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.
