It's a partly a problem of semantics, really. You can't really say it's a fusor runs at >45K because you're not in thermodynamic eq. (and therefore, there is no T). Likewise a laser runs at "negative" T, but

If the driver has snow tires, they're a safer driver than one with all-weather and a blank dash.

"TPMS sensor light is on (major safety risk)" It really isn't. (very) low tire pressure is a major safety risk. The TPMS sensors I've had all seem to go off at minor deviations (few psi) from the tire pressure; deviation

"introduce small quantities" small being the key qualifier.

Also, super conductors are limited by the amount of magnetic field, and therefore current they can carry [0] (above that limit they become normal conductors). Lowering T bellow Tc, increasing P increases the amount of current you can carry.

Ya, but the science popularizers always make it about transmission :S

Insignificant: EEs can lower the losses by increasing the line voltage [0], at the expense of other challenges (namely taller pylons). It's about 5% over the length of the line. Consider the other losses: - Thermal (gas turbine) cycle:

"well the pressure aspect wouldn't require constant energy input." But you have to put energy in to compress it, energy that is lost (since you're compressing it isothermally). Since we're talking about 1E6 atm, any

at a 1E6 atm, it's beyond useless for any practical application (unlike "normal" superconductors that can be used with a bit of N2 plumbing). If you scroll through the paper, you'll see they talk about using a diamond an
