Will the cities we live in become uninhabitable due to climate change, overpopulation and other factors that lie in our future? If so, should we be investing in floating cities now to solve this problem? What might they look and sound like? We meet the so-called Aquapreneurs and Seavangelists crafting models for these floating habitats. They have ambitious, yet dramatically different theories to solve these not-so-distant problems. Ship scientist Philip Wilson puts their futuristic ideas to the test, along with the plans of our “mystery floaters”.
