Heat pump water heaters already exist. These are hybrid things where a traditional electric water heater is fitted with a heat pump. The heat pump can increase the water temp but cannot deliver enough, so heating elements are still needed to reach a usable temp.

I’m wondering if that design can be improved on this way: instead of powering the heat pump from the wall, the heat pump can be connected directly to a PV. I think that would be more efficient and cheaper because PV output is not normally directly usable. IIUC, it’s variable D/C which must be regulated and/or inverted to A/C involving more hardware, conversion, and waste. But exceptionally, I’ve heard that a PV can directly power a compressor with no middleware. Any reasons this would be infeasible or uninteresting?

Of course the tank still needs wall power for the heating elements, but would use less wall power and entail less conversion loss.

Some large PVs for rooftops were at a street market for €35 each. I’m not deeply knowledgable about them.. I just know that there are two varieties of solar panels and that the kind that are used from small appliances (e.g. calculators, speakers, lawn lights, etc) are junk. And that junk variety is sometimes used in large rooftop panels. What I was looking at resembled the kind I see on a bluetooth speaker with a slight blue tint so I was skeptical. The info on the backside of the panel indicated “1000 V”. The other thing is, all solar panels degrade over time and reach end of life after like 15 years (though this is improving). They may have been a good deal but I passed on them because I didn’t want to buy them on a blind risk.

How would I know how much life a used PV has left? Would a volt meter give that info, assuming it’s sunny when I encounter them again?

The trend in western Europe is banks are pulling out of the ATM business and joining consortiums. Then those consortiums deploy much fewer ATMs than the banks had. And they monopolise. If one or two ATM brands reject your card, you may be fucked if it’s a small city, as I recently experienced.

ATM alternatives are becoming increasingly essential due to ATM enshitification & sparcity. Some shops give cash back, where you have more money pulled from your bank and the cashier gives you cash from the register. The US has always been on-the-ball with cash back, even though the ATMs in the US are not the shit-show that we see in Europe lately.

So it’s easy to find cash back options in the US because there are several compiled lists showing various stores and limits, like this. Some shops have a fee and some not and the range of limits vary wildly. But at least there are published options.

I’m struggling to find information like that in Europe. In part this is because “cash back” is an overloaded term that also means rebate deals (like discounts of ~1—5%), so search results are polluted. It’s bizarre there is so little info about this. So many people have become cashless that hardly anyone even notices the shit show that ATMs have become. Hence low demand for info on cash back options.

Cash back can be interesting for foreign card holders in Europe because they avoid ATM fees. Discovercard/Diner’s Club seems to guarantee no cash back fee and at the same time no currency exchange markup. But the data on cashback in Europe is sparse and inconsistent from one country to the next.

• Norway shops offering cash back refuse non-Norwegian cards.
• UK stores require no purchase and have no fee, but they also discriminate against non-local bank cards.
• Denmark: local cards only, credit cards refused.
• Spain: no cash back service (but that article is 10 yrs old).
• Netherlands: rumour is that Albert Heijn, SPAR, and Smullers have cash back. (SPAR advertises cashback on their UK site with a locator because apparently only some locations offer it. Yet they wholly conceal this option from their Dutch website)
• Belgium: Aldi has it. But if you boycott Israel then you boycott Aldi North (all Belgian Aldis are Aldi North)

Mastercard has a “cashback store locator” on their US website. And apparently that db is only populated with US stores. Which is a bit shitty because MC is global and they should have that information.

I’m not getting why shops are non-transparent about this. Presumably they offer cash back potentially fee-free because they profit from whatever you’re buying. It would work on me.. if I have some confidence that I can get €200 cash back at a store, that store is sure to get my business.

Anyway, please feel free to use this thread to crowdsource cashback info.

The EU has quietly imposed cash limits EU-wide:

• €3k limit on anonymous payments
• €10k limit regardless (link which also lists state-by-state limits).

From the jailed¹ article:

An EU-wide maximum limit of €10 000 is set for cash payments, which will make it harder for criminals to launder dirty money.

It will also strip dignity and autonomy from non-criminal adults, you nannying assholes!

In addition, according to the provisional agreement, obliged entities will need to identify and verify the identity of a person who carries out an occasional transaction in cash between €3 000 and €10 000.

The hunt for “money launderers” and “terrorists” is not likely meaningfully facilitated by depriving the privacy of people involved in small €3k transactions. It’s a bogus excuse for empowering a police surveillance state. It’s a shame how quietly this apparently happened. No news or chatter about it.

¹ the EU’s own website is an exclusive privacy-abusing Cloudflare site inaccessible several demographics of people. Sad that we need to rely on the website of a US library to get equitable access to official EU communication.

update

The Pirate party’s reaction is spot on. They also point out that cryptocurrency is affected. Which in the end amounts to forced banking.

There are now two BifL communities in the free decentralized world:

• !buyitforlife@slrpnk.net
• !buyitforlife@discuss.tchncs.de

Perhaps each wants to mention the other in the sidebar?

Most people are unwilling to change their lifestyle significantly in the face of climate catastrophe. In particular:

• refusal to alter their diet
• refusal to ditch their car

Even the idea of simply stopping livestock subsidies is fiercely fought because people would still consider an absence of intervention to be lifestyle intereference. People are hostile toward the idea of changing their commuting and teleworking habits. In the democratic stronghold in California, even democrats voted out a democrat who tried to impose a fuel tax because they are resistant to giving up their car. Examples are endless.

the dominant excuse→ “carbon footprint is a BP invention”

The high-level abstract principle that underpins resistance to taking individual actions is the idea that because the “carbon footprint” was coined by BP in an effort to shift blame, people think (irrationally) that the wise counter move is to not take individual action. Of course this broken logic gives the oil companies exactly what they want: inaction. This has become the dominant excuse people use for not changing their lifestyle.

psilocybin

The deep psychology surrounding the problem is cognitive rigidity-- unwillingness of people to adjust their lifestyles. So how do you make people more open-minded and increase their psychological flexibility? One mechanism is psilocybin, which has been shown induce neuroplasticity and free people from stubborn thinking. It’s a long article but the relevant bit is this:

Other studies have shown increased neuroplasticity through meditation. In any case, we could use a less stubborn population.

Not just for climate, but consider the pandemic where conservatives (by definition the champions of stubbornness) refused to make even the slightest lifestyle change and fought every act of remediation. A population with a higher degree of psychological flexibility would be better to react to changes of any kind.

Asking the gov to proactively shrink or limit animal products is a non-starter because there are just too many (voting) consumers who would be outraged. It would be political suicide. Same for cars. Forcing car owners out of cars would be political suicide as well.

But what I find baffling is there seems to be no chatter about the fact that the US gov gives (millions?) in subsidies to livestock farmers. And Europe gives tax breaks for “commercial” cars (mischaracterized personal cars). If the gov were to end the subsidies, there could be no reasonable complaint that the gov is interfering. Because in fact the gov would be ending their intervention.

Germany is struggling to get people on-board with a green energy movement that involves banning high footprint domestic heating systems (e.g. gas boilers)-- thus forcing people to migrate to heat pumps. A low-income family who was interviewed said it would cost €45k to install a heat pump in their terraced home in Bremen.

That price tag sounds unreal. I am baffled. What’s going on here? I guess I would assume an old terraced German home would likely have wall radiators that circulate hot water. Is the problem that a heat pump can’t generate enough heat to bring water to ~60°C, which would then force them to add a forced-air ducting infrastructure? Any guesses?

(note the link goes to a BBC program that looks unrelated, but at the end of the show they switch to this issue in Germany. I’m not sure if that show is accessible.. I see no download link but that could be a browser issue)

Consumerism is part of the climate problem and perhaps more so a waste disposal problem. Consumerism probably cannot be stopped but it can be reduced. It’s disturbing in the current climate that #BlackFriday still exists. To encourage the kick-off of mass consumption a month before Christmas likely does a lot damage.

I suppose cancelling Black Friday would be impossible in the US (where I suspect it started). A large number of democrats would oppose it and probably every single republican in the US would fight to their death an anti-consumerism action like that.

But what about Europe? Doesn’t Belgium and Netherlands restrict store-wide sales to just two weeks or so out of the year? For Europe, perhaps instead of cancelling it (which many would view as over-interventionist) they could double the VAT rates on that day on clothes and electronics. IDK.. that’s probably crazy talk. Ideas welcome. There’s no real issue with sales on services, but consumption of goods is where the damage is done.

I hate the idea that one of the most environmentally reckless companies in the world (#Amazon) gets a huge boost in sales on Black Friday. It makes the day depressing to see the masses rush to enrich a company they should be boycotting all year. I loved Black Friday back in the days when I was a loose cannon consumerist myself. Now it’s just a shit day where I deliberately avoid shops in order to not support it.

UPDATE

To be clear, I would not propose cancelling the unofficial holiday US employers often give on Black Friday. Just the sales.

A new bike has been recently introduced which is designed with the goals of products in the 1960s-- rugged, simple, built to last. Nothing is flimsy on this bike. Even the fenders and sprockets are thick. The design focus was two main goals: robustness and simplicity so owners can fix it themselves. The gears are internal, which seems to reflect ruggedness being prioritized over self-repairability. Derailers are inherently fragile and cassettes wear down relatively quickly and also would impose a thin chain. The internal gears enable the chain to be thick and wide.

The website is in French but I machine-translated the “about” section:

A Bruxellois, magnet to travel by bicycle in town, activist in several environmental associations and working in the design and manufacture of cycles since 2014, established the SUGG srl in 2021 to provide simple, solid, practical, fast, fun, designed and assembled bicycles in Brussels with high quality components often produced in Europe.

The SUGG bikes are aimed at young people from 9 to 99 years of age who wish to move by bike without assistance and prefer to exploit the powerful resources often ignored whose nature has given them. Indeed, with no electric assistance, SUGG bikes are more economical, light, ecological, simple, reliable, durable and fun. At SUGG, the efficiency and ascent qualities of the bike are optimized by the choice of geometry and components. It's fun!

A few objectives of SUGG: to contribute to the improvement of life in our cities thanks to less air and noise pollution, calm and friendly streets, intelligent and respectful traffic, efficient, beautiful and funny movements; to participate in the fight against unemployment in our regions, on the one hand by repatriating the design and assembly in us and on the other hand by procuring the parts with manufacturers not too far away from us

I don’t have one myself but if I wanted a bomb-proof bike that would last my whole life, this is probably what I would get.

Sometimes I report a bug & the dev starts off asking for more details. But then there’s a kind of scope of effort creep where you start to realize you’re being tricked into finding where in the code the problem is so you can fix the bug.

It’s a bit of social engineering of sorts. When I post a bug, I do that from the back seat of the car. And it’s like the dev sits in the backseat as well while coercing me into the front seat. So sometimes there’s a bit of weasel words and nuances with sneaky wording that needs to be deployed in order to stay in the backseat while trying to get the dev into the front seat where they belong!
