That's one hell of an escape to reality.

As usual, this was a fun and fascinating episode. Thank you to Steve and the Rogues.

Gotta say it was a little odd to not mention the executive orders about immigration, which caused chaos in labs across the country, and a lot of fear and uncertainty for international students, post docs, and professors.

We have been driving a diesel ute and hatchback for decades, just like the majority of passenger cars in Europe.

Did "what's the word?" get skipped this week?

I thought that everyone automatically associated diesel with the man, Diesel, who invented it.

Why would they imagine that solid metallic hydrogen might be stable or meta-stable? Diamonds are a bad analogy because diamond is a crystal. Yes, it forms under great pressure, but it's a crystal lattice with extremely strong covalent bonds linking all the carbon atoms in a three-dimensional grid.

Hydrogen becomes a metal at low enough temperature and high enough pressure, but metals form amorphous solids, and all metals melt above a temperature that is characteristic of each metal. So why would they think metallic hydrogen would not melt like all other metals, and then evaporate when the temperature goes above the boiling point?

ETA: And as for rocket fuel, given the lengths needed to go to to make metallic hydrogen it would be damned expensive rocket fuel.

If you want to weigh less, rather than looking for a spot on the equator with less mass underfoot, you need to go to the top of an equatorial mountain. Mt. Chimborazo in Ecuador should do nicely. Of course, you'd freeze to death when you took your clothing off to step on the scale. The summit of Chimborazo is the point on the surface of the Earth that is farthest from the Earth's center, due to the slight equatorial bulge.

They should have interviewed the authors of the paper on metallic hydrogen like BBC "Science in Action" did last week.

Indeed, the rogues seemed to be unaware that most small cars in Europe are Diesel powered.

Diesel-powered cars are a mixed blessing. On the plus side they have ~20% better MPG so have lower CO2 emissions per mile. But on the negative side the NOx and PM25 small particle emissions are very bad, creating a local heath hazard. And Diesels quite literally stink and are much noisier. Just visit any European city and you'll be amazed at the amount of diesel smell and noise they are willing to put up with.

Overall Diesel cars are more of a curse than a blessing: a tax gimmick that got way out of hand.

The cause of the Volkswagen Diesel scandal was a desire for the appearance of a 'clean diesel' without the associated cost. In Europe VW got away with that cheating because the governments are major shareholders. In the USA, the EPA had more of a bite (pre-Trump, that is).

Mopeds in many European cities are a menace too. Loud and stinky as all get out.

When I hear Diesel, I think of Nurse Diesel of the Institute for the Very Very Nervous
