A 15-year -old student who invented a flashlight getting power from the holder's body heat is going home today from California with a big prize and a chance to do research.
Ann was the only Canadian the four winners at Google's international science competition. The four winners were chosen from 15 final competitors from eight countries. The, competition attracted thousands of students in 120 countries.
Thousands of young from around the world took part in the competition. Winning the science and technology competition was a "surprise". Ann said, "I think it will have a great influence on my future.
Ann thanked her family for her interest in science and said that her first toy was a box of transistors (晶体管). Ann's prize $ 25,000 and a "once- a- lifetime experience" from Google for her Hollow Flashlight, which has no moving parts or batteries (电池).
The idea for the came from seeing unwanted batteries and her friend's experience. When Ann visited a friend in the Philippines, she saw the
friend couldn't study ，when it became dark because there was no electricity or light. She saw the need for a flashlight that has no batteries- Hollow Flashlight.
In her project, Ann wrote, "I made two flashlights that do not use any batteries or harmful materials. They do not create any noise and will always work. The flashlight needs at least a 5"C temperature difference between the holder's body and the environment around to produce light."
A video of Ann explaining how she invented the flashlight has been more than 1. 4 million times on the Internet.
Though Ann was successful, she has not made a decision about her career path. Ann hopes that she can find a way to join her love of film and science together.
