This is my experience travelling as well--Latin America has public transit that is an order of magnitude better than anything I've used in Canada or USA.
The success in s.a. highlights how much of a problem cars are causing in n.a. cities. Even if a well financed public or private bus service wanted to run frequent lines at rush hour, those buses would be stuck in slow car traffic. In nordic countries, the bus and trams have dedicated lanes, and mass transit is generally faster than cars.
The steam reactor I guess you might be describing is tokamak, which i agree will be a dead end technology.
There are interesting small fusion reactors that skip the steam step. They compress plasma magnetically, and when the fusion happens, the expanding plasma in turn expands the magnetic field, and the energy is harvested directly from the field. No steam and turbines.
I noticed the article didn't speculate on why, but I think you nailed it. This system is probably incompatible with a commercial site. It requires too many volunteers.
It almost looks like something I could make myself, but cutting those tiny pages while keeping them perfectly indexed would surely be where my diy would go wrong. Good work OP for working out that special sauce!
It's a clever idea, and it's encouraging to see that there are still clever ideas at the small-business scale still waiting to be invented.
"Teens having a laugh" can escalate quickly to, "... at someone else's expense," and this distinction is EXACTLY the sort of subtlety an algorithm can't filter.
This does not need to become a thread about bullying and self harm, but it should be recognized that this example is not benign or victimless.
This genie is out of the bottle, let us hope that laws about users are enough when the tools evolve faster than legislative response.
Amazon's "favoured nation" policy stipulates that vendors can't sell an item anywhere else for a lower price. This policy seems designed by them to put a moat between them and retail.
A well annotated cookbook like the article describes is truly an heirloom item, like a well seasoned griswold pan.
Moreso now, as good recipes in general are becoming harder to find via conventional internet searches. Most google results now are garbage clickbait sites with plagiarized recipes, just 'adjusted' enough to claim it's different than the original publication. The results of these adjustments vary from slightly worse to maybe the dog will eat it.
I now only trust new recipes from a few 'legacy' sites, (e.g. Serious Eats and classic culinary magazines,) but these resources are endangered. Classic print magazines are especially vulnerable to predation by vulture capital.
What a catch 22 for young people trying to learn to cook now... without prior experience it's hard to spot a broken recipe, but gaining experience requires using unbroken recipes. It break my heart how many novice cooks will be discouraged when they try broken clickbait garbage and think the failed result is their fault. Never mind the cost of food as a penalty of failure...
On the topic of the obesity epidemic, it's worth noting that lab rats with controlled diets are also getting fatter over time. The leading theories are microbiome shifts or environmental contamination (microplastics?,) but afaik no conclusive cause has been found.
When people fail at health, (as when they fail at finance or addiction), a lot of propaganda tells us to blame individuals, with no sympathy or awareness of our failing systems.
