Solar Grill Stores the Sun’s Energy
The new solar technology developed by MIT professor David Wilson could bring a nighttime solar-powered grill to the market very soon; an invention also of great benefit to those in developing nations who rely on wood to cook all their food.
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.
