QuoteQuite a discouraging future we face from these media star "genii" who have conducted few if any experiments of note. But they "advocate hot fusion research", Cude contends.
This is a reference to an interview (maybe a questionnaire) in the Guardian in 2010, when they were asked what problem "do you hope scientists will have solved by the end of the century", and they both answered the extraction of energy from nuclear fusion, but made no mention of LENR at all. (And just to provide context, around that time, Cox did a documentary on BBC's horizon on fusion energy research, and did not mention cold fusion.)
The point was merely to show that prominent scientists, one of whom is extremely active in public outreach, essentially ignore cold fusion research.
QuoteAfter many billions of dollars of funding, and over half a century of promises that controlled [hot] fusion is but "20 years away".
I did not intend to get into a hot fusion discussion. I am not qualified to argue the technical merits, and prefer to leave that to the experts consulted by the funding agencies.
But 20 years is optimistic. 50 years is optimistic. This century is conceivable. But if it works, it will be worth the wait. It's clear we need to find alternatives to fossil fuels *other* than fusion to bridge a gap, or possibly forever. But it seems to be worth the gamble to continue to work on hot fusion, even if no one living will benefit. I'm just that nice a guy. It would be a shame if a century from now, the world decides that all the energy sources suck, and to have to start researching fusion then, and have to wait another century for results.
QuoteSo, another $100 billion or more, and another 60 years.....
If it works, that would be a bargain. In the US, the fusion budget corresponds to about a dollar per person per year. That's a reasonable gamble for the holy grail of energy sources, given the solid scientific foundation, and clear unequivocal progress.
QuoteBut, in spite of its dismal history, hot fusion research remains a billion dollar a year "industry". One of many continuing legacies of the Cold War it would seem. One of those enterprises that military decision makers, DOD contractors, particle physicists and their lobbyists can continue to deceive the public and their politicians into "patriotically" supporting.
The history is disappointing, but not dismal. In contrast to cold fusion, it has shown quantifiable progress with each iteration increasing the value of the all-important triple product. In fact, it has done better than Moore's law in fusion research. Check out figure 3 at http://rsta.royalsocietypublishing.org/content/368/1914/1091 for a graphical representation of the progress.
Considering that exploiting hot fusion requires no fundamental breakthrough, and considering the clean and abundant nature of the source, to me, it doesn't matter if it takes a century or two and if it costs 50 times more. We should look ahead and spare a thought for our descendants, because it's doubtful anyone living will benefit from fusion power (other than solar).
More is spent on research into erectile dysfunction than fusion. Subsidies and costs of wind and solar are a hundred times higher. The NASA budget is a hundred times higher, and the lion's share that has gone into human space flight, which has a far more vague and distant benefit than fusion power.
Now, if the (nearly) unanimous view of experts were that the practical problems had virtually no chance of being solved, or even being economically feasible, I'd have no problem seeing it all shut down. But that's not the case. There are delays, and escalating costs, but the general view remains optimistic. In that scenario, such a tiny amount of funding for a technology that could revolutionize a trillion dollar industry seems well worth it.
