How many times have you tried to switch on a flashlight, only to find the batteries are dead? Well, here’s one that works simply with the heat of your hand. All you need is to be alive — and warm.
The Hollow Flashlight is the invention of 15-year-old Ann Makosinski of Victoria, Canada, whom we wrote about in July. Her flashlight is one of four winning creations in the annual Google Science Fair.
With more than a thousand submissions, the event highlights teen innovation around the world. The grand prize of a $50,000 scholarship went to San Diego’s Eric Chen for his use of computer modeling to discover new flu medicines.
Chen is only 17 and is already trying to save the world. He used a supercomputer and biological experimentation to find ways to speed up the discovery of influenza inhibitors ahead of future flu pandemics.
