I've always liked the paper maps we got from AAA (and I never understood why people had trouble refolding them). Sure, Maps will take me directly from Point A to Point B, but it misses the far more interesting detours that you can jump out at you on a paper map. Where we live I can go from our town to the next one in X-many minutes along flat featureless Highway 2, or I can get there in X+3 minutes on Ben Howard Road as it winds along the Skykomish River, over hills and through farmland.

We gave up on Apple maps the third time it sent us on a pointless detour through a residential neighborhood and then back to the spot where Google Maps on my Samsung phone diverged from their route. Even on my wife's iToy we use Google Maps now. To be truthful to date I have not seen anything on her phone that I liked better than what was on my phone, except the camera has better low-light resolution.

Originally we got it for free when I worked at Amazon, since I was alpha and beta testing a lot of stuff for them (and I got probably $300 in Alexa hardware and over $1000 in Ring stuff for free!) We've found it very convenient, and it works really well with Alexa. When I left Amazon we kept paying for the 'Ultimate Music' subscription, just considering it one of our luxuries like good food. Very wide selection of music, easy to make playlists (although I wish their 'shuffle' feature in the playlists were really more random), and the built-in playlists are pretty good. We have it playing pretty much all day when the TV isn't on. I can even just say, "Alexa play music we like" and it will play songs that we've told it we like. Once we trained Alexa to recognize our voices my wife can say, "Play music I like" and it will mostly play stuff that she's liked and not much that I did. We hardly ever play CDs any more because we can tell it, "Play the album 'Dark Side Of The Moon'" or, "Play music by Juan Luis Guerra" or even, "Play '70s folk music" and it will.

I've seen articles here complaining about ads on the Echo Show, but we've never seen any. Maybe because we have the 'Ultimate' subscription, or maybe it's just something in our settings from when I worked at Amazon.

This thing may go online in 10 years.

Nope, expected completion is 2030, you're stuck in the past. China just completed the Fuqing 5 nuclear plant in six years from breaking ground, and Terra Power started construction on the Natrium plant last year so that doesn't sound unreasonable.

We're way behind the curve here. China has approved construction of 10 new reactors per year for the last three years, and is currently in the process of exporting 15 more. Their products and processes are years ahead of ours in the west, and because of our moronic politics we're not even ALLOWED to purchase their technology. That's some "free market" we have.

This guy lives and works in China and writes mostly about business issues (with occasional digressions).

This is not a new project. Terra Power has been trying to get approvals since the turn of the century, running into constant interference from the political establishment of both sides, who hate him (a billionaire using his money to help poor people? That simply CANNOT be allowed!!) It sounds like in the current political chaos someone wasn't paying attention so they finally allowed the approval.

every time it's been tried there's been show-stopper corrosion which they thought they had solved in their design already.

Understood but I think you should keep in mind that Molten-salt batteries have become a thing.

That doesn't guarantee that it will happen again, but...

If you never try then you can never succeed. Science is full of repeated failures... and then someone gets it right.

Comment Sodium-cooled fast reactor* (Score 5, Informative) 72

Natrium is an older term for sodium, a chemical element with the symbol Na

So really, this is a sodium-cooled fast reactor which means they are using molten salt for thermal energy storage. If I understand correctly, development has been held back material science problems since sodium is chemically reactive.

Why sodium? The benefit of sodium is that you reduce the risk of a meltdown since water has a relatively low boiling point. This allows the reactor to be "hot" run which is called a "fast reactor" Water-based fast reactors have to be run under high pressure so there is more risk involved.

Why makes fast reactors desirable? Per Wikipedia:

All fast reactors have several advantages over the current fleet of water based reactors in that the waste streams are significantly reduced. Crucially, when a reactor runs on fast neutrons, the plutonium isotopes are far more likely to fission upon absorbing a neutron. Thus, fast neutrons have a smaller chance of being captured by the uranium and plutonium, but when they are captured, have a much bigger chance of causing a fission. This means that the inventory of transuranic waste is non existent from fast reactors.
