TreeHugger loves rainwater harvesting; we think everyone should do it. Most systems are pretty industrial, but what do you do beside your English cottage or American monster Tara knockoff when you need a tank (or in the UK, a water butt) that fits in? Perhaps a classic Doric column made of polyethylene will do the trick. Buy four and you might hold up the porch roof with them, although the proportions are a bit off. ::Greenfingers via ::WeHeartSheds
Pittsburgh's US Steel Building has exposed exterior steel columns filled with water. They did it for fire protection, but perhaps water filled columns will make a comeback?
Ground was broken for the US Steel Building in March of 1967. The United States Steel Corporation, one of the largest steel producers in the world, wanted to make a statement about the strength and beauty of steel. The original concept was to design the tallest building in the country, with an outer facing completely made of Cor-Ten Steel. It was to be a huge advertisement for the steel industry, which was centered in Pittsburgh.
The building was completed in 1970 and became headquarters of U.S. Steel Corporation. The towering 64-story skyscraper did not quite eclipse the tallest buildings in the country, but in 1970 it was the third tallest in the land, behind the Empire State Building and the Sears Tower. The steel tower rose to a height of 841 feet, well above 600 foot Mount Washington, and is visible from the South Hills.
It was the first structure in the nation to use liquid-filled, fireproofed columns as a safety feature. The 18 support columns are filled with a mixture of water and anti-freeze. It was the best the steel industry could produce, remaking the Pittsburgh skyline and towering over the city landscape. ::SpdOnline
