Comment Re:Nice from a tech point of view, *BUT*... (Score 1) 226

Butanol seems to be a good option here - similar energy density to gasoline and can be used neat in any vehicle without modification, so no limits to blending either. I think there's a push at the moment to retrofit ethanol refineries to produce it, but I have no idea whether that technology's applicable here.

Comment Re:Fusion Confusion (Score 2) 556

Isn't the problem here that it's kind of difficult to produce muons efficiently enough? Fusion is definitely possible when you have muons, it's just not currently possible to get more energy out than you put in and nobody seems to have demonstrated anything that's likely to change that in the near future.

So I've been trying (with minimal success) to find any quality information on this, but there are a few bits and pieces out there.

My understanding is that the most likely theory here is that there's a low energy mechanism for generating neutrons in condensed matter via 'heavy' electrons (high effective mass due to lattice phenomena), and that these neutrons can be used to trigger energy producing reactions (there's a lithium based cycle with no net consumption of lithium, for example). The reactions themselves aren't new, but producing neutrons cheaply enough to generate a net energy gain is. I don't have enough of an understanding of the theory to really judge how feasible it is, but the idea that electrons in lattices can behave in interesting ways (c.f. superconductivity) isn't crazy enough IMO to dismiss the idea outright.

I think this is relatively orthogonal to Rossi and Co., although I believe there was some interaction between him and NASA at some stage. He's definitely mishandled the public relations around his announcement, is likely out of his depth in terms of understanding what he's doing and may well be attempting fraud. That doesn't change the fact that there may be some worthwhile science to be done in the field.
