I don't think the actual cap really matters if the per-GB and base pricing reflects the true costs. If it's low it means heavy users pay more, if it's high, light users pay more.
Which is algebraically identical to a monthly charge and data cap with overage charge. The main issue is the overage charge is too high, it should be like 1 cent per GB (Comcast is charging 20x that).
I come from a place that has in the last 13 years more than 500K people died, in almost 28% of the cases it happened roads/highways due to illegal overtaking and over-speeding.
I would like to have in my lifetime a car that had some sort of technology that could prevent some of those accidents, and autonomous cars could help on it.
Aren’t the LHC magnets niobium-titanium? Those aren’t high temperature superconductors. Though it is indeed a metal under any definition. The rule of thumb is that high-temperature superconductors can be cooled by liquid nitrogen alone. This is not the case of the LHC magnets, which also have a liquid helium cooling loop.
> They're metallic, so you can form them into the shape you need without having to manufacture it in that shape to begin with, since you'd need another superconductor to join pieces like glue, which we don't have.
The term “metallic” is unhelpful because often in material science it just means an electronic conductor (a material with a non-zero density of states at the Fermi level). Under that definition, some ceramics are metallic, and the opposite of “metallic” is “insulator”, or sometimes “semi-conductor”.
YBCO, which is probably the most used high-temperature superconductor, is an oxyde, so a ceramic, but still an electronic (super)conductor, so metallic. The fact that it’s an oxyde does not prevent its use, notably in spherical tokamaks.
So I don’t know the person you’re referencing but their background work on the subject seems less than adequate, from what you say.
"In almost all applications of superconductors, they don't use high-temperature ones. [...] The ones [the superconductors] that see use in the LHC, for instance, aren't [high temperature superconductors]."
It just has a sentence in the middle of it that confuses you into thinking their antecedents are "the HTSCs" and "ceramic" instead of "the SCs" and "HTSCs".
