It's a great idea, the issue is scalability. To have an aquatic farm that touches the bottom, you could only use the ocean area with depths between 20 and 200 feet. Higher than that, and you have surface turbulence. Lower than that, and there is not enough light for lots of plants or fish. That narrow range of depths is a small sliver along our coasts. An area the size of Washington state, as mentioned in the article, between 20-200 feet, (without doing the math) would probably run along the entire west coast of the U.S. (assuming you could overcome the political hurdles of coastal development). To make it scalable, the farms must be able to function in the open ocean, regardless of depth. If he could figure that out, it would truly be an aquatic revolution.
