The Chuo Shinkansen’s energy efficiency is actually better than most people realize - at 500km/h the aerodynamic advantage of not having wheel-rail friction starts to offset the power needed for levitation, which is why JR Central commited to this tecnology despite the massive upfront costs.

He’s full of shit about the Chuo Shinkansen. That’s gotta be one of the best places on the planet to build high speed maglev, from one of the world’s best rail companies with a well deserved superb reputation for punctuality, safety, and quality.
Not often I disagree with Adam Something about anything, but I think he’ll be proven wrong about the Chuo Shinkansen.

Isn’t the Chuo Shinkansen expected to have less capacity than the regular Shinkansen? I think the point that they’d be better off digging their tunnel and then running normal trains in it still stands.

728 passengers per train on L0 trains vs 1323 on N700 trains, yeah it’s lower capacity but it’s a brand new line that’s adding that much capacity, not subtracting from existing capacity. And they’re already building it, and have been giving passengers rides on the test track for years.
Why would they be better off abandoning proven technology with construction well underway, costs very securely under control, and clear and strong demand, just because some foreigners balk at the cost and timeline? Like, this is Japan, they don’t fuck around with this kind of stuff without damn good reason.
Also worth keeping in mind this speed puts the route in competition with air travel, in terms of cost and energy efficiency, so not only could it relieve some pressure from the Tokaido shinkansen but also regional airports.

He also is for removing anonymity in the Internet. Which so far is his worst take
