This solar powered grill will even let you cook at night

Are you a gas griller or a charcoal griller? How would you feel about switching to solar?

You've probably seen solar-powered grills in the past. Maybe you've even tried building your own. But those grills probably didn't let you cook at night.

This grill, on the other hand, uses the sun's rays to melt down a container of lithium nitrate that's housed inside the body of the grill. For the pyrotechnically inclined, lithium nitrate is the oxidizing agent used in the manufacture of most red-colored fireworks and flares. But you didn't hear that from me.

In any case, it just so happens that if you melt down all of the barbeque's lithium nitrate, it can store enough latent heat to cook for up to 25 hours straight, at temperatures upwards of 450 degrees Fahrenheit.

The technology was designed by MIT professor David Wilson, who first thought of the idea while spending time in Nigeria, where he observed a number of health and social problems tied to the practice of cooking with firewood. Wilson is now working with students at MIT to develop a distribution model that would put these grills at the disposal of communities in developing countries.
