This is the kind of stuff that I love to find! Technologies that are currently found only in science fiction, such as interstellar travel, all rely on a number of unspoken assumptions… for instance, that the people traveling that way have some way of eating during the trip. (Even if they make the trip in some kind of stasis, the machines that maintain and monitor them will have to be fueled somehow.) Hydroponic gardens are all well and good, but they still rely on heat and light energy — energy that can’t come from good ol’ Sol when you’re out beyond Pluto’s orbit. This kind of discovery is crucial to making such technologies possible.
