You can already buy single use phone chargers at convenience stores which, while ecologically horrifying, also speaks to how the economics of mass manufacturing work. Then again, are single use phone chargers any more ecologically horrifying than non-rechargeable AA batteries or have they simply been around for much longer and have become mundane.

I recently saw those, I was shocked by both the price and the fact they were single use, surely a charging port and the extra circuitry would barely touch the BoM? I've got a battery bank integrated into my wallet anyway, so I won't be caught out.

Actually, I took apart a similar device, a single-use e-cigarette battery, and it turns out to be identical to the rechargeable version, except on the tiny PCB inside the chip for handling the charging from USB was absent. The battery was the same Li-ion rechargeable, supplied charged up for ~1 days usage. The economics of these cheap electronics are insane...

Reliability, generally. Consistency, afterward. Cost, third. OLED was hung up for years because the blue pixels had 1/100 to 1/10 the lifetime of the red and green one. In addition, you would be stunned at just how good our visual system is at picking out imperfections. Anything less than perfect (especially involving green) will produce complaints. After both of those, you can talk about cost and efficiency.

That's informative, thanks. And I think you're point is on point: people would buy these and not be happy with them, because they want a real monitor. There's also a group of people who want them just to be able to ready articles and write articles (and code, etc) outside, and without charging a battery as often, and would be happy with lo-fi graphics.

Hah, not exactly what most people think when you use the word 'print' but then again ... People have asked what is the impact of 'free' CPUs. Something Dave Rosenthal realized way back in the 90's was that the electronics for driving a display could be printed on the margins of the display and eliminate the need for a separate controller board. Having watched the evolution of displays and seeing Mary Lou Jepsen's wor…

I used to use make Apple ][ screen snapshots with glow in the dark silly putty, but they only lasted a minute or so. But while it lasted, you could perform all kinds of cool distortion effects, kind of like Kai Power Goo.

I have a feeling that personal displays (as with cellphones now) will continue to exist until man stops existing. I imagine the opposite trend will occur, where each person owns fewer and fewer display devices. I can't imagine a justification now, or in the future, for buying some single use display. Once we get to a nice head mounted AR system, it would be very silly to have anything more.

People like having something special and permanent. All those pictures on your general-purpose computing device? They're gone as soon as you lose the device, get ransomware, and/or temporarily run out of money to renew the cloud storage subscription. A polaroid picture that starts playing as soon as you attach it to a suitable power source (please make it something standard like an AA battery or USB cable), on the ot…

> All those pictures on your general-purpose computing device?

The trend is, and I believe will continue to be, not using your own memory for long term storage. It's a nearly impossible task. If you're storing anything important on a single device, be it a single use display, or a cellphone, or a memory card/disk, you will lose that data, 100% guaranteed.

We're already moving towards transparent backup of all user data. This trend will continue, because people will become more and more aware that they can't save their own data.

Fun, albeit sad fact: In Norway, 99% (quite literally, not exaggerating) of bookstores are owned by the various publishing houses. They've pushed an eBook standard where you buy a dedicated reader, then buy proprietary memory cards in sleeves much like the ones used for compact cassettes - the idea being that people want something tangible, even when buying eBooks. (The cynical among us assume they just invented that…

Now to a tangent on a tangent. The advantages of the Scandinavian social-welfare systems are well-known. What are some (unrelated to the problem of funding welfare) economic problems faced by Norway? You just cited an interesting one. I remember a story about milk import restrictions, but I could be very mistaken. But anyway, between the effects of oil exports on exchange rates (alternatively, the problems of exchang…

(Keep in mind while reading this that I am bordering on the libertarian - it may shine through here and there.)

Norwegian farming (including dairy/milk products) is tightly regulated and subsidized, basically a necessity if one is to farm here at all - after all, (slight exaggeration) mountains everywhere and winter half the year does not lend itself well to farming.

Result being that most all vegetables, meats and dairy products are purchased from farmers by cooperatives; the prices are set by the authorities as part of negotiations with the farmers' association annually. These cooperatives then sell the produce on to retailers and industry, ensuring a steady income to farmers.

This model wouldn't work if the same products could be freely imported from countries more suited (less mountains, less winter!) to farming - so we impose heavy tariffs on most products from abroad - with exemptions for produce from some of the least developed countries.

For instance, lamb is taxed at 429% on the goods value to make import prices comparable to the cost of producing it in Norway. Same goes for a number of dairy products - we have import quotas on, say, cheese - and if imports are too large in a given year, heavy tariffs are imposed to limit it.

The upside to this policy is that it is possible to make a living from farming even in the subarctic regions; it can be argued (IMHO, rightly so, even if it clashes with my libertarian credentials!) that farming is beneficial to local communities - unless the pastures are tended to, the part of the country which is not barren mountain would be covered in shrubs in no time at all.

The downside, obviously, being that food is much more expensive than it needs be; this issue is countered to a large extent by our petroleum-boosted economy, ensuring that even at the artificially inflated prices, food is comparatively cheap in Norway. Also, as the tariffs are not imposed only on basic foodstuffs, it ensures that specialities which already fetch a premium in global markets - think pata negra etc. - are outrageously expensive here.

In broader terms, one of our major challenges in the decades to come is that we've tended to solve - nah, make that postpone - any problem by throwing petrodollars at it; as oil production decreases, we've got some pretty tough choices ahead as income slows while expenses skyrocket.

For instance, we've relied on a pay-as-you-go pensions system; as people tend to live longer (and we've, to an extent (exaggeration again) kept unemployment numbers artificially low by providing disability benefits to the long-term unemployed), this is not sustainable (same situation as in a number of developed countries).

Now, pensions is to an extent cushioned by our close-to-a-trillion USD petroleum fund, but then there's all sorts of other obligations - say, tax-funded healthcare, (very) generous sick leave terms &c.

So - we'll need to axe our expenses, but in our very consensus-driven political system, no politician would dare step forward and actually DO something - after all, that would see his or hers chances of reelection plummet. You don't win elections by promising people that they will get less paid in retirement or when ill.

Oops. I just noticed that you said 'unrelated to the problem of funding welfare.' My bad.

A number of sectors face issues similar to that of the publishing industry - it is a small market, and with Norwegian hardly being a world language (All told, some 5 million native speakers), anything involving the Norwegian language sooner or later becomes an effort to prop it up - so publishing is not seen just as publishing; it is an effort to keep Norwegian alive and well. This has led to legislation which - believe it or not - makes it illegal to sell newly published books at a discount; this is to ensure that publishers get a decent return on translating and publishing books in Norwegian, but leads to such absurd situations like me wishing to buy the latest Jo Nesbo thriller as an eBook would cost me more than buying it on dead trees (as a 25% sales tax is imposed on eBooks, while paper books are exempt), but buying the same book on my Kindle or on paper via Amazon, translated into English, can be done at (typically) less than 20% of the over-the-counter Norwegian price.

Again, I can see where the advocates of such policies are coming from, but it does mean that we have a number of sectors of our economy which needs to be protected from the world at large through quotas and taxes. Now, obviously, everyone thinks their own sector is special and needs this kind of protection, whereas all others are just freeloading whiners who make everything more expensive than it needs to be for the rest of us.

Rant over. (I'll try to compose something a bit more articulate if some of the above piqued your interest. :)

Your grandchildren are unlikely to be using AA batteries or USB cables.

how about a solar panel on the back (or a transparant one on the front). How about heat activated. How about activated by radiation in the air (microwaves).

Absolutely

But both are trivial to create adapters for as long as you have a suitable source of electricity.

Unless everything (finally) goes wireless.

Even then there will need to be receivers that tap the wireless power source. To make that hard to regulate to a suitable current is exceedingly unlikely. Unless the device is extremely sensitive, if you can get any kind of electromagnetic power, converting it to electricity at a reasonable voltage might not necessarily be quick and easy if no current tech is available, but it's the kind of thing you can achieve from near first principles in the garage with some basic tools and a spool of copper wire.

But that's only necessary if you can't get hold of a source of electricity (such as a wireless receiver) and a voltage regulator of some sort (likely to exist as part of said wireless receivers).

In the past we've had problems recovering data from magnetic disks and the like, but powering ancient devices with simple power input requirements have not generally been very hard, and it's not likely to become so anytime soon unless not just every computer but every lightbulb, kettle, electrical oven and every other little appliance suddenly start receiving energy in a fundamentally different way.

Only about 5% of gold is used in industry. The rest is stored as bullion or used in jewellery.

You sound very confident with using strong words like "absolutely irrelevant" and "completely fallacious" and "actual mindless busywork" and definitive quantities like "less than 0.01%", when it turns out that your numbers are off by almost an order of magnitude base 10 or three orders of magnitude base 2. So they're only burning eight times more coal than you claim (and rising). You're saying that because worldwide…

I could do without the smug lecture, guy. Anyway:

From https://digiconomist.net/bitcoin-energy-consumption

>16.26 TWh/yr

From https://en.wikipedia.org/wiki/World_energy_consumption

>109613 TWh/yr

Which yields 0.0148%. So you're right, not less than 0.01%, less than 0.015% instead. Still a far cry from 0.08$.

---

I would really like to know when have I said my smartphone was gold-free, how that is in any way relevant to the discussion anyway and not a completely inane pseudo-gotcha, I would like to know why you keep linking bitcoin mining to coal (another completely transparent appeal to emotion), I would like to know when have I said worldwide production of gold is insignificant... I would like to know all those things but from the tone of your confident lecture responding to points I didn't even make I conclude you're not really into discussing this. Intellectual dishonesty is more your thing, I presume.

---

And my point is that gold (of which, again, 95% is "useless" in the sense of not being destined to any practical application) costs on the order of ~1MWh per ounce to mine. At a yearly production of ~3000 metric tons that comes to 109TWh, almost an order of magnitude more than bitcoin.

Thanks for the rant!

Norway is usually held up as the singular exception of the Resources Curse of oil because of its long-term commitment to a Sovereign Fund. Interesting to see that this is true, but kind of exists within the boundaries of the welfare-state-in-an-aging-society system.

I guess (mind, guess) is that the reason we did prove somewhat of an exception is that we had established an efficient (as such things go...) state in which the electorate trusted PRIOR to hitting the hydrocarbon jackpot.

Also, it probably helped that we were a society with (relatively speaking) small differences and no real tradition for a pronounced upper class.

This, however, is just unfounded musings on my behalf.
