1. Silo cap
The only thing visible aboveground is a
concrete cap with blast-proof windows, built to withstand a shock wave traveling more than 2,000 miles an hour—about what a nuclear detonation would
produce. “We could sit under here looking through bulletproof glass more than four inches thick and watch an F5 tornado go by,” Hall says.
2. Food
The silo will store
vegetables grown in soil-free trays and fish farmed in tanks, cultivated at a former launch-control site nearby. Connected to the silo by tunnel, the adjacent facility could supply food for up to 70 people
indefinitely. Employees will normally tend the food, but in lockdown, residents will maintain food, water, and other necessities themselves.
3. Living spaces
Luxury apartments will have brand-name kitchen appliances and jet Jacuzzis in master bedrooms. To compensate for the lack of a view, occupants can enjoy scenery of their choosing, be it San Francisco Bay or a tropical aquarium, on large, window-like HDTV panels. The “windows” dim in the evening to help make life seem at least semi-normal.
4. Lockdown
If the world is destroyed, two deep wells and a rainwater collection system will feed purified water into the silo. A diesel generator and wind turbine will supply electricity. Air will be piped in through nuclear, biological, and chemical contaminant filters. The silo will be surrounded by electric fencing and security cameras and will have its own weapons arsenal.
5. Entertainment
Sure, residents will have home TV and Internet access. But gathering places—including a movie theater, bar, general store, classroom, pool, and
fitness center—will promote socializing and cooperation. Until the apocalypse, residents will be able to drive 35 miles into downtown Beloit, a town of 3,800 people, with restaurants, movie theaters, and an airport.
