I note that only one of the photos accompanying the article features PLASTIC rubbish. curious
The article mentions hydrogen from electrolysis of water, but I think a bigger source in the future could be steam reforming of biomass. That is, when you heat biomass (plant matter, sewage sludge, maybe even municipal garbage) to about 300C in steam, the organic matter breaks down into simple molecules like hydrogen, carbon monoxide (highly flammable!), methanol, elemental carbon (biochar) and miscellaneous others. Some of those molecules can be recovered for important chemical feedstock (since we won’t have petroleum or natural gas as feedstocks anymore, right?), and the gas can be fuel.
In the early days of natural gas use, towns would “reform” the methane (CH4) by reacting it with steam to make carbon monoxide (CO) and 3 molecules of H2 - a mixture known as “city gas”. It is not new technology.
gotta admit, that is a lot safer approach than trying some shit on the real thing
The statistic of low Firefox use is based on accessing US government websites. Could it be that there is significantly LESS government site access by the population of users that prefer Firefox? As a corollary I recently read that game companies observed significantly HIGHER bug reporting from Linux users on Steam, not because there were more Linux-related bugs, but simply because that set of users were more likely to initiate bug reports. Of course Firefox is not Linux and Steam is not the world, but a statistic from a relatively narrow segment of the internet should not be assumed representative of the whole.
In the US, stove burners are rated in the confusing units of “BTUs” which is actually a unit of energy, not power. When they say BTU, they mean BTU/hour. The highest-rated burners on a typical stove are about 10,000 Btu (per hour), but high-end stoves can get up to about 18000 - that is equivalent to about 5000 watts. My single-element induction top is only rated for about 1000 watts. So although it heats and cools rapidly, I suspect it is not up to the demands of wok cooking (unless one wants to cook only very small portions).
not Chinese, but I cook a lot with a wok. I also have a single induction cooktop and surprisingly, the wok has enough iron to work with it while some old cheap conventional cookware did not. However, wok cooking needs to be hot all over the wok and not just in that little point where the wok is close enough to the induction coil.
I have a conventional propane stove which I need to keep, because here in Puerto Rico the power system is quite unreliable (especially during a bad hurricane year). But the conventional stove burners are not really hot enough. With a 1/16 - inch drill bit I could increase one of the burners capacity substantially. I painted the stove knob red so people have some warning when they light that burner! It burns more gas, but wok cooking is really fast, so in the long run it is probably more efficient than lots of other cooking approaches.
I would definitely consider a wok-shaped induction heater. Induction heating is quite remarkable.
Have you tried your hand at biochar? I know composting the chips for mulch is high value in a farm operation, but a few tons of biochar can work like a permanent upgrade - improving the soil permanently with one addition - though ongoing permaculture operation continues. I am about to make a biochar cooker out of two steel barrels - inner fuel chamber and outer draft shell. It would probably be more effective with wood scraps than chips though - some air passages through the fuel.
To test it out for myself, I made a miniature version documented at https://github.com/jcadej/TLUD-biochar-reactor (uses a gallon paint can for the fuel chamber. You could test it small and see how it does with wood chips. When I make my bigger version, I will add it to the github project. My rough idea is to cut one barrel down the side and squeeze it smaller and bolt it so it fits inside the other.
I’d hate to think modern society is based on a giant elaboration of poker, but I can’t rule it out - it MIGHT not be the worst outcome, but a pseudo-equilibrium far from the best. Every young person knows something accessible in the past is now lost to them - not sure what it is, but there is a hole. And yet, the social track laid out is almost unavoidable.
I traveled a good bit the past 20 years and I’ve experienced first-hand the really hard work and the immense gratification of simple farming. Nobody wants to live like that (at least so they think). Having done it, I can’t even say I recommend it over what modern society seems to offer. But since the best option on offer is not a true equilibrium, as the climate is making abundantly clear, what is on offer may be illusory. An alternative equilibrium - tried and true - is worth considering when opportunity arises: subsistence farming. It is NOT simple or easy - don’t wait until there is no other option.
I have heard this, and I can imagine it is true, but have you seen any analysis? There must be a large crew traveling and lots of equipment - transportation is a big user of petroleum in general – for entertainment. Though they say the entertainment is good.
Swimming pools are normally constructed empty. They were withstanding surrounding soil before they were filled, and concrete strength increases with age (for about 90 days, typically). On the other hand, a sunken structure like a pool that is roofed over, becomes a “confined space”. Unlike a typical structure, heavier-than-air gases cannot escape from the pool. Such gases could originate from the drain system or flow from leakage outside the pool area. For examples, leaking propane or various gases from sewer lines in the vicinity. A sunken greenhouse would almost certainly be a building code violation for that reason. If you build it, ventilate it by means both active and passive and do not enter if you can’t verify that ventilation is working.
the ultimate run-away train! No matter how impossibly big it is, it just grew infinitely bigger in the past second.
I have plain ol’ Ubuntu LTS and I do not recall a Steam crash in a decade. Playing with Nvidia GPU on AMD Ryzen in recent years.
What the author is saying, I think, is that the inevitability of the tragedy is the right-wing concept. The concept of the commons is totally legit and the tragedy that can befall it from unregulated use is also clear. The right-wing concept that is dubious is that humans will self-regulate and do not benefit from governance.
https://www.youtube.com/channel/UCxG5KAao5rJY3vvwbVUSv4g - The “This Is CDR” series is particularly good. OpenAir Collective is all-volunteer and focused on carbon dioxide removal (which is secondary to eliminating fossil fuel use, but it is something I can actually work on and make progress). In the long run, CDR is no less vital than decarbonizing.
top slab is about 230 or 240 pounds. Wood base is only about 15 or so; light. I made no attachment between the concrete and the wood - just gravity.
These are some good points. The more traditional engineering disciplines have a depth of methods and practices that developed over time, and software engineering is - what? only maybe 50 years old or so? I have not worked with software engineers, but with all other sorts, so I know if there is engineering going on in software development there will be certain methods in place: preliminary designs that senior teams evaluate and compare, interdisciplinary review so the features of design that “work” for one objective also do not detract from others, and quality control - nobody works alone - every calculation and every sentence and every communication is documented, reviewed by someone else, and recorded permanently.
I can imagine that some software engineering efforts must bring some of these tools to bear, sometimes - but the refrain in software development has long been “we don’t have time or funds to do it that way - things are moving too fast, or it is too competitive.” Which maybe all that is true, and maybe it can all be fun and games since nobody can get hurt. So if game developers want to call themselves engineers regardless of whether they follow, or even know about standards of their industry (let alone any others’), no harm, no foul, right?
An old friend of mine wrote the autopilot software for commercial passenger jets - though he retired about 25 years ago. He was undoubtedly engaged in a project that nowadays would be dubbed software engineering. The aerospace company included him in the team with a whole slew of different engineers of all sorts and they did all the sort of engineerish things. But I don’t have the impression that much software goes through that kind of scrutiny - even software that demonstrably deeply affects lives and society. In a way this is like criticizing the engineering of an AR-15; what were the engineers thinking to develop something that would kill people?! But it seems like with software, the development has effects that are a complete shock even to the developers: facebook algorithms weren’t devised to promote teen suicide, it was just an unforeseen side effect for a while.
I think it is time for software engineering to be taken seriously. And there is professional licensing. The problem is that corporations are dubbing their staff as software engineers a lot of times, when there is no licensed engineer in the building and there are no engineering systems in place. It is fine for me to say that I engineered the rickety shelves in my garage, because I’m an engineer and therefore it must be so, but that is some sensationally bad logic. They could collapse at any moment - I’m a chemical engineer.
Thank you for this correction. I will make a note that professional engineering has nothing to do with engineering - I don’t know how I have been so confused for so long!
Tthis is perhaps good news, but it does not amount to a change of course, unfortunately. If we have passed peak emissions, it is still a long way from net-zero emissions. Like if you pass your peak rate of overspending your salary, but you are still continuing to go farther into debt. Even when you get to parity between salary and expenditures, you will STILL have the accumulated debt and in the case of CO2, that debt is wreaking ecosystem destruction. Do not cheer this news.
