> Too slow for transportation, maybe. But leisure travel? Imagine a one week air safari over the Serengeti, Ngoro Ngoro crater, and Kruger Park. It could be awesome.
Well, if we're talking about weird Sci-Fi ideas (that might be possible), lets just go all in on it.
Rocket launches are extremely expensive, and most of it is in the lifting costs. Would it be cheaper to "lift" a rocket with hydrogen slowly?
Yeah, we also need to get enough kinetic energy to enter orbit. But surely getting rid of a huge chunk of "Gravity" costs could lead to substantial rocket-fuel savings?
