Bill Gates, known for his sustainable energy initiatives, commissioned a groundbreaking superyacht named Breakthrough powered by liquid hydrogen. The $645 million vessel, with emissions-free energy and novel hydrogen fuel cells, completed its sea trials near Amsterdam and is set to be sold after Gates declined ownership. This superyacht, a first in fuel-cell propulsion, boasts luxurious amenities including a library, movie theater, basketball court, pool, and onboard hospital. The decision not to purchase the yacht, despite Gates' estimated $160 billion net worth, raises questions about its future ownership and the significance of this fuel-cell achievement in the luxury yachting industry. While the vessel represents a triumph in green technology, the high price tag poses a challenge in finding buyers who can afford the environmentally advanced Breakthrough.
