elon musk recently tweeted that you
00:00:01
shouldn't drive your car with air
00:00:03
recirculation on which means it's
00:00:05
blowing air around and around and around
00:00:07
instead of taking air in from the
00:00:08
outside and that you should get a carbon
00:00:10
dioxide monitor to monitor the co2
00:00:13
levels in your car but also in your
00:00:14
house your office etc so what did i do i
00:00:17
got a co2 monitor
00:00:20
[Music]
00:00:30
hey y'all it's doctor know it all so yes
00:00:31
i got a co2 monitor because i figured
00:00:33
hey i'm going to test out the model y
00:00:35
and we're going to see what the co2
00:00:36
levels are with various things i'm also
00:00:38
going to test it in the house i've
00:00:40
checked a couple of places in the house
00:00:41
and actually down in the basement's a
00:00:43
little scary upstairs wasn't so bad but
00:00:46
i'm going to see how high it gets before
00:00:47
it stops because it keeps counting up
00:00:48
until it gets to a stopping place but
00:00:50
we're at 900 so we're just getting to
00:00:52
the yellow level here but anyway you can
00:00:54
see it's got co2 it's got temperature
00:00:56
and it's got relative humidity and it's
00:00:58
got an alarm that goes off if it gets
00:00:59
above 1500 parts per million so that's
00:01:02
actually super useful and you can keep
00:01:03
it around the house if you're interested
00:01:05
this particular model i'll leave a link
00:01:07
to that in the description it's on
00:01:08
amazon i just picked up a mid-range one
00:01:10
it was like 55 so i figured it looked
00:01:12
like it had a nice monitor because you
00:01:14
can see how it goes from green to yellow
00:01:16
and then to red if it gets bad over
00:01:17
there and we'll see that in just a
00:01:19
moment but anyway let's take a look at
00:01:21
the experiments outside inside and in
00:01:23
the car most particularly i took elon
00:01:26
musk's advice and purchased a
00:01:29
co2 and it does a whole bunch of other
00:01:30
things but anyway primarily it monitors
00:01:32
co2 and i'm actually running a
00:01:35
calibration step outside as you can see
00:01:38
so anyway it should be done in 18
00:01:40
seconds here it takes like 200 seconds
00:01:42
to calibrate and before i did the
00:01:44
calibration it was getting about 400
00:01:46
parts per million outdoors it said to do
00:01:48
the calibration outside by the way it is
00:01:50
ridiculously humid out here it's
00:01:52
something like 75 humidity out today
00:01:55
it's georgia in the summer time all
00:01:57
right so this thing should be just about
00:01:58
done and hopefully in a moment we will
00:02:01
see something that will appear oh there
00:02:03
we go
00:02:04
so i think it just takes a moment for it
00:02:06
to like do this because when i first
00:02:07
turned it on it said 500 parts per
00:02:09
million and then it changed but anyway
00:02:10
what i'm going to do here is i'm going
00:02:12
to go inside the house
00:02:14
so i think anything over like a thousand
00:02:16
parts per million is not particularly
00:02:18
good i like this one in particular
00:02:21
because it has like a green and then a
00:02:23
yellow and a red if it gets really bad
00:02:25
and so i'm going to test this out in the
00:02:26
house yeah you can see 73 relative
00:02:28
humidity it's ridiculous outside i'm
00:02:31
sweating sitting here in the shade uh
00:02:33
but anyway i think it's going to take a
00:02:34
moment for it to actually start to
00:02:35
register because i doubt it's 500 i
00:02:37
think that's just the default but the
00:02:39
most important thing so i'm going to
00:02:40
check the inside of the house in several
00:02:42
different rooms just to see but the most
00:02:45
important thing is i'm going to drive
00:02:47
over to the grocery store because i have
00:02:48
to go buy some groceries and i'm going
00:02:51
to turn the air recirculator on so
00:02:54
basically it's just blowing air from
00:02:56
inside out again and i'm going to check
00:02:59
and see what that looks like after you
00:03:01
know driving for like 10 or 15 minutes
00:03:03
i'm not going to the closest oh there we
00:03:05
go see it knocked it down to 410.
00:03:07
so yeah you can see it's 30 degrees
00:03:09
centigrade 76 relative humidity and 410
00:03:13
parts per million so
00:03:14
reasonable so it's all in the good you
00:03:16
can see it's in that little good thing
00:03:17
there but anyway what i'm going to do is
00:03:19
i'm going to try it with the with the
00:03:21
air being recirculated and see how bad
00:03:23
it gets with only one person in the car
00:03:25
my wife is out of town so can't use her
00:03:28
as a test guinea pig
00:03:30
but we'll see what happens in 15 minutes
00:03:32
and then if it gets up pretty high what
00:03:33
i'll do on the way back is i will turn
00:03:35
on the you know blowing the air in from
00:03:37
the outside as opposed to from the
00:03:39
inside and we will see if we have better
00:03:41
results all right wow 80 relative
00:03:44
humidity all right anyway so let's check
00:03:46
indoors next and see how that is all
00:03:48
right so now we're indoors and uh yeah
00:03:50
you can see it's going up rapidly here
00:03:53
i don't know why it still says it's 30
00:03:54
degrees centigrade i have it probably
00:03:56
takes a few minutes for the
00:03:58
thermometer to actually
00:03:59
you know achieve ambient temperature
00:04:01
with the rest of the space but you can
00:04:03
see that the relative humidity has gone
00:04:05
down to 64 which is still pretty high
00:04:08
and the co2 parts per million is uh
00:04:10
continuing to climb so it looks like it
00:04:13
takes maybe a minute or so for it to
00:04:15
kind of stabilize and give you um a
00:04:18
sense of this but this also just fyi you
00:04:21
can hang it on the wall
00:04:22
and it's got a usb charging port
00:04:25
um they shipped it with complete like
00:04:27
with the battery completely full which
00:04:28
was really nice i appreciate that
00:04:30
i always hate when the battery's like
00:04:31
mostly dead but my goodness it still
00:04:33
keeps climbing
00:04:34
i'm a little bit worried now because you
00:04:36
know i think over about 750 parts per
00:04:38
million would start to get a little iffy
00:04:40
indoors again it has been um
00:04:43
you know you can see i'm living here
00:04:45
right now both my son and my wife are
00:04:48
out of town so it's all me by myself so
00:04:50
actually it's probably reasonable but i
00:04:52
would imagine with more people in the
00:04:53
house it would be worse so it looks like
00:04:55
it's actually stabilized at 686 parts
00:04:57
per million so still as you can see in
00:05:00
the good range so that's good so next
00:05:02
we're going to try driving i'm going to
00:05:03
get in the car i was in there this
00:05:05
morning briefly but nobody's been in
00:05:08
there for hours so we'll take a look at
00:05:09
what the co2 level is immediately and
00:05:12
then over time as i drive it
00:05:14
all right so i let this thing sit for a
00:05:16
couple of minutes in the car without me
00:05:18
in the car so that's sort of our default
00:05:20
value of 567 which is still higher than
00:05:23
outdoors but anyway
00:05:25
we will see how that works anyway i'm
00:05:27
going to lean it back in that little
00:05:28
slot so it can stay there while i drive
00:05:30
and then i guess i'm going to have to
00:05:31
turn off auto mode so i can manually
00:05:33
specify
00:05:35
recirculation okay so i'm going to put
00:05:37
it on recirculation mode and uh i'll
00:05:40
turn off auto which i i always leave
00:05:43
auto on so anyway we'll see it looks
00:05:45
like it's already starting to climb so
00:05:48
what i'm going to do is drive like i
00:05:49
said it's about a 15 minute drive and we
00:05:52
will see what happens we will go to
00:05:53
kroger and i'll film this a little bit
00:05:56
as i go but again like i said i'm on my
00:05:58
own so mostly it's just the results it
00:06:00
doesn't really matter about the drive
00:06:02
but i will time the drive just to make
00:06:03
sure that i know exactly how long i was
00:06:04
in the car all right so just fyi i've
00:06:08
been in the car for about two minutes
00:06:10
right now and it's already up to 799
00:06:13
climbing to 800. again i've got the
00:06:15
recirculation on so it's recirculating
00:06:18
air but this is a little bit terrifying
00:06:20
that it's going up this quickly
00:06:22
um so anyway i haven't even i haven't
00:06:24
gotten out of our neighborhood yet so
00:06:25
it's already that high so we'll see how
00:06:27
it does it's supposed to be a 12 minute
00:06:29
drive so we will check back again when i
00:06:31
get to a stoplight
00:06:33
all right so uh gosh i guess it's been
00:06:35
about four to five minutes of driving
00:06:37
but uh you can see it's well over a
00:06:39
thousand already
00:06:40
and uh that's a little terrifying
00:06:43
actually so anything over a thousand is
00:06:45
supposed to make you kind of drowsy and
00:06:47
less than your optimal when you're
00:06:49
working so this is one of those things
00:06:51
where you can definitely check your
00:06:52
office or your home or something and see
00:06:54
what the what the ratings are around
00:06:56
there but as you can see it's climbing
00:06:57
very very quickly and i'm just one
00:06:59
person in the car this is not you know
00:07:01
this is not a group of people this is
00:07:03
just me all by myself and by the way
00:07:05
this particular monitor has a buzzer
00:07:07
that goes off if you get over 1500 parts
00:07:09
per million is kind of a warning sorry
00:07:11
as you can see better uh but anyway if
00:07:13
it if it gets to there i may have to
00:07:15
turn it off because it might be very
00:07:17
annoying but it looks like it's going to
00:07:18
get there really fast well before i
00:07:20
arrive at kroger anyway we'll check back
00:07:22
in a minute the light just changed all
00:07:23
right so we're now in about 10 minutes
00:07:25
sorry the bad reflection's here
00:07:28
there we go
00:07:29
but you can see that we're at um 1256
00:07:32
parts per million it's about two more
00:07:34
minutes to when i get to the store i may
00:07:35
hang out in the car for just a few
00:07:37
minutes to see if it gets to 1500
00:07:39
because that's the part where the
00:07:40
buzzer's supposed to go off but anyway
00:07:42
it it's taken just about 10 minutes for
00:07:44
it to get from what was that like 550 to
00:07:48
way more than double that so that's
00:07:50
pretty frightening and that's with the
00:07:51
air re-circular recirculation on again
00:07:53
just as a reminder well as you can see
00:07:55
we are approaching 1500 so oh
00:07:59
so we've officially gone into
00:08:01
dangerous territory yeah okay i'm not
00:08:04
gonna make you guys listen to that for
00:08:06
too long i'm not sure how to turn it off
00:08:08
maybe if i push the button up here
00:08:10
nope it's just gonna be so you can see
00:08:12
it's gotten up to 1640 i mean my
00:08:14
goodness that is terrifying so all right
00:08:17
i'm going to turn this off and we'll
00:08:19
reset here all right so as you can hear
00:08:21
auto is on now
00:08:22
it automatically kicked it back in again
00:08:24
we're at 5 16 in the car it was 750
00:08:27
inside the kroger so i guess not too
00:08:29
terrible but anyway so we are going to
00:08:31
see it should be another you know 12 or
00:08:33
so minutes to get back home again so
00:08:35
right now until 5 17
00:08:37
and let's see as you can see here auto
00:08:41
and i believe that would be oh actually
00:08:43
wait let me see if i can
00:08:45
uh
00:08:46
turn off okay
00:08:48
yeah i had turned it on and i guess it
00:08:50
had stayed on so anyway we're going i've
00:08:52
turned off the uh i don't know if you
00:08:54
can see that geez the reflections are
00:08:55
terrible anyway i turned off the um the
00:08:58
recirculation here so
00:09:00
now it's time to drive home or it's 6 25
00:09:03
so it is going up but you can also hear
00:09:05
the blower because it's you know very
00:09:07
hot outside
00:09:08
32 degrees outside
00:09:10
and i've got it set for 19 down here so
00:09:12
anyway hopefully this will not continue
00:09:15
to climb because my goodness that was
00:09:16
terrifying
00:09:18
all right well as you can tell even with
00:09:20
the air recirculation off we're still at
00:09:23
11 12 right now so
00:09:25
it's climbing it's definitely more slow
00:09:27
than it was before
00:09:28
uh the if it gets up to 1500 parts per
00:09:31
million i'm going to
00:09:33
do something where i
00:09:35
open up the windows to check on it
00:09:37
because i'm curious to see how that will
00:09:39
work but it has been climbing slower
00:09:41
than with the recirculation on but
00:09:43
definitely not what i would call
00:09:45
uh ideal at this point so anyway
00:09:48
interesting interesting it does seem to
00:09:50
nope it's still going up so yeah we'll
00:09:52
see we'll see what happens it'll be a
00:09:54
few more minutes before i get home
00:09:56
and back home i close the windows and
00:09:58
even with the air recirculation blowing
00:10:00
you can uh definitely tell that it's
00:10:02
starting to go back up again so
00:10:05
interesting it's basically if you close
00:10:07
the windows you're going to have higher
00:10:09
co2 levels that's that's pretty much the
00:10:11
fact
00:10:12
all right so as you saw the model y is
00:10:14
actually pretty hermetically sealed like
00:10:16
in here it seems like the basement is
00:10:18
worse than the upstairs probably because
00:10:19
it's much more sealed because it's a
00:10:21
half exposed basement so half of the
00:10:23
house like this side is completely
00:10:25
underground and only that side has a
00:10:27
couple of doors that lead outside so
00:10:29
probably we're talking about a lot more
00:10:31
co2 getting trapped in the basement the
00:10:33
upstairs has a dog door it has windows
00:10:35
everywhere it has doors that have you
00:10:37
know leaking stuff so it's leaking a lot
00:10:39
and i have some some plants up there so
00:10:41
one thing i might need to do is try to
00:10:42
find some like low-light plants and put
00:10:44
them down here to try to absorb a little
00:10:46
bit because 925 parts per million is not
00:10:49
unsafe but it's not fantastic so anyway
00:10:52
that's an interesting fact just to find
00:10:54
out but the more important part of this
00:10:56
is it was absolutely crazy with just one
00:10:59
person in the car that was just me in
00:11:00
the car with air recirculation on in
00:11:03
about 10 to 12 minutes i hit 1500 parts
00:11:06
per million and the alarm went off that
00:11:08
is pretty crazy that's far more co2 in
00:11:11
the air than i expected interestingly
00:11:13
enough i started having a headache and
00:11:15
feeling a little bit weird but i'm
00:11:17
pretty much positive that that was
00:11:19
because i was looking at this number
00:11:20
going up and freaking myself out because
00:11:22
you know clearly i've driven the car
00:11:24
around a lot of times without thinking
00:11:25
about it but anyway having recirculation
00:11:27
on was not great the interesting part
00:11:29
was even turning recirculation off so it
00:11:31
was pulling a lot of air in from the
00:11:33
outside it was having to do a lot of air
00:11:35
conditioning and blow a lot of air in
00:11:37
from the outside but it was still well
00:11:39
over 1300 parts per million before i
00:11:42
rolled the windows down when i rolled
00:11:44
the windows down it just took a minute
00:11:45
or two before it was at like outdoor
00:11:47
levels of like 440 450 parts per million
00:11:50
so it went down really fast but as i
00:11:53
said the big problems with that are
00:11:54
number one of course if it's hot or cold
00:11:56
you're going to get hot or cold because
00:11:58
you're going to be exposed to the
00:11:59
atmosphere it did feel kind of nice to
00:12:01
have the air blowing around i have to
00:12:03
say but the bigger part if you're
00:12:04
driving long distances is that your
00:12:07
vehicle's range is going to go way down
00:12:09
obviously if you're just driving around
00:12:11
town it doesn't matter if you lose a few
00:12:13
miles because the windows are open and
00:12:15
you're creating turbulence but if you're
00:12:16
driving a long distance on the highway
00:12:18
especially or something you're going to
00:12:19
lose a lot of range if you keep the
00:12:21
windows down but on the other hand if
00:12:23
you're doing like long commutes or if
00:12:25
you're doing longish road trips and you
00:12:27
start getting tired i actually started
00:12:29
to realize i was like gosh no wonder you
00:12:31
know i go to drive to see my parents and
00:12:33
i get an hour into the drive and i'm
00:12:34
just completely exhausted and a lot of
00:12:36
that might not have to do with the fact
00:12:38
that i'm just tired or something it
00:12:40
might literally be the amount of co2 in
00:12:42
the vehicle and just as a quick reminder
00:12:44
if you're confused about this this is
00:12:45
not carbon monoxide carbon monoxide will
00:12:48
actually bind to your red blood cells
00:12:49
and can actually kill you co2 i guess it
00:12:52
could kill you if it was all co2 in the
00:12:54
atmosphere but it's not going to kill
00:12:55
you it's just going to make you less
00:12:57
than you know ideal less than optimal
00:12:59
you won't be you know be able to focus
00:13:01
as well as you should be able to you'll
00:13:03
be very sleepy things like that and of
00:13:05
course also it goes away immediately
00:13:06
because it's just expelled in your
00:13:07
breath that's what we're doing we're
00:13:08
giant co2 machines we take in oxygen and
00:13:11
we produce co2 fortunately there's a
00:13:13
bunch of plants outside that take in co2
00:13:16
and produce oxygen so it's all a nice
00:13:18
balance that works out but anyway so
00:13:20
it's not something that's unsafe in the
00:13:21
sense that it has long-term effects but
00:13:24
if co2 is in the air it's going to make
00:13:26
you sleepy it could give you a headache
00:13:28
there could be other things that go
00:13:29
along with that so having it lower is
00:13:32
really good so if you're on a longer
00:13:34
trip or something and you start getting
00:13:35
sleepy my recommendation from looking at
00:13:37
this is immediately roll the windows
00:13:39
down blast some fresh air in there for
00:13:41
four or five minutes and you should get
00:13:43
refreshed and feel a whole bunch better
00:13:45
and of course as elon said you shouldn't
00:13:47
turn recirculation on in the vehicle
00:13:49
because he said it doesn't really save
00:13:51
that much on energy efficiency but it's
00:13:54
really bad for you in terms of co2
00:13:56
levels and stuff it looks like the
00:13:57
automatic systems pretty much turn the
00:14:00
recirculation off so it's blowing fresh
00:14:02
air in so that's a good thing because i
00:14:04
pretty much always have it on auto and
00:14:05
the last thing i learned is not really a
00:14:07
revelation about me because i already
00:14:08
knew this but now i'm going to be taking
00:14:10
this thing everywhere i took it into the
00:14:12
grocery store i was measuring the co2 in
00:14:14
there i'm going to take it to my office
00:14:15
i'm going to take it to every single
00:14:16
room in the house you can see it has
00:14:18
actually stabilized at 900 901 so it's
00:14:21
actually less than a thousand down here
00:14:22
but much much higher than upstairs so
00:14:24
this is interesting i'll have to take
00:14:26
some steps to mitigate that kind of
00:14:27
thing but i think this is fascinating to
00:14:30
get some actual data and look around i'm
00:14:32
gonna put this in the car and drive
00:14:33
around some more and get some more data
00:14:35
you know maybe because the humidity is
00:14:37
so ridiculously high right now it's
00:14:39
causing the co2 levels to be higher and
00:14:42
so maybe if it was a little bit nicer
00:14:44
outside and not so humid it would be
00:14:45
better so i'll test this out some more
00:14:47
but i thought it was certainly valid to
00:14:49
check this out and to see how much co2
00:14:52
is actually in a car and you can see
00:14:53
that a car is the absolute worst place
00:14:55
it's a very confined space very very
00:14:57
well sealed and you've got a lot of
00:14:59
people just producing co2 constantly so
00:15:01
maybe we should get some like house
00:15:03
plants or car plants and stick them in
00:15:04
the car
00:15:06
little plants to produce a little bit of
00:15:07
oxygen for us to make life better but
00:15:09
anyway in the meantime definitely turn
00:15:11
recirculation off and if you start
00:15:12
getting sleepy in the car i highly
00:15:14
recommend rolling the windows down for
00:15:15
four or five minutes because that did
00:15:17
the trick no problem at all all right i
00:15:19
