USA Philadelphia Buckminster Fuller - from our story 'Arthur C. Clarke Predicts The World In 2100: Future Visions From 1964 and 2001'

In a Philadelphia, United States, office, on April 18, 1979 R. Buckminster Fuller holds up a Tensegrity sphere - one of his inventions that’s inspired a space project. Dr. Ernest Okress of the Franklin Center envisions the structure, made of rods and cables, as the basis for a Spherical Tensegrity Atmospheric Research Station – STARS. A giant Tensegrity sphere could be light and strong enough to support a floating space station a mile in diameter. (AP Photo/WGI)
