Now if you had a really, really large aircraft operating in ground effect at relatively low speed, you might be able to make it work.
I did a back of envelope calculation a few years back, and an electric ground effect plane about three times the weight of an A380 on the SF to LA run actually was feasible. It would have to operate over water, though, because it has to fly about 50 feet above the surface to remain in ground effect the whole way.
It would be expensive, but compared to high speed rail, relatively cheap. If you just gotta get from SF to LA in two hours all electric, it is the only way.
