Finally something the EU can invest in with those 600 billion. Or buy it, like lots of EU startups were by FAANG companies years ago. Tramp says it's dead tech, so it's ok.

The part that controls/balances the discharge profiles, right? Because sodium batteries have a more non-linear discharge pattern.
Mine is 10 years old by now...never had ads...if it connected to the internet it would probably get bricked.
Wait, so it isn't getting worse, I'm just more aware of how flawed it is through long-term exposure?
Yeah, the brine is where various useful ions can be further extracted from. https://news.mit.edu/2019/brine-desalianation-waste-sodium-hydroxide-0213
Needless to say, at 19,000 Kelvin, the solid gold sample blew past that boundary, heating up to more than 14 times its melting point, which is about 1,300 Kelvin. The team suggests the speed of the heating likely kept the gold from expanding. They blasted the gold to its record-setting temperature in just 45 femtoseconds, or 45 millionths of a billionth of a second.
“The thing that’s intriguing here is to ask the question of whether or not it’s possible to beat virtually all of thermodynamics, just by being quick enough so that thermodynamics doesn’t really apply in the sense that you might think about it
The team notes that the second law of thermodynamics, which states that disorder increases with time, still stands—their work did not disprove it. That’s because the gold atoms reached their extreme temperature before they had time to become disordered, White tells Nature’s Dan Garisto.
Even still, researchers are now faced with a question they had considered all but completely solved nearly four decades ago, per New Scientist: How hot can something really get before it melts? If a material is heated quickly enough, there might be no limit, per the SLAC statement.
Sort of reminds me of the energy-time version uncertainty principle: if an interval is short enough, energy fluctuations can be extremely high.
What I'd like to know here is what the duration threshold to would allow fusion to start is.
honest mistake, oregano olive oil looks similar

Fine, I can say this in a way that does not violate energy conservation but still uses the energy-time uncertainty principle:
Say you have a system with two levels, hot and cold like the gold sheet in this experiment. Then I can take a linear combination of these two (stationary) states, between which which the period of oscillation would be deltat=h/deltaE, which would be the time for the system to "heat" and "cool" within 45 femtoseconds. (lifted from Griffiths, page 143)
That would give a deltaE>1.5E-20J compared with kT (T=19000K) = 27E-20J 🤔 (T=1300K) = 1.8E-20J so the fusion T is close to the oscillation limit, the extra energy for 19000K is not going to do anything unless the cooling slows down.
Soo...I don't understand the point of the experiment. It just looks like they're exciting ~~atoms~~ metal and then letting them quickly deexcite radiatively...and then wonder why they won't absorb huge amounts of energy and melt (if the energy remained within the system, it would). I probably would have to get the actual paper, but I don't wanna 😛
