The Solar Powered Cooker That Stores the Sun’s Energy for Fuel-Free Grilling Every Night

Barbeque is the most famous and favorite way of preparing meat in the world.

Grilled food is incredibly delicious and there are plenty of recipes that you can enjoy. Preparing barbeque is practically a must during the warm sunny days when you can gather your family and friends in your yard and enjoy the delicious food.

The only downside of it is that it is not environmental friendly and can be harmful. No matter what you use to flame up your grill, be it wood chips, charcoal, or propane, it releases emissions and creates poor air quality.

But, fear not BBQ lovers! Luckily, a genius found a way to keep the environment safe and your belly full!

Wilson Solar Cookers without Fuel

You can thank MIT professor David Wilson for this genius invention. He developed a new solar technology that will bring a solar cooker that functions at night! The most important thing is that it will significantly benefit developing nations who depend on wood for cooking.

The solar grill uses sun’s energy and stores the latent heat for cooking for up to twenty-five hours at temperatures above 450 degrees Fahrenheit. The grill 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.

The ability to use the grill at night is what makes it different than the rest. “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.”

The brilliant idea popped in Wilson’s head after visiting Nigeria where their standard cooking method uses wood which results with issues like, respiratory illnesses, deforestation, and women being vulnerable to rape while searching for the firewood.

The technology for a prototype solar grill is being developed by a group of MIT students. Derek Ham, Theodora Vardouli, and Eric Uva are conducting a study through the multi-disciplinary course “iTeams,” which is short for “Innovation Teams”, to assess the concept and to then potentially launch a business to manufacture and distribute the barbeque.

The main goal is to create a business model that will distribute the invention to the developing nations. The grill will be presented to the American market as well. The American version is potentially going to be a hybrid propane/solar model that will allow for flame cooking as thoroughly as thermal convection.
