This graph explains very clearly how far away we are, and why it is taking so long. The reality is, with all the cheap coal (and natural gas), it's just not a priority. Besides, environmentalists hate nuclear so it's not a political winner to fund it. This story is good, too.
That looks like a graph that says 'fusion researchers want more money.' I want more money, too.
If I go to the source report, will it tell me:
1) the technical challenges they face?
2) if they're engineering problems requiring great expenditures?
3) If they're scientific research problems with uncertain outcomes?
4) If the research for a #3 problem involves a massive #2 effort?
