“Yellow-green light of 5500 Angstroms, for example, generally emanates from material of about 10,000 degrees F (5700 degrees C), which represents the surface of the sun. Extreme ultraviolet light of 94 Angstroms, on the other hand, comes from atoms that are about 11 million degrees F (6,300,000 degrees C) and is a good wavelength for looking at solar flares, which can reach such high temperatures. By examining pictures of the sun in a variety of wavelengths – as is done through such telescopes as NASA’s Solar Dynamics Observatory (SDO), NASA’s Solar Terrestrial Relations Observatory (STEREO) and the ESA/NASA Solar and Heliospheric Observatory (SOHO) — scientists can track how particles and heat move through the sun’s atmosphere.”
Look at the schematic carefully, and you can just picture the proceedings. First you have the service in the room with the seats; then the casket would ceremoniously rise to the roof; whereupon a crane would lift it into the path of concentrated solar energy.
“A temperature of about 1,700° F. is required to provide incineration and a total of about 3,000,000 BTU’s is required to consume a corpse. Thus, at a supply rate of about 1,000,000 BTU/hour, cremation would take about three hours. A concave mirror-reflector bowl similar to the steam-producing Crosbyton hemisphere in Lubbock, Texas is considered a suitable collector. At 65 ft. diameter, a bowl of this type can produce approximately 1,000,000 BTU/Hr. under full sunshine conditions from mid-morning to mid-afternoon.”
