2016-07-21 19:01:34来源：网络

　　CA: What, to power -- for lighting and stuff?

　　0:48

　　WK: Yeah.

　　0:50

　　CA: So what did you do? How did you realize that?

　　0:53

　　WK: After I dropped out of school, I went to library, and I read a book that would -- "Using Energy,"and I get information about doing the mill. And I tried, and I made it.

　　1:06

　　(Applause)

　　1:16

　　CA: So you copied -- you exactly copied the design in the book.

　　1:20

　　WK: Ah, no. I just --

　　1:22

　　CA: What happened?

　　1:24

　　WK: In fact, a design of the windmill that was in the book, it has got four -- ah -- three blades, and mine has got four blades.

　　1:35

　　CA: The book had three, yours had four.

　　1:37

　　WK: Yeah.

　　1:38

　　CA: And you made it out of what?

　　1:40

　　WK: I made four blades, just because I want to increase power.

　　1:45

　　CA: OK.

　　1:46

　　WK: Yeah.

　　1:47

　　CA: You tested three, and found that four worked better?

　　1:49

　　WK: Yeah. I test.

　　1:51

　　CA: And what did you make the windmill out of? What materials did you use?

　　1:56

　　WK: I use a bicycle frame, and a pulley, and plastic pipe, what then pulls --

　　2:02

　　CA: Do we have a picture of that? Can we have the next slide?

　　2:05

　　WK: Yeah. The windmill.

　　2:07

　　CA: And so, and that windmill, what -- it worked?

　　2:11

　　WK: When the wind blows, it rotates and generates.

　　2:16

　　CA: How much electricity?

　　2:17

　　WK: 12 watts.

　　2:19

　　CA: And so, that lit a light for the house? How many lights?

　　2:24

　　WK: Four bulbs and two radios.

　　2:26

　　CA: Wow.

　　2:27

　　WK: Yeah.

　　2:28

　　(Applause) CA: Next slide -- so who's that?

　　2:40

　　WK: This is my parents, holding the radio.

　　2:43

　　CA: So what did they make of -- that you were 14, 15 at the time -- what did they make of this? They were impressed?

　　2:50

　　WK: Yeah.

　　2:51

　　CA: And so what's your -- what are you going to do with this?

　　2:53

　　WK: Um --

　　2:55

　　CA: What do you -- I mean -- do you want to build another one?

　　2:59

　　WK: Yeah, I want to build another one -- to pump water and irrigation for crops.

　　3:07

　　CA: So this one would have to be bigger?

　　3:09

　　WK: Yeah.

　　3:10

　　CA: How big?

　　3:11

　　WK: I think it will produce more than 20 the watts.

　　3:17

　　CA: So that would produce irrigation for the entire village?

　　3:21

　　WK: Yeah.

　　3:23

　　CA: Wow. And so you're talking to people here at TED to get people who might be able to help in some way to realize this dream?

　　3:32

　　WK: Yeah, if they can help me with materials, yeah.

　　3:36

　　CA: And as you think of your life going forward, you're 19 now, do you picture continuing with this dream of working in energy?

　　3:46

　　WK: Yeah. I'm still thinking to work on energy.

　　3:51

　　CA: Wow. William, it's a real honor to have you at the TED conference. Thank you so much for coming.

　　3:57

　　WK: Thank you.

　　3:59

　　(Applause)
