Fuller’s Fog Gun
was great at dreaming up inventions that, he hoped, would help humanity by making people's lives easier and less stressful. However, most of them never caught on. One of his ideas was the fog gun.
The basic concept was to combine the cleansing effects of wind and heavy fog. His system used compressed air, atomized water and liquid soap. Standing in the blast of this "fog gun" for approximately ten minutes would completely clean a person. From buckminster.info
His fog gun....afforded a new kind of bathing. It combined compressed air (over 200 pounds/square inch) and atomized water with triggered-in solvents. The kinetic force of the high-pressure air stream was utilized without the skin-damaging effect unavoidable in high-pressure needle-pointing of water streams...
The best part was that you could leave the fog gun running for an hour, and it only used a pint of water. And, "If fog gun bathing were done in front of a heat lamp, all the sanitary & muscle-relaxing effects of other types of bathing could be effected without the use of any bathroom."
Fuller described the fog gun in his first book, Nine Chains to the Moon
, published in 1938, the title of which referred to the idea that if all the people in the world stood on each other's shoulders, they would form nine chains to the moon. Back then the world's population was about 2 billion. Now we're at over 6.6 billion, so presumably we're looking at about thirty chains to the moon.
