    accept I feel very happy to be at the

    first year of secondary
  • 00:02:32
    school so I was determined to do
  • 00:02:36
    anything possible to receive education
  • 00:02:39
    so I went to a library I read books
  • 00:02:42
    science books especially physics I
  • 00:02:45
    couldn't read English that well I used
  • 00:02:47
    diagrams and pictures to learn the words
  • 00:02:51
    around
  • 00:02:54
    them another book put that knowledge in
  • 00:02:57
    my
  • 00:02:58
    hands it say said windmill could pump
  • 00:03:02
    water and generate
  • 00:03:05
    electricity pump water meant irrigation
  • 00:03:08
    a defense against hunger which we
  • 00:03:11
    experiencing by that
  • 00:03:13
    time so I decid I'll build one wind for
  • 00:03:17
    myself but I didn't have materials to
  • 00:03:20
    use so I went to a scrapyard where I
  • 00:03:23
    found my
  • 00:03:25
    materials many people including my
  • 00:03:29
    mother
  • 00:03:30
    said I was
  • 00:03:33
    crazy I found a tractor fan
  • 00:03:36
    sha PVC pipes using a bicycle frame and
  • 00:03:42
    old bicycle Dynamo I built my
  • 00:03:46
    machine it was one light at first and
  • 00:03:51
    then four
  • 00:03:53
    lights with
