Soleri proposed later solutions, and coined the term "arcology". Soleri describes ways of compacting city structures in three dimensions to combat two-dimensional urban sprawl, to economize on transportation and other energy uses. Like Wright, Soleri proposed changes in transportation, agriculture, and commerce. Soleri explored reductions in resource consumption and duplication, land reclamation; he also proposed to eliminate most private transportation. He advocated for greater "frugality" and favored greater use of shared social resources, including public transit (and public libraries). Similar real-world projects Arcosanti is an experimental "arcology prototype", a demonstration project under construction in central Arizona since 1970. Designed by Paolo Soleri, its primary purpose is to demonstrate Soleri's personal designs, his application of principles of arcology to create a pedestrian-friendly urban form. Many cities in the world have proposed projects adhering to the design principles of the arcology concept, like Tokyo, and Dongtan near Shanghai. The Dongtan project may have collapsed, and it failed to open for the Shanghai World Expo in 2010. McMurdo Station of the United States Antarctic Program and other scientific research stations on Antarctica resemble the popular conception of an arcology as a technologically advanced, relatively self-sufficient human community. The Antarctic research base provides living and entertainment amenities for roughly 3,000 staff who visit each year. Its remoteness and the measures needed to protect its population from the harsh environment give it an insular character. The station is not self-sufficientthe U.S. military delivers 30,000 cubic metres (8,000,000 US gal) of fuel and of supplies and equipment yearly through its Operation Deep Freeze resupply effortbut it is isolated from conventional support networks. Under international treaty, it must avoid damage to the surrounding ecosystem. Begich Towers operates like a small-scale arcology encompassing nearly all of the population of Whittier, Alaska. The building contains residential housing as well as a police station, grocery, and municipal offices. Whittier once boasted a second structure known as the Buckner Building. The Buckner Building still stands but was deemed unfit for habitation after the 1969 earthquake. The Line (Arabic: ذا لاين) is a long and wide linear smart city under construction in Saudi Arabia in Neom, Tabuk Province, which is designed to have no cars, streets or carbon emissions. The Line is planned to be the first development in Neom, a $500 billion project. The city's plans anticipate a population of 9 million. Excavation work had started along the entire length of
