There were a lot of factors that made NS Savannah economically unviable.
- it was built for individual cargo crates, just when crates were being replaced by ISO containers.
- it was small and had a streamlined hull, which meant very limited cargo capacity.
- it had a lot of space dedicated to passengers, just when passenger ships were being replaced by the jet airliner
- it was built at a time when diesel was very cheap
- the reactor personnel demanded similar wages to power station personnel, which worked out to a higher salary than the ship's officers. The labor dispute kept it out of service for a year.

Just a few years after the ship was decommissioned, increasing fuel prices meant conventional ships became as expensive to operate as Savannah.

It's peculiar that TFA labels the Boeing design the 'safe choice' when it hasn't flown yet, despite $0.5B of investment from NASA. And the Atlas V launch vehicle may have flown a lot of missions, but it isn't man-rated yet.
The SpaceX Dragon has flown several times, and has spent months in orbit docked to the ISS. Now I realize the manned Dragon has many new systems, but it seems to me SpaceX is a lot closer to a man-rated capsule than Boeing.

The French gave the British potentially valuable information on the Exocet's capabilities and limitations, and details on how it operated (e.g. its radar frequency, which you need to know if you want to use jamming).
Despite this, 4 of the 5 Exocets launched were hits, and damaged or sank British ships.

For sound, I've found the best venue is tractor pulling. All kinds of motive power in a single meet, from RR Griffons to high-strung V8 to helicopter turbines to methanol two-stage turbo engines. Because speeds are relatively low you can get really close to the track, it also means more immersion in the sound compared to having cars whizz by at 200+ km/h.

The casks are not concrete but steel. These are the general requirements. Notice the picture of a test train being crashed into a cask?

Sounds interesting. Did you publish this story?

The 150-ton casks weigh 150 tons because they're made strong enough to survive a derailment intact. This is unlike e.g. oil or ammonia tankers which have thin-walled tanks just strong enough to keep the liquid inside under normal circumstances.

Bullshit.

The Atlas V was designed at a time when the Soviet Union was crumbling. Using Russian engines was an American ploy to ensure world stability by keeping Russian rocket designers gainfully employed instead of leaving them fend for themselves, building God knows what for the highest bidder.

Did that work? Well, I haven't seen much progess in rocket technology by people crazy enough to start wars.

Has this tactic outlived its usefulness? Yes, in view of recent developments, it's time for a new arrangement. Oh, look, that's just what they're doing.

They use optical amplifiers. The signal stays in optical form, and is guided through a special section of fiber. A laser pumps energy into that fiber section, some of that energy ends up amplifying the signal. So it still needs power to drive the laser.

Neal Stephenson's utterly fantastic essay on the subject (all 42,000 words of it) for Wired

For each fiber, you need an amplifier every 50 (?) km. You may run into a weight limit where the amplifier pack becomes too heavy to be suspended by the cable during cable laying.
