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.
George Corliss was not the inventor of the modern steam engine. James Watt is largely identified as the father of the modern steam engine. The watt, a unit of work, is named after James Watt. George Corliss is important as he invented a shuttle type valve which allowed the steam engine to be very efficient.
