On the quiet coast off the traditional territory of the Squamish people in British Columbia, a retired Canadian warship lies moored in the still waters of Burrard Inlet. Once a Bay-class minesweeper, she braved Arctic ice and Pacific storms, serving the Canadian Navy through tense decades of the Cold War. Today, her mission has shifted dramatically: she grows food.

Inside her steel hull, the armory has been cleared, sailors’ bunks disinfected, and reflective film laid along the walls. Rows of vertical racks glow with violet LED light, cradling lettuces, cherry tomatoes, and bright red peppers. What was once a machine of war has been reborn as a floating vertical farm, a vessel now committed not to combat but to sustenance, resilience, and innovation.

A start-up presented its newest prototype of a floating greenhouse, where vegetables can be grown on a plantation without soil, as footage filmed in Almere on Wednesday shows.
