I am not down on the cruise industry. I am not down on Cargill. I am not down on the United States Army. When you see things go awry in your lifetime, it is your responsibility to speak up. Democracy fails when good men do nothing. Of what do I speak? If Fidel Castro's communist takeover of Cuba closed their borders to America, then Cuba's reopening to the world is a significant event. An industry who capitalizes on travel by sea would be in an opportune position to exploit this political treaty. We have Barak Obama to thank for that, the re-opening of Cuba doors to travelers circa 2016, when "The Havana Syndrome" first upon which was reported. The civil employees in the American Embassy just down the boulevard from the cruise terminal were first to complain about the effects of infrasound. A few studies were done and an Asian scientist reverse engineered the noise that was recorded. It was fighter jet emissions or more likely ultrasound. Add one plus two, multiple diesel electric prime movers hiding in the hulls of newly positioned cruise ships, and military aircraft noise and what may you get? Something most people won't understand. This refusal to acknowledge that because something is invisible to our sight means it isn't possible is naive. Because you can't see something it does not exist. Trumptistas have been exploiting this angle for two decades. Deny science. It was an easy tunnel for corporate America to do whatever they wanted no matter the circumstances for the American people. More political events have transpired, and with the recognized "Technology Boom" of Google and everyone else, there are more wireless, microwave-based, pulsed energy devices than ever. This description is what must pundits have said was the most likely source of "The Havana Syndrome." Pulsed microwave energy. Pulsed microwave energy has been the source of the technological boom, since Bill Clinton auctioned these frequencies to balance the federal budget. There are a myriad of sources for this energy not to mention the Washington-based intelligence community and the U.S military. When the FBI and CIA hedge on the probable source of the malady, you might deduce it may be their activity that is the cause. I know a little about the cruise industry, because I worked in it for a decade. I will tell you that ships without "Azipods" are more comfortable than ships with them. The reason is is an azipod is a huge AC drive under the water. It hums and it is hot. The ocean acts as a cooling tower, but it doesn't appreciate the extra duty. Neither does the rest of the marine life nor our coral reefs which are dying. The oceans are getting hotter and guess why? Again I am not down on the cruise industry, but I don't like azipods. The very first azipod-equipped ship for Carnival was the Paradise, and it propulsion units were under the bow. When I played production shows in the theater, the stage shook violently most of the time. It took a while to get used to it. Fully I understand and appreciate the novelty of a 360 degree rotating propeller pulling the ship through the water, but.... The compromise is the smoothness of the boat ride and its emissions. How could an azipod be anything other than wonderful for the cruise industry? Add the financial set back of 2008 to the list, and suddenly ships were traveling much slower. These AC drives now were operating in the LF range, which means these units were producing low frequency alternating current. This electricity was underwater, much to the "shock" of the marine life. There also is a rotating magnetic field, heat, and vibration. These things are not helpful to creatures beneath the sea. Jump ahead and imagine that most railroads have converted to AC traction. There are AC drives in the ocean and all over the continental United States and the rest of the world. Take infrasonic emissions from the firing rate of a diesel prime mover and add these to low frequency alternating current, and you may have the end of the planet. Let's hope not.
