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 first self-propelled steam engine was invented by James Watt, with the help of his assistant William Murdoch, over 60 years after Savery trialled his designs. They were able to create a working model, but they did not produce a full scale locomotive which was able to pull wagons.
