This site has proposed new domed city plans before.
Nextbigfuture has tried to show that dome cities can be made profitably and that they can provide energy efficiency and other benefits. Examples were provided of large EFTE (superstrong and light teflon) and aluminum structures that provide climate control for the interior structures and current largest examples of geodesic domes. An EFTE Geodesic dome can probably be brought down to $3-5 million per acre in cost. However, even $10-20 million per acre domes can be very profitable. Domes can make buildings inside more economical by reducing the need to heat or cool them. The Dome themselves can leverage atmospheric and other effects to maintain constant internal climate and generate power. The domes can use vents and can have a large chimney for airflow and even more temperature control.
Temcor Aluminum Domes are unique and patented triangulated space truss skinned with aluminum panels secured by a patented Temcor batten closure system. Temcor has built 7000 domes it the several hundred feet to one thousand feet in diameter size range. With an ability to cover spans from 40 to more than 1000 feet, Temcor Aluminum Domes are specified for churches, arenas, planetariums and observatories… wherever clear-span roof systems are needed. The conventional construction of the large (up to 1000 foot or 300 meter diameter) geodesic domes is with a tower about twice as tall as the final height of the dome. China has built a hyperboloid tower of 612 meters in height for $324 million.
The project would be located inside a giant man-made crater of more than one kilometer in diameter and 550 meters deep that used to be one of the world’s largest quarries. The idea is to create a new garden city that will be shielded from the harsh Siberian environmental conditions characterized by long and severe winters and short hot summers. The new city would attract tourists and residents to Eastern Siberia and would be able to accommodate more than 100,000 people. The new city is planned to be divided in 3 main levels with a vertical farm, forests, residences, and recreational areas. On of the most interesting aspects of the proposal is the glass dome that will protect the city and would be covered by photovoltaic cells that will harvest enough solar energy for the new development. A central core houses the majority of the vertical circulations and infrastructure along with a multi-level research center. The housing area is located in the first level with outdoor terraces overlooking a forest in the center of the city. The idea is to create a new type of highly dense urbanism in harmony with nature.
