Ascend is a construction vehicle designed to reimagine how large-scale architecture is built. It uses a 3D printing style approach to construct skyscrapers layer by layer. The unique 3-box design allows the components that make up concrete—gravel, sand, and cement—to be mixed with the water from the truck's hydrogen fuel cell power plant, then be extruded. The truck is modular, so a transport version takes a container full of the raw materials from the quarry to the construction site where they can be hoisted up to a second truck to be mixed and extruded as the truck “prints” the building.
