Look up interesting plans Brazilians had at around the time and try to make them happen. I'm sure someone had a crazy plan. While doing research for Austria in 1900, I found this crazy plan some dude had to build a canal from Trieste to Vienna. Turns out the plan wasn't really do-able, but I'm sure there's plenty of crazy shit people have planned throughout history that may have been possible but never received enough support or funding to be done. So try to find stuff for Brazil and make it happen. Brazil has a lot of underdeveloped land, and therefore a lot of potential.
