Participants in the Pamphlet Architecture 30 competition were asked to respond to the theme "Investigations in Infrastructure," and propose new directions for architecture, transportation, energy, cities, and agriculture at a continental scale. The winning entry, Coupling, imagined six daring projects: a high-speed rail system across the Bering Strait that also collects freshwater from the seasonal iceshelf; a decommissioned airport transformed into a geothermal data farm and agriculture site; thickening on/off ramps around "big box" stores into circular parking lots; a call to include landfills in the list of preserved open spaces; and a saline terminal lake turned into a water farm, recreational retreat, and habitat haven. Coupling argues that infrastructures behave as artificially maintained natural systems. Rather than a New Deal approach of massive engineering or iconic infrastructure, Coupling employs adaptable, responsive, small-scale interventions whose impacts are global in scale
