Thank you for that one about the waves, I forgot about it. But it intrigues me because I just read an article about a Company who made the biggest Cruise ships ever, but stopped, sent them to the scrap heap because they said they will now be focusing everything on making Submarines. Seemed weird at the time, but now makes me happy I can daydream about one of my favorites, Hollow Earth/subterranean Societies and/or the planned in advanced bunkers for the upcoming solar killer/asteroid/Nuclear destruction they have know about for years & have been preparing for.
