Calling something energy positive can be done in a lot of creative ways.
​
Fusion on earth only really works between tritium and deuterium. Problem is that tritium is not found in nature and you need to breed that, in a nuclear fission reactor so that is costing additional energy.
​
Then if you build a plant, there is all sorts of auxillary systems that require power, think coolant, HVAC, control systems etc etc.
​
Then the next hurdle even if you manage to get a net gain in energy, there is commercial viability. You need a army of technicians to run your facility, the plant has a limited lifetime in which it needs to offset it's building cost.
​
It will probably be viable somewhere in the future but I don't expect it during my lifetime.
