I wonder if open source programs are more secure then their microsoft cousins because open source actually helps weed out more bugs or if hacker community just has so much disdain fo microsoft that they concentrate all their energies on M$ products.
I wonder if they come close to solving the storageproblem. Hydrgogen has a low fuel value so you need a lot of it. That means high pressure tanks. Which can be expensive and dangerous.
One thing I know in Syracuse they were working on is storing hydrogen on carbon matrix.
A system similiar to this is already done on the large scale in paper making.
Where CaO is slaked to form CaOH2 in water and used to recaustizice Na2CO3 back to HaOH.
The resulting CaCO3 is recovered and converted back to CaO at the cost of a great deal of energy and time in a unit op called a lime kiln.
There is no way this system can work, assuming the same fuel source you'll using more energy then you gain. And don't eventhink of alternative sources for this one, the reaction requires too muh concentrated energy.
Oops I forgot to balance the equation. And I did sleep through a few lectures.
I don't know if your being sarcastic about your last sentence but i'm not a PhD just working on a masters and in Chem Engineering working on corrosion. You'll find engineers like to take a few shortcuts!
Stainless Steel has chromium in it which forms a chromia layer on it.
The barrier isnt completely airtight it allows oxygen ions to penetrate it but very very slowly. Depending on the metal, corrosion might take place by metal ions diffusing outword.
Electons are transfered through the oxide layer though holes in the oxide structure (much like semi-conductors!)
Also Carbon steel, forms what you know as rust which isnt as protective.
Titanium is actually a higly reactive metal and forms very stable oxides in the Earths crust. It takes a lot of energy to liberate titanium to its mettalic form.
Gold and platinum are very unreactive and are usually already found in their mettalic form, unfortunaely the availibility of these metals is quite less.

Titanium is actually a very reactive metal even more so than Iron.
Fe = -.440 Ti= -1.63
Titaniums corrosion resistance is actually confered to it by the formation of titanium dioxide scales, TiO2 (same stuff in toothpastes go ahead look), the layer slows down the diffusion of oxygen and other oxideizers to the surface of the metal. Much like Chromium does in stainless steel (Cr2O3).
Is Titanium then the best metal for all corrosive environments? Hell no! Its protection is based on the thermodynamic stability of its scales.
Put your nice shiny new Titanium in a highly oxidizing and basic environment (look up Pourbaix diagrams if you want more info). Kiss it goodbye. While plain carbon steel would have resisted it since its scales are stable in that environment and a lot cheaper to. Had you used titanium for your reactor thinking it was the best, you my friend would have been fired.
The moral of the story, there is no one good metal for all applications. You need to consider many factors not to least mention cost.
Waffle house is the gem of ths south. I moved down from NY and just love WH. And in georgia they have one like every couple miles, sorta like the frequency of bagel shops and pizza places back on the island.
For some reason no on else likes the stuff down here. Oh well more cheap waffles for me.
At least now a days it a takes a modicum of sophistication to launch a DoS attack. I remember when it was possible to download windows programs to Win Nuke(win 95 vulnerability) people at will.
What you should have said is that it is exothermic, but even then, the point that it requires a bit of energy is just saying that it needs a little boost to get the reaction going (forgot the exact term for this... its like a spark plug in a combustion engine).
Its called activation energy. And in the presence of some catalyst the activation energy can be lowered but the overall energy change for the system stays the same.
Anyone see that monorail they're building at JFK aiport in NYC. I think its suppose to connect the airport to a redone Jamaca staion. Anyone know anything about it?
It removes all spyware and inserts a fake file which looks like syware so that kazaa can't shut itself down. Kazaa: 'Your stealing my program!" Kazaalite"Stealing is a strong word, we're copy infringing on your program:)"
Then heres the cool thing, edit your "hosts" file. Go ahead search for it. Good you found it. Now any server you don't want to connect to say ads.kazaa.com (just an example.)
type in your hosts file
127.0.0.1 ads.kazaa.com
Everytime kazaa tries to download an add from ads.kazaa.com it'll be looped back to your own computer. No ad!
Of couse kazaa could always just use IP addresses directly bypassing hosts. But they havn't yet.
Another thing, I have no idea whether kazaa lite has this distributed trojan active in it.
No to the empire staebuilding collapsing, I think. First it uses a reenforced heavy concrete, which isnt going to melt like steel. Secondly its built so that there are smaller sections on top of larger sections so the load being supported isnt as much.

If you read the literature fully you'll find that the thermal conductivity is directionally orienented. So if you go 90 degrees in the other direction of the fibers it basically has a thermalconductivity of 1/5 aluminum. (see table 1 of the second ducument).
This may not matter for applictions like a processor, but cooling other objects with more of a 3-d surface may be a problem.
Well, its not just soaking up contaminents.

Phytoremediation
·
· Score: 2, Informative
One of the things that phytoremediation does is soak up metals and organic compound.
It also can have the effect of converting either the metal or organic chemical to a different form.
Say converting lead from its soluble Pb2+. To its reduced mettalic form Pb which isn't as toxic.
Or in organic chemical say PCBs, ploychlorinated biphenols, the plant may break off a few clorines off the phenol chain, again making it less toxic (or at least easier to break down).
So with the correct choice of organisms this should be a safe way of cleaning up things.

For the true ramen experience.
1.Cook your ramen (microwave or stovetop), do not mix in the packet.
2.Drain all water out of ramen.
3.The mix in the packet.
4. eat ramen, with milk nearbye in case your mouth starts to burn
5. enjoy
6. for more flavor use 2 packets per one ramen serving.
Now you might think I'm kidding but i used to eat ramen like this back in the day.
for cereal ramen just eat the ramen uncooked! Use the extra packet for texas style ramen above!!

Sure you'll need a plug in now. But IE 7.x probally won't.

I know this is going to get modded down as off-topic but that Bruce Willis Asteroid flick was one of the worst movies I ever seen.
Except maybe Face-Off with John Revolta.

Palease. Oh another thing Halle Beerry should have lost the academy award the minute she decided to star in operation swordfish with Revolta.
