The Nazi Plan To Build A Deadly Sun-Reflecting Space Mirror

On a more peaceful note, the device would also be used to turn the Arctic and Antarctic poles into verdant gardens. Via io9:

In 1945, Life magazine revealed how “U.S. Army technical experts came up with the astonishing fact that German scientists had seriously planned to build a ‘sun gun’…a gigantic orbital mirror that would “focus the sun’s rays to a scorching point on the earth’s surface.” The German army, readers were told, “hoped to use such a mirror to burn an enemy city or to boil part of an ocean.”

The idea had been originally proposed by the seminal rocket scientist Hermann Oberth in 1923. Oberth thought it might take ten to fifteen years to assemble a complete mirror at a cost of $3 billion. The pressure of sunlight on the vast surface would be used to maneuver it in orbit, with steering accomplished by adjusting the angles of the individual mirrors. As late as 1957, he was still convinced that his space mirror would become a reality.

The nearly 5000-square-mile mirror, he said, would create a bright, heated “spot” on the earth’s surface about 2000 square miles in area. This heat and light, he admitted, would be “no stronger than that normal at the equator.” But, he went on to say, if “the mirror were double the size mentioned…the irradiation would be four times as strong…The temperature on the surface…would be 392°F.”

      considering the source, I think you mean
      the Homeland Nazi’s tend to think outside the box
      when it comes to bullshit propaganda that serves no useful purpose

        all propaganda serves some purpose even if it is just a trial run to see what will work.
        I miss WW2 so many oddball plans and strange ideas, today they have taken all the fun out of war

    I feel a Bond movie coming on.

  5. You can find our own plot to build a giant magnifying glass in space in the NASA archives. It cracked me up when I read it. It reminded me of something off Looney Tunes.
