I was reading about CCS using PLC networking today, trying to find adapters that accept power via CCS and deliver it via ChaDemo (this involves a man-in-the-middle board, naturally).
But I would not have imagined that some company ships a product with SSH listening on an interface anyone can reach and root:root as the credentials.
I hope this is an exception, but also hope the security researchers test as many charging stations as they can.
About ten years ago, when I built my house, I decided that solar power would suffice. It did not - got a grid connection last year - but solar power is giving me the biggest part, so my grid connection is a laughable 3 x 6 amps. :)
Around 2009 or so, a fellow anarchist linked an ecological footprint calculator in a forum. I ran it, and found out that 60% of my footprint came from driving a lot (I don’t fly, except for flying drones), and most of that from buying fuel. So I built an electric moped-car. But I built it wrong and had to dismantle it, sell the metal for scrap and build another. It lasted a few years, then I was forced to switch to a temporary gas-powered microvan. When the microvan broke down, I spotted an auction: someone was selling an electric microcar which the social ministry had crashed. So I got it, managed to fix it, and finally I could produce my own fuel for driving. The road here has obviously been steep and littered with failed projects, but now I can even support other folks who drive that kind of stupidly made microcars, while I bide my time to build a proper electric moped-car.
I am working on the part of communications - not being a passive consumer but giving some and getting some in return. Found out that some folks have started experimenting with MeshCore and MeshTastic in my town, so I intend to join those nets and see if they’re usable for chatting with a friend.
I am also working on other kinds of communications (agile ultra wideband frequency hopping with SDR) but sadly, this is less solarpunk and more like miltech.
Dehydration can be done with vacuum, perhaps?
The neat thing about them:
First, the pair of habitats can be rolled by operating the cylinders as momentum wheels. If one habitat’s rotation is slightly off, the two cylinders will rotate about each other. Once the plane formed by the two axes of rotation is perpendicular in the roll axis to the orbit, then the pair of cylinders can be yawed to aim at the Sun by exerting a force between the two sunward bearings. Pushing the cylinders away from each other will cause both cylinders to gyroscopically precess, and the system will yaw in one direction, while pushing them towards each other will cause yaw in the other direction. The counter-rotating habitats have no net gyroscopic effect, and so this slight precession can continue throughout the habitat’s orbit, keeping it aimed at the Sun. This is a novel application of control moment gyroscopes.

For anyone with an interest in chemistry, I recommend the scientific paper.

Trying to think of critiques:
the wavelength of light necessary to “charge up” pyrimidone is fairly short (300 nm, UVB ultraviolet light)
the quantity of UVB light on Earth’s surface is limited (it is mostly absorbed by the ozone layer)
however, one can artificially produce ultraviolet light from solar electrical power, or figure out molecules that charge with UVA or even blue light, which would be perfect
Positive aspects:
Addition of hydrochloric acid (HCl) to Dewar pyrimidone (107 mg in 0.46 ml of water) increased the solution temperature to 100°C and induced boiling within 1 s, demonstrating rapid macroscopic heat transfer to an environmentally benign medium under ambient conditions.
Subsequently, the solution can be neutralized with an alkaline chemical, pyrimidone can be “recharged” and the cycle repeated. The summary of the article does not mention how many cycles it endures. I would be good to know that.
IMHO, with this sum, Ukraine can finance enough drone production to saturate and overwhelm Russia’s air defense regularly, and regularly bomb industries which the Russian war effort relies on, with enough drones to disable them.
It is unlikely that Russia will stop producing drones and doing the same, but starting from this summer, it will take damage to strategically important places on a weekly basis, and might run out of money to finance things.
If one looks at polls from “levada.ru”, Putin’s popularity is already dropping at a rapid rate for some months. Hopefully this will accelerate.
The remaining question is: how exactly will the war end? Hopefully with negotiations, but other scenarios are possible. It could be economic crisis, strikes and protests in Russia. Or a coup. But it could also be escalation to weapons of mass destruction. The role of Ukraine’s allies should be to deter Russia from using that last option.
This was an interesting read.
Especially his speculation that lack of a clear constitution (Basic Law was adopted as late as 1994 and is not a full-fledged constitution) and lack of clear borders contributed to Israel’s fall into the current state.
Too generous US “security assistance” certainly helped. If you can solve a problem with bombing without worrying about getting bombed, you may start thinking of war as a normal thing.
Failure to contain the populist extreme right is another stumbling block. If there had been no Netanyahu (and his corruption scandals, and the court cases awaiting him domestically, filed a considerable time before the ones awaiting abroad), things might be different.
Ultimately, I would say: Israel failed to install brakes, and failed to contain its greed for power and land. It had too much cooperation and still has too much cooperation.
I don’t know if there’s a reasonable way out.
I’m really happy that Hungarians got their wannabe president-for-life kicked out peacefully. :)
Regarding Russia - Putin’s popularity is in a clear downward dive, but a dive from very high altitude (he has built a formidable propaganda machinery and brainwashed people severely) so it will take time. His regime currently has almost full control of Internet use in Russia, so the only channels which can operate freely are VPN tunnels to services hosted abroad (Telegram being most popular). I hope self-organizing mesh networks will also offer a challenge in cities, but that remains to be seen.
Sadly, unlike Orban, Putin has also rebuilt the system so that he can order arbitrary violence (e.g. poisonings). As a result, most likely in Russia, when time comes, it will be bloody. But there’s a positive thing about Putin: he’s old and might just die one day (or touch the wrong door handle without gloves, if others near him decide he’s too old), opening an avenue for peaceful change.
Trump will be kicked out, I’m 95% sure of that. But Americans will have to rethink the role and authority of the president quite soon after that. And I mean limiting it.
If the French embassy does not manage to resolve this, given her age, sadly I think ICE will detain her to death.
Whoever snitched (it’s obvious from the article) should experience big setbacks in life.
Heyva Sor is real and if you can, I am sure they welcome any help. :)
adding they would need to build up their own nuclear capability, costing billions of euros
Billions of euros is not a big sum for nuclear weapons. If others ask politely, maybe France or the UK will give a few tips about making them cheaper. Sweden may also have some recipes in the bottom drawer of canceled stuff. Ukraine does very likely possess most of the required knowledge to recreate Soviet designs.
OP, you have just spammed the same post to 9 communities. The document you posted is from year 2016. I should note that a few things have changed since them. Iran has massacred over 1000 protesters during the Mahsa Amini rebellion. Iran has supported the Russian invasion of Ukraine. Iran has had a war with Israel (but I can’t really blame them, since escalation was mutual). And most recently, Iran has massacred what’s likely several thousand protesters during the past few days.
I should note that Iranian people, all of them, also have plans. The US isn’t the only organization on Earth with ability to plan things, and attempt to fulfill their plans.
Some ayatollahs plan to keep ruling with an iron fist, killing thousands if needed. Some leftists joined them in revolution decades ago, but were surprised to see that the ayatollahs hijacked state. Those leftists used to blow the ayatollahs up (in scores) decades ago, but had to retreat out of the country. Some king used to rule before the revolution, and surprisingly some people think the king’s son might be a suitable person for a transition government. I notice that he seems intelligent, but I don’t think he’s suitable. He’s just their best known opposition figure currently…
…but of course, talk of a transition goverment is pie in the sky fantasy as long as 12.7 mm flies on streets.
The most pressing problem is that protesters have lost over 10 000 people as prisoners (likely to be excuted as “enemies of god”) and likely several thousand as dead, while the Basij and IRGC have lost less than 100 members.
The most pressing problem is that Iranian protesters aren’t armed, don’t have explosives, don’t have decent communications and most of them don’t know how to improvise weapons, explosives and communications. As a result, they’re getting slaughtered.
There is also a secondary problem. A US president promised to protect them, and it seems they believed him. They shouldn’t have. Even if he intends to do something, they’ll be dead by that time.
I would buy it. :)
Story: I drive a Mitsubishi electric car of generation 0 (MIEV). They have a typical error: a high voltage comparator on the motor controller breaks, stopping the car. The fix involves 1 resistor, and works (you just need dwarves with titanium hands to reach the correct part in less than a whole day). The resistor costs cents. Authorized representatives propose swapping in a 5000 euro motor controller (the remaining value of the car is about 1000 euros).
Easy maintenance is an absolute requirement.
After thinking about this for a while… I can’t say I agree with that.
Sensors can fail. Some companies may even produce sub-standard sensors or faulty logic. I think it’s OK to tell people that copper and aluminum aren’t allowed on an induction top, and the makers of induction tops seem to think similarly, they just add a sentence “unless equipped with a magnetic base”.
Let’s take a manual of a randomly chosen induction cooker:
https://www.caple.co.uk/wp-content/uploads/2018/01/C850I-Instruction-manual-May-2017.pdf
Let’s examine what it says:
Cookware made from the following materials is not suitable: pure stainless steel, aluminum or copper without a magnetic base, glass, wood, porcelain, ceramic, and earthenware
On one hand, an aluminum pot won’t heat. On the other hand, aluminum foil will melt, or if placed somewhat closer, catch fire. I think I should be allowed to claim that “aluminum is forbidden” on induction tops and add that “aluminum foil is extra forbidden”.
Will you kindly restore my post? People can downvote it if they don’t like my interpretation, but I don’t think it’s misinformation. It explains some things they might not even know about. I would be sad if people think that ferromagnetism is required for induction heating to happen.
Thanks for correcting.
There seems to be contradictory information on the subject.
Aluminum foil is proven to melt on induction cookers (see attached photo). But that’s because foil is thin.
https://commons.wikimedia.org/wiki/File:Foil_on_induction_cooktop.jpg
…as for thick aluminum cookware, or copper cookware, I was not implying that they would overheat themselves, I was implying that the induction cooker would overheat its coil attempting to work with them, because they conduct current better than the coil. But perhaps that’s prevented by protection circuits. I can’t test since I don’t have an induction cooker at home.
EM-fields induce current in copper and aluminum perfectly fine, no ferromagnetism is needed. These metals simply conduct the current very well, so no heat appears. Steel and cast iron, having considerable resistance, heats up in a similar field, conducting similar amounts of current.
As an added benefit besides the environmental ones - you can’t blow out a wall and collapse a house with careless use of an induction cooker. :)
In the “smaller vehicles” part, great obstacles need to be overcome.
I would be content with doing only the parts that are reasonably economical and efficient:
Economically, this would likely make ends meet - and keep hydrogen away from consumers (consumers are careless and their systems often faulty, while hydrogen is demanding and dangerous).
If you are looking for passive alternatives, then I’ve got bad news: you have to design them before you build a house.
In Iran, before electrical power became available, they used wind towers to draw up ground-cooled air through the qanat (underground aqueduct) system. It works without external power, but you have to know you need it before you build houses.
Also, simply a house with very thick stone walls (expensive to build), a cellar (possibly with a cistern) and no south-facing windows will stay cool during summer peaks.
