If achieved, it will be the cheapest energy source

 in my market on the timeline for nuclear fusion reactors:

He was scheptical about nuclear fusion not from an engineering perspective but from an economical perspective. I thought his comment made a lot of interesting points to bet on.

Option 1 means that at least a fusion reactor will produce energy and be connected to the grid

Options 2 and 3 resolve N/A if option 1 is No

Option 3 is slightly different than 2 as we cannot be certain about the future costs of other energy sources
