Solar cooking

Some areas are going to be easier to use but thermal energy is what is needed.

Wilson solar grill stores the sun's energy for fuel-free grilling every night

Sort of a back yard BBQ .

Grilled food is undeniably delicious, let it be burgers, chicken, corn on the cob, steak, or something more inventive. During warm weather, it's an enjoyable time to connect with family, neighbors, friends, and old acquaintances.

Unfortunately, our grills are harmful to the environment. Whether you use wood chips, charcoal, or propane, it releases emissions and creates poor air quality. Up until now, solar-powered cookers needed to the sun in order to function, which means that the environment suffers by night and evening barbecues, which, to be honest, is the prime time to have them.

This genius found the perfect solution for us to barbecue without ruining our environment.

Wilson Solar Cookers Without Fuel
MIT professor David Wilson developed a new solar technology that will bring a solar cooker that functions at night. This invention will significantly benefit developing nations who depend on wood for cooking.

Wilson's technology concept harnesses the sun and stores the latent heat for cooking for up to twenty-five hours at temperatures above 450 degrees Fahrenheit. The technology uses a Fresnel lens to hold the sun's energy to melt a container of Lithium Nitrate which acts as a thermal-storing battery for 25 hours at a time. Afterwards, the heat is released for our favorite way to cook outdoors.

"There are a lot of solar cookers out there," Wilson says, "but surprisingly not many using latent-heat storage as an attribute to cook the food." There have been solar cookers, grills, and ovens made before, but they all had to be used during the day to function.
