and often 800 miles in a day (takes about 13-14 hours driving)
Oh wow. After my last trip that was supposed to take like 9 hours and ended up more like 12, I decided to never do that to myself ever again. But I guess if you have multiple drivers that can share the burden, such along day on the road is still an option.
I absolutely loved that game.
I'd rather force safety requirements on all cars. Like limiting blind spots at the front and everywhere else, limiting speeds of vehicles above certain weights, increasing license requirements for vehicles that have higher safety impact etc.
Hydrogen has its place, and we need plenty of it in places where we don't have viable alternatives. Road transport is pretty far down that list though.
And don't forget that the plants are really expensive. Having them produce very little or even no power for half the time doesn't help that at all.
Thermal storage needs to be quite large though, at least with the stone/brick like mass they used back then. And you need to isolate it, otherwise you have no control over the release of that stored heat. I wonder if new materials, maybe something that undergoes phase change in that temperature range, could be a lot more space efficient.
Interesting. I don't have a car any more and no kids, but my friends that do always tell me their kids need more breaks than the electric car. And I always found that I need breaks every 2-3 hours anyway to keep the alertness high. I can't imagine going 400 miles in one go.
