We've successfully buried a massive
bunker underneath my backyard, but with that success comes a tiny
predicament. If you remember seeing the giant culvert bunker tubes flying through
the air as we lowered them into the hole we dug in my backyard. Those tubes had a black
exterior waterproofing coating on the outside that helps keep the metal intact while
it's underground for the next 100 years. That coating however burns away if we do
any welding on the inside wall of the tube, which means, now that the bunker
is 17 feet below ground we can't weld any of the inner walls to the
outer walls unless we want to dig it all up and recoat the outside. And that is
something I definitely do not want to do. I think we have a solution, however, that involves
a skeleton, so hopefully it works. And at the end of this video we should have a complete, offgrid
electrically powered, underground bunker. This dark and dingy cave needs to be transformed
into a warm and happy hobbit hole. Okey dokey. We're building out three main rooms. There's
a kitchen and living area near the entrance. Then a bunk room in the middle of the bunker,
and a main bedroom with a queen size bed in the far room near the exit shaft. All of which
are going to have lights and electrical outlets like a normal residential home or RV. All of
the welding and construction happening today is going to be underground. And sense oxygen is
rather important in an in-closed environment. We have to be careful where we get our electricity
from. Not to mention how loud an engine would be inside this large tin can. We can't very well
run a gas powered generator to power all our equipment. Gasoline has a shelf life of about 6
months anyway. So gas generators aren't the best solutions for long term apocalyptic scenarios.
We're going to be using the new EcoFlow Delta Pro 3. A solar battery powered generator that has
a working life of 4,000 cycles. Which means we should be able to run this thing everyday for
the next 11 years. Batteries have come a long way recently. This generator can output 4,000
watts which is more than enough to power the 240 volt welder. While we erect the internal
skeleton around the inner walls of the bunker. The flanges where we join the two tubes together
have enough metal mass to absorb the heat from the liquefied welded metal without burning through
to the exterior. At least that's what Im hoping, since I'm not actually going to dig up my
backyard again to check. We'll have some thick metal straps bent and tucked in
behind the long beams to keep them from shifting around. Kind of like a barrel. And then
to make this parallel with this. Inverted clamp. The inner devising walls are also going to
be built from metal. Which we just had laying around from when we started this project. Then we
might as well use it all up. Obviously, EcoFlow is probably gearing this solar generator more
towards a home backup or emergency situations, but it's good that it can handle the heavy use
of a construction site as well. We currently have the Delta Pro 3 hooked up to 800 Watts worth of
flexible solar panels outside. It can accept up to 2600 Watts or charge from a normal wall outlet,
or even a DC fast charger. And it's nice that we can run all of our equipment off of a single unit.
Cause previously in order to get 240 volts we had to pair two EcoFlows up with a cable. But this
Delta Pro 3 can do 240 all in a single unit. The first side of the wall is up. The second
side of the wall is super easy. Now for the header above the door frame. And in an actual
emergency or apocalyptic situation where a gas generator would give away your position.
This can output 2,000 Watts at under 30 Decibels. Which is about the same loudness
level as a whisper. They're calling it the X quiet technology. Not to be confused with
extinction level event. Anyone saying you need a gas generator for the apocalypse is probably
just a zombie wanting to know your location. The elevator we installed is a lifesaver for
bringing down equipment. We got a sliver already. We're going to frame out one singular
vertical wall near where the kitchen will be. This is scrap wood that I reclaimed from the
wheelchair factory. This wall will eventually hold up the biggest TV we can fit through the
door at some point. But that'll come later. One problem at a time. We are using the EcoFlow
portable battery generator to install EcoFlow's permanent RV backup power kit. Which should turn
this bunker into a home. In my humble opinion, this is the easiest to install off grid, off the
shelf, plug-and-play battery system on the planet. The offgrid power kit gives us a normal breaker
panel, normal wiring, normal outlets, and enough juice to live down here indefinitely if we need
to. As long as the sun keeps shining above ground. First try... haha. It's a little
bit of CAD cardboardaded design. That's what they.. That's what they call that. Nate: Someone needs to appreciate how
sick this is. Come on! That's pretty good. Zack: We're mounting the power kit in the
living room area. Right outside the bathroom wall. Inside the bathroom we'll have an electric
combustible toilet. And ya, you heard that right, combustible. But let's not get ahead of
ourselves. We have plenty of other problems to solve before we get to number two. We laid
a piece of white FRP behind the control panel and the inverter. FRP is fiber reinforced
plastic. Which smells terrible when cut, but looks very good. And its flexibility will
make rounding the walls of the cylinder easy when it comes time for finish work. The 5 Kilowatt
hour large stackable rectangular batteries in the power kit are permanent. There's no wheels or
anything. They just get fixtured to whatever RV, cabin, or bunker they're installed in. Oh haha, it
is smokey dude! Good thing we have the fan pulling air from the other side of the bunker. The air
is circulating quite very well, so we're safe. Nate: There's a chance that's right on a stud.
Zack: Hmmm we didn't think about that did we. Smells good though. We've been learning the hard
way that it's super easy to bury a culvert bunker, but the circular shape makes it much more
difficult to build out once it's in the ground. Luckily, the circular shape does give us
plenty of storage under the deck. We'll use this to hold the food and water. But also, we had
some uniquely designed white PVC wiring ducts. You might be saying to yourself, Hey Jerry,
that wire duct looks a whole lot like a rain gutter from Home Depot, and I would say you are
most definitely right. The gutter just keeps the wires suspended in the crawl space while providing
a very organized layout for wire management. With all the wires lifted up and off the crawl space
floor we'll still have room for a very large water bladder and months worth of food storage.
Along with plenty of books and video games. Cause, when the aliens arrive to wipe out humanity,
at least we won't be bored. All the wires run through those gutters and then up into the
walls we framed. Just like in residential construction. We've cored out large holes in the
metal wall studs with a mag-drill. The mag drill uses a very powerful electromagnet to clamp
itself onto a metal surface and brute force its way through thick pieces of material without
much human effort required. Just electricity. Romex gets pulled through metal studs and metal
conduit everyday, but we added metal grommets to the inner edges just in case. Safety is always
a good thing. And finally, all the wires come together inside of the normal breaker panel.
There are six regular AC breakers and 12 DC fuses for a seperate low voltage system. The DC
side is much more efficient than the AC side. And we'll be tapping into the DC stuff later,
but for now we're just wiring the AC. That's freakin sweet! So we're at 29% power. Probably
across both batteries. That is incredibly easy to set up. You can see the romex coming through on
one side just like a regular residential breaker panel. The 12 DC runs with their DC fuses are on
the other half. These could be 12 or 24 Volts. And we'll run these later.
She's looking pretty. Nate: So pretty you're not going
to get bullied in the comments? Zack: I don't think so. It's pretty nice. This is the kitchen run. Larger gauge.
Obviously this 10 Kilowatt power kit is very much a permanent installation and not super
portable. The Delta Pro 3, however, is extremely portable. It's 4 Kilowatt hours and also stackable
with expansion units. Each of which are also 4 Kilowatt hours. Coming. The wheels on the back
and the carrying handle make it much easier to transport and move around. The portable Delta Pro
3 has four 120 volt outlets and a 240 volt plug. Keep in mind though that the 240 and 120 will not
work at the same time. You got to pick one or the other. The Delta Pro 3, however, can plug into our
power kit and add its 4 Kilowatt hours to the 10 Kilowatt hours we have permanently installed. It's
a pretty slick setup and is pretty awesome. how well EcoFlow's products all work with each other.
It functions down to negative 10 degrees. Has a 10 millisecond UPS response time to back up servers,
router, or security cameras. And Internally it has a IP65 splash resistant battery pack. All with a 5
year warranty. We definitely aren't finished yet, but with our power source now in place it'll make
things much easier down here from now on. And if this video gets a million likes, I'll upgrade
to a fusion core. I feel like with electricity if you do it right nobody notices, but if you
do it wrong everything goes boom. Before the inspector comes though let me show you what this
thing is made from. The first thing we have is a very portable and convenient carrying handle
that allows the Delta Pro 3 to be transported very easily. We have a color LCD screen up top
and then by clicking this button here we have 4 120 volt outlets. And by clicking the button
over here we enable the 240 volt with two different styles of plugs. Enabling the 240 volt
does disable the 120. The ports on the back are all used for power distribution. Underneath the
first door, which flops down and gets tucked away, is our regular charging cable from an outlet
or the solar inputs. And the two ports on the right side are the extra battery ports for the
expansion modules. And the largest port on the back is used to connect the Delta Pro 3 to a smart
home panel 2 to back up your whole house. And in our last sliding door we have the 30 AMP RV plug.
It is obviously an extremely impressive and very capable little unit. I'll leave a link down in
the description. And I think I hear the inspector. Zack: haha
Cambry: Third times the charm. Here I come. Okay Zack: Welcome back. Things have changed.
Cambry: Yeah! I feel like this doesn't feel like a bunker anymore. It feels like Im in the back
of a like oil tanker converted into a motor home. Zack: All right. Not quite
the vibe we are going for. Cambry: Okay. Wow.
Zack. So yeah this is where the TV, TV is going to go over here. And then over
here is going to be like the sink and the fridge. And like the air system.
Cambry: Little Kitchenette. Zack: Yea. And then over here is
going to be the combustible toilet. Cambry: Mmm... is that ADA?
Zack: It will be, Yeah. Cambry: Is this the door?
Zack: Yea, it'll be a sliding door. Cambry: Wow! Okay.
Zack: Go ahead and go into the other rooms and flip the switches.
Cambry: Woah! What's this? Zack: That's an inground uh outlet.
So you can like plug stuff into it. Cambry: This is so legit now!
I can see.. see the future. Zack: Want to flip the switch?
Cambry: Okay... what fits in this space? Zack: Um these are going to be the bunk rooms.
Cambry: Oh okay. Did you try laying down flat to see if you'd fit?
Zack: Um.. it'll be cozy haha. So it's all run off of the batteries now so there's permanent
batteries run under the floor and everything. Cambry: That's cool.
Zack: We still have a lot of uh finish work to do so obviously the
walls aren't going to be this color. We need your input on like you know what to put over the
walls. Very much more built out than this. This is just temporary. Want to go into the last bedroom?
Cambry: Yes. Hey wait, wasn't there a bed in here? Zack: Yea, we took it out. We
didn't want it to start on fire. Cambry: OK good choice.
Zack: Yea. And right now it is 65 degrees Farenheit down here
which feels very good after having.. Cambry: So so much nicer down here.
Zack: Yea, did you feel the temperature? Cambry: Yea as I was dropping down
I was like, Oh thank goodness. Zack: Alright what suggestions do you have for us?
Cambry: We should get rid of that spider. Zack: Oh Hi.
Cambry: I'm just so excited. Like it really is coming to life. This feels.. feels less sketchy.
Zack: haha Cambry: The more it's filled out the more
legit it seems so.. it's exciting. Im.. yea. I love that it's already built out. Like
my brain is able to comprehend it better. Zack: So it looks like with all the lights
on we're pulling right around 200 Watts and we would have maybe 3 days worth of electricity
with just the light running. We're thinking about putting TVs up on the ceiling and then just
kind of like mimicking the weather outside. Cambry: That would be cool.
Zack: So if it's like raining Cambry: Harry Potter ceiling.
Zack: Exactly! Yea. Cambry: Love that.
Zack: If you want to grab one of your very own EcoFlow Delta Pro 3s I'll
leave a link for those down in the description. They have some massive deals going on right
now. And Cambry do you want to finish us off? Cambry: Thanks a ton for
watching. We'll see you around.
