"That is a lightflyer." He points. "It's a flying vehicle that goes very fast. A float pallet is a levitating platform that can be hauled around as though it's mostly weightless regardless of how much stuff you pile onto it, as long as you don't exceed the safety limitations and break the thing. And a lift tube is a different application of the same technology used in float pallets, which allows wingless people to move from one floor to another inside a building without having to go up and down stairs. If none of those sounds sufficiently exciting to be worth a look, I'm sure I can think of more."
