Windmills
Although the windmills were invented in 1854, they existed before the time period. They looked different and were smaller than what we see now. Through time to time, as humans needed more out of it, they altered its size to make it perfectly fit into their needs. They were used for grain grinding, clothes drying, and after pumping. They are now used to produce energy.

Genetic Engineering
Genetic engineering is the process of manually adding new DNA to an organism. The goal is to add one or more new traits that are not already found in that organism. Examples of genetically engineered (transgenic) organisms currently on the market include plants with resistance to some insects, plants that can tolerate herbicides, and crops with modified oil content.
