High speed rail in California would also be great, but they've been working on it for 15 years already, and at this rate, it doesn't look like the project will finish in the next 50 years.
Still, I am excited to see ground-effect vehicles/ekranoplans back in vogue!
How are you managing battery degradation, especially given that you're planning for high charge rates with quick turnaround? Do you have an idea of how many pack replacements you'll need over the lifetime of the rest of the aircraft?
Amprius is planning to offer a silicon nanowire anode sometime in the next decade it seems, which probably won't double the capacity, but it would be a significant improvement.
It can't, at least not nonstop: 160 nautical mile range, and SF to LA is about twice that straight line, and even longer following an overwater route.
The planned 400nm range nexg gen battery tech upgrade is probably in the neighborhood, though.
Or do that thing Tesla tried to do: Land the plane, swap out the battery for a fully charged one, take off again.
EDIT: Here's why swapping batteries isn't likely worthwhile: https://news.ycombinator.com/item?id=36053417
But I bet navigating safely across the Bay and under the Golden Gate Bridge (probably in "hull" mode) could end up being a comparable amount of time in its own right. Having all that other marine traffic around in all directions (and maybe stricter noise restriction) is a big limitation.
