New Podcast Episode: Flying Boats and Underwater Drones

Dear Rational Optimist,

I recently spoke with two young founders driving the ocean’s future: Will O'Brien from Ulysses Ecosystem Engineering and David Zagaynov from Poseidon Aerospace. They’re building high-tech flying boats and underwater drones while stewarding the ocean.

In our interview you’ll hear about:

• Why Poseidon’s flying boats could revolutionize cargo transport

• The billions in gold and emeralds sitting in one wreck off Colombia's coast

• How underwater drones are solving critical problems, from seagrass restoration to defense

• How Starlink and advances in EV batteries are enabling big leaps in autonomous ocean vehicles

• The biggest gaps in the “ocean stack” … and who’s going to make all the money
