As we've already seen from Bill Gates, while earning your money through entertainment might be the more glamorous route, if you want to be a multi-billionaire, then the way to get there is through technology. Larry Page co-founded Google. Everybody uses Google every day. The company is worth $136bn, with Page's own net worth coming in at north of $55bn. That's enough money to see him move into the Virgin Islands, next door to fellow billionaire Richard Branson.
Page has put his love of technology to good use at Eustatia Island. It's an eco-friendly tropical paradise which is completely solar-powered. We suppose that's easier to achieve when you're living somewhere the sun never sets! Page doesn't spend all year there, and he even lets visitors come to spend time with him in the villas he's had constructed for rental purposes. We don't know how much they cost, but we're going to wager that it's a lot.
