NxtUp...Nazi Weapon?
Orbital Sun Gun
The Sun Gun was based on a design originally conceived by Hermann Oberth, a physicist who is widely credited as one of the founding fathers of rocketry and astronautics. In his 1929 book Wege zur Raumschiffahrt, or "Ways to Spaceflight," Oberth presented a scientific description of a hypothetical manned space station orbiting at an altitude of one thousand kilometers. He detailed potential construction methods using prefabricated sections, described a rotational cycle to produce centrifugal gravity within the station, and outlined a system for periodic resupply missions. Oberth advocated the development of these Raumstations to serve as astronomical observatories and telegraph relays, in addition to Earth-observing activities such as meteorology, search-and-rescue, and military intelligence. What interested the Nazi scientists, however, was his suggestion that a specially engineered 100-meter-wide concave mirror could be used to reflect sunlight into a concentrated point on the Earth. But whereas Oberth's design had peaceful intentions– to use the intense heat to produce electricity with steam turbines– the nefarious Nazis envisioned a colossal heat ray which could vanquish humanity.
