They got in big trouble
Wipeout Fusion happened in 2002.
It is not possible to give an answer as there is no practical design for a fusion power plant. So far scientists have been struggling just to achieve fusion in experimental apparatus. How the energy would be extracted if and when fusion can be achieved is not known, and to get an idea of its thermodynamic efficiency you would need to know this.
Two parent cells that join together to form a new individual is what is referred to as reproduction. This is achieved by fusion of the male and female gametes.
It hasn't been achieved yet, and it seems doubtful that it is possible. You may want to read the Wikipedia article on cold fusion to get a more detailed overview. To summarize it: the muon-catalyzed kind definitely is possible and is routinely done by researchers in the field - the problem is that it requires more energy to generate the muons than you can get out of the fusion. The Fleischmann and Pons kind appears to have been poor laboratory technique (I'm being charitable here, and not suggesting that it was deliberate fraud).
"Hot" nuclear fusion (this is not the term normally used) is exactly what the name implies, the materials are heated, which provides them with enough energy to overcome the normal repulsion of protons. Cold nuclear fusion requires no heating and has not yet been proved, although dozens of Physicists and Electro-Chemists have claimed to have created cold fusion. Cold Fusion relies on other forces, such as pressure, to overcome the electrostatic force of repulsion.
The scientists behind the controversial claim of achieving cold fusion in 1989 were unable to replicate their results consistently, leading to skepticism and criticism from the scientific community. Subsequent investigations found errors in their experimental procedures and data interpretation, discrediting their initial claim.

Nuclear fusion on earth has not been achieved in any way that could produce power, but experiments continue.
Dancing Stage Fusion happened in 2004.
Fusion - video game - happened in 1989.
None. Cold fusion has never successfully been done. People claimed to have done it, but it was a lie and it has been debunked as bad science.
Fission. Fusion can be achieved at room temperature and pressure , Fission (seems to) requires extremely high temps and pressures.

Nuclear fusion occurs at the core of the sun (and other stars) providing huge amount of energy to the rest of the solar system. It has also been achieved on Earth, though not in a controlled and sustained manner.
Fusion welding joins materials by melting them together, while non-fusion welding joins materials without melting them. Fusion welding includes processes like MIG, TIG, and arc welding, where a filler material may be added. Non-fusion welding methods, such as friction welding or ultrasonic welding, rely on pressure or friction to create the bond between materials.
