Except that was a completely different incident and it occurred in the United States, not the UK. The Daily Mail did try to make hay out of the idpol angle, but the British can't reasonably be accused of shirking responsibility for the

That isn't really "renewing", though. If part of the process involves the substance being dispersed in the environment and then extracted again, that's different from capturing waste as it's produced. Furthermore, y

Uranium is more concentrated in the ocean than other transition metals because it forms a stable anion (UO4(2-), IIRC). The most abundant transition metal in the ocean is actually molybdenum, followed by vanadium; most TMs have negligible s

Lithium-ion batteries are the benchmark for all of these, except maybe the explosion thing. They offer thousands of cycles where many prototypes only last a few hundred. They basically function in the range -10–+40 C while some prototypes

EOS is just a conventional zinc-nickel battery, or so I thought. Their Coulombic efficiency is bad (<80%) and grid storage demand isn't high enough to justify using a much less efficient battery to achieve a much larger scale system

The answer is, as for all X-air batteries: [x] it is incapable of delivering current at sufficient levels. "High power density" in the paper means 220 milliwatts per square centimeter. That's higher than other air-breathing

Aerosols were probably sulfuric acid. Unfortunately this has negative side-effects. Aerosol can also be produced by monoterpenes, e.g. pinene, but there is disagreement about whether this can be helpful.

It's supposed to be quadratic, IIRC. Total GHG is linear, then integrate over time. Of course this is a crude approach, but it's suggestive.

I was pretty disappointed to learn that hexane is still commonly used for solvent extraction of vegetable oil. Residual levels are generally < 50 ppb, but hexane metabolites can covalently bond to biomolecules [1] and take years to be re

This comment does not merit wide attention. You've cherry-picked a quote from the abstract in a highly misleading way. The adjusted p-value is <0.01, which is a perfectly reasonable confidence interval. Odds ratio is 4.6 ffs. >
