Kho Jian, a metalworker from Louhe in Henan province, central China, is designing and building the craft using re-salvaged and converted oil tanks. The ‘Noah’s Ark’ will come at a cost of £20,000, and will be fitted with a range of mod-cons including a kitchen and bathrooms. It will also use technology that is employed for space travel in order to keep it watertight – while also providing doors and windows.
