OSTI ID:5236910
A solar furnace is described which consists of a hollow tube having a light concentrating lens at one end thereof to focus light at the other end of the tube, a wooden base connected to the tube at the end of the tube remote from the lens. The base is removably attached to the tube, and having vertical holes therethrough, each of a different diameter. The focal point of the lens is within one of the holes, the center of each hole being equidistant from the center of the base, whereby rearrangement of the base will bring the lens focal point within the desired diameter hole, the lens being adapted to concentrate rays of sunlight within the space defined by the edges of such hole, whereby a tobacco product or fishing line can be inserted therein and ignited by concentration of the sun's rays thereon.
