Speaking of Jules Vern and Round The World.

A new sailing record was set recently, which didn't _quite_ beat 40 days - it took them 40 days and almost 11 hours.

If you've ever seen a SailGP boat flying up out of the water on their hydrofoils and doing 100kmh - imagine a 32m long 26m wide ocean going trimaran doing the same thing in a non stop circumnavigation of the globe. I think they _averaged_ 27knots or 50kmh!

If you _haven't_ seen the SailGP boats and are curious, here's somewhere to start: https://youtu.be/BQWOoP-Iwn8

And when the world was still flooded with money and the music was awesome (so 2004), Jeremy Clarkson did a series about inventions, one of them being the jet plane, and he flew commercial around the world in 120 hours: https://www.youtube.com/watch?v=o8D_UzMhjH8

This is an interesting article from a couple of days ago about tracking diy balloons long distance: https://spectrum.ieee.org/explore-stratosphere-diy-pico-ball.... Given the tracker can be built for $14 it might be worth it to test a version with just the custom hydrogen enclosure and tracker and see how far it gets.

I also found this blog: https://www.theastroimager.com/picoballoning/pico-ballooning.... His balloon JR14 flew for 507 days and made 6 laps of the earth which is pretty wild.
