Burning glass. A burning glass or burning lens is a large convex lens that can concentrate the sun's rays onto a small area, heating up the area and thus resulting in ignition of the exposed surface. Burning mirrors achieve a similar effect by using reflecting surfaces to focus the light.
The Burning Glass tells the story of Christopher Terriford, a British scientist who discovers a new method of capturing solar energy. This burning glass can greatly benefit mankind, but it can also be used to wipe out distant targets with devastating flame, so like the atomic bomb it holds the potential to destroy mankind. Because of this, Terriford won't give his discovery to the British Government, instead depositing half the formula in a bank and the other half in his wife's memory.
