His service pipes are the main one. look at all the military silos and they run most of the pipes up via the access tunnel. He drills them out the side and runs half a dozen PVC pipes out in random directions with 90deg bends. That's great until nuclear ground slap breaks them all (admittedly this is an unlikely scenario) but it's still a pointless and unfixable leak risk and a long term maintenance issue. Then there is the lack of defence, basically closing the hatch and hoping nobody notices the air pipes sticking up (and very few of his customers appear to have realised you need to conceal these). If the hatch had openable gun slits then you'd be able to clear your perimeter His blast valve vents into the same air space as his generator pod, these should be totally isolated systems He's installing inverter/battery systems in the same pod, again these need to be separate There are primary air systems that never get mentioned like CO2 scrubbers, presumably he thinks people are going to run their air filter the whole time the bombs are dropping. I think his pre-filter is going to clog up fairly quickly. If there was a firestorm outside then he's got no plan for cooling the intake air either. There's no way to change the pre filter without exposing the intake pipe The shower area is open to the rest of the bunker, this isn't suitable for decontamination It's an open toilet, this wouldn't pass code either. I'd be interested to see what happens in there where his U bend water evaporates after a month and it creates an open pipe to the leach field. no systems to deal with humidity or manually isolating any of the air pipes no air monitoring for radiation/CO/volatile gases no CCTV no radio comms no apparent heating systems now you could add these later, but it's not his customers job to know they will need these things, it's his. It looks like a bomb shelter, but its not really, it's just a bit of a LARP Then there is the construction, lots of last minute welds which don't appear to be inspected, just quickly slapped over with tar. unsupported air pipes The bunker still looks like a cow field on the day it's handed over to the client That awful trailer park interior and porn audition couch almost none of his clients have thought through some likely scenarios, like what if BLM turns up at 3:00am, are you supposed to troop out into the garden and climb in? what if it's a pandemic, how are you going to test the air quality without just opening the door. what if it's a long term civil unrest, how do you come and go without it being obvious you just jumped down a hole in the middle of the lawn If its in the middle of a field, where do you leave your car so it doesn't look odd, because nobody is walking anywhere if SHTF he's not offering a solid solution here, he's just making an affordable box with an NBC filter and a couch. Bill Gates definitely went elsewhere for all of his.
