A Victoria teenager has won one of the top prizes in Google's annual global science fair.
Ann Makosinski's battery-free flashlight, which is powered by the heat of her hands, was chosen as the best project created by a student aged 15 or 16.
Makosinski said the idea came from an interest in harvesting humans' untapped thermal energy.
Her work was chosen from thousands of projects submitted by students in more than 120 countries.
The grand prize winner was 17-year-old Eric Chen for his project dubbed "the taming of the flu," which used computer modelling to identify influenza inhibitors that could be used for antiviral drugs.
