Factory pattern should be used when: - a framework delegate the creation of objects derived from a common superclass to the factory - we need flexibility in adding new types of objects that must be created by the class. Along with singleton pattern the factory is one of the most used patterns.
In thermodynamics, the term exothermic process (exo- : outside) describes a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light (e.g. a spark, flame, or flash), electricity (e.g. a battery), or sound (e.g. explosion heard when burning hydrogen).
Fusion Energy Release. A large amount of energy is released by nuclear fusion reactions. It seems that for power generation, the deuterium-tritium reaction is the most practical, but it provides most of the energy to the released neutron. That is problematic because it is harder to extract the energy from neutrons compared to charged particles.
