These concrete houses in Dalian, China, are in some part thanks to Thomas Edison, who revolutionized the cement industry with his creation of the long kiln, Israel said.
In 1911 the inventor claimed that "men are lunatics" to keep building with bricks and steel, rather than concrete laced with steel reinforcing bars, or rebars.
"A re enforced concrete building will stand practically forever," he said. He also predicted that by 1941, "all construction will be of re enforced concrete, from the finest mansions to the tallest skyscrapers."
In the 1920s skyscrapers were largely steel-reinforced concrete, Israel noted.
100% concrete house is the next thing in construction and many developing countries are using this method specially China. In fact Swiftlet farm has been using this for long time. U see how advance Swiftlet farmer is!
Good Swiftlet farming all
