Floating Farm To Grow Food On Cargo Ships Returning Empty

About 90% of the world’s goods are carried by sea, with more than 705 in shipping containers carrying everything from TVs to sportswear from Asia to the rest of the world. But the global imbalance in trade means most of these containers are empty on the return journey. Design student from RCA, has devised a way to stop this empty space going to waste. Grow Frame is a collapsible hydroponic farm that could grow vegetables inside the empty containers during the weeks-long sea voyage. Grow Frame tackles the challenge that half of all containers going to China are empty. And that means, right now, 13 million containers annually are traveling around with just air. And when researcher heard about that he thought that’s not a problem, that’s an opportunity.

Each plant is grown in small individual plastic bags containing all the water and nutrients needed to feed the plant during the trip. The mini farms would cultivate vegetables using battery powered LED lights that can be adjusted to provide precisely the right spectrum of light for optimal growth. Researcher said the energy efficient lights and the battery would hold enough power for the duration of the voyage; for example, for the approximately three weeks it takes for the vessel to travel from the UK to China. To keep the climate inside each container as natural as possible, he said he’s planning to grow mushrooms with leafy vegetables to help balance the mini ecosystem.
