http://www.vimeo.com/8479737 THE RETURN OF THE OVUM PROLOGUE HISTORY In 2020, countries such as Canada, cities like the City of Vancouver, succeeded in reducing much of their greenhouse gases. Despite efforts to slow global warming, the 10 year period earlier established by experts from IFREMER (France) and the IPCC proved to be too optimistic. The belt of the Atlantic stopped, starting a chain of events which led to the Ice Age. In 2030, the ovum are now organizing into renewed and dynamic autarchic settlements, despite the foul air and harsh environmental conditions. Vancouver lies under a white rubbery substance and serves as a museum to the brave settlers. SUSTAINABLE TREE-LIKE CITY Trees have disappeared, but the mother ship ovum, a nursery building next to the airport, has successfully emulated a tree-like organic structure, a project inspired by biomimicry. It hatches ovum that become mountains at maturity and can harbour cities with dwellings, business, commercial and recreational centres, designated green zones and urban transport infrastructures at the core. Public and private shuttles called « pods » travel from one ovum-city to another leaving its cargo at the base of an ovum where it can "fill up" with solar energy. Cities can be moved to any area, ground or water. FUNCTIONAL ARCHITECTURE Promoting high density, the city prioritizes the well-being of all citizens; greenhouses provide agriculture and recreation. Dwellings are designed autonomous bubbles adapting to outside and inside climatic modulations. Heat, ventilation and central air conditioning are controlled artificially by a system called "interior weather", an ethical approach invented by Swiss architect Philippe Rahm. Exploring the metaphor of a tree, the architecture made of molecular space alloy harnesses energy from the sun (solar membranes), air (built-in gigantic wind turbines), earth and water (a structure-like roots and retractable anchors carry heat from its geothermal reservoir) and new nano and terraformation technologies.
