Princeton Nuclear Fusion Reactor Will Run Again

mdsolar writes with good news for the National Spherical Torus Experiment. Tucked away from major roadways and nestled amid more than 80 acres of forest sits a massive warehouse-like building where inside, a device that can produce temperatures hotter than the sun has sat cold and quiet for more than two years. But the wait is almost over for the nuclear fusion reactor to get back up and running at the Princeton Plasma Physics Laboratory. "We're very excited and we're all anxious to turn that machine back on," said Adam Cohen, deputy director for operations at PPPL. The National Spherical Torus Experiment (NSTX) has been shut down since 2012 as it underwent a $94 million upgrade that will make it what officials say will be the most powerful fusion facility of its kind in the world. It is expected to be ready for operations in late winter or early spring, Cohen said.

Re:Public cynicism about fusion

You seem to be perfectly willing to sell out the long term future for the medium term, which is the weirdest case of short-sightedness I've ever seen.

And at this point, I think you are deliberately misstating my argument. Fusion is a dream at this point that the most knowledgeable in the sciences say is at least 60-80 years away from economic viability. Don't believe me? Look at the ITER roadmap, publically available. And the reality is that the visionaries are usually overoptimistic. You and I will be dead before it becomes viable and our children as well. And that is assuming this becomes viable as there is always a risk when talking about advanced tech like this. Even if you are convinced the science will work out, political upheaval could mean that we can't see the project through to the end. Just imagine a more indebted US and Europe having to cut science and a China that no longer has a market to sell to and collapses on its own centrally managed bureaucracy. Insert your own worst case scenario and you see why century long, multi billion dollar research projects are risky.

So, fund it? Sure. But not at the expense of something that is a sure thing and will have a huge benefit now. You state that solar is somehow selling out the long-term... unless you mean over a billion years from now when the Sun goes nova, I'm not sure how this is remotely accurate.
