Yes, hydrogen CAN be extracted from some hydrocarbon fuels, butwhile looking around for articles on it, I got the impression it's not much more cost or fuel efficient than plain old electrolysis.
There's this article: http://www.batteriesdigest.com/hydrogen_extract.ht m but I don't think I can trust an article where different sentence fragments were apparently written by people who didn't coordinate well with each other (this is an actual sentence from the above webpage):
"Electrolysis of water, the oldest known way to prepare hydrogen, is not new."
Except for the inefficiency that almost every other post is pointing out, increasing indoor humidity might be useful in winter in addition to conventional heaters which just heat the air without adding moisture, effectively lowering humidity to an uncomfortably low level.
rather a Program Designer or "Software Engineer" (whatever that means, and it's on my resume!). When I see the word 'coder' I think of someone with little experience.
Where an "average coder" might write the original code:
total = 0; for(int i = 1; i < number; i++) { total += i; }
A "good coder" might write:
for(int i = 1, total = 0; i < number; total += i++);
but a "good coder" is not neccesarily a good "software designer" or whatever title one might have, who would step out of the loop, see what the code means, and swap out the iterative solution for an algebraic solution if appropriate.
Someone "fixed" the algebraic solution, but it appears to me it is correct, and it's the iterative solution that must be fixed by replacing

I RTFPDF (funny abbreviation), but I have not seen any details on what was thesolution to, in my opinion, the greatest challenge: the switch.
Since I graduated electrical engineering, there has been great progress in the field of solid-state switches. Yet, I think the losses incurred in such a switch would make this experiment unviable.
Power FET's can switch lots of amperes (my EE prof taught me it's either amperes or A. Amp is the abbreviation for amplifier). Put a half million in parallel and control them with something that can dump maybe five miillion amperes into the gates (the Miller capacitance just makes power FET's that much harder to switch fast - perhaps use common-source configuration instead of the rather common common-drain).
Slightly more practically, there are SCR's that have pulsed current capabilities of over 1,000 A, and it should be possible to paralell them and trigger them all at once (make sure the trigger time delay to each one is the same).
In the hihg-voltage experiments a spark gap is a very good and viable alternative, but here we don't deal so much with high voltage as high currents.
Yes, but there's this electromagnetic thing called a transformer. It might even be the way they do it, discharce a capacitor bank into the high-voltage/low-current end of a large transformer, and have a (let's say) six-inch diameter single turn of copper for the secondary.
As I said, I RTFPDF, but the PDF didn't contain any solid technical data, let alone details.
Then, as they say, designing a 19 million ampere switch is an exercise for the reader.
But seriously, sometimes the actual challenge is to reprouce something without being told how it was done. You may even come up with something better. Just stay well away from such operating machinery, for many reasons involving safety, health and plausible deniability ("I don't know a thing about it, I heard noises and thought I'd come take a closer look").
"Russian astrologist who says NASA has altered her horoscope by crashing a spacecraft into a comet is suing the U.S. space agency for damages of $300 million, local media has reported."
She is now suing God for damages related to His creation of this extra planet.
A bunch of good calculations, I'm sure, but as short as the pulse is, the inductance of the conductor is significant. In fact, the inductance and resistance would surely change as the conductor crushes.
Putting a large electric current through a conductor causes a large magnetic field to form which happens to push inward. Or something like that. See my 'small change' post and go to the Quarter Shrinker page, there's more there on the physics of it.

Don't numerous ISPs throw some free web page space, quite often WITHOUT pop-up ads or such ad-related garbage?
I mean with Comcast and its millions of customers, you get some web page space to hotlink images, etc. Sure, you can't do certain questionable web pages(hacking, porn, etc), but still it is included with the cost of your monthly bill.
Yes, but this doesn't help those whose Net access is a free library terminal and who use yahoo/hotmail or other free webmail for email.
Heck, even AOL has web page space.
Again, if there's malware being sent out on free web page sites, perhaps its time for them to go.
That's up to the people who run those sites to decide whether not to shut them down.
OTOH, if ISP's have a lot of malware problems among their customers and believe it's coming from these sites, they can just block these sites so their customers can't get to them.
I've always been amazed at how hard a spammer will work in order to not work.
It used to be that spammers were both stupid and lazy. Actually, they are still stupid and lazy, but in recent years they've teamed up with not-quite-as-stupid "1334 hax0r'5" to help them with their k1dd1e scr1ptz and other such crap.
Remember when they used to wake up the Shuttle crew with corny music piped in through the radio?
They don't still do that? That's dissapointing.
The Space Shuttle program has turned into a big stupid PUBLICITY TRICK.
The one thing the Shuttle could be used for that would have a great deal of value to humanity, namely, to service Hubble, isn't going to happen.
Servicing the Hubble would definitely be a Good Thing, but I hardly see it THAT strongly.
Actually, you may well be right. The ISS is currently no better than MIR, it's barely being kept alive and will probably take more payload to complete it than NASA has available in the remaining Shuttle flights.
The only Shuttle product more popular than Hubble is the DirecTV/DishTV satelite(s).
Your analogy is awful. You don't learn to drive on the freeway. Math students don't earn as they learn at places like NASA. You go on the freeway after you get your license. You go to work as a mathematician after you get your degree.
HTML students do not have to post their crap while they're learning for the world to see.
I think it's YOUR analogy that can use some work.. Putting up bad websites doesn't hurt anyone (well, it may embarrass the author, but that's about it). The Web might be the best or only way for "colleagues" (classmates) or a teacher to view a student's website (or do you want to encourage the idea of HTML emails? Oh well, it's too late to do anything about that). Think of these millions of bad websites as Community Access TV: You don't have to go there.
If the proliferation of bad/sucky websites were the main online problem, Cyberspace would be a MUCH BETTER place.
The true damage to the Net by millions of incompetents isn't due to them uploading websites. If you want to save the onlilne world, force people to read netiquette, and to recognize and not forward chain letters/urban legends/etc., and perhaps even take and pass a test indicating competeny in these areas, before being allowed to send email, Usenet posts, or post to webforum/bbs sites such as slashdot.
And "Emily Postnews said I should do it" is not an excuse: one should be reasonably able to recognize saecasm when one reads it.
If we could make it a one-way trip, I'm sure that we could get several groups to come up with that kind of money. The passenger doesn't have to be willing, do they?
but given its horrificly large cost its very hard to justify Hubble in terms of bang per buck.
That must be why NASA has released so many (highly processed and beautified, but why not?) pics from Hubble, to keep it in the public's eye and have Congress support it. The news media have to have gone along with this, because there are so many dramatic pics available from Earth-based telescopes, even from amateurs with small aperture (relative to the VLT's and such) scopes.

Excellent qualifications.
