content: Many years ago there was a huge buzz about cold fusion, it interested me as I suspect it did many others, I watched the film chain reaction and whilst hollywood always misses the real facts and has a licence to do as it wishes for viewer excitement and income I liked it. Moving on a bit I read about Rossi on the wired web site and thought hmm, is it ever going to be a reality. Would be nice if it was but do you ever think it would be, if so what do you think of ultra mini reactors in mobile technology rather than batteries ?.I only just found out I can track a CPC parcel !, Doh, well I am old and bald as my best mate Tautech tells me but then he does sell Siglent kit so maybe he is as bad as I.In fact why is it I have to have a Farnell and a CPC account but have to fill in my details twice, why can't I use my acct number with either with the other , arghhh

content: We know the reaction cross section of every feasible fusion reaction. These impose a fundamental minimum on fusion. Cold fusion only ever works for atoms where the electrons are replaced by muons. Muons are heavier, which makes their "orbits" around the nucleus smaller. That in turn makes it easier to bring to nuclei together for a fusion reaction. So with muonic atoms, one could in theory have fusion reactions at comparably low pressures and temperatures. The only problem is, muonic atoms are difficult to produce and don't occur in nature. So NO, there won't be cold fusion batteries because the only way it could physically work, is not scalable. BTW the original cold fusion paper was a scientific hoax.

content: But with 10,000 muons per square meter of the worlds surface, harvesting must be an option sometime, technology advances, I like to think things are possible at some stage of evolution and advancement, look at the finding of the atom and then splitting it, as well as many other things physicists can do now that they didn't think possible before but merely theorised on.

content: The problem with atmospheric muons is their short lifetime. They only reach the earth surface because they have relativistic speeds. In our system of reference their decay time is shorter. As soon as you decelerate them (e.g. when trying to put them into an atom), they vanish.As for the science has discovered everything. Of course not, and there might be a hidden reaction channel, but the basics of fusion are almost as set in stone as the basic law of gravity. Saying cold fusion works in Deathwish's lifetime is like saying tomorrow gravity will reverse and things start to fall towards the sky.

content: Gravity is a good example since we still don't know what it is or how to artificially produce it. We only know it's effect and how mass creates it by warping space time.We know far more about magnetism than gravity.Only when we can produce an artificial gravity field electronically can we say we have a good understanding of gravity.

content: Well, we know that the generating quantity of gravity is energy density. That's why photons, amongst other things, interact gravitationally. The Higgs particle has been found, giving credibility to that particular theory of gravity. We know how gravity behaves. That's alerady a lot.And who says gravity can be produced by other means than a large energy density (which normally means matter)? We can't produce the electro-weak force artificially, either. We don't really know the fundamentals of electromagnetism, we just happen to be able to create it artificially, probably because it's less complicated than gravity. Theories of electromagnetism don't exclude monopoles, yet we haven't found or created them, ever. Saying we only really understand a thing, when we can produce it is one possible definition of the word understanding, nothing more, and one not everybody would agree with. Medieval people created a lot of stuff, they really didn't understand. Much of the nuclear reaction wasn't really understood, when we had the first chain reactions killing people. People didn't know what fire actually was until many thousands of years after its "artifical creation". There might be some fundamental things that can't be done and some that can, but can't be understood. Who knows? It's still worth trying though.Fact is as long as all the theories we have don't fit together perfectly without contradictions, we can't say, we understand anything. We can only say some theories are more useful for now. Doesn't make them better, more right or more fundamental. However, we can say gravity won't reverse its direction on earth for the next thousands of years. We can also say cold fusion will not happen in Deathwish's lifetime or mine. Because we know enough about how fusion works and we know enough about how gravity works for those statements.Not to mention that in battery size, you can't really have enough shielding from the neutron and gamma radiation of fusion. Not to mention you would activate the cells. So I'm very confident, that you and I won't see AA-sized micro fusion reactors in electronic devices.

content: I dunno, i wouldn't mind a few RTG around the house.100W for 14 years would be quite useful.
