“Bill Gates has ordered the world’s first hydrogen-powered superyacht, worth an estimated £500m ($644m) and boasting an infinity pool, helipad, spa and gym.”

“The boat boasts five decks, and with space to accommodate 14 guests and 31 crew members. In a further environmentally friendly feature, gel-fuelled fire bowls allow guests to stay warm outside without having to burn wood or coals. But its most cutting-edge feature is tucked away below decks - two 28-tonne vacuum-sealed tanks that are cooled to -423F (-253C) and filled with liquid hydrogen which powers the ship. The fuel will generate power for the two one-megawatt motors and propellors via on-board fuel cells, which combine hydrogen with oxygen to produce electricity. Water is a by-product.”
