I'm not up on the challenges and thought fusion was accomplished long ago. Are you just referring to the contained and controlled process as a nuclear power generator?

If so, what are the challenges and failures associated with Fusion Nuclear Reactors?

Thank you for any insights.

You are correct, fusion as a process is actually very simple and well within the reach of even hobbyists if you have a 30,000 volt power supply, a simple vacuum system and a small bottle of deuterium. However, using fusion to produce more energy than is consumed by the apparatus and on a continuing basis is the elusive part.
