The following year, Gamberini, a self-declared “explorer of all things ocean,” devoted part of the budget of his family-owned business, Ocean Reef, to fund the first fully functional underwater farm. It was a matter of personal curiosity: “I want to find out if underwater farming can become a suitable alternative during my lifetime,” he says. He also hopes that if underwater farming takes off, he’ll be the one holding the patented technology.
Sounds like a neat project, but it doesn't look like it will scale or be sustainable in the near future unless more of it is somehow automated.
