I am not a physicist, so I do not know if my comment is welcome here (the title of this thread does not imply that it is only about physics' research projects). I like to think of myself as an engineer, because I work mostly on macro things with occasional dips into the micro/quantum ones, figuring how to use them to solve practical problems. Using computers telecommunications and artificial satellites to map in detail the gravity fields of the Earth,Moon and planets, for example, which is a form of knowledge that has many different applications in geoscience and engineering.
And perhaps further not welcome, but here it goes: I would like to understand better the possibilities of realization of the until now elusive practical, everyday production of fusion-driven electric power and its prospects of ever becoming something that generates much, much much more energy than it consumes and does not require gigantic installations and engines with experimental huge lasers and huge plasma containment devices, so not something looking like the current large tokamak-like ones. Among other reasons, because if this became feasible, it might very well prolong the existence of a civilized humanity for centuries to come.
Not a life project for me, but perhaps someone else here might decide to take it up?
