2 . You are just waking up in the spring of 2030. Your Internet of Things bedroom opens solar-powered e-windows and plays gentle music while your smart lighting displays a montage(蒙太奇) of beachfront sunrises from your recent vacation.

Your shower uses very little water or soap. It recycles your grey water and puts the extra heat back into your home's integrated operating system. While you dress, your artificial intelligence (Al) assistant shares your schedule for the day and plays your favourite tunes.

You still start your day with caffeine but it comes from your loT refrigerator which is capable of providing a coffeehouse experience in your home. A hot breakfast tailored to your specific nutritional needs (based on chemical analysis from your trips to the "smart toilet") is waiting for you in the kitchen.

When it's time to leave, an on-demand transport system has three cars waiting for you, your spouse and your kids. On the road, driverless cars and trucks move with mathematical precision, without traffic jams. Accident rates are near zero.

En route, you call your R&.D team, who are wrapping up a day's work in Shanghai. Your life-sized image will be projected,which makes your colleagues see you as if you were sitting with them. It's a bit surreal(超现实的)for them to see you in the morning light given that it's dark on the Bund, Shanghai's waterfront, though the novelty fades after a few uses.

You review the day's cloud-based data from your Shenzhen manufacturing centre, your pilot project in San Diego, and your QA team in Melbourne. The massive datasets are collected in realtime from every piece of equipment and have been beautifully summarized by your company's AI. All these facilities are closely maintained and operated via a skilled predictive analytics platform. Pleased with the team's progress, you end the call and ease into a good book. This is the future and it will be here sooner than you think.

3 . The sea could be the food bowl of the future. In Jervis Bay, south of Sydney, seaweed, which is rich in fibre and omega 3, is grown and harvested.

Pia Winberg is a marine scientist who runs Australia's first food-grade fanned seaweed company. Her crop is grown alongside mussels (贻贝)and is used as an additive in pasta (意大利面)and other products.

Seaweed is also raised in large tanks, where it absorbs carbon dioxide waste from a wheat processing factory. The business is small, but could help to reduce the ecological footprint of traditional farming.

“We used ten percent of seaweed instead of wheat in breads and pastas, we've eliminated a million hectares of land, we've eliminated all of the carbon dioxide emissions associated with that, and we've also reduced the pressures on very precious fresh water.” said Pia Winberg.

Spiny sea urchins (多刺海胆虫)are another blue economy resource. They can destroy marine habitats, but a recent competition for environmental start-ups in Australia, saw them not as a pest but a delicacy (美味).

Martina Doblin, CEO of Sydney Institute of Marine Science, said, “By 2050 we will have some ten billion people on the planet, and about half the food they eat will come from the ocean. So, we really do need to pay attention to the way that we manage the blue economy-generating wealth from the ocean but in a sustainable (可持续的)way.”

Farming at sea has its challenges. Infrastructure (基础设施)has to be sound, as do supply chains and biosecurity. But get these things right, and the ocean might just be the next great economic frontier.
