Thomas Edison, the famous American inventor, is well known for his inventions like the light bulb and the phonograph. However, what many people don’t know is that Edison was also obsessed with concrete. In 1908, he filed a patent for constructing buildings with a single placement of concrete, which was ahead of its time. Edison even founded the Portland Cement Company in 1899, although it struggled and eventually went bankrupt. He also came up with the idea of building homes out of cast-in-place concrete, which he saw as a solution for housing shortages. Despite his efforts, the concrete houses were not widely accepted, and his concrete endeavors ultimately failed. Nevertheless, Edison was ahead of his time and predicted innovations in affordable 3D-printed housing.
