In massachusetts, the army quartermaster corp shows a new solar furnace capable of generating heat close to that of a nuclear explosion. Exterior, in a field with sparse trees, three structures of some sort, one vaguely resembling a drive-in movie screen but at an angle. Two Caucasian men in uniform look up toward a structure. Flames shoot from a circular portion of some unknown, unique apparatus. Parts of this same apparatus - they seem to function like horizontal flaps across an air vent - move to a tilt so that they are angled downward, and the fire is extinguished. More shots of basically the same thing happening.
