Prism: 2022 Onwards

In July 2022, I was asked to join a group planning to build a new type of underwater habitat. This is to be based near a coral reef, 10-15m deep, somewhere in the archipelago of islands round Indonesia, Borneo and the Philippines. The structure consists of approximately 150m2 of accommodation, mostly kept at 1 atmosphere, so it has to be a pressure vessel. There is an airlock to a moonpool section so divers can exit for excursions. A significant proportion of the habitat comprises of acrylic cylinders over 3m in diameter. The plan is for 5 people to spend up to 25 days without any re-supply.  The plan is to start building in the second half of 2023.
