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.
Artificial fusion has been achieved already. In fact it has been done in different ways. The problems with fusion include how to achieve it without consuming more power than is produced, and how to keep such a reaction going. The Farnsworth-Hirsch fusor is a fusion reactor a student might build as a project, but it sufferes these problems. Another problem with fusion is that many of the methods tried are expensive to test. The polywell is a reactor with such a problem. It is the result of many years of experimentation by Robert Bussard. According to Dr. Bussard, the polywell worked briefly before the apparatus burned out. Unfortunately he lost funding, and then died, and the effort is slowed as a result, so we do not actually know he was right. So the answer might be that we already have achieved practical fusion. We just have to determine that it is true. Or the answer might be that we have not achieved practical fusion, and if that is the case, it might be years or decades away.
Scientists will use the heat generated from nuclear fusion to produce steam, which will drive turbines connected to a generator to produce electricity. This process is similar to conventional power plants, but instead of burning fuels, fusion reactors will use the energy released from fusing atomic nuclei. Advanced technologies are being developed to efficiently capture and convert the energy from fusion reactions into electricity.
Fusion reactors have not been built yet because it is challenging to create and sustain the extreme conditions required for nuclear fusion to occur, such as high temperatures and pressures. Scientists are still working on developing the technology to make fusion reactors a viable and practical energy source.
The current problem with nuclear fusion technology is achieving sustained and controlled fusion reactions that produce more energy than is required to initiate the reaction. Scientists are working to overcome this challenge by developing advanced confinement methods, such as magnetic and inertial confinement, and improving plasma heating and stability techniques. Additionally, research is ongoing to optimize reactor designs and materials to withstand the extreme conditions of fusion reactions.
The main technical difficulty in dealing with fusion reactions is achieving and maintaining the high temperatures and pressures required to initiate and sustain the reaction. Scientists are working to overcome this challenge by developing advanced confinement methods, such as magnetic confinement in tokamaks, and improving plasma heating techniques to achieve the necessary conditions for fusion to occur.
The group of scientists who claimed they had achieved cold fusion was discredited and their results could not be replicated by other researchers. This incident damaged their reputation in the scientific community and their claims were dismissed as not being credible.
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.
Scientists want to harness fusion because they think it would be a new thing to do

Scientists talk about nuclear fusion, I don't think lawyers have any different words.
Nuclear fusion has not yet been achieved on Earth but it is the process by which the un and stars are believed to gain their energy. At the moment nuclear reactors use nuclear fission, which is the splitting of radioactive nucleii. Nuclear fussion is the combining, or the fusion, of atoms which would release much much more energy. Many scientists believe that this is the way we need to go to solve the energy crisis.
