1
00:00:00,359 --> 00:00:05,839
ah the humble battery it makes everything from cruising down the

2
00:00:03,399 --> 00:00:10,519
Boulevard in your car or cruising for a date on Tinder possible but have you

3
00:00:08,200 --> 00:00:14,360
ever wondered how those little cylinders you can buy at gas stations and grocery

4
00:00:12,320 --> 00:00:18,279
stores of those blocky things that you put in your laptop can store so much

5
00:00:16,400 --> 00:00:23,000
energy well despite the massive diversity in battery types they all rely

6
00:00:20,359 --> 00:00:26,679
on the same sort of chemical reaction to create energy which is actually very

7
00:00:24,720 --> 00:00:30,679
similar to that Breaking Bad episode where Walter White builds his own

8
00:00:28,039 --> 00:00:34,520
freaking battery out of coins and Weare what a badass a typical alkaline battery

9
00:00:33,120 --> 00:00:39,040
you can buy at the store to put into your remote or whatever else contains an

10
00:00:36,719 --> 00:00:43,000
anode on the negative end a cathode on the positive end an electrolyte paste

11
00:00:41,480 --> 00:00:47,800
which contains ions which are electrically charged molecules different

12
00:00:45,440 --> 00:00:51,879
materials make up the anode and cathode in a plain old alkaline battery the

13
00:00:49,920 --> 00:00:57,440
anode is made of zinc like what you'd find in coins while the cathode is

14
00:00:54,520 --> 00:01:02,680
comprised of maganese dioxide which may have actually been used as a Fire

15
00:00:59,399 --> 00:01:04,960
Starter by by cave people but anyways

16
00:01:02,680 --> 00:01:09,960
the ions in the electrolyte can combine with the zinc resulting in a reaction

17
00:01:07,240 --> 00:01:13,360
that releases electrons when you close the circuit by putting the battery

18
00:01:11,680 --> 00:01:18,159
inside of your favorite electronic device negatively charged electrons

19
00:01:15,640 --> 00:01:23,439
leave the zinc anode go through your device providing electrical power and

20
00:01:20,840 --> 00:01:27,600
flow back into the positively charged cathode these chemicals are readily

21
00:01:25,600 --> 00:01:31,799
available and cheap making alkaline batteries readily available and

22
00:01:29,520 --> 00:01:36,920
affordable able and convenient and etc etc but because chemical reactions used

23
00:01:34,200 --> 00:01:42,920
up all the different substances inside of the battery and are hard to reverse

24
00:01:39,560 --> 00:01:44,799
they're usually useless once they die in

25
00:01:42,920 --> 00:01:49,360
fact trying to recharge a regular alkaline battery won't precisely result

26
00:01:47,520 --> 00:01:54,799
in the opposite chemical reactions meaning you could wind up with dangerous

27
00:01:51,799 --> 00:01:57,119
byproducts leaking everywhere so don't

28
00:01:54,799 --> 00:02:01,119
do it fortunately many other types of batteries are rechargeable because they

29
00:01:59,079 --> 00:02:06,759
use different chemicals that react in a way that make running the discharging

30
00:02:03,479 --> 00:02:10,000
reaction in Reverse both easy and most

31
00:02:06,759 --> 00:02:11,480
importantly safe today the most common

32
00:02:10,000 --> 00:02:17,360
type of rechargeable batteries that you can buy in double A or AAA sizes is the

33
00:02:13,840 --> 00:02:19,959
nickel metal hydride battery or NIMH not

34
00:02:17,360 --> 00:02:24,519
only are n imh Batteries rechargeable but they also tend to last quite a bit

35
00:02:22,319 --> 00:02:28,560
longer than their alkaline counterparts on one charge making them a good choice

36
00:02:26,920 --> 00:02:34,720
for things like digital cameras that suck battery life fairly quickly however

37
00:02:32,160 --> 00:02:39,720
they can be a bit tricky to recharge so make sure you're getting a quality

38
00:02:36,800 --> 00:02:44,159
charger approved for the use of NIMH batteries don't try to use older

39
00:02:41,519 --> 00:02:49,360
Chargers designed for largely obsolete nickel cadmium batteries which could

40
00:02:46,840 --> 00:02:54,200
leave your NIMH batteries undercharged or even damaged not not good well okay

41
00:02:52,360 --> 00:02:57,959
Luke that's all fine and dandy for my digital camera but what about the

42
00:02:55,599 --> 00:03:03,640
batteries in my laptop or smartphone are those an imh actually those are usually

43
00:03:01,400 --> 00:03:07,920
lithium ion batteries not n imh Batteries lithium ion batteries are the

44
00:03:06,000 --> 00:03:12,840
kind of power source of choice for many rechargeable Electronics not only

45
00:03:09,799 --> 00:03:15,159
because of their high energy density and

46
00:03:12,840 --> 00:03:20,519
longer run times but they don't suffer from issues such as the memory effect

47
00:03:17,959 --> 00:03:24,840
which can affect uh other kinds of batteries and cause them to lose

48
00:03:22,720 --> 00:03:29,239
capacity if they aren't fully drained before being recharged since we're

49
00:03:26,920 --> 00:03:34,920
always unplugging and replugging in our laptops tablets and phones lithium ion

50
00:03:31,840 --> 00:03:37,080
batteries are a great choice currently

51
00:03:34,920 --> 00:03:41,040
since they don't care how much juice they have inside themselves when you go

52
00:03:38,920 --> 00:03:45,599
to plug them back in they will just charge all the way up some newer devices

53
00:03:43,360 --> 00:03:50,760
have even taken lithium ion batteries a step farther with Lithium Polymer

54
00:03:47,920 --> 00:03:55,840
designs that contain electrolyte gel making it possible to fit the battery

55
00:03:52,879 --> 00:04:00,480
into a small flexible package ideal for thin higher performance devices like

56
00:03:58,319 --> 00:04:04,680
high-end smartphones but even newer rechargeable batteries aren't perfect

57
00:04:02,239 --> 00:04:10,200
over time all those charge and discharge Cycles will cause batteries to wear out

58
00:04:07,360 --> 00:04:14,720
due to chemical reactions proceeding not quite perfectly and of course most of us

59
00:04:13,000 --> 00:04:19,880
are still frustrated with our batteries dying after just a day's use or just a

60
00:04:17,359 --> 00:04:24,400
few hours with something like a laptop so as we continually demand faster

61
00:04:22,040 --> 00:04:28,160
mobile devices with longer battery life there are a number of experimental

62
00:04:25,880 --> 00:04:32,639
battery technologies in the works that could one day make charging your phone

63
00:04:30,320 --> 00:04:37,440
every night a thing of the past oh please make that happen these batteries

64
00:04:35,120 --> 00:04:41,880
could be things such as ceramic cathodes or glass electrolytes and are not only

65
00:04:40,039 --> 00:04:46,199
more durable but could last several times larger than current rechargeable

66
00:04:43,919 --> 00:04:50,960
battery Tech due to higher energy densities Apple has been heavily rumored

67
00:04:48,280 --> 00:04:55,080
to be looking at Ceramic batteries for some of its future products so in the

68
00:04:52,720 --> 00:04:59,880
near future you might only have to remember to charge your iPhone once

69
00:04:57,039 --> 00:05:03,840
every few days especially important if your usual activities consist of walking

70
00:05:01,800 --> 00:05:08,800
around Las Vegas with like a selfie stick you know who hasn't used batteries

71
00:05:06,720 --> 00:05:13,039
bears but these Bears can tunnel you into up to 20 different countries for

72
00:05:11,039 --> 00:05:16,600
your internet so you can like browse as if you're from that country which is

73
00:05:15,000 --> 00:05:20,560
pretty cool and you can use online services as if you're from that country

74
00:05:18,319 --> 00:05:24,720
as well they have easy to ous apps for iOS Android PC and mac and a Chrome

75
00:05:22,560 --> 00:05:28,479
extension just in case you you go that way just choose a country in the app

76
00:05:26,560 --> 00:05:32,800
turn tunnel bear on and watch as your bear tunnels your internet connection

77
00:05:30,560 --> 00:05:37,080
into your new location when you turn tunnel bear on two things happen your

78
00:05:35,319 --> 00:05:41,800
connection gets encrypted with AES 256bit encryption and your public IP

79
00:05:39,759 --> 00:05:45,680
address gets switched so you show up as if you're in that country to other

80
00:05:43,199 --> 00:05:50,000
people tunnel bear lets you bypass all the annoying details that are typically

81
00:05:47,639 --> 00:05:53,960
come with vpns for personal use there's no need to mess around with like Port

82
00:05:51,759 --> 00:05:58,600
configurations DNS or any other router mumbo jumbo just let the tunnel bear

83
00:05:56,120 --> 00:06:03,560
tunnel they also have a top rated privacy policy and do not log user

84
00:06:01,960 --> 00:06:06,599
activity you can try out tunnel bear for free with 500 megabytes of data and no

85
00:06:05,080 --> 00:06:12,000
credit card required but if you are interested upgrade to unlimited data you

86
00:06:09,360 --> 00:06:17,599
can save 10% by going to Tunnel bear.com Linus so do that tunnel over to

87
00:06:14,440 --> 00:06:20,240
TunnelBear do the thing and then you can

88
00:06:17,599 --> 00:06:23,000
tunnel into other countries thank you guys for watching this video if you
