As of April 2013, the odds of a Mars impact are about 1 in 8000. Looks like it may pass within the orbit of Deimos, but probably not, due to the remaining uncertainty.
If the tank isn't kept ultra-cold (i.e. it's hot outside) it explodes.
Pressure relief valve. It's mentioned in the link. The article is discussing liquid Hydrogen, which is not being discussed for use in cars.
As you burn hydrogen, pressure drops, the hydrogen in the tank cools the metal ridiculously.
1. How fast do you think the Hydrogen is being released? Under normal conditions, normal thermal transfer should keep the tank warm. 2. If it's a problem, waste heat will be used to warm the tank.
And what's with this mass/volume of storage? That's good if you need transport, but not necessarily efficient to produce--gasoline could be 20 times as efficient and it would be 100% useless in space versus 2% efficient hydrogen. How do they compare?
Not sure what you mean by this- why would a fuel that was 20 times more efficient than Hydrogen be useless in space?
Solar panels are improving, but you need to look at the total energy balance. Don't forget about the embedded energy used in making a solar panel, and that you can easily have 100-1000x the surface area growing vegetation than you would have covered by solar panels. They're complementary technologies, each with their own market. No one technology will replace fossil fuels, but this tech will give Hydrogen a bigger place in the energy market.
Winner must be present at particle detector to receive prize. Winner must claim prize within 1.6×1022 s. Winner is responsible for all costs associated with removing prize from CERN property. CERN is not responsible for damages caused by spontaneous decay of prize. Winner is responsible for removing any decay products from CERN property at their own expense.
During a week in 2008, three undersea cables were cut off of Egypt. At the time (and still) the cuts were attributed to ships dragging anchors -- although the fact that there were three cuts so close in time was, and remains, hard to believe.
So, now we see people intentionally cutting a cable. Hmm.
Maybe these three were moonlighting as ship anchors?
What, he couldn't figure out how to tell people to drink water or eat sugar cubes to get healed on his own?
After the training, he was given a piece of paper to hang on his wall saying that he was really good at getting people to eat sugar pills and drink diluted flavored water. Then people paid him to be told to eat sugar pills and drink diluted flavored water. He has other legitimate skills, and is very good in some of them. I knew him before he got into homeopathy, it was an interesting progression to watch.
A friend of mine who was trained in homeopathic medicine* once tried to tell my wife to take a pill for a problem (don't remember what). She asked what it was, because she has a few allergies. He said don't worry, it's a placebo, and still tried to convince her to take it.
Hopefully these GP's had more effective training than my friend.

Not a good analogy, as AT&T didn't lose their database, just exclusivity of it (i.e. now everyone else also has it). A better meatspace analogy might be if a store employee left open a door to an office, and someone walking by took pictures of next weeks sale items (which stores typically don't want released early) and sent that info to a newspaper. The store has not lost any items, just the info about them.
They're not off the grid. When they need grid power, they'll use it. When/if they generate more than they use, it goes back into the grid. The goal of net zero energy buildings is that over a year they'll put back as much energy as they take.
The structure of the old building may have been in poor shape. It's usually cheaper to refit the building, and they would get more LEED points, so I'm sure they would have if they could. If you're concerned about the energy used for construction, I would first look at the amount of embedded energy in that huge field of solar panels on top of the building. I'm surprised that much is necessary. And coupled with the low slope of the roof, I don't think they'll be very effective when it snows.
I heard once that hospitals will cover patients who don't have insurance by charging other patients (who are insured) for the items used. This case sounds like they were trying to double-dip on the bill. If the insurance companies really wanted to get accurate bills they would reimburse patients for such savings up to their deductible amount, co-pay amount, or some combination of them.
The human* brain accounts for 20% of the energy a person uses, and thus is responsible for 20% of their CO2. I appreciate the tireless efforts of Rep. Orcutt in personally reducing this amount as much as possible, and in trying to extend this benefit to as many of his constituents as he can. It seems he has found a great deal of success in this endeavor.
* probably the same for politicians, couldn't find reference to any study of politicians brains.

Instead of water, this sprinkler cart sprays juvenile insults.
I noticed on that list the H.M.S. Flambeau. Isn't that just asking for trouble? Hope it had a good fire suppression system...
There was also a U.S.S. Flambeau
James Dyson is going to be even more pissed. Freeman Dyson probably will be too. Why is the AC trying to piss off all sorts of Dysons?
He's probably hoping all the Dysons come to see him at the same time and angrily surround him.
He will then claim that he has the only Dyson sphere made out of real Dysons.
Why won't they force the terrorists to repay every penny lost due to the attack?
If they truly believed in their cause, the activists would volunteer to take the place of the animals they set free.
I think the scientists affected by this would agree.
I dunno, I ran Picasa on my pr0n dir, and it gets all the Czech models mixed up all the time.
There's your problem- you're using face recognition. Looks like there's a need for an extension so the recognition software can look further south...
Sigh. If only I could fit my cell phone into my pocket.
You just need the right size pockets.

Holy shit that's a lot of technical problems.

1) Blast the rock into pieces.
2) Slap the pieces until the metal falls out.
3) Profit!

No need to bring a flashlight, they sell them there. Now, their plan is starting to make sense...
More seriously, they will still have sufficient lighting in the stores, if for no other reason than so the security cameras can watch everyone.
By 'they' I mean every store, not just Walgreens.
Trillion.
