Comment Rocket stove (Score 1) 108

I'm not going to critique the fine article directly, but wood is a much more renewable source of energy than fossil fuels or even nuclear. If you have some land around your house, you are probably also not very dependent on logistics supply chains.

There are some stove designs (typically under the name of rocket stove) that have been developed to provide nearly complete combustion. Hence, they can be fed with pruned twigs and shoots - no need to grow mature trees, fell them, and split the logs - or wood chip pellets made from waste. Let me restate that: Because they are so efficient, they use a lot less wood than the conventional fireplaces and wood stoves people are used to, leave much less ash residue - and also conceivably release a related lower concentration of lead. Some of these designs employ piping the exhaust through considerable thermal mass to capture most heat, and the exhaust is virtually odorless. One enterprising fellow heated a tipee in Montana or somewhere in winter (yes, only a sheet of canvas between indoor shirtsleeves temperatures and outside snow).

Unfortunately it seems it is human to get stuck in "old ways" - e.g. old heating methods, and not knowing or accepting there are better ways EVEN for the same fuel. Another example is building codes (in my non-USA locale) that used to be still adequate for when heating was cheap. On the other hand I guess I can be glad that I live in a more temperate climate where it seldom goes below freezing, so often some layers of clothing are sufficient.

I recognize none of those names - producers, actors, etc. (apart from the Cavil guy, but as TFS says, he's also a bit old now). But what the heck, the last time I saw a feature of any kind may have been 2020 or so ("some" digital medium, due to C19).

I guess the same thrills that made ol 'doppio zero so attractive to schoolboy me will still be in play in new installments, so I'll give it a pass again.

Comment Re:Just pull the trigger (Score 1) 50

Not disagreeing, but there are some nuances.

paper/cardboard

I maintain a ("warm") compost pile, and also an earthworm farm. A lot of the wood pulp-based packaging I have goes to them: egg cartons (made from recycled paper), air fryer liners (marked compostable), used paper towels and tissues, corrugated cardboard boxes, etc. There's a couple of problems though: some items (e.g. take away coffee cups, milk cartons) are made waterproof with a plastic lining. Packaging may be coated with a high-gloss surface finish for attractiveness, or a lot of inks of unknown content. Even brown boxes have stickers and tape on them that are not compostable and are hard to remove. So a lot of these paper-based packaging is still not compostable and does not solve the problem (the same "contaminants" also make them difficult/costly/impossible to recycle).

Glass

Almost all of the wine, beer, olive oil, vinegar, pickle jars, and other glass containers that have gone through my kitchen have labels on them that are pretty hard to remove with only warm water and soap (although a few are easy). Not sure how much of a problem that is at the recyclers. The collection points I use for glass state nothing about labels, only the type of glass to be accepted (typically only bottles). Guess it would be much less energy-intensive to clean and sterilize bottles, re-fill them, and stick a new label on, as compared to melt them back down.

Thanks for the list - and doing the originally linked article's job for them.

What is interesting to me is that there are also countries here that produce oil (e.g. Nigeria, Angola, Norway, Canada), and for some of which at least, their oil industry is presumably a major part of their national GDP (I'm too lazy to look up the numbers right now.)

Comment Re:But why? (Score 1) 92

Creating vermicompost on the moon may be close to impossible, so importing it would always be necessary.

The physical difference in regolith from earths soil is that it is unweathered and has very sharp shards and edges that would literally tear up the internals of any worms that might try to ingest it. Without the worms there would be no future vermicompost, so the system can not be self sustainable unless they first process the regolith to remove all the microscopic sharp edges.

You seem to be not too familiar with earthworm farming, but fact they DON'T need soil (or regolith) where they are living, breeding, digesting, and producing castings (= "worm poop"). And you don't need the worms present when you harvest the castings to transfer to your growing medium - the microorganisms in the castings is what you are after, and they do the symbiotic work with the plants (as with the humus from the original article). In fact, the typical earthworm species (Eisenia foetedia) that is most often used due to being a prolific composter, does not survive in your vegetable garden that well, since it is a species from the leaf litter in European forests. They are better off staying in the worm farm, to digest more organic material, and breed more little wrigglers.

Source: the plastic bin containing vegetable peelings, carton, and other organic materials, next to my fridge, that the earthworms seem to be thriving in. I did add some crushed eggshells to it (apparently some roughage like that is nice for them, but optional). While these shell fragments do have some sharp edges, this is probably not comparable to regolith (of which I don't have any readily at hand to test on the worms).

Comment But why? (Score 3, Interesting) 92

It's good that they do these experiments, as it shows risks regarding heavy metal toxicity.

Vermicompost obviously contains lots of earth microorganisms that live in symbiosis ("living together") with plants here on earth - getting nutrients from plants (mostly carbs produced via photosynthesis, light not being available under the soil) and also supplying nutrients (nitrogen, minerals etc. from inert soil, converted to a bio-available form that plants can utilize) and even water. No surprise here, foodweb is a known concept by now with many people interested in this.

But I don't know that it would be the most practical to ship vermicompost from earth in large and continuing quantities. It might be better to initially ship the earthworms themselves (or at least their eggs) as well as (organic) foodstuffs for the humans there. This could then serve to ramp up a growing population of earthworms on the moon. Should be obvious though that this will be in a sheltered environment, not on the exposed raw lunar surface - like with earth-origin humans and their earth-origin-crop plants. This would be a live ecosystem being constructed from the ground up, protected from a hostile environment - not inert or sterilized materials.

Having a colony of earthworms would allow the setup of a vermiponics system (~"aquaponics" using worm casting nutrients instead of dissolved salts) for growing food plants, using some inert substrate for a physical support structure for the plants - no dependence on a possibly toxic growth medium. Potatoes and other root crops are successfully grown here on earth, together with the customary leaf and fruit crops. After the food has been eaten and the waste passed out again, the worms can come into play again, to convert this back into compost, as has been done successfully here on earth with multiple wet or dry vermicomposting toilet systems.

One drawback with vermicomposting is the amount of time it may take - much less of a problem here on earth if you've got some space and a friendly environment. (This is one site I found via websearch that was quite interesting regarding construction, ramp-up and maintenance here on earth, gives some feel of what could be possible.)

Ironic that these little miracle workers considered for the moon are named "earth"worms.

I'm interested how the difference in gravity would influence them.

Comment How about also catering for niches? (Score 1) 384

"Gas-guzzler revival" - if a headline starts with hyperbole (no matter your own previously held opinion), you already know it is meant to influence, not inform. As most media these days and for a long time already. (Which increasingly causes the opposite reaction than what they hope for.) Anyhow, that off-topic rant over, what I wanted to say is:

I am not an American nor a fan of american cars. My first car, bought at the end of the last millennium, when I was young and "adventurous", however was a big 3 liter diesel truck (Toyota). Way back then I thought this will probably be my last fossil fuel vehicle, the next one would probably be electric by the hype in the media back then. And I was looking forward to the new tech, it looked exciting and promising. (I also was an early adopter of digital photography, for instance.) Exactly 20 years later I felt it was really time to replace the truck, since keeping it in good repair became more and more difficult and costly. EVs were still not a good, reliable option 7 years ago (in my locale), so again I got an ICE - a more comfortable "crossover", almost exactly what would have been termed an "estate/station wagon" 30 years ago. Went for the model with the best (claimed) mileage. It still has sufficient cargo space and ground clearance for those weekend camping/hiking trips, so a good replacement for the truck, but a little less "robust" - wouldn't take it off the gravel path. It is also wider, with less driver visibility, than the truck, and thus more difficult to park at the shopping mall or in my garage (ironic). When bought, I again had the thought that this might be my last non-EV transport. A little less enthusiastic thought.

I have a young friend who gets a lot of cars to review, in the short-video format that seems to flood social media these days. I get to experience some of them first hand, including premium chinese models. Very nice. Quality feel, lots of features, good driving experience. Constantly looking for a charger (hehe).

But that made me really rethink what I want in a car. I want independence. I do not want to buy constant subscriptions, or have to replace the vehicle every 3 years or so (my own hyperbole) due to planned obsolescence, or be monetized in some other way still to be dreamed up. I want something that is reliable, and can fairly easily be fixed by some independent mechanic in some small town if something does go wrong. Generic tires, for instance. Reliability in my country unfortunately also extends to the electric grid, which has become more and more unreliable over the last 25 years. And I do not want something that constantly sends not only telemetry, but also more onerous data like the feed from an internal camera back home. I also do not want my car to be disabled remotely just because I wake up one day to find myself in an out-of-fashion group or in a country whose regime (which I don't like on the best of days) chose the wrong side in some conflict.

You're not going to tempt me out of that need for independence with more speed or longer range or greater show-off creds. (Yeah, I don't buy Apple products either.)

So I'll probably hang on to the current car as long as possible, again. Let's see where we're at in 15 or 20 years...

Possibly. My thinking however is that there may be a non-negligible amount of experienced coders who would notice such shenanigans and get the word out, which would junk Claude's reputation quite quick. Implicit (unverified) trust is one of the most important foundations of social engineering exploits, but at the same time a very difficult commodity to acquire.

I guess my situation applies to very few people, but I am paid by the hour (and have a certain quota of hours to fill), so I would not lift an ibrow, where Eye in this situation. (Sorry. Have to take humor where I can find it, even if it's half-assed like this....) They are quick to send out mails: office not available today, please work from home.

However, the 2 hours or so per day spent commuting to an office are not part of that hourly quota. (We mostly WFH but have a certain quota of office days to fill, for no compelling reason.) So working those hours for free, as a chauffeur for myself, just to be an actor that makes the expensive office building look occupied, sits less well with me.
