1
00:00:00,982 --> 00:00:03,756
This is where I live. I live in Kenya,

2
00:00:03,756 --> 00:00:06,823
at the south parts of the Nairobi National Park.

3
00:00:06,823 --> 00:00:08,811
Those are my dad's cows at the back,

4
00:00:08,811 --> 00:00:10,791
and behind the cows,

5
00:00:10,791 --> 00:00:13,095
that's the Nairobi National Park.

6
00:00:13,095 --> 00:00:16,600
Nairobi National Park is not fenced in the south widely,

7
00:00:16,600 --> 00:00:20,062
which means wild animals like zebras

8
00:00:20,062 --> 00:00:23,983
migrate out of the park freely.

9
00:00:23,983 --> 00:00:27,996
So predators like lions follow them,

10
00:00:27,996 --> 00:00:30,791
and this is what they do.

11
00:00:30,791 --> 00:00:33,792
They kill our livestock.

12
00:00:33,792 --> 00:00:36,239
This is one of the cows which was killed at night,

13
00:00:36,239 --> 00:00:40,279
and I just woke up in the morning and I found it dead,

14
00:00:40,279 --> 00:00:42,705
and I felt so bad,

15
00:00:42,705 --> 00:00:47,192
because it was the only bull we had.

16
00:00:47,192 --> 00:00:49,979
My community, the Maasai, we believe that

17
00:00:49,979 --> 00:00:56,036
we came from heaven with all our animals and all the land

18
00:00:56,036 --> 00:00:59,811
for herding them, and that's why we value them so much.

19
00:00:59,811 --> 00:01:03,570
So I grew up hating lions so much.

20
00:01:03,570 --> 00:01:06,623
The morans are the warriors

21
00:01:06,623 --> 00:01:09,940
who protect our community and the livestock,

22
00:01:09,940 --> 00:01:13,019
and they're also upset about this problem.

23
00:01:13,019 --> 00:01:16,024
So they kill the lions.

24
00:01:16,024 --> 00:01:19,938
It's one of the six lions which were killed in Nairobi.

25
00:01:19,938 --> 00:01:24,477
And I think this is why the Nairobi National Park lions are few.

26
00:01:24,477 --> 00:01:29,438
So a boy, from six to nine years old, in my community

27
00:01:29,438 --> 00:01:32,312
is responsible for his dad's cows,

28
00:01:32,312 --> 00:01:35,442
and that's the same thing which happened to me.

29
00:01:35,442 --> 00:01:38,857
So I had to find a way of solving this problem.

30
00:01:38,857 --> 00:01:43,671
And the first idea I got was to use fire,

31
00:01:43,671 --> 00:01:47,464
because I thought lions were scared of fire.

32
00:01:47,464 --> 00:01:52,183
But I came to realize that that didn't really help,

33
00:01:52,183 --> 00:01:54,792
because it was even helping the lions

34
00:01:54,792 --> 00:01:58,303
to see through the cowshed.

35
00:01:58,303 --> 00:02:01,632
So I didn't give up. I continued.

36
00:02:01,632 --> 00:02:04,272
And a second idea I got was

37
00:02:04,272 --> 00:02:06,339
to use a scarecrow.

38
00:02:06,339 --> 00:02:07,953
I was trying to trick the lions

39
00:02:07,953 --> 00:02:10,860
[into thinking] that I was standing near the cowshed.

40
00:02:10,860 --> 00:02:14,936
But lions are very clever. (Laughter)

41
00:02:14,936 --> 00:02:19,382
They will come the first day and they see the scarecrow, and they go back,

42
00:02:19,382 --> 00:02:22,656
but the second day, they'll come and they say,

43
00:02:22,656 --> 00:02:25,766
this thing is not moving here, it's always here. (Laughter)

44
00:02:25,766 --> 00:02:29,003
So he jumps in and kills the animals.

45
00:02:29,003 --> 00:02:32,956
So one night, I was walking around the cowshed with a torch,

46
00:02:32,956 --> 00:02:36,799
and that day, the lions didn't come.

47
00:02:36,799 --> 00:02:41,357
And I discovered that lions are afraid of a moving light.

48
00:02:41,357 --> 00:02:43,930
So I had an idea.

49
00:02:43,930 --> 00:02:46,240
Since I was a small boy,

50
00:02:46,240 --> 00:02:49,498
I used to work in my room for the whole day,

51
00:02:49,498 --> 00:02:52,604
and I even took apart my mom's new radio,

52
00:02:52,604 --> 00:02:54,422
and that day she almost killed me,

53
00:02:54,422 --> 00:03:00,676
but I learned a lot about electronics. (Laughter)

54
00:03:00,676 --> 00:03:04,036
So I got an old car battery,

55
00:03:04,036 --> 00:03:07,826
an indicator box. It's a small device found in a motorcycle,

56
00:03:07,826 --> 00:03:12,877
and it helps motorists when they want to turn right or left. It blinks.

57
00:03:12,877 --> 00:03:17,431
And I got a switch where I can switch on the lights, on and off.

58
00:03:17,431 --> 00:03:22,259
And that's a small torch from a broken flashlight.

59
00:03:22,259 --> 00:03:25,140
So I set up everything.

60
00:03:25,140 --> 00:03:28,364
As you can see, the solar panel charges the battery,

61
00:03:28,364 --> 00:03:30,485
and the battery supplies the power

62
00:03:30,485 --> 00:03:33,540
to the small indicator box. I call it a transformer.

63
00:03:33,540 --> 00:03:38,261
And the indicator box makes the lights flash.

64
00:03:38,261 --> 00:03:42,012
As you can see, the bulbs face outside,

65
00:03:42,012 --> 00:03:44,500
because that's where the lions come from.

66
00:03:44,500 --> 00:03:48,564
And that's how it looks to lions when they come at night.

67
00:03:48,564 --> 00:03:51,292
The lights flash and trick

68
00:03:51,292 --> 00:03:53,234
the lions into thinking I was walking around the cowshed,

69
00:03:53,234 --> 00:03:55,160
but I was sleeping in my bed.

70
00:03:55,160 --> 00:03:57,900
(Laughter)

71
00:03:57,900 --> 00:03:59,569
(Applause)

72
00:03:59,569 --> 00:04:05,164
Thanks.

73
00:04:05,164 --> 00:04:09,440
So I set it up in my home two years ago,

74
00:04:09,440 --> 00:04:12,760
and since then, we have never experienced any problem with lions.

75
00:04:12,760 --> 00:04:16,772
And my neighboring homes heard about this idea.

76
00:04:16,772 --> 00:04:19,236
One of them was this grandmother.

77
00:04:19,236 --> 00:04:23,512
She had a lot of her animals being killed by lions,

78
00:04:23,512 --> 00:04:25,646
and she asked me if I could put the lights for her.

79
00:04:25,646 --> 00:04:26,924
And I said, "Yes."

80
00:04:26,924 --> 00:04:31,524
So I put the lights. You can see at the back, those are the lion lights.

81
00:04:31,524 --> 00:04:34,940
Since now, I've set up seven homes around my community,

82
00:04:34,940 --> 00:04:37,165
and they're really working.

83
00:04:37,165 --> 00:04:42,345
And my idea is also being used now all over Kenya

84
00:04:42,345 --> 00:04:47,458
for scaring other predators like hyenas, leopards,

85
00:04:47,458 --> 00:04:49,693
and it's also being used

86
00:04:49,693 --> 00:04:53,738
to scare elephants away from people's farms.

87
00:04:53,738 --> 00:04:56,778
Because of this invention, I was lucky to get a scholarship

88
00:04:56,778 --> 00:04:59,428
in one of the best schools in Kenya,

89
00:04:59,428 --> 00:05:01,335
Brookhouse International School,

90
00:05:01,335 --> 00:05:04,262
and I'm really excited about this.

91
00:05:04,262 --> 00:05:08,112
My new school now is coming in and helping

92
00:05:08,112 --> 00:05:12,644
by fundraising and creating an awareness.

93
00:05:12,644 --> 00:05:17,927
I even took my friends back to my community,

94
00:05:17,927 --> 00:05:21,124
and we're installing the lights to the homes

95
00:05:21,124 --> 00:05:25,773
which don't have [any], and I'm teaching them how to put them.

96
00:05:25,773 --> 00:05:29,670
So one year ago, I was just a boy in the savanna grassland

97
00:05:29,670 --> 00:05:31,344
herding my father's cows,

98
00:05:31,344 --> 00:05:34,298
and I used to see planes flying over,

99
00:05:34,298 --> 00:05:38,509
and I told myself that one day, I'll be there inside.

100
00:05:38,509 --> 00:05:41,597
And here I am today.

101
00:05:41,597 --> 00:05:47,533
I got a chance to come by plane for my first time for TED.

102
00:05:47,533 --> 00:05:52,969
So my big dream is to become an aircraft engineer and pilot when I grow up.

103
00:05:52,969 --> 00:05:56,663
I used to hate lions, but now because my invention

104
00:05:56,663 --> 00:05:59,981
is saving my father's cows and the lions,

105
00:05:59,981 --> 00:06:03,681
we are able to stay with the lions without any conflict.

106
00:06:03,681 --> 00:06:06,901
Ashê olên. It means in my language, thank you very much.

107
00:06:06,901 --> 00:06:17,801
(Applause)

108
00:06:21,381 --> 00:06:23,682
Chris Anderson: You have no idea how exciting it is

109
00:06:23,682 --> 00:06:25,793
to hear a story like yours.

110
00:06:25,793 --> 00:06:27,829
So you got this scholarship.Richard Turere: Yep.

111
00:06:27,829 --> 00:06:30,406
CA: You're working on other electrical inventions.

112
00:06:30,406 --> 00:06:32,264
What's the next one on your list?

113
00:06:32,264 --> 00:06:34,938
RT: My next invention is,

114
00:06:34,938 --> 00:06:37,520
I want to make an electric fence.CA: Electric fence?

115
00:06:37,520 --> 00:06:39,681
RT: But I know electric fences are already invented,

116
00:06:39,681 --> 00:06:41,918
but I want to make mine.

117
00:06:41,918 --> 00:06:44,009
(Laughter)

118
00:06:44,009 --> 00:06:47,179
CA: You already tried it once, right, and you --RT: I tried it before,

119
00:06:47,179 --> 00:06:53,936
but I stopped because it gave me a shock. (Laughter)

120
00:06:53,936 --> 00:06:57,262
CA: In the trenches. Richard Turere, you are something else.

121
00:06:57,262 --> 00:07:00,230
We're going to cheer you on every step of the way, my friend.

122
00:07:00,230 --> 00:07:03,787
Thank you so much.RT: Thank you. (Applause)
