Choose the right soil. Mulberry trees will grow on many types of soil as long as a good drainage system is provided. Ensure they are not in an area where flooding is common as they do not tolerate being engulfed in water. When possible, well-drained, deep soils are preferred. Opt for slightly acidic soil with a pH of 5.5 to 6.5.
Ancient steam turbines. Early in the first century A.D., a Greek inventor named Hero of Alexandria designed the world's first aeolipile, or primitive steam turbine. Heron's aeolipile consisted of a hollow sphere, mounted on a pair of tubes.
The Steam Engine. The creation of steam locomotives began with the development of the steam engine. The invention of the steam engine dates back into the late 17th century. In 1698, Thomas Savery, an English inventor, patented a device that allowed for the use of steam to pump water.
