Petroleum or other solutions:
Petroleum is becoming more expensive these days due to the demand of petrol gas and diesel for engines or power plants. Its demand is increasing and the production is low or constantly decreasing. Scientists are working for alternate resources like electricity, wind energy, solar energy & geothermal energy. petroleum is refined easily by just boiling it at very high temperatures and different products of hydrocarbon compounds obtained.
Science of Robots and Machinery:
Robots are a good solution for automation because Robots can save time and money it also decreases the number of labors. Robots are also used for parts inspections, making glass, cleaning, monitoring radiation, sorting, loading and unloading, fastening, forging, and sand blasting. Because they are not human, they can be used in hazardous situations such as firefighting, military warfare, and bomb detection. Surgical robots are under development and robotic hands, for example, are already used in some surgical operations, allowing the human surgeon more control in laparoscopic procedures, those done through a very small incision. This century is well known for robots science & technology.
