Something to do with transportation and logistics really. Free trade is just not going away despite populists doing their dardnest to make it more difficult and free trade runs on transporting stuff from A to B easily. If you could innovate something minor in that field, I'm talking something that impacts maybe 5% of the shipping process, that's an absurdly big market. However, don't do like the airlines and build your business plan on having exclusive agreements with nice and naive governments. Once that special treatment stops and they let smaller players in party's over.
