You've gotten tons of replies already... I just thought I should say it's nice to hear from someone who's involved with the work that gets reported on this site.
Keep up the good work... And if you find out any more, submit it as a story and scoop everyone.
Sorry. I do have an aunt near Detroit, but she's not a geek.
My relationship advice to all you slashdotters is to look at the girls in your math, science, or CS courses who always seemed to know what was going on and had an interest above and beyond the scope of the course. Geeks need other geeks. Debaters are good, too.
"The physical cause of the loss of _Columbia_ and its crew was a breach in the Thermal Protection System on the leading edge of the left wing, cause by a peice of insulating foam which separated from the left bipod ramp section of the External Tank at 81.7 seconds after launch, and strsuch the wing in the vicinity of the lower half of Reinforced Carbon-Carbon panel number 8...."
Another problem with hydrogen as a fuel was reported earlier this summer. In brief, for you non-article readers, escaped hydrogen will react with oxygen, including ozone, to form water. (Of course, there will be leaks, just as there are oil spills.) Nice, clean reaction, but there's the problem of increasing the "ozone hole".
On a positive note, I suppose this would reduce smog in heavy-traffic areas (as smog is formed as ozone [O3] reacts with nitrogen [N2] to form various nitrogen oxides, including the brown NO2.) However, it'd take a lot of loose hydrogen to competitively inhibit the ozone-nitrogen reaction, and we'd still end up with greater problems than we started with.

Cummon people...
The "-ium" suffix implies an ion... an ammonium ion is NH4+.
"AMMONIA" is NH4.
P.S. Someone tell the/. people they need to enable subscripts and superscripts in HTML.
My personal preference is for Rayovac's reusable alkalines. They've gotten a lot of use in my PDA and my graphing calculator and do quite well. One note on them is that they last longer and hold charge better if you recharge them before they are completely drained, unlike NiCds, which work better if they are completely drained each time.
Using Rayovac's (full size) charger, which claims to charge NiCd, Reusable Alkaline, and NiMH, I haven't had much luck with the NiMH. They seem to get hot and not charge fully. Anyone else see this, or is it just my charger?
Just looked at a few of these...
Story for Argon features an archer, a dragon named "Smaraugh" and an elven queen named "Gloradrial".... Anyone else a little suspicious?
I've got a wonderful little 13-year old toyota with about 127,000 miles. The engine will run at least to 200,000 without any problems. The trouble is that I live in the northern US where snow and salt eat the body of your car. By 100,000 miles, most people (poor college students excluded ) would be embarassed to drive the thing. Right now I'm trying to figure out if I can retard the rust by laminating the entire body in duct tape.
Actually, (I plead ignorance on the efficiencies of the Wankel engine) what would this do to gas mileage, given that the Wankel delivers more power only at higher RPMs than a conventional combustion engine? I realize that a hybrid-Wankel would be more efficient than a car with just the Wankel, but how would it compare to a standard combustion hybrid?
As I see it, the whole thing won't work on a broad scale anyway without a great deal of rather expensive personalization of the drugs.
Because of the redundancies of the genetic code, even highly conserved nucleic acid sequences likely differ significantly between individuals (don't forget also that a single gene mutates on average every million replications, each person has trillions of cells, many of which live a short period, then replicate themselves and their entire genome).
Secondly, cancer cells are highly mutated from their original form, and barely hang on to life as they replicate as fast as they can. They are probably not very representative of the person that they originate in.
The result is that the drugs will likely need to be adapted to work in every patient specifically, will need to be synthesized, purified, possibly isolated from their isomers, etc.... It's not that this isn't feasible, but I don't see it as being able to be effectively provided as of yet.

Fair enough. I misinterpretted your remark. I thought you meant first in the article rather than early in the aftermath of the accident.
I beg to differ on the foam issue.
"The physical cause of the loss of _Columbia_ and its crew was a breach in the Thermal Protection System on the leading edge of the left wing, cause by a peice of insulating foam which separated from the left bipod ramp section of the External Tank at 81.7 seconds after launch, and strsuch the wing in the vicinity of the lower half of Reinforced Carbon-Carbon panel number 8...."
...for anyone to RTFA.
Ok, I'll bite. This summer, I married a long-time slashdotter. #3115, to be precise. Sorry about the redundancy of the sig.
Whoa! Where can I get some of this stuff, and is it safe to be around? (I'm not planning on eating it.)

If anyone's interested, Thinkgeek sells a mod to do this to your existing case, and a case. They're a bit pricey, though.
