Presumably Snowden, being an intelligent guy, kept copies of those emails he said he wrote and will be able to produce them one day.

I doubt it. If he had he would have produced them by now. There is no advantage to waiting.

His claims about making complaints are nothing more than a cover story, a sugar pill to make his massive betrayal of his country palatable.

Of course he betrayed your country too, but you would cheer him for that given your politics.

Perhaps the ability to pick up the sound without outside interference too? Or the fact that the MEMS creates more or less a digital signal by default?

Actually, it likely isn't doing anything with sound in the traditional sense. The MEMS microphone is pressure sensitive so it is likely not listening for breathing but measuring pressure differentials when breathing occurs. This could aid speed because you could close your lips and move your tongue or mouth or even flex your throat to force air through your nose to do the Morse code quicker then short bursts of breathing. In this case, air pressure would be different with air moving verses not moving even if just by minute amounts. Although the article says distinguishable breaths so I may be wrong on it.

You don't know what you are talking about. It is common for military investigators to need a warrant to search the property of service members. It isn't rare at all.

But you should be clear there isn't a universal requirement for warrants to search civilians even for civilian police. There are a number of exceptions in fact.

It's "stupidly easy" to calculate radiative power out and power in through what boundary? The boundary you're describing has to include the source's radiative power passing out through it, without including radiative power from the chamber walls passing in. I think that's impossible, but feel free to explain exactly where such a boundary would be drawn.

Are you REALLY the moron you make yourself out to be? NET radiation from a cooler surface that passes the boundary is reflected, transmitted, or scattered and passes right back out through the boundary. This is a corollary of the Stefan-Boltzmann radiation law, which states that NET heat transfer is always from hotter to cooler.

You can draw the boundary right around the heat source. Electric power comes in, radiative power goes out. There is no contradiction, and no inconsistency.

Once again, I agree that "power out" through a boundary drawn around the heat source is given by the Stefan-Boltzmann law. But I've obviously failed to communicate that the power from the chamber walls has to pass in through that boundary, so you're only using half the equation to calculate the electrical heating power.

And again: by that same law, it just passes right back out again because the same NET amount of radiative power that crosses the boundary and intercepts the smaller sphere is either reflected, transmitted, or scattered. (Since we are discussing diffuse gray bodies here, we can consider it all reflected or scattered because there is no transmissivity.) The radiation that crosses the boundary that does not strike the smaller sphere due to view factor also just passes right back out. You are ignoring (e*s) * (Ta^4 - Tb^4). Anything other than what I described does not add up.

Once again, no. Draw a boundary around the heat source: power in = electrical heating power + radiative power in from the chamber walls

Just NO. Net heat transfer is ALL from hotter to colder, by (e*s) * (Ta^4 - Tb^4).

Let me put it another way: we can easily show how you have gotten your thermodynamics backward by referring to a question you asked earlier. You asked me if I believed the power usage of the heat source would be the same if the walls were also at 150F.

The answer is YES, and here is why:

You are proposing to bring the whole system up to a level of higher thermodynamic energy, rather than just the heat source. And you are somehow proposing that it doesn't take more energy to do that. But of course it does.

The power required to bring the heat source up to 150F remains the same, because the Stefan-Boltzmann law says it has to be. But NOW, you are ALSO bringing the walls up to that higher temperature, and THAT would require even more power (because of the slightly larger surface area).

This clearly illustrates your ass-backward thermodynamic thinking. The radiative power output of the heat source does not change due to the temperature of the walls. At all. The only thing that changes as the wall temperature changes is the heat transfer, which would lessen as you brought up the temperature of the walls. But that isn't because the heat source is using less power, it is because you are putting more power into raising the wall temperature. You are creating a more thermodynamically energetic environment, and that requires power.

Just like your other arguments: you invent power in out of thin air, and claim you can do that because it's "moving" in the opposite direction in which heat transfer is actually taking place.

You are giving physicists a bad name, and I repeat that I am going to show this to all the world to see.

GISS is precisely the dataset that has been accused of the the most egregious "adjustments".

Further, it was recently found that GISS was improperly averaging in "missing" data over a period of years, which they admitted to about 2 months ago.

It is interesting that the historical HCN data disagree quite a bit with the modern versions of the data sets.

And even then... Tesla doesn't have to deal with the dealerships. That whole model of sales is obviously going to come under challenge from all the other car companies now that will all ask "why do we have to deal with you when Tesla can do what they want?"

Maybe Toyota or Ford will want to have their own stores. And the dealerships are going to have to justify themselves to those organizations.

They would have to cancel all their franchises first. The State Supreme Court ruling said they couldn't sue Tesla because Tesla were not franchised Tesla dealerships. So if Ford or Toyota had franchised dealerships- they would have to get rid of them first in order to sell direct.

Tesla could open franchised dealerships and sell in the states they are restricted in. But my guess is that margins are paper thin and they do not think the markup necessary for franchised dealerships would be attractive enough to sell the cars.

If Microsoft pulls it off right, they could even get positive mindshare, or at least some goodwill with the youth demographic out of this.

If you check the Minecraft forums today, there are some very hardened anti-Microsoft players venting in the 'MC buys MC' thread. Filtering these people out and actually earning some cred with other portions of the community would be gold for Microsoft. Also, if Microsoft bungles it, the fallout will be more severe than the marketing people at MS could imagine.
