So, I see this as rationalization.

The fact is, you took a leadership position, and later turned your coat for reasons that perhaps made sense to you. But they don't really make sense to anyone else. So, yes, everyone who supported you then is going to feel burned.

You also made yourself a paid voice that was often hostile to Free Software, all the way back to the SCO issue. Anyone could have told you that was bound to be a losing side and you would be forever tarred with their brush.

So nobody is going to believe you had any reason but cash, whatever rationalization you cook up after the fact. So, the bottom line is that you joined a list of people who we're never going to be able to trust or put the slightest amount of credibility in.

And ultimately it was for nothing. I've consistently tried to take the high road and it's led to a pretty good income, I would hazard a guess better than yours, not just being able to feel good about myself.

Comment Re:Why Cold Fusion (or something like it) Is Real (Score 5, Interesting) 350

Storms claims that there is no good theory to explain the excess heat measurements.

There is an excellent theory to explain the "excess heat" measurements: the people doing the research are some mixture of dishonest and incompetent. This theory also has the nice features that:

a) it is consistent with the spectacularly incompetent work we see whenever anyone attempts to carefully document an experiment, such as the one on the Rossi device we have seen recently

b) it is consistent with the litany of results that require well-established phenomenology to be turned off, for example the need to magically suppress neutrons and gamma rays that would otherwise be produced in any nuclear reaction or its aftermath, regardless of its origin.

After a quarter of a century with no reproducible results and no "positive" experiments that do not require the magical suppression of other laws of physics to account for the lack of radiation, no other theory is close to as plausible as this one.

Now I haven't seen anything convincing that indicates that cold fusion will work, but I also haven't heard of any significant investigation.

Cold fusion has been heavily investigated. There is one striking thing about all of the supposed "positive" results: they are physically impossible.

Suppose I said I had invented a car that ran on water, and that my claimed proof was that I had driven this car along the streets of a distant city. I give a talk on my results and show a map of the route.

A person in the audience interrupts and says, "Hey, I know that city! That's my home town! The route you've shown is impossible: you say you drove it between 4:30 and 5:30 PM on Tuesday June the 6th, which is in the middle of rush-hour, and you've shown yourself going the wrong way on half-a-dozen one-way streets! Why didn't you collide with anything?"

I reply: "This car runs on water! Weren't you listening? It doesn't collide with other cars, because it is propelled by water!"

You would be correct to suspect that you need not take my claims very seriously after that, and this kind of exchange is typical of cold fusion talks.

I saw Pons give a talk at Caltech, where one of my colleagues interrupted with the question, "Where are the neutrons? You say you don't see any radiation because all the energy comes out in high-energy alpha particles, but if you make alpha particles move with that energy through the palladium lattice you will get neutrons? Where are they?"

Pons answered: "New physics."

But alpha particles don't care what made them move, and more than a car cares what fuel it runs on. You can't just invoke "new physics" and say that the lack of neutrons or gamma rays doesn't matter, because you aren't really invoking new physics, you are throwing out old physics: you are saying that high energy alphas don't produce neutrons, even though that would require all of nuclear physics to be wrong.

So while I agree that new phenomena are often difficult to reproduce and we should be cautious about dismissing them on that basis, cold fusion, after twenty-five years of testing, has proven to be:

a) impossible to reproduce (there is no reliably reproducible experimental setup)

and

b) what experiments that have claimed positive results have always (to the best of my knowledge) required almost all of nuclear physics to be wrong to explain the absence of radiation.

I cannot think of any other phenomenon that eventually proved to exist that shares anything like this history of failure. Maybe Lister's work on sterile technique in surgery, which had a decade or two of rough handling? But even it was frequently reproducible, even if not universally so, and it didn't contradict any well-established, empirically founded, reasonably comprehensive theories of the time.

No, it really doesn't. It's too hard to transmit, and almost certainly will remain so.

Saying it has "the potential" to wipe out half of humanity is mindless fear-mongering. The US has more guns that people, and therefore it is true to say that guns in the US have "the potential" to kill everyone, but I don't see anyone panicking about it, just arguing whether 30,000 deaths per year is an acceptable loss. To use "potential" in the sense you are is almost completely meaningless.

Comment Re:SEALs possibly found WMD evidence early in the (Score 2, Interesting) 376

As to why, I can only guess.

You (or the SEAL books you refer to) make several contentions:

1) Iraq was actively engaged in new WMD production prior to the American invasion

2) The "diplomatic process" was intended (by whom?) to give Hussein time to hide this

3) The evidence as dismantled and relocated, likely to Syria

4) And the one we all agree on: the old stockpiles were found in Iraq

I've heard these claims before, particularly the one about Syria. The problem for anyone who takes this line of attack is explaining why the Bush Administration didn't put any of this together to make a case for the invasion and occupation after it was all discovered?

So what's your guess as to why the Bush Administration kept all this quiet?

Were they completely incompetent and let the military cover things up? If that's the case, why did the military cover things up?

Did Administration officials know all this--including the stockpiles etc being moved to Syria--and cover it up for their own reasons? If so, what were they? "A momentary lapse of reason" won't cover it. What is the plausible strategic, tactical, diplomatic or political reason for an Administration that made the invasion of Iraq a signature policy based on a pretext that was widely believed to be false to cover up evidence that would have proven that pretext substantially true?

This is the question that has to be answered.

Finally: if all the WMDs were moved to Syria, why are these WMDs still all over Iraq? (they were presumably in a lot better shape in 2002 than they are today, twelve years later.)

Comment Re:wow (Score 5, Insightful) 571

Third, fission leaves behind nuclear waste materials with a half-life in tens of thousands of years--this is nasty stuff and is around basically forever. Fusion produces no long-lived waste (there is probably some component of some alloy that will prove to make tiny amounts of bad waste, but nothing significant compared to fuel rods from fission reactors).

The critical thing to understanding this is that fission reactors are (necessarily) full of heavy elements, which is where the long-lived stuff comes from. Fusion reactors are full of light elements.

There are very fundamental physical reasons why radioactive light elements almost always have much shorter lifetimes than radioactive heavy elements. If you've only got a few nucleons to play with, turning a proton into a neutron is a major change in configuration, so the energy gap between the radioactive isotope and the adjacent stable isotope is large, and in general the lifetime against beta decay scales inversely with the fifth power of the endpoint energy. In heavy elements, which have so many nucleons they can be adequately modelled as liquid drops in some cases, changing one neutron to a proton doesn't change the configuration very much so the energy difference is small and the lifetime can be very large. Unfortunately, although the energy of the beta particle emitted is small, the energies of the other particles in the decay chain (gammas and more betas in most cases) can be pretty much anything.

So: heavy elements (fission) bad; light elements (fusion) good. Fusion reactors are designed with this in mind. They will produce a lot of nasty stuff, but almost all of it will decay rapidly, so given that the engineering issues of fission waste are pretty much under control (the political issues are not) we can be confident that fusion power will be OK in that regard.
