Diving in Raja Ampat, Hawaii, Great Barrier Reef, Phillipines, Aruba, Bonaire, Curacao, and anyplace else with a reef system. Bonne Terre Mine if I have a dry suit.
Build a solar powered trimiran to travel to most of the above.
Teach others with a love of water who had a really shitty childhood how to dive and hand them the equipment so they can experienced the underwater world.
