Focus Fusion On Google Tech Talks 141
Henning Burdack writes "Eric Lerner talks on Google Tech Talks about Focus Fusion, which would be a much cheaper and more feasible technology as a fusion energy source than any other current approach, based upon the dense plasma focus device. The technology will use hydrogen-boron fusion with direct induction of ion energy and photovoltaic conversion of x-ray emission, obviating the need of a steam-cycle and thus resulting in higher efficiencies. High temperatures of 1 billion Kelvin (100 keV) have been reached years ago. It only needs $2 million in funding and two years of research for a proof of concept, and maybe four more years for a prototype with positive energy output. In contrast to other fusion efforts it utilizes the natural instabilities of plasma instead of fighting them. Focus Fusion has been discussed on Slashdot before, and a patent application is also available, going a bit more into detail."

IMHO anyone interested in investing in this guy who is not a university or reserch institute should be extremely careful. Like put a radio ankle bracelet on him careful.

BTW he was banned for reverting libellous material and attempts to imply that things like joining a political organisation make him untrustworthy (well, I suppose he was technically a politician, so maybe he was) and for bigging himself up too persistently - the latter only proves he's a self-righteous arse - so often a problem for scientists.

No he's not, the cosmology theory is by a nobel prize winning cosmologist. He wrote a book to publicise the theory.
> denial of quasar as blackholes
There is no evidence that they are black holes. They a big and dense. It is not known whether or not they have a large mass behind an event horizon entirely separated from the rest of the universe - we merely have no popular theory to establish that they are not black holes but that doesn't make them so. Assertions that they are and must be black holes and that alternative theories makes you a "DENIER" is far more crackpottish.

What does that have to do with his theories on the use of established fundamental quantum limits on bremsstrahlung and synchrotron radiation for sustaining plasma energy in a DPF plasmoid?
Yes, lets all stop doing science... Damn that science.

One factor of many: plasmas are prone to a host of instabilities, and 'stability' usually involves tradeoffs between one type of instability and another. So when somebody tells you "my plasma is stable", it should set off warning bells. The honest man will tell you the limits of stability.
As Artsimovich put it so eloquently in 1961, "Initial belief that the doors to the desired region would open smoothly at the first powerful pressure exerted by the creative energy of physicists has proved as unfounded as the sinner's hope of entering Paradise without passing through Purgatory. We do not know how long we will be in Purgatory."
We got into the Space Age by way of the Cold War, but what will push us into the Fusion Age?

I have no idea whether there's any chance focus fusion could work. But I do believe it has probably been a terrible mistake to have put all our eggs in the tokamak basket for all these years. When you don't know how to solve a problem, it's critical to keep exploring alternative approaches, especially if they're radically different. I would love to see substantially more funding for focus fusion, electrostatic confinement fusion, sonofusion, and even good old Pons and Fleischmann style cold fusion. The total would still be small compared to tokamak funding -- and who knows, maybe one of them would work out, or maybe we would learn something that turned out to be useful in the tokamak.
While there certainly are crackpots out there, I think we're too quick to dismiss ideas outside the mainstream, too eager to congratulate ourselves for knowing the truth already when we clearly don't know all of it. We need to cultivate more humility in the face of the mystery of the unknown.
