If you could compare all the different applications of clean technology (solar, wind, etc.) to horses in a race, I guess you could say that Nuclear Fusion is the ‘long shot’. It’s the old nag that everyone expects to come in last, if it comes in at all. But, as long shots do, if it does come in the pay-off would be huge.
Often slated to be a fifty year project, the time-frame has recently been chiselled down to a ‘modest’ thirty years – maybe.
