They are bogus. Energy storage per Kg is much lower at this point for ultracapacitors than it is for batteries - so any claims of more mileage from them over batteries is VERY suspect.
This isn't to say they aren't very useful in automotive applications - they're very good at storing and releasing energy very quickly and efficiently (much more so than batteries). But that's a different figure of merit.
In addition, if you sample at 44.1Khz and there is a signal with a frequency above that, it's not filtered out - it will get aliased down to 44.1Khz - freq. So you need the analog filtering before the sampling to prevent this. And analog filtering always has a rolloff, it is not infinitely sharp (a consequence of the Kramers-Kronig relation - a step cutoff filter will respond to a unit impulse before it is applied.)
Now, I'm as voraciously against computerized voting as anyone (I voted in DC today, and you now have a choice.) But this is NOT the fault of the voting machine per se, but of the people who forgot to pack the damn cards in the box. If they forgot the paper ballots, they'd have the same problem. Let's be careful not to use a poor argument against this type of voting system when there are so many good arguments out there. It just gives proponents of electronic voting an easy straw man argument to tear down.
If you have air in the gas lines, the RF power is going to be the least of your worries. It'll explode when it hits the customer's pilot light. The only reason the flame from your gas stove doesn't jump down the gas line is that there is a negligible amount of oxygen.
I just went and looked at the web site. As a business proposition, it's useless to me. I would be interested in buying kids programming (kids like watching the same thing over & over & over & over...). I can't burn it to a disk to play on my DVD player, so my kids can't watch it in the living room or in the car. Also, we have Macs at home.
If it was unencumbered, or even if I could burn only a single DVD, it would be well worth the $2 per episode of Blue's Clues. Nor would I download it off the internet, even if it was freely (although illegally) available - so even if some jerk posted it up on their website, amazon wouldn't lose my business. But they're not getting it now, because I can't use the service like it is.
So the question is, would they make more money from people like me, who would gladly pay for a legitmate copy I could use (even in the face of easy illegal alternatives), or are there more people who would forgo buying a legitmate copy because an illegal copy was available? That's the business decision that needs to be made.
As I can't handle a single sheet of paper for more than about 5 seconds without rendering it to wrinkly and/or coffee stained to use in the printer again. Now if they made some sort of permanent press paper that did this, THEN I'd be excited.
I was the opposite kind of student - I went to all the lectures and never read the book. (I majored in physics - I wouldn't try this in a literature course!) I think that my classroom experience would have been diminished if many of the students weren't there. Between questions people asked in class, questions I asked in class, and conversations with the prof and other students before and after class, I would have missed out on a lot.
I find I have mixed feelings about this report since I recently lost my cousin (29, non smoker) to an aggressive lung cancer. It's great, but couldn't it have come sooner?
When I saw them in costco, I bought a bunch and replaced about 80% of the lightbulbs in my house with them. The remaining bulbs are where my wife sits and reads, and she doesn't like the light from the CF, although I can't tell the difference.
The soul accumulates judgement so that things may be evened out. If not in this lifetime, then in the next, either through the mechanism of impartial karma or through a divine Judge. Justice prevails. This, to me, is the primary purpose of the concept of the soul.
A reading of the Bible (I'm Jewish, that's the Old Testament to Christians) doesn't reveal any mention of an afterlife or souls - at least not the first five books. One theory I've heard is just as you describe it - that the concept of an afterlife was deduced by early thinkers from the premise that there must be justice in the world, and it explains why sometimes good people suffer and evil people prosper. I am not nearlty knowledgable to be sure if this is true, perhaps there are some talmudic scholars out there?
I personally take the view that whether or not there is an afterlife doesn't affect how I should act, so it's not something to worry about too much.
Si can be used for photodetectors, but as an indirect bandgap material, it is very difficult to get it to generate light. Also, glass is SiO, not Si. Also, the big trick with optical waveguides is getting them to turn sharp corners so you can fit a reasonable number of interconnects on a chip.

This is a "believe-it-when-I-see-it" thing - it's such a leap of technology (if true), that I'm prone to skepticism until they demonstrate the device.

Hey, I had the weight problem too, so I switched to enriched uranium. It's a lot more valuable pound for pound, so it doesn't weigh me down so much.
In fact, we only eat prewashed spinach, cause I don't like sand.
I sing along to Meat Loaf's "Bat Out of Hell" album when I'm doing circuit layout!

Except for the beatings.

Yes, plus the sewers having a lot of water in them would tend to degrade the wireless signal...
I love Netflix - but boy would I love to see them lose this suit bigtime.

It's trespass when you send enough emails to affect the functioning of someone's server. A single email wouldn't cause this problem.
Lifetime, heck - capacitor and resistor values can significantly drift over temperature.
Cancer really sucks. I hope this pans out.
I guess a 'grammer' would be someone who only ways a gram...

I bet I know where they got their scientists.
I do the same thing. Except every six to twelve months, I move all the emails to a different folder. I have most of them going back several years.

Well, spamming isn't a crime worth pursuing, but now they've crossed the line into copyright infringement - boy, are they in trouble now!
