I had an idea to build an air water generation system A system that will capture the water out
of the humidity in the air now I'm going to do it with just stuff I lay around my house
this old AC unit that I don't use anymore and the swamp cooler from a previous build oh and
by the way I'm gonna make it all powered off of this battery and solar panels so how much
water can we actually produce how does it work let's no doubt a little bit about the
science and figure out if we can't build our own because these things are really expensive
let's see if we can put this out together I'm Ricky and it's Two Bit da Vinci
huge thanks to our friends over at EcoFlow for sending over this the Delta 2 Max this little
battery is going to power everything that you see here off of solar power we'll talk more about this
amazing little thing in just a second but let's start with some of the design considerations first
of all this this old portable air conditioner now if you have a portable air conditioner
you need to check if it has one hose out or two if it has one hose out you probably shouldn't
really use it it doesn't really do very much it's blowing air out of your house which means you
have a low pressure Zone and you're just going to have air seeping right back in from all the
little cracks and doorways and stuff so these things aren't really all that good that's why
we stopped using it but it does have everything that we need to make cold air the fundamental
principles are that we want to make the air hit that dew point and condense out we want the water
to condense out of the air and then over here we have a swamp cooler that has all of these
pleats that should capture that water and run around basically we're running this in Reverse
normally you put water underneath it pumps the water over the fins and evaporates out and blows
cold air into your house we want to go the other way around and see if it'll work take in cool
there see if you can hit those pleats and collect down below how well this is going to perform we
shall see but first up let's deconstruct this because as I mentioned we have a fan down here
this pen right here blows air up and over these two Heat exchangers this is the hot side that is
the coal side what we want to do is we want to make it so that this fan is just blowing
over the hot side and we need to take this off and figure out how hard this is going to be to
take it off and have this one be blown from the fan over on the swamp cooler but first a little
bit of deconstruction all right so the good news is uh we've got it off here now here's how this
works that fan I mentioned this scroll style fan is just blowing air up but we're going to reduct
it so that way this fan is only blowing air over the hot coil all right so we pulled the wire out
we can check the temperature of the cold side and kind of extra slack and we've removed all
of that now we're going to put it back together because we don't have to get back into this
next up we need to build a bracket so we can separate this a little bit more so we have
a lot of airflow and then close off this side for the hot side got our piece of wood cut and
this is going to block this off so that way this band is the only blowing in One Direction [Music]
all right we've got that all sealed up just a little pressure check and just make sure
everything is still working here's our old hedge unit I just have it sitting out here
power is on we'll put it on Cooling lower the temperature sufficiently
I'm just looking for any leakage that looks pretty good so now this fan hot air only we now
have to deal with this side I'm gonna turn it off because this isn't getting any cooling so this is
going to get cold and kind of saturated so I'll turn it off now that this is all working maybe
I'll tape this down what do you think that's the control system right here now we'll uh
we'll put these legs on this side to hold the swap cooler up nothing too fancy all right here we go
level iPhone level altitudestore.com I want to store one when are you going to build a new store
[Music]
okay now we have some trapezoids to cut out we're
gonna use this foam board to make the Shroud for our system [Music]
all right so on the other side we have the foam board but on this for a window we've got some
plexiglass so we can look in and see how much water is being captured and we'll put a foam
on the outside we're not looking in but while the guys cut that out let's take a minute and
talk about the battery by the way there are some amazing Amazon Prime Day deals going on
right now with ecoflow's entire lineup so we'll keep the links up to date in the description but
definitely check it out for some of the best deals on ecoflow's entire lineup of amazing
batteries links in the description all right we're almost done we're just wrapping this up
and then we're going to be able to do a little pressure test to make sure all the air
doesn't seep from anywhere but right through the heat exchanger the radiator all right so if you
look over here we're pretty much done we got the plexiglass up all the Air Force through here goes
in hits that match and the idea is that the air in here would be below the dew point in theory and
will condense out now how we're going to power this whole thing part of what made me really
excited about this project is that you could run one of these from anywhere if you have four solar
panels which we do and we've run wires down we're going to plug this into the back of the ecoflow
the ecoflow has two inputs for solar for a total of a thousand Watts let's plug that in now this
is important because otherwise you only can run it for a couple of hours and then that's not very
interesting but with this you could run it every day and how much let's find out I'm curious myself
all right we've got the solar plugged in ports are back here speaking of why don't we just show
off some of the ports in the back all right we have six AC ports you can turn the AC on and off
down here you have your 12 volt stuff cigarette lighter and all of that solar inputs and this is
how you would charge it from the wall so normally if you were to do like a camping trip not have
solar charge it here pull it off and you're on your way while we're back here we're going to
plug in the AC and our fan and we'll go through one by one and see how much power they're using
Stacy here's the fan all right and for that click as well all right that's all we're gonna do back
here let's put this back around so we can see the front screen so we're at 93 percent and right now
our input is 734 Watts now this is 4 30 in the afternoon the sun is already way over in the sky
we did some testing earlier on we were getting the full thousand Watts out of this earlier but
we're not going to get that this is going to start dwindling but we are producing solar there it is
right there now should we fire this thing up yeah let's do this all right we'll start with the AC
we have our beautiful control panel turn that on so the temperature really low
okay and we're on cool mode that is the fan running
and the oh the compressor is already on too So currently it's pulling 1200 watts
let's give that a second normally they'll kind of level out a bit
this probably a good point to talk about the capacity and what this battery can do this is
pretty amazing I could actually power two air conditioners off of one of these the maximum
output is 2400 Watts which is pretty amazing more than two of those in terms of storage capacity
this is two kilowatt hours so right now running this I could run it without solar for about two
hours but with solar coming in I'm actually only using about 300 watts in total I think that power
will settle around a thousand because remember now this fan used to blow over both but we've taped
this off so this is just blowing the hot air this is actually producing ice because of how cold this
is getting so we need to turn this fan on to keep the air going over that coil too there we go so
this is high speed why don't we set it to oh that is freezing freezing so we have two components you
can already see the water is dripping down from that really cool coil first of all this system
now is way more efficient because we have this fan moving all that hot air on that side meaning that
there's more heat being exchanged and on this side we have a whole second fan so we've doubled in
essence the amount of air flowing through it you don't just kind of see the water the main water
collection is going to be the uh the radiator up here and the reason is it's just freezing freezing
cold so this is our primary water we're going to be collecting but we're going to also be getting
some Dew on these grills these vents and we'll take a look at that so with both of those on we're
pulling 1400 we still have a thousand Watts more we can pull from this thing that's pretty amazing
and we have the solar coming in so tomorrow what I want to do when we get full daylight we'll charge
this up and then we'll see how long we can run all of this with the solar coming into it
all right moment of truth I'm not gonna lie we didn't really plan how to get water out
of this very well but here we go this is four hours okay there's two liters
we still have a little bit more
so almost four liters in four hours all off of this and solar we were not even using our own
energy by the way there's a smartphone app open it up and setup was incredibly easy because we
already have other Eco flip products it just told me hey new product detected I hit OK and
it added it right away it was really cool so here it is right here and as you can see here
we're producing almost 900 from solar it's 10 30 in the morning that will be a thousand fully maxed
out probably around noon and we're using 1.49 about 1.5 kilowatts now without the solar input
This would run for about an hour and 20 minutes right but with that solar input we can run this
pretty much for about four hours and collect that much water pretty amazing also it's staying pretty
cool definitely quieter than the compressor and everything else and it's just been bulletproof
it turns right on and it's powering all of that without any issue and what's really cool in the
app as well I can turn on my AC or turn it off for example right from the app my 12 volt DC
and the USB ports up front that these little buttons here you can trigger them all in the
application so let's really quickly talk about what we've accomplished here the weather right
now in San Diego is 71 degrees an amazing temperature for this time in the summer time
and the relative humidity is 69 what that means is 69 of the water that the air could
hold is actually in the air now the dew point is 60 degrees that means that if we can get the
temperature below 60 degrees there will be more than 100 humidity which means the water cannot
stay in the air any longer and it'll condense out and that's what we've accomplished with this heat
pump because this side is colder than 60 degrees as you can tell here all this water trickling down
look at all that so that's kind of the science behind this and
um I have all kinds of ideas for new ways to optimize it so first of all this whole swamp
cooler thing we put up because we were thinking well if the air in there is really cold we might
be able to capture more water out of it before it exits the system but from what I'm seeing
there is some there is some moisture in these channels but it's not a whole lot
so what I would do in the future maybe is redesign this and make the air blow this way over the cold
coils make the cold coils and the hot coils kind of like that and have that cold air go
through the hot coils to better cool off the hot side and have better efficiency and then collect
all the water and maybe add some desiccants or other things to really absorb that water
but this might be an ongoing Series where we try to maximize this and try to make more water with
less energy and see how much we can learn but that is a really awesome little one-day project and I'm
Blown Away by the results I can't believe we're producing water out of the air but that's not how
you're going to use this you're going to use it as a portable power station now you can probably
imagine we love ecoflow we have the Delta II which is a smaller one this is one kilowatt
hour and 1200 watts output the Big Brother Delta Max has two code hours and 2400 watts of output
and then we also have Delta Pros in the office those are three and a half kilowatt hours and
they can take in 1500 watts of solar input that means that with two more panels we could have
powered this thing all day producing water from the sun which is absolutely amazing but these
are kind of the lineup and there's quite a few options these both can take in an extra battery
so if you wanted to add on capacity you can just add them on later down the road and there's kind
of a product for every use case they have a really wide variety of products including generators so
the event of cloudy days and long power outages you can still produce electricity from gasoline
or natural gas and this one the Delta II is ultra portable but the Delta II Max I think is one I
would have most of the time because it can just do so much and it's still pretty portable so can
you make a water from Air Generation system and power it with a Delta II Max absolutely and pretty
easily if we had a smaller heat pump system with that thousand watts of solar input we could have
ran it all day but pretty impressive stuff but odds are you're gonna use it for a couple of other
things home backup power perhaps you could run a full refrigerator in your house for 14 hours with
one of these things or a TV for 15. I can power this laptop for like an entire weekend pretty
much plus with lithium iron phosphate batteries this will last well over 10 years and has some of
the best recharging times in the business whether it's on the wall or from solar and with that app
you can manage it all turn things on and off all remotely so that's a quick look at the Delta II
Max and just how much we were able to do with it so by the way don't forget to subscribe and join
us because we think we could do even better and build the system even more optimized to collect
more water in a future video so don't miss that and until then you gotta check out this video next
