Damn Rich People: Anthénea Autonomous Luxury Floating Ocean Pods

These are the Anthénea luxury floating sea pods. Each eco-friendly pod can be configured with between one and three guest rooms, each with its own kitchenette and bathroom, and “features solar panels, a popup solarium roof for dining, 360° water views with an underwater observatory, and smart home automation.” They cost between $300,000 and $500,000 depending on the model and options chosen (including 3 or 6 day autonomy). Obviously– “You will never own one.” Because I have taste and decency. “And not $300,000 to $500,000.” I mean that too, sure.
