Picture: BLOOMBERG Singapore — A nuclear-powered ship full of scientists, activists and billionaires sailing the world and examining the state of the oceans. That is the dream of entrepreneur Aaron Olivera, who believes the novel vessel will help raise environmental awareness. The ship, called Earth 300, was designed by superyacht specialist Ivan Salas Jefferson. Almost 300m long and 60m high, it will be able to accommodate 425 people. Most of those will be staff, scientists and students, travelling for free. A handful of wealthy tourists, housed in luxury suites, will pay $3m each for a 10-day journey — helping to make the venture profitable.
