WEBVTT Kind: captions Language: en 00:00:04.060 --> 00:00:09.300 Our ocean covers 70% of the Earth's surface, but currently accounts for only 00:00:09.300 --> 00:00:15.420 2% of human food. With limited land and freshwater available for farming, people 00:00:15.420 --> 00:00:18.900 are looking to other sustainable solutions to feed a growing world 00:00:18.900 --> 00:00:23.490 population. What if we could farm the open ocean, the 00:00:23.490 --> 00:00:29.310 home of ferocious storms and giant waves? To do that it would take some serious 00:00:29.310 --> 00:00:30.240 high-tech. 00:00:34.680 --> 00:00:37.900 This robot, which crawls along the netting of a fish pen to clean it, 00:00:38.100 --> 00:00:42.660 looks a bit like a space rover. So it shouldn't be surprising that Forever 00:00:42.660 --> 00:00:47.820 Oceans, a start-up company based out of Kona Hawai'i, has a background in space 00:00:47.820 --> 00:00:53.039 tech. Outer space is a terribly unforgiving environment. You've got to 00:00:53.039 --> 00:00:57.690 survive phenomenally tough conditions but really is not that different from 00:00:57.690 --> 00:01:01.500 what we do in the oceans: that you're in saltwater; you're in a very destructive 00:01:01.500 --> 00:01:04.830 environment. We've got to build everything to survive the worst 00:01:04.830 --> 00:01:10.260 conditions. We just completed a number of different simulations so the results 00:01:10.260 --> 00:01:14.729 look really good. As the wave comes through we can zoom in here and we can 00:01:14.729 --> 00:01:18.210 see there's a bit of a stress concentration that happens right in the 00:01:18.210 --> 00:01:22.890 front of the cage. We use a comprehensive modeling and simulation tool to test and 00:01:22.890 --> 00:01:27.150 verify all the components that go into a Forever Oceans cage. This is similar to 00:01:27.150 --> 00:01:31.530 what you would see with a jet fighter or Space Shuttle. We use real-world storm 00:01:31.530 --> 00:01:36.180 conditions so what you're looking at here is similar to hurricane Iniki 00:01:36.180 --> 00:01:41.280 that Hawai'i saw a number of years ago here, rolled directly over a wave buoy. We 00:01:41.280 --> 00:01:45.270 incorporate that data into the models. The tool not only allows us to verify 00:01:45.270 --> 00:01:49.740 our current designs but allows us to quickly develop new open ocean gauge 00:01:49.740 --> 00:01:55.470 technology for storms of the future. This simulation shows a Forever Oceans fish 00:01:55.470 --> 00:01:58.600 cage placed in deep offshore water. 00:01:59.160 --> 00:02:02.460 These cages can hold 700 tons of fish, 00:02:02.740 --> 00:02:04.840 like these Amberjack. 00:02:04.840 --> 00:02:09.100 These high-tech fish pens can be submerged under the 00:02:09.260 --> 00:02:15.410 water during big storms to avoid destructive waves. Shorelines can be a 00:02:15.410 --> 00:02:20.330 very popular place, so sighting offshore helps these farms avoid shipping lanes 00:02:20.330 --> 00:02:25.130 and crowded areas. Since they're so far offshore the systems can be fully 00:02:25.130 --> 00:02:29.930 automated and controllable from land. Inside the container behind me you see 00:02:29.930 --> 00:02:33.800 one of our command and control units. It's essentially an entire data center 00:02:33.800 --> 00:02:38.120 inside. It controls every aspect of the husbandry from the feeding to the 00:02:38.120 --> 00:02:42.980 cleaning to the removal of fish. We're good. Turning on water now. Water is coming on. 00:02:43.600 --> 00:02:45.240 Looks good. Perfect. 00:02:46.040 --> 00:02:49.600 It's transformative when we talk about being able to take out your cell phone and 00:02:49.600 --> 00:02:53.530 control robots that are 20 miles offshore in the middle of the ocean. 00:02:53.530 --> 00:02:59.180 That's what this system gives us the power to do and that changes how we can 00:02:59.180 --> 00:03:04.010 conduct aquaculture. On the robotics and manipulators the high-end sensors all 00:03:04.010 --> 00:03:09.890 those equip us to operate in a better location in nature in deeper waters, and 00:03:09.890 --> 00:03:13.880 operate in a manner that allows conservationists like myself as well as 00:03:13.880 --> 00:03:18.110 a general public, to sleep well at night knowing you're being fed by the ocean in 00:03:18.110 --> 00:03:25.040 a sustainable manner. In fact the U.S. exclusive economic zone spans 13,000 00:03:25.040 --> 00:03:31.299 miles of coastline, but contains 3.4 million square nautical miles of ocean– 00:03:31.299 --> 00:03:37.580 larger than the combined land area of all 50 states. So there is indeed plenty 00:03:37.580 --> 00:03:40.970 of open ocean available for remote-controlled fish farms to grow 00:03:40.970 --> 00:03:45.640 food while also keeping our ocean healthy and clean.
