Re: IAEA published idea: Diamond bullet into DT methane.

<t>As I understand it, the original scheme involves initiating a *propagating* fusion burn in the target. And thus only has to supply enough energy to light off a small portion of the target. Scale it down that much and you're trying to ignite the whole target at once, while your dense plasma is pro...

Re: Aluminium flange to steel sphere

It can be accomplished by spin welding, among other approaches, but that doesn't mean it's a good idea.

Re: Neutron Radiation safe distance assuming a 10^12 neutrons/sec break even?

<t>Correction: There is *assumed to be* no safe level for radiation. This is, however, an *hypothesis*, the Linear No Threshold model, and not definitively proven. The competing hypothesis, 'radiation hormesis", has a fair amount of empirical support, too. Not enough, though, that I'd keep Pitchblen...

Re: Neutron Field Nonuniformity

Or, it could mean a third thing: The fusor enclosure is modulating the neutron flux. It's not, after all, a uniform sphere, or perfectly transparent to neutrons.

Re: Why do metals smell?

<t>No kidding; The functioning of the sense of smell is pretty well explored, and is very closely related to the way the immune system generates a huge variety of anti-bodies, which is why the sense of smell can identify so many different chemicals. That "electromagnetic theory of smell" is quackery...

Re: North Korea Claims to Achieve Elusive Nuclear Fusion

<t>Schedule an above ground hydrogen bomb test, and I'll show up with an LED and solar cell, and accomplish just that. <br/> <br/> Fusion break even was an accomplished fact decades ago. It's just that the fuel pellets are inconveniently large. Nothing we couldn't build a plant to handle *if we had ...

Re: Lightning initated fusor

<t>I actually proposed doing something like that, (A zeta pinch through lithium deuteride, though; A fusor wouldn't benefit from the huge pulse.) as one of the events at a techie gathering some of my college friends used to put on. <br/> <br/> It was vetoed on the basis that it might work, and that ...

Re: Fusor as transmitter

<t>Use of a particle accelerator has two advantages over a fusor:<br/> <br/> 1. The neutrinos emerge in the form of a beam, much less inverse square loss.<br/> <br/> 2. You can control the energy of the neutrinos. The neutrino capture rate goes up with higher energies. So you could, theoretically, t...

Re: using microwave oven for Plasma generation

<r>Quite possibly. And blind you, if you haven't shielded the affair properly. The escaping microwaves will heat anything which contains water, and the inside of your eye lacks the circulatory capacity to remove the heat fast enough: You'll cook your eyes without even breaking into a sweat. And wake...
