Among them was 15-year-old Ann Makosinski from Victoria, who later that month made the final round, the only Canadian among 15 worldwide finalists.
Today the Canadian teenager won the top prize for a project creared by a student aged 15 or 16. Her project was The Hollow, a thermoelectric flashlight that operates solely from the heat of the human hand.
“Using four Peltier tiles and the temperature difference between the palm of the hand and ambient air, I designed a flashlight that provides bright light without batteries or moving parts,” she explains. “My design is ergonomic, thermodynamically efficient, and only needs a five degree temperature difference to work and produce up to 5.4 mW at 5 foot candles of brightness.”
Her two-minute YouTube video, which was published in April to little fanfare, now has nearly 1.5 million views.
