Student Invents Solar-Powered Fridge

Simply place perishable foods or temperature-sensitive medications in the solar refrigerator’s interior metal chamber and seal it. In-between the inner and outer chamber, organic material like sand, wool or soil is then saturated with water. As the sun warms the organic material, water evaporates, reducing the temperature of the inner chamber to a cool, 6 ºC [43 ºF] for days at a time!
After winning £5,000 from York Merchant Adventurers for her idea, Emily delayed going to college for a year to take her refrigerator to Africa for further development.
At 16 Emily won a regional Young Engineer for Britain Award for creating a toothpaste squeezer for people with arthritis, and the next year went on to win a Sustainable Design Award for a water-carrier made from wood and rubber tubing. In 2007 Emily was named the British Female Innovator of the Year, and last year was short-listed for Cosmopolitan’s 2008 Ultimate Women of the Year Competition.
