Oracle billionaire Larry Ellison has moved to Lanai, the Hawaiian island he's spent half a billion dollars developing. Here's how Ellison bought 98% of the island and turned it into a sustainability experiment.

• Oracle billionaire Larry Ellison bought 98% of the island of Lanai in 2012 for an estimated $300 million.
• Since then, he's worked to make it a tourist destination, including purchasing budget airline Island Air to ferry passengers from Oahu to Lanai. (He has since sold a controlling interest in the airline).
• Ellison is also hoping to turn Lanai into a wellness utopia. He launched a new company called Sensei, which has two main projects: a hydroponic farm powered by Tesla solar panels, and a luxury spa called Sensei Retreat. Sensei's goal is to use data to help people lead healthier and longer lives.
• In the early months of the coronavirus pandemic, Ellison — who's worth an estimated $75 billion — paid wages and benefits for his Lanai employees.
• Now, Ellison has moved to Lanai full time and plans to use "the power of Zoom to work" from the island, he told Oracle employees this week.

Ellison revealed this week that he has moved to Lanai, Hawaii, amid the coronavirus pandemic. He plans to use "the power of Zoom to work" from the island, he wrote in an email to Oracle employees, who had been asking about Ellison's plans in the wake of Oracle moving its headquarters to Austin, Texas.

Ellison owns almost the entirety of Lanai: He purchased nearly 98% of the island in 2012 for a reported $300 million - his purchase included 87,000 of the island's 90,000 acres of land.

Lanai, which is home to about 3,200 residents, is the smallest inhabited island in Hawaii and is home to serene beaches, rugged terrain, high-end resorts, and Ellison's sustainability ambitions, which he's executing through a development company called Pulama Lanai.

Here's how Lanai came to be owned by Ellison and what he's planning for the island.

In June 2012, Ellison bought Lanai for an estimated $300 million. Prior to Ellison's purchase, the island was owned by billionaire Dole chairman David Murdock, who had reportedly been asking for $1 billion for the island.

Murdock became the owner of Lanai in 1985 after taking over Dole's parent company, Castle & Cooke. Prior to Murdock's ownership, the island was controlled by "Pineapple King" James Dole.

The 141-square-mile island, which is eight miles off the coast of Maui, has zero traffic lights and few paved roads, according to Forbes. Compared with other Hawaiian islands, Lanai is secluded - but Ellison has plans to change that: He wants to turn Lanai into a tourist destination.

The island was also home to two golf courses when Ellison bought it, including Manele Golf Course. In 1994, prior to Ellison's ownership of the island, Microsoft cofounder Bill Gates got married at the 17th hole of the course.

The other course, Koele, was designed by golfer Greg Norman. The course has since been shut down, and an adventure park and zipline have been installed in its place.

In 2014, Ellison bought Island Air, a budget airline that ferries passengers from Oahu to Maui and Lanai. But two years later, after the airline lost $21.78 million and had to lay off roughly 20% of its workforce, Ellison sold a controlling interest in the airline.

Ellison's Lanai purchase included an animal-rescue center. Because there are no natural predators to cats on Lanai, the feral-cat population at the shelter has ballooned to over 400 cats (which Ellison technically owns). In recent years, it's become a travel destination in itself.

Ellison's ambitions extend beyond tourism, however: he plans to create "the first economically viable, 100 percent green community," according to The New York Times.

In 2018, Ellison launched a wellness company called Sensei, which is working on three main issues: global food supply, nutrition, and sustainability. Sensei's goal is to use data to help people lead healthier and longer lives.

Sensei built two 20,000-square-foot hydroponic greenhouses, known as Sensei Farms. The greenhouses have sensors and cameras that track data about the farms, including water usage and airflow. According to Forbes, they're powered by 1,600 Tesla solar panels (Ellison sits on Tesla's board).

Sensei also built a luxury spa called Sensei Retreat that costs $3,000 a night. Guests set physical and mental goals for their stay and the spa tracks their sleep, nutrition, and blood flow. The heirloom tomatoes and cucumbers grown at Sensei Farms are used at the spa's in-house Nobu restaurant, according to Forbes.

Ellison reportedly wants to purchase the island's power plant and electric grid from Hawaiian Electric Co. to transition the island away from fossil fuels toward 100% renewable energy.

Ellison's goal is for Lanai to serve as a prototype for a "health utopia," according to Forbes. Tesla CEO and Ellison's close friend Elon Musk told Forbes that Lanai is like "a microcosm for the world."

When the coronavirus pandemic struck Lanai this year, Ellison reduced or eliminated rent altogether for businesses on the island and paid the full wages and benefits for employees who worked for him.

All told, Ellison has spent roughly half a billion dollars on the island, beyond his initial purchase (in 2014, he spent $41 million on property alone). But Ellison's wealth has only continued to rise during the pandemic: These days, he's worth an estimated $75.2 billion.
