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 fourth answer we'll consider to the question, 'Who invented the first steam engine and in what year ?' is James Watt in the mid to latter part of the 18th century. Watt (1736 - 1819) is the one with the greatest name recognition among the inventors being considered here.
