The work on nuclear fusion is broader than the tokamak approach you're alluding to. All other forms of fusion have had far lower levels of investment.
- duaneb 11y agoI'm not aware of any fusion reactor that has "broken even" with just collecting the energy investment. Until that happens, total efficiency for "nuclear fusion" is going to continue to plummet.
- ZenoArrow 11y agoIf some of the predicted timelines about excess energy generation from nuclear fusion turn out to be true then it'll work out to be cheaper than coal, even in the short-to-medium term after that goal is reached. It's too early to write such predictions off, unless you know something I don't know about the future.
- duaneb 11y agoAhh, this is what I was lookin for. Do you have a source for these predicted timelines? I'd like to dig in further. I wasn't even aware they existed.
