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.
Steam Engines. The first steam-powered engine was invented in 1698 by Thomas Savery, although this machine was not intended for powering rail vehicles. Whilst the engine could be used for its intended purpose (raising water), there were several serious flaws in the design.
