A uranium core? A miniature sun? Molten lava? None of the above I'm afraid. Like the blacksmiths of yesteryear, the Cook-Air uses bellows, or in this case a fan, to provide an ample source of oxygen to fuel the flames.
Instead of a bottle of propane or other combustible gases, the Cook-Air uses simple compressed wooden pucks (made from recycled scraps) that burn inside a chamber that's fed air through a ventilation system. In just five minutes the grill can reach searing temperatures of up to 1,100 °F and is claimed to have the equivalent of 65,000 BTUs of power. For reference, your average backyard gas BBQ has around 30,000.
To keep the $200 grill portable, the electric-powered fan can be powered by AC, a car adapter, or eight D-sized batteries, which is probably going to add a bit more heft. But, who cares if it cuts down on the time you have to wait for a perfectly cooked steak? [Cook-Air via Gizmag]
