the early days of cell phones.
I only have experience with two carriers in NL and they’re the exact opposite.
No QR code, only an iOS app which needs to be installed on the phone using the plan. My mum was visiting from abroad once and I had to download the app on her phone — which required me to first log into the App Store with my Dutch account.
