What is the meaning of Fusion ?

In March of 1989, two University of Utah electro-chemists, Stanley Pons and Martin Fleischmann, reported that they had obtained evidence for the occurrence of nuclear fusion at room temperatures (i.e., cold fusion). During the electrolysis of heavy water (deuterium oxide), it appeared that the fusion of deuterons was made possible by the presence of palladium electrodes used in the reaction.

If such an observation could have been confirmed by other scientists, it would have been truly revolutionary. It would have meant that energy could be obtained from fusion reactions at moderate temperatures. The Pons-Fleischmann discovery was the subject of immediate and intense scrutiny by scientists around the world.

. A number of alternative explanations were developed by scientists for the apparent fusion results that Pons and Fleischmann believed they had obtained and most researchers now assert that Pons and Fleischmann's report of "cold fusion" was an error and that the results reported were due to other chemical reactions that take place during the electrolysis of the heavy water.

A fusion of different qualities, ideas, or things is something new that is created by joining them together.

In January 2003, the United States rejoined the International Fusion Program, an international effort to construct an experimental fusion reactor. Recent progress in controlling plasmas and developing technologies for burning plasma reactors may eventually provide a workable containment system.

The fusion of two or more things involves joining them together to form one thing.

Fusion is the reaction where two lighter atoms join to form a heavier one. When under the right conditions two nuclei fuse together, a remarkable thing can happen. The total mass of the resulting fused nucleus is just slightly less than the separate masses of its components, and the difference is released as energy. This makes fusion very powerful. It is the reaction that powers the sun and that occurs naturally in all stars.

The simplest fusion reaction starts with a Hydrogen nucleus, a single proton. Protons have positive electric charge and repel each other. But if you squeeze them together hard enough, the 'strong' binding force overcomes the 'weak' electrical repulsion, and the two protons fuse to form a hydrogen isotope deuterium.

Fusion, or synthesis, is the process of combining two or more distinct entities into a new whole.
