I honestly think that in whatever type of scenario having a fully hidden, self sufficient bunker is invaluable. I will outline a few of my ideas and would like some feedback. Cost is not a factor in this analysis. I plan for this system to be approximately 75-200k sq feet.
Power:
I think the best source of power for this system would be geothermal power. Of course this limits the location of the system but I will position the system in a region with high levels of geothermal activity. Geothermal power systems do have a higher initial start-up cost but once they are up and running they require no effort to supply power/heat. This is much better than gathering fuel to power a system or relying on windy or sunny weather. The maintenance on such system is minimal.
Oxygen Production:
I have always had an issue with bunkers relying on external air to supply breathable air. Such systems can always be compromised is some fashion and can lead to detection of the bunker. Think of the exhaust from your system showing up on infrared cameras for example. An easy way to compromise your system if you rely on external air would be to simple block all the intake vents. Even if you have air filtration systems to filter out poisons etc. a 100% blockage of your air will result in a compromised situation. My solution to this problem is using plants to produce oxygen. I have taken some of this idea from this link. http://preparednesspro.com/underground-gardening-literally/ I think that if the bunker has its own well, with an infinite supply of power from the geothermal generator, and a healthy (20 year+) supply of grow lights this could be very viable. Hydroponics or aquaponics systems could be feasible.
Food production:
With an assortment of the above named systems I would want two (2) one acre grow rooms. Each of these rooms would have absolute climate control capabilities to provide specific climates to best suit particular plant species. Chill hour capabilities would be provided for specific species necessary for food production. Along side fish production from aquaponics systems I would also consider raising a few basic types of livestock. Chickens, rabbits, or goats could work well and live in the grow rooms. Keep sexes separated at all times to prevent breeding unless you are in an extended lockdown situation. These rooms would also be connected to the air circulation system to provide essential oxygen for breathing.
Shop and Mechanics:
This system would include a general mechanics shop. Welding, simple metal fabrication, motor repair, tools, and the basics needed for system maintenance. This system would not keep a large number of vehicles underground. The purpose for all vehicles stored there would be in the extreme event that all surface structures and defenses were to fail.
Rec Room:
I would like to have a full recreation room with many features. Sporting equipment, fitness equipment, a lap pool etc.
Living Quarters:
This section does not need much input as everyone has their own taste and preference. However I would aim to create as much of a natural feel as possible. This would be nothing like living in large corrugated pipes or shipping containers.
Hobbies:
A printing press, wood carving, knitting, weaving, etc. Many different practical things to do with free time will in a lockdown situation.
Vault/Armory/Security Room
The system would include a high scale vault for storing valuables, guns, and ammo. This room would also contain a small gunsmith shop with tools for fabrication and repair. Ammo production capabilities would also be included. The security room would be the nerve center of the bunker. It would be the only room in the whole bunker connected to the outside world in any way. I will have shortwave radio, satellite, radar, long range capabilities for outside communication and monitoring. All outside communication will be routed to one standalone computer system to prevent hacking into the main bunker systems. Also full day, night, infrared cameras of aboveground activity will be routed to the security room. This room will also monitor all critical systems in the bunker; oxygen levels, temperature, power supply etc.
Escape:
The system will be outfitted with multiple one and two way use alternate entrances/exits.
Main Entrance:
My main idea is to have a well disguised entrance that opens into a 10 ft square tunnel. At the end of the 50-100 ft horizontal tunnel would be a vertical shaft. This shaft would be 15 ft sq and descend 50-75 ft. The shaft would contain a platform elevator the same size as the shaft. (think aircraft carrier) At the bottom of the shaft would be blast doors leading to various parts of the facility. The main security for the whole facility is that when the elevator is at the bottom the whole elevator shaft can be filled with water to prevent anyone from entering. Multiple pressurized doors can prevent any water accidents from causing severe damage. Also the shaft does not need to be filled at all times. It is simple an extra security measure. No one attempting to enter your bunker will think to bring/or have scuba gear. And if they swim to the bottom they still wont be able to get in. Additional security measures will be included.
Please give me some feedback. This is my first post on the site.
Thanks.
