This is the kind of new-style personal transportion I can get behind. As even my six year old son will tell you, Hydrogen is the most common element in the universe-- "numero uno" on the periodic table.

Besides that, flying makes more sense than traveling on the ground: it takes more energy of course, but you know what they say about the fastest route from "point A" to "point B", which is nigh-on impossible without going airborne. And in a place like Minnesota, forget continually plowing and salting all of the surfaces-- just cruise over them.

Another possibility would be resurrecting "ground effect" vehicles: they use less energy than actual aircraft, but still ride aloft.
