ABOUT THE SPEAKER
William Kamkwamba - Inventor
To power his family's home, young William Kamkwamba built an electricity-producing windmill from spare parts and scrap -- starting him on a journey detailed in the book and film "The Boy Who Harnessed the Wind."

Why you should listen

William Kamkwamba, from Malawi, is a born inventor. When he was 14, he built an electricity-producing windmill from spare parts and scrap, working from rough plans he found in a library book called Using Energy and modifying them to fit his needs. The windmill he built powers four lights and two radios in his family home.

After reading about Kamkwamba on Mike McKay's blog Hactivate (which picked up the story from a local Malawi newspaper), TEDGlobal Conference Director Emeka Okafor spent several weeks tracking him down at his home in Masitala Village, Wimbe, and invited him to attend TEDGlobal on a fellowship. Onstage, Kamkwamba talked about his invention and shared his dreams: to build a larger windmill to help with irrigation for his entire village, and to go back to school.

Following Kamkwamba's moving talk, there was an outpouring of support for him and his promising work. Members of the TED community got together to help him improve his power system (by incorporating solar energy), and further his education through school and mentorships. Subsequent projects have included clean water, malaria prevention, solar power and lighting for the six homes in his family compound; a deep-water well with a solar-powered pump for clean water; and a drip irrigation system. Kamkwamba himself returned to school, and is now attending the African Leadership Academy, a new pan-African prep school outside Johannesburg, South Africa.

Kamkwamba's story is documented in his autobiography, The Boy Who Harnessed the Wind: Creating Currents of Electricity and Hope. A  documentary about Kamkwamba, called William and the Windmill, won the Documentary Feature Grand Jury award at SXSW in 2013 (watch a trailer ). You can support his work and other young inventors at MovingWindmills.org.

15
42000
4000
VK: Men maktabni tashlaganimdan keyin, kutubxonaga bordim
01:11
and I read a book that would -- "Using Energy,"
16
46000
4000
va "Energiyadan Foydalanish" deb nomlangan kitobni o'qidim.
01:15
and I get information about doing the mill.
17
50000
3000
Shu kitobdan tegirmon qurish to'g'risida ma'lumot oldim.
01:18
And I tried, and I made it.
18
53000
2000
Shunday qilib, harakat qilib tegirmon yasadim.
01:20
(Applause)

01:34
WK: Ah, no. I just --
21
69000
2000
VK: Ah, yo'q. Men shunchaki--
01:36
CA: What happened?
22
71000
2000
KA: Nima bo'ldi?
01:38
WK: In fact, a design of the windmill that was in the book,
23
73000
4000
VK: Aslida, kitobdagi shamol tegirmonining dizaynida
01:42
it has got four -- ah -- three blades,
24
77000
4000
to'rtta - ah - uchta diski bor,
01:46
and mine has got four blades.
25
81000
3000
men yasagan shamol tegirmonida esa to'rtta diski bor.
01:49

02:08
What materials did you use?
35
103000
2000
Qanday materiallardan foydalandingiz?
02:10

02:25
WK: When the wind blows, it rotates and generates.
40
120000
5000

03:13
WK: Yeah, I want to build another one --
56
168000
3000

03:16
to pump water and irrigation for crops.
57
171000
5000
suv tortib chiqarish va sug'orish uchun - hosillarni sug'orish uchun.
03:21
CA: So this one would have to be bigger?
58
176000
2000

61
180000
5000
VK: 20 vattdan ko'proq elektr ishlab chiqaradi deb o'ylayman.
03:31

62
186000
4000
KA: Shu butun qishloqqa sug'orish uchun yetarli bo'ladimi?
03:35
WK: Yeah.
