Wilson Solar Grill - Heater
"David Wilson, a professor at MIT, came up with this baby barbecue requiring no use of firewood, coal, gas or electricity to operate. The futuristic-looking contraption serves both for grilling, cooking or heating food, and it also serves as a space heater, using only solar energy. Battery life of about 25 hours between recharging. This means that the energy stored in a single day in the sun can be used throughout the night and the next day. Perfect for outdoor cooking in large cities, but especially rural and remote communities."
"Wilson’s technology harnesses the sun and stores latent heat to allow cooking times for up to an amazing twenty five hours at temperatures above 450 degrees Fahrenheit. The technology uses a Fresnel lens to harness the sun’s energy to melt down a container of Lithium Nitrate. The Lithium Nitrate acts as a battery storing thermal energy for 25 hours at a time. The heat is then released as convection for outdoor cooking."
