Hmmm...as recently as a week or two ago, they were out and predicting August ship dates. Still, I don't think 450 units sounds all that impressive stock-wise.
My fingers are crossed. We'll see what happens.

At 68 cents, it doesn't look like the price went up

Come on Jack, it takes them 20 years to build a new tank, and that's with only one service involved. How complicated do you think the approvals will be with all of them sticking their collective oars in?

Grey,

Here ya go.

http://nepp.nasa.gov/whisker/background/#q6

I think the switch to lead free solder for the electronics industry is a hoax to make a few people rich....again. Consider that one improperly disposed of car battery will counter the ecological efforts of the no lead solder in domestic electronics industry for what, 10 years?

More smoke and mirrors folks, only now the mirrors grow whiskers and can short out, creating yet more smoke.

Virtually every statement in that link gives conflicting information--which they're graceful enough to admit. More to the point, I did not see any analysis of failure rates. Is it every device, one in ten, one in a hundred, one in a thousand...?
I repeat: I have yet to see evidence that leads me to believe that such an extreme viewpoint is warranted.
To say that one improperly disposed-of car battery negates the effect of lead free components and solder is poor logic. It's like saying that one improperly installed shingle negates the benefit of an entire roof. Yes, you may have a leak as a result, but a roof with a leak is still better than no roof at all.
Of course, you could simply dispose of the battery properly.
The entire problem exists for two reasons:
1) Although the toxicity of lead has long been known, no one anticipated that so much lead would ever be thrown away, or that it would leach into soil and acquifers. This has been exacerbated by the fact that things are no longer repaired--they're discarded.
2) No one thought to implement decent methods for recycling hazardous stuff to keep it out of the environment. This is a direct outgrowth of the first problem, but has become an issue in its own right.
Now, belatedly, and with much foot dragging by those whose profit margins will suffer in the short run (and those who are simply opposed in principle to anything that is inconvenient or different from the way they're used to doing it), we're starting to see sporadic movement on both fronts. I fully anticipate problems of one sort or another, whether it turns out to be tin whiskers or something else. There are always problems and tradeoffs. But there is not and never will be a perfect plan for dealing with everything. The best we can do is successive approximations.
Which is exactly what's happening now.
Think of it as negative feedback. The system is in error and a corrective signal is being sent to bring things closer to an ideal solution. We won't achieve 0% distortion, but it'll be better than it was.

Grey

P.S.: All of which leads me to wonder how gain devices feel about feedback. Do they resent it? Do they feel that they were doing just fine before the intrusion of that stupid feedback? I mean, really, no one likes criticism, even if it's "constructive" criticism.
Hmmm...
Might be a story idea hidden in there...lemme think about this.

Living near 6 coal burning power plants, three of which have archaic pollution controls and kick out 3 times the pollutants of the other three, I do think theres better places to put the effort. Tidbit: coal contains ~1ppm uranium and 2-4ppm thorium. If a hospital put out in a year what a plant does in a day, there'd be a hoopla. Its not old pcbs that give the fish here 100% of the US RDA of mercury.

A related pondering, how does the mercury content of a compact fluorescent bulb compare to the reduced mercury emissions from the energy savings?

That lead battery is just a smidgen of the car related environmental impact. At least its not using lead gas, Ethyl has to push MBTE now.

1) Were not citizens, were consumers.

2) Reminds me of towns objecting to people salvaging things from the recycling center rather than see it melt it down, see also: 1.

They respond with malicious obedience.

Vishay seems to have increased the wholesale price of the IRF HexFETs rather significantly.

Mouser has the Fairchild FQA19N20C in stock, but they weren't kidding...they only got 450 and they're going fast.
