They all have orange segments. Soccer game's almost over.. any.. second...

Corners like it's on rails.

Straight rails..

Why, how very few species of beetles there are!

From what I understand 'two, less a day' in provincial is WAY harder time than 'two, plus a day' in a federal medium security prison.

Nematodes laugh at beetles.

Thanks for the info!

So a hydrogen jet engine is... less than useless?

Diesel has an energy density of 45.5 megajoules per kilogram (MJ/kg), slightly lower than gasoline, which has an energy density of 45.8 MJ/kg. By contrast, hydrogen has an energy density of approximately 120 MJ/kg, almost three times more than diesel or gasoline. What this really means is that 1 kg of hydrogen, used in a fuel cell to power an electric motor, contains approximately the same energy as a gallon of diesel (rmi.org). site

As for storage weight: train, locomotive. Expensive: probably, until it's a mature industry.

I was wondering about gas storage cars on the trains, like old-timey coal tenders. Liquid hydrogen tanks?

Distances are different. Canada is thousands of miles across and very sparsely populated compared to Europe, for instance.

Overhead electric on 5,000+ km of freight rail? (That's as the crow flies.) Not at all practical.

I'm in Canada: it'd take new nuclear power or hydro dams (and there aren't accessible rivers) and two or three third-world strip mines to electrify rail here.

Paris to Berlin: 1054 km

Halifax to Vancouver: 6,150 km

Make hydrogen locomotives a thing. And shipping. And hydrogen made with green energy, not coal/oil.

Which comes first: Phone, or etc?

Much money, even more "Look, I'm rich."

We’ll never find out everything that’s going on in a tennis ball. It's called 'science' - we learn more and more about everything - forever.

The Woman King. It was wonderful.

The meme version is definitely better :-)

It was sub-standard obscenity?

Isn't that the sound of a broken machine that goes 'ping'?

Please: we're 'atomic space doctors.'

Sure it is! You can tell from the cloven hooves!

Pork-barreling at its wurst :-)
