Natural gas is flammable too, that's the whole point of fuel. There isn't that much difference between using natural gas and hydrogen gas (except the hydrogen molecules are smaller and therefore need other materials to make the pipes and tanks gas tight, but this hardly new. Hydrogen has been used for decades in the industry).
Such a tank isn't very likely to blow up (unless you live in a Hollywood movie). Except when you happen to live in forest that decides to start burning big time. If the fire heats the tank, you can imagine what happens, assuming you're familiar with the ideal gas law pV=nRT, the volume V of the tank and the amount of gas n inside remains the same (And so does the constant R), The temperature T rises, So the pressure p doesn't have much choice than to rise as well.
p will rise until the tank bursts and some of the gas combusts.
If the same tank was filled with natural gas, the same thing would have happened. Even if it was filled with helium it would have burst (but it wouldn't have burned ofcourse).
All hydrogen released in the atmosphere floats up and collects at the edge of the atmosphere.
I believe this is the reason why you're not allowed to smoke on an airplane.
It's perhaps compareable to a chemical logic gate. The RNA letter changes the form of the active centre and it then can hold a single molecule with a particular orientation and bind it to the macromolecule.
In my oppinion it isn't real computation, just like a BCD to 7-segments encoder hasn't any computational power. It doesn't change the input, just translates it (the value 4 in binary or in 7-segments code means the same thing).
Actually, nanotech is more related to chemistry than electronics.
Nature has already solved that problem: ribosomes in your cells are actually natures nanobots. They receive a RNA string and based on this information, they contruct all sorts of macromolecules. They don't have any computational power or anything, it's purely chemistry.
I do expect someday to read an article about someone having his lungs ruined by nanoparticles. Not because they turned them into a VCR or anything, but in the same way working with paint can damage them.
Anyway if you ever meet someone who's affraid of nanotech, just inform them that there are already nanobots that can construct new nanobots and all sorts of complex chemical products.
Tell them there are millions just in the room he's in. Tell him running away is pointless, because they are already in his body, millions of them, every cell of his body is already infested by them.
And if he doesn't believe it, let him ask his doctor what ribosomes are.
Not me. I've got a beautyfull atletic body. My mommy told me that.
No, serious. I'm one of those people who are blessed with a body that keeps its ideal weight no matter what I do. (Probably until I meet my one special girl) And considering I live as healthy as the average American stereotype, that's quite impressive. (Perhaps I should start selling my genetic material. $10/handfull)
WHY Should I care in the least about censorship in China ?
Because you would like it if someone cared enough for you to call an ambulance rather than to steal your watch and wallet if you ever got into a serious accident. "Reap what you sow", couldn't think up a more appropriate title myself.
We've got something better. One of our channels has a new late night "show". Houres and houres of good looking girls in bikini jumping on trampolines. hmmmm. Life is good.
activity[69] is picking your nose. If you mean position 69, that's activity[167]. Now you know why numerical constantes are bad. Use the const-keyword.
That's bullshit. Our signals can't be blocked by a mere tinfoil hat. hahahahah, those people would believe anything... oh wait, is this thing still on? Damn. Better up the power on the slashdot brainwash signal. All is well; you want to buy more oil; Eat more meat; Bush is a great president; Cold fusion is imposible; Drive a SUV; The government is your friend; No one is spying on you; There's no camera in your toilet; All is well...
Not exacly. A permanent magnets field weakens over time. Basicaly a magnet consists of a huge number of small magnetic zones with their poles arranged in the same orientation. A non-magnetic piece of iron has it's magnetic zones oriented in random orientations so that the sum of all zones equals zero. So a magnet has a higher level of order and will lose this order gradualy because of external influences (like heat, shocks).
In your mouth ofcourse (be carefull not to get them wet). But you'll still have your right to free speech, well, for as far as you can give speeches with a mouth full of batteries.
A review? It's a book: Something happens to main character, a lot of other stuff happens, some more things take place, main character defeats King koopa and saves the princess and the butler did it! And they lived happely ever after, except for the butler who went to jail for doing it (she was underaged).
Why worry? I carry around a cellphone, MP3-player, PDA, laptop and an electronic watch. So I've got my own electromagnetic field to protect myself against cosmic rays.

oh and IANYAE (I'm not yet an engineer)

Don't be sad. Everyone around me got the I-love-you-virus...except me. :-(
It's realtime interactive porn without a computer.
