What is Energy?

Energy is work. We feel the energy with its heat. Energy is measured in Joules. The physical economy is also measured with work, with Joules. The work done by a human, or a robot, consumes energy. An atom is inert energy, not creating work outside a body, yet able to organize itself in our body, to help us work.

Energy is not fully understood. Indeed, NASA discovered that there were statistically more and more stars in the universe, including big ones, proving that the universe creates not only life, but also energy. However, Kelvin falsified the work of Nicolas Leonard Sadi Carnot, to believe that there would be less and less energy. Kelvin is always taught. Nicolas Leonard Sadi Carnot is known outside France.

Knowing that energy creates work, the more we will compress energy in one point, the more we can do different jobs. We could not create a train with wood, called biomass energy, but with coal, called carbon energy. We can not create complex mechanics with coal, but with gasoline, called petroleum energy. We can not go to hypersonic speed with gasoline, but with nuclear fission, called nuclear energy. denser is the energy, less it will emit waste. Thus, low-density nuclear fission creates much more waste than dense nuclear fission. Dense nuclear fission can also recycle waste from previous plants.

My notes

Write about the beginning of Nicolas Leonard Sadi Carnot’s book.
