Question

Teenage Inventors
It is never too early to start changing the world. These young people decided to do something to change the
world in a positive way.
Rifath Shaarook, from India, was the son of a local scientist. He was
interested in the skies from a young age. At just 18 years old, he and his
friends invented KalamSat, the world's lightest satellite. It weighed just 64
grams. It could be launched much more cheaply than regular satellites and was
used to do science tests in space.
Hannah Herbst, from the USA, invented the Beacon, an easily made
water turbine, at the age of 15. She had a pen friend in Ethiopia who didn't
have electricity in her house, so Hannah decided to make something to
help her. Hannah's invention could be used in the ocean or a big river to
make power for poor homes at a low cost.
Lalita Srisai, from India, built a water filter using old corn cobs. Many poor
people in India don't have clean water, but there is a lot of corn. Lalita began
testing her ideas when she was just 11 years old. When she was a child, a lot of
old corn was seen by the roadside, so she used it to make a special water filter. It
cleans about 80% of bad chemicals and bacteria from the water, and is very
cheap.
