ah the humble battery it makes everything from cruising down the
0:03
Boulevard in your car or cruising for a date on Tinder possible but have you
0:08
ever wondered how those little cylinders you can buy at gas stations and grocery
0:12
stores of those blocky things that you put in your laptop can store so much
0:16
energy well despite the massive diversity in battery types they all rely
0:20
on the same sort of chemical reaction to create energy which is actually very
0:24
similar to that Breaking Bad episode where Walter White builds his own
0:28
freaking battery out of coins and Weare what a badass a typical alkaline battery
0:33
you can buy at the store to put into your remote or whatever else contains an
0:36
anode on the negative end a cathode on the positive end an electrolyte paste
0:41
which contains ions which are electrically charged molecules different
0:45
materials make up the anode and cathode in a plain old alkaline battery the
0:49
anode is made of zinc like what you'd find in coins while the cathode is
0:54
comprised of maganese dioxide which may have actually been used as a Fire
0:59
Starter by by cave people but anyways
1:02
the ions in the electrolyte can combine with the zinc resulting in a reaction
1:07
that releases electrons when you close the circuit by putting the battery
1:11
inside of your favorite electronic device negatively charged electrons
1:15
leave the zinc anode go through your device providing electrical power and
1:20
flow back into the positively charged cathode these chemicals are readily
1:25
available and cheap making alkaline batteries readily available and
1:29
affordable able and convenient and etc etc but because chemical reactions used
1:34
up all the different substances inside of the battery and are hard to reverse
1:39
they're usually useless once they die in
1:42
fact trying to recharge a regular alkaline battery won't precisely result
1:47
in the opposite chemical reactions meaning you could wind up with dangerous
1:51
byproducts leaking everywhere so don't
1:54
do it fortunately many other types of batteries are rechargeable because they
1:59
use different chemicals that react in a way that make running the discharging
2:03
reaction in Reverse both easy and most
2:06
importantly safe today the most common
2:10
type of rechargeable batteries that you can buy in double A or AAA sizes is the
2:13
nickel metal hydride battery or NIMH not
2:17
only are n imh Batteries rechargeable but they also tend to last quite a bit
2:22
longer than their alkaline counterparts on one charge making them a good choice
2:26
for things like digital cameras that suck battery life fairly quickly however
2:32
they can be a bit tricky to recharge so make sure you're getting a quality
2:36
charger approved for the use of NIMH batteries don't try to use older
2:41
Chargers designed for largely obsolete nickel cadmium batteries which could
2:46
leave your NIMH batteries undercharged or even damaged not not good well okay
2:52
Luke that's all fine and dandy for my digital camera but what about the
2:55
batteries in my laptop or smartphone are those an imh actually those are usually
3:01
lithium ion batteries not n imh Batteries lithium ion batteries are the
3:06
kind of power source of choice for many rechargeable Electronics not only
3:09
because of their high energy density and
3:12
longer run times but they don't suffer from issues such as the memory effect
3:17
which can affect uh other kinds of batteries and cause them to lose
3:22
capacity if they aren't fully drained before being recharged since we're
3:26
always unplugging and replugging in our laptops tablets and phones lithium ion
3:31
batteries are a great choice currently
3:34
since they don't care how much juice they have inside themselves when you go
3:38
to plug them back in they will just charge all the way up some newer devices
3:43
have even taken lithium ion batteries a step farther with Lithium Polymer
3:47
designs that contain electrolyte gel making it possible to fit the battery
3:52
into a small flexible package ideal for thin higher performance devices like
3:58
high-end smartphones but even newer rechargeable batteries aren't perfect
4:02
over time all those charge and discharge Cycles will cause batteries to wear out
4:07
due to chemical reactions proceeding not quite perfectly and of course most of us
4:13
are still frustrated with our batteries dying after just a day's use or just a
4:17
few hours with something like a laptop so as we continually demand faster
4:22
mobile devices with longer battery life there are a number of experimental
4:25
battery technologies in the works that could one day make charging your phone
4:30
every night a thing of the past oh please make that happen these batteries
4:35
could be things such as ceramic cathodes or glass electrolytes and are not only
4:40
more durable but could last several times larger than current rechargeable
4:43
battery Tech due to higher energy densities Apple has been heavily rumored
4:48
to be looking at Ceramic batteries for some of its future products so in the
4:52
near future you might only have to remember to charge your iPhone once
4:57
every few days especially important if your usual activities consist of walking
5:01
around Las Vegas with like a selfie stick you know who hasn't used batteries
5:06
bears but these Bears can tunnel you into up to 20 different countries for
5:11
your internet so you can like browse as if you're from that country which is
5:15
pretty cool and you can use online services as if you're from that country
5:18
as well they have easy to ous apps for iOS Android PC and mac and a Chrome
5:22
extension just in case you you go that way just choose a country in the app
5:26
turn tunnel bear on and watch as your bear tunnels your internet connection
5:30
into your new location when you turn tunnel bear on two things happen your
5:35
connection gets encrypted with AES 256bit encryption and your public IP
5:39
address gets switched so you show up as if you're in that country to other
5:43
people tunnel bear lets you bypass all the annoying details that are typically
5:47
come with vpns for personal use there's no need to mess around with like Port
5:51
configurations DNS or any other router mumbo jumbo just let the tunnel bear
5:56
tunnel they also have a top rated privacy policy and do not log user
6:01
activity you can try out tunnel bear for free with 500 megabytes of data and no
6:05
credit card required but if you are interested upgrade to unlimited data you
6:09
can save 10% by going to Tunnel bear.com Linus so do that tunnel over to
6:14
TunnelBear do the thing and then you can
6:17
tunnel into other countries thank you guys for watching this video if you
6:21
liked it like it if you disliked it dislike it comment down below if there's
6:24
something else you'd like us to check out and don't forget to check out
6:27
channel superf fun where there's a video this week come on down click the screen
6:33
see what's happening I don't know no one knows do you know I don't know maybe you
6:37
know I don't know yet maybe you've already clicked there and figured it out and this video is still playing so you
6:42
can hear me talking and now you know whatever don't forget to subscribe to
