Orbiting Lasers for Hydrogen Power

DerekLyons writes: "Yahoo is carrying a story about a Japanese scientist who plans to use giant orbiting lasers to extract H2 from seawater. The interesting part of the scheme is that design uses solar pumped lasers, which avoid the loss of efficiency (and increased launch weight) from powering the laser with electricity from solar cells. Is the way to finally break the main dilemma of the hydrogen economy? (That it takes more energy to make the hydrogen than you gain in using it.)"

Backup Plan (1, Funny)

And if that doesn't work, we can always use the Lasers to take care of spammers.

Why? You don't need to use lasers on shit to extract the methane.

ARE YOU GAY? (-1)

An employee for USAir, who happened to have the last name of GAY, got on a plane recently using one of his company's "Free Flight" programs. However, when Mr. Gay tried to take his seat, he found it being occupied by a paying passenger. So, not to make a fuss, he simply chose another seat.

Unknown to Mr. Gay, another USAir flight at the airport experienced mechanical problems. The passengers of this other flight were being rerouted to various airplanes. A few were put on Mr. Gay's flight and anyone who was holding a "free" ticket was being "bumped".

Airline officials, armed with a list of these "freebee" ticket holders boarded the plane to remove the free ticket holders. Of course, our Mr. Gay was not sitting in his assigned seat as you may remember.

So when the Ticket Agent approached the seat where Mr. Gay was supposed to be sitting, she asked a startled customer "Are you Gay?". The man, shyly nodded that he was, at which point she demanded: "Then you have to get off the plane".

Our Mr. Gay, overhearing what the Ticket Agent had said, tried to clear up the situation: "You've got the wrong man. I'm Gay!". This caused an angry third passenger to yell "Hell, I'm gay too! They can't kick us all off!" Confusion reined as more an more passengers began yelling that USAir had no right to remove gays from their flights.

anyways, this could have numorus benifits for science. I do wonder, communication satellites, using laser transmissions could be smaller, more efficient and easier to deploy. I wonder how much this satellite runs.

IMPORTANT - The Linux Gay Conspiracy (0, Funny)

Anonymous Coward | more than 12 years ago | (#2816035)

It has come to my attention that the entire Linux community is a hotbed of so called 'alternative sexuality,' which includes anything from hedonistic orgies to homosexuality to pedophilia.

What better way of demonstrating this than by looking at the hidden messages contained within the names of some of Linux's most outspoken advocates:

  • Linus Torvalds [microsoft.com] is an anagram of slit anus or VD 'L,' clearly referring to himself by the first initial.
  • Richard M. Stallman [geocities.com] , spokespervert for the Gaysex's Not Unusual 'movement' is an anagram of mans cram thrill ad.
  • Alan Cox [microsoft.com] is barely an anagram of anal cox which is just so filthy and unchristian it unnerves me.

I'm sure that Eric S. Raymond, composer of the satanic homosexual [goatse.cx] propaganda diatribe The Cathedral and the Bizarre, is probably an anagram of something queer, but we don't need to look that far as we know he's always shoving a gun up some poor little boy's rectum. Update: Eric S. Raymond is actually an anagram for secondary rim and cord in my arse. It just goes to show you that he is indeed queer.

Update the Second: It is also documented that Evil Sicko Gaymond is responsible for a nauseating piece of code called Fetchmail [microsoft.com] , which is obviously sinister sodomite slang for 'Felch Male' -- a disgusting practise. For those not in the know, 'felching' is the act performed by two perverts wherein one sucks their own post-coital ejaculate out of the other's rectum. In fact, it appears that the dirty Linux faggots set out to undermine the good Republican institution of e-mail, turning it into 'e-male.'

As far as Richard 'Master' Stallman goes, that filthy fudge-packer was actually quoted [salon.com] on leftist commie propaganda site Salon.com as saying the following: 'I've been resistant to the pressure to conform in any circumstance,' he says. 'It's about being able to question conventional wisdom,' he asserts. 'I believe in love, but not monogamy,' he says plainly.

And this isn't a made up troll bullshit either! He actually stated this tripe, which makes it obvious that he is trying to politely say that he's a flaming homo [comp-u-geek.net] slut [rotten.com] !

Speaking about 'flaming,' who better to point out as a filthy chutney ferret than Slashdot's very own self-confessed pederast Jon Katz. Although an obvious deviant anagram cannot be found from his name, he has already confessed, nay boasted of the homosexual [goatse.cx] perversion of corrupting the innocence of young children [slashdot.org] . To quote from the article linked:

'I've got a rare kidney disease,' I told her. 'I have to go to the bathroom a lot. You can come with me if you want, but it takes a while. Is that okay with you? Do you want a note from my doctor?'

Is this why you were touching your penis [rotten.com] in the cinema, Jon? And letting the other boys touch it too?

We should also point out that Jon Katz refers to himself as 'Slashdot's resident Gasbag.' Is there any more doubt? For those fortunate few who aren't aware of the list of homosexual [goatse.cx] terminology found inside the Linux 'Sauce Code,' a 'Gasbag' is a pervert who gains sexual gratification from having a thin straw inserted into his urethra (or to use the common parlance, 'piss-pipe'), then his homosexual [goatse.cx] lover blows firmly down the straw to inflate his scrotum. This is, of course, when he's not busy violating the dignity and copyright of posters to Slashdot by gathering together their postings and publishing them en masse to further his twisted and manipulative journalistic agenda.

Sick, disgusting antichristian perverts, the lot of them.

In addition, many of the Linux distributions (a 'distribution' is the most common way to spread the faggots' wares) are run by faggot groups. The Slackware [redhat.com] distro is named after the 'Slack-wear' fags wear to allow easy access to the anus for sexual purposes. Furthermore, Slackware is a close anagram of claw arse, a reference to the homosexual [goatse.cx] practise of anal fisting. The Mandrake [slackware.com] product is run by a group of French faggot satanists, and is named after the faggot nickname for the vibrator. It was also chosen because it is an anagram for dark amen and ram naked, which is what they do.

Another 'distro,' (abbrieviated as such because it sounds a bit like 'Disco,' which is where homosexuals [goatse.cx] preyed on young boys in the 1970s), is Debian, [mandrake.com] an anagram of in a bed, which could be considered innocent enough (after all, a bed is both where we sleep and pray), until we realise what other names Debian uses to describe their foul wares. 'Woody' is obvious enough, being a term for the erect male penis [rotten.com] , glistening with pre-cum. But far sicker is the phrase 'Frozen Potato' that they use. This filthy term, again found in the secret homosexual [goatse.cx] 'Sauce Code,' refers to the solo homosexual [goatse.cx] practice of defecating into a clear polythene bag, shaping the turd into a crude approximation of the male phallus, then leaving it in the freezer overnight until it becomes solid. The practitioner then proceeds to push the frozen 'potato' up his own rectum, squeezing it in and out until his tight young balls erupt in a screaming orgasm.

And Red Hat [debian.org] is secret homo [comp-u-geek.net] slang for the tip of a penis [rotten.com] that is soaked in blood from a freshly violated underage ringpiece.

The fags have even invented special tools to aid their faggotry! For example, the 'supermount' tool was devised to allow deeper penetration, which is good for fags because it gives more pressure on the prostate gland. 'Automount' is used, on the other hand, because Linux users are all fat and gay, and need to mount each other [comp-u-geek.net] automatically.

The depths of their depravity can be seen in their use of 'mount points.' These are, plainly speaking, the different points of penetration. The main one is obviously /anus, but there are others. Militant fags even say 'there is no /opt mount point' because for these dirty perverts faggotry is not optional but a way of life.

More evidence is in the fact that Linux users say how much they love `man`, even going so far as to say that all new Linux users (who are in fact just innocent heterosexuals indoctrinated by the gay propaganda) should try out `man`. In no other system do users boast of their frequent recourse to a man.

Other areas of the system also show Linux's inherit gayness. For example, people are often told of the 'FAQ,' but how many innocent heterosexual Windows [amiga.com] users know what this actually means. The answer is shocking: Faggot Anal Quest: the voyage of discovery for newly converted fags!

Even the title 'Slashdot [geekizoid.com] ' originally referred to a homosexual [goatse.cx] practice. Slashdot [kuro5hin.org] of course refers to the popular gay practice of blood-letting. The Slashbots, of course are those super-zealous homosexuals [goatse.cx] who take this perversion to its extreme by ripping open their anuses, as seen on the site most popular with Slashdot users, the depraved work of Satan, http://www.eff.org/ [eff.org] .

The editors of Slashdot [slashduh.org] also have homosexual [goatse.cx] names: 'Hemos' is obvious in itself, being one vowel away from 'Homos.' But even more sickening is 'Commander Taco' which sounds a bit like 'Commode in Taco,' filthy gay slang for a pair of spreadeagled buttocks that are caked with excrement [pboy.com] . (The best form of lubrication, they insist.) Sometimes, these 'Taco Commodes' have special 'Salsa Sauce' (blood from a ruptured rectum) and 'Cheese' (rancid flakes of penis [rotten.com] discharge) toppings. And to make it even worse, Slashdot [notslashdot.org] runs on Apache!

The Apache [microsoft.com] server, whose use among fags is as prevalent as AIDS, is named after homosexual [goatse.cx] activity -- as everyone knows, popular faggot band, the Village People, featured an Apache Indian, and it is for him that this gay program is named.

And that's not forgetting the use of patches in the Linux fag world -- patches are used to make the anus accessible for repeated anal sex even after its rupture by a session of fisting.

To summarise: Linux is gay. 'Slash -- Dot' is the graphical description of the space between a young boy's scrotum and anus. And BeOS [apple.com] is for hermaphrodites and disabled 'stumpers.'

FEEDBACK

What worries me is how much you know about what gay people do. I'm scared I actually read this whole thing. I think this post is a good example of the negative effects of Internet usage on people. This person obviously has no social life anymore and had to result to writing something as stupid as this. And actually take the time to do it too. Although... I think it was satire.. blah.. it's early. -- Anonymous Coward, Slashdot

Well, the only reason I know all about this is because I had the misfortune to read the Linux 'Sauce code' once. Although publicised as the computer code needed to get Linux up and running on a computer (and haven't you always been worried about the phrase 'Monolithic Kernel'?), this foul document is actually a detailed and graphic description of every conceivable degrading perversion known to the human race, as well as a few of the major animal species. It has shocked and disturbed me, to the point of needing to shock and disturb the common man to warn them of the impending homo [comp-u-geek.net] -calypse which threatens to engulf our planet.

You must work for the government. Trying to post the most obscene stuff in hopes that slashdot won't be able to continue or something, due to legal woes. If i ever see your ugly face, i'm going to stick my fireplace poker up your ass, after it's nice and hot, to weld shut that nasty gaping hole of yours. -- Anonymous Coward, Slashdot

Doesn't it give you a hard-on to imagine your thick strong poker ramming it's way up my most sacred of sphincters? You're beyond help, my friend, as the only thing you can imagine is the foul penetrative violation of another man. Are you sure you're not Eric Raymond? The government, being populated by limp-wristed liberals, could never stem the sickening tide of homosexual [goatse.cx] child molesting Linux advocacy. Hell, they've given NAMBLA free reign for years!

you really should post this logged in. i wish i could remember jebus's password, cuz i'd give it to you. -- mighty jebus [slashdot.org] , Slashdot

Thank you for your kind words of support. However, this document shall only ever be posted anonymously. This is because the 'Open Sauce' movement is a sham, proposing homoerotic cults of hero worshipping in the name of freedom. I speak for the common man. For any man who prefers the warm, enveloping velvet folds of a woman's vagina [bodysnatchers.co.uk] to the tight puckered ringpiece of a child. These men, being common, decent folk, don't have a say in the political hypocrisy that is Slashdot culture. I am the unknown liberator [hitler.org] .

ROLF LAMO i hate linux FAGGOTS -- Anonymous Coward, Slashdot

We shouldn't hate them, we should pity them for the misguided fools they are... Fanatical Linux zeal-outs need to be herded into camps for re-education and subsequent rehabilitation into normal heterosexual society. This re-education shall be achieved by forcing them to watch repeats of Baywatch until the very mention of Pamela Anderson [rotten.com] causes them to fill their pants with healthy heterosexual jism [zillabunny.com] .

Actually, that's not at all how scrotal inflation works. I understand it involves injecting sterile saline solution into the scrotum. I've never tried this, but you can read how to do it safely in case you're interested. (Before you moderate this down, ask yourself honestly -- who are the real crazies -- people who do scrotal inflation, or people who pay $1000+ for a game console?) -- double_h [slashdot.org] , Slashdot

Well, it just goes to show that even the holy Linux 'sauce code' is riddled with bugs that need fixing. (The irony of Jon Katz not even being able to inflate his scrotum correctly has not been lost on me.) The Linux pervert elite already acknowledge this, with their queer slogan: 'Given enough arms, all rectums are shallow.' And anyway, the PS2 [xbox.com] sucks major cock and isn't worth the money. Intellivision forever!

dude did u used to post on msnbc's nt bulletin board now that u are doing anti-gay posts u also need to start in with anti-black stuff too c u in church -- Anonymous Coward, Slashdot

For one thing, whilst Linux is a cavalcade of queer propaganda masquerading as the future of computing, NT [linux.com] is used by people who think nothing better of encasing their genitals in quick setting plaster then going to see a really dirty porno film, enjoying the restriction enforced onto them. Remember, a wasted arousal is a sin in the eyes of the Catholic church [atheism.org] . Clearly, the only god-fearing Christian operating system in existence is CP/M -- The Christian Program Monitor. All computer users should immediately ask their local pastor to install this fine OS onto their systems. It is the only route to salvation.

Secondly, this message is for every man. Computers know no colour. Not only that, but one of the finest websites in the world is maintained by a Black Man [stilproject.com] . Now fuck off you racist donkey felcher.

And don't forget that slashdot was written in Perl, which is just too close to 'Pearl Necklace' for comfort.... oh wait; that's something all you heterosexuals do.... I can't help but wonder how much faster the trolls could do First-Posts on this site if it were redone in PHP... I could hand-type dynamic HTML pages faster than Perl can do them. -- phee [slashdot.org] , Slashdot

Although there is nothing unholy about the fine heterosexual act of ejaculating between a woman's breasts, squirting one's load up towards her neck and chin area, it should be noted that Perl [python.org] (standing for Pansies Entering Rectums Locally) is also close to 'Pearl Monocle,' 'Pearl Nosering,' and the ubiquitous 'Pearl Enema.'

One scary thing about Perl [sun.com] is that it contains hidden homosexual [goatse.cx] messages. Take the following code: LWP::Simple -- It looks innocuous enough, doesn't it? But look at the line closely: There are two colons next to each other! As Larry 'Balls to the' Wall would openly admit in the Perl Documentation, Perl was designed from the ground up to indoctrinate it's programmers into performing unnatural sexual acts -- having two colons so closely together is clearly a reference to the perverse sickening act of 'colon kissing,' whereby two homosexual [goatse.cx] queers spread their buttocks wide, pressing their filthy torn sphincters together. They then share small round objects like marbles or golfballs by passing them from one rectum to another using muscle contraction alone. This is also referred to in programming 'circles' as 'Parameter Passing.'

And PHP [perl.org] stands for Perverted Homosexual Penetration. Didn't you know?

Thank you for your valuable input on this. I am sure you will be never forgotten. BTW: Did I mention that this could be useful in terraforming Mars? Mars rulaa. -- Eimernase [slashdot.org] , Slashdot

Well, I don't know about terraforming Mars, but I do know that homosexual [goatse.cx] Linux Advocates have been probing Uranus for years.

That's inspiring. Keep up the good work, AC. May God in his wisdom grant you the strength to bring the plain honest truth to this community, and make it pure again. Yours, Cerberus. -- Anonymous Coward, Slashdot

*sniff* That brings a tear to my eye. Thank you once more for your kind support. I have taken faith in the knowledge that I am doing the Good Lord [atheism.org] 's work, but it is encouraging to know that I am helping out the common man here.

However, I should be cautious about revealing your name 'Cerberus' on such a filthy den of depravity as Slashdot. It is a well known fact that the 'Kerberos' documentation from Microsoft is a detailed manual describing, in intimate, exacting detail, how to sexually penetrate a variety of unwilling canine animals; be they domesticated, wild, or mythical. Slashdot posters have taken great pleasure in illegally spreading this documentation far and wide, treating it as an 'extension' to the Linux 'Sauce Code,' for the sake of 'interoperability.' (The slang term they use for nonconsensual intercourse -- their favourite kind.)

In fact, sick twisted Linux deviants are known to have LAN parties, (Love of Anal Naughtiness, needless to say.), wherein they entice a stray dog, known as the 'Samba Mount,' into their homes. Up to four of these filth-sodden blasphemers against nature take turns to plunge their erect, throbbing, uncircumcised members, conkers-deep, into the rectum, mouth, and other fleshy orifices of the poor animal. Eventually, the 'Samba Mount' collapses due to 'overload,' and needs to be 'rebooted.' (i.e., kicked out into the street, and left to fend for itself.) Many Linux users boast about their 'uptime' in such situations.

Inspiring stuff! If only all trolls were this quality! -- Anonymous Coward, Slashdot

If only indeed. You can help our brave cause by moderating this message up as often as possible. I recommend '+1, Underrated,' as that will protect your precious Karma in Metamoderation [slashdot.org] . Only then can we break through the glass ceiling of Homosexual Slashdot Culture. Is it any wonder that the new version of Slashcode has been christened 'Bender'???

If we can get just one of these postings up to at least '+1,' then it will be archived forever! Others will learn of our struggle, and join with us in our battle for freedom!

It's pathetic you've spent so much time writing this. -- Anonymous Coward, Slashdot

I am compelled to document the foulness and carnal depravity [catholic.net] that is Linux, in order that we may prepare ourselves for the great holy war that is to follow. It is my solemn duty to peel back the foreskin of ignorance and apply the wire brush of enlightenment.

As with any great open-source project, you need someone asking this question, so I'll do it. When the hell is version 2.0 going to be ready?!?! -- Anonymous Coward, Slashdot

I could make an arrogant, childish comment along the lines of 'Every time someone asks for 2.0, I won't release it for another 24 hours,' but the truth of the matter is that I'm quite nervous of releasing a 'number two,' as I can guarantee some filthy shit-slurping Linux pervert would want to suck it straight out of my anus before I've even had chance to wipe.

I desperately want to suck your monolithic kernel, you sexy hunk, you. -- Anonymous Coward, Slashdot

I sincerely hope you're Natalie Portman [geocities.com] .

Dude, nothing on slashdot larger than 3 paragraphs is worth reading. Try to distill the message, whatever it was, and maybe I'll read it. As it is, I have to much open source software to write to waste even 10 seconds of precious time. 10 seconds is all its gonna take M$ to whoop Linux's ass. Vigilence is the price of Free (as in libre -- from the fine, frou frou French language) Software. Hack on fellow geeks, and remember: Friday is Bouillabaisse day except for heathens who do not believe that Jesus died for their sins. Those godless, oil drench, bearded sexist clowns can pull grits from their pantaloons (another fine, fine French word) and eat that. Anyway, try to keep your message focused and concise. For concision is the soul of derision. Way. -- Anonymous Coward, Slashdot

What the fuck?

I've read your gay conspiracy post version 1.3.0 and I must say I'm impressed. In particular, I appreciate how you have managed to squeeze in a healthy dose of the latent homosexuality you gay-bashing homos [comp-u-geek.net] tend to be full of. Thank you again. -- Anonymous Coward, Slashdot

Well bugger me!

ooooh honey. how insecure are you!!! wann a little massage from deare bruci. love you -- Anonymous Coward, Slashdot

Fuck right off!

IMPORTANT: This message needs to be heard (Not HURD [linux.org] , which is an acronym for 'Huge Unclean Rectal Dilator') across the whole community, so it has been released into the Public Domain [icopyright.com] . You know, that licence that we all had before those homoerotic crypto-fascists came out with the GPL [apple.com] (Gay Penetration License) that is no more than an excuse to see who's got the biggest feces-encrusted [rotten.com] cock. I would have put this up on Freshmeat [adultmember.com] , but that name is known to be a euphemism for the tight rump of a young boy.

Come to think of it, the whole concept of 'Source Control' unnerves me, because it sounds a bit like 'Sauce Control,' which is a description of the homosexual [goatse.cx] practice of holding the base of the cock shaft tightly upon the point of ejaculation, thus causing a build up of semenal fluid that is only released upon entry into an incision made into the base of the receiver's scrotum. And 'Open Sauce' is the act of ejaculating into another mans face or perhaps a biscuit to be shared later. Obviously, 'Closed Sauce' is the only Christian thing to do, as evidenced by the fact that it is what Cathedrals are all about.

The slashdot drinking game (-1, Offtopic)

Anonymous Coward | more than 12 years ago | (#2816053)

The slashdot drinking game.

Requires:

Several friends.
An entire day to waste drunk.
Numerous servings of the alcoholic beverage of your choice.


Often, we see the same things day in and day out on slashdot. Why not use
it as an excuse to get drunk?


Rules:


1.Start around 9am, EST, when it's reasonable to assume hordes of
slashdotters will have gotten to work and begun wasting the day trying to
get first post on their company's fat pipe. (If you can actually drink at
work, post where you work. I'll send my resume)
1a. If you can't get all your friends together for an all day
binge, start at night with the oldest article.


2. Play ends when everyone has passed out, puked, or surrendered. Last one
drinking wins. Play shall be suspended if anyone is rushed to the hospital
for alcohol poisoning.


3.For every article with grevious spelling or grammatical errors on the
front page, drink a shot.


4.For every front page broken link, drink a shot.


5.For every JonKatzBot article, drink two shots.
5a. Read the article.
5b. Drink a shot for every appearance of the phrase "coporate
republic"


6.Drink a shot if the first post on a new article is remotely on topic.
6a. Drink another shot if it gets modded up to +5 funny
6b. Drink Two shots if it gets modded to +5 interesting or
insightful.
6c. If someone has moderator points, and blows them all on modding
the first poster up, then that player need not drink, no matter how unfair
the moderating.


7. Drink a shot for every link to goatse.cx
7a. Drink a shot for every ASCII version of the goatse.cx pic
presented in the comments.


8. Drink half a shot for every comment that mentions either:
a. Natalie Portman
b. Beowulf Clusters


9. Drink a shot for every offtopic comment involving the sexual escapades
of any slashdot staff.

I predict that within 30 minutes, there will be at least two confused posts saying that we should just use solar panels to generate electricity to "crack" the hydrogen from sea water.

I further predict that at least one of these will, after someone posts a brief reply explaining why that's not a workable idea, dissolve into flames.

We should just use solar panels to generate this "electricity" to crack the "hydrogen" from the so-called "sea water". Better yet we should use lasers in space to boil the water and thus drive a turbine. And when we aren't making power we can take out small countries with those lasers. They could even use missle defense funds for this. Thus when we aren't defending ourselves we can make more power.

Oh yeah I forgot to add that any extra power we can stick in a giant capacitor. We'll hook that up to the fence on the north and south border...that will take care of homeland security.

...except that, instead of using electrical conversion followed by electrolysis they will use photocatalysis, as described in this Physics World Article [physicsweb.org] , which talks about the implications of a paper published in Nature.

The jist of it, for the link weary, is that by the use of a cunning contrived semiconductor it is possible to arrange the band-gap to be higher that the reduction potential of H2, which allows the production of H2 from the H+ ions that are always present in water.

Early days yet (efficiency is 0.66%, compared with an break-even of 4%), and lifetimes are unknown at the moment. But using solar panels to generate hydrogen should not be rejected out of hand just because the energetics are unfavourable with one particular type of solar cell.

That's why this will never be implemented (5, Insightful)

Master_Ruthless (89957) | more than 12 years ago | (#2816063)

Any government or corporation that puts anything into orbit that could even potentially be used as a weapon is going to face resistance from the entire world. Even if you went into contortions trying to prove that the tool could never be used for military purposes, the media would get ahold of the term "space lasers" and that would be curtains for the idea.

Re:That's why this will never be implemented (1)

PEdelman (200362) | more than 12 years ago | (#2816193)

But why should they care about resistance from the entire world? The US doesn't when they want to actually put weapons in space.

Anyway, for some reason the word "vapor" kept spooking around in my head reading this article. Maybe it has something to do with hydrogen gas. The again, maybe not.

Don't trust them (2, Interesting)

Ricky Glaze (529365) | more than 12 years ago | (#2816064)

I don't think that it would be wise to let the Japanese have that much power that they can point anywhere. It would take up valuable government resources to monitor the direction the laser is pointed and its use. And what if they decided to just blow a city away, then what? Sounds shady to me.

You're absolutely right! In fact... why do we let them have airplanes? We've established that *those* can do significant damage to a city, so lets go take away those commie bastard's airplanes. Hmmm... I bet they could ram a Toyota into a school and kill children! We'd better take those away.

It's for the children!

Re:Don't trust them (1)

ComaVN (325750) | more than 12 years ago | (#2816134)

The Japanese probably didn't think it was very wise to let the americans have a weapon they could use to blow away an entire city. Stop being so self-centered.

btw, I'd say Japan is one of the few countries I'd trust to use such a device wisely. (Except maybe that they'd use it to blow whales right out of the sea into the Sushi bar)

Don't let them? What? (2, Insightful)

The_Unforgiven (521294) | more than 12 years ago | (#2816148)

"let them"?

When did we become their mommy and daddy?
It's science, and something like this would undoubtabley be monitored and studied world-wide. They can't exactly just sneak around with it, and vaporize L.A.

If we were doing this, you wouldn't want Japan contimplating "letting us".

Denito (196701) | more than 12 years ago | (#2816066)

"Back in the 60's, I developed a weather changing machine which was in essence a sophisticated heat beam which we called a 'laser.' Using these 'lasers' we'd punch a hole in the protective layer around the world which we called the 'ozone' layer. Slowly but surely ultraviolet rays would pour in, increasing the risk for skin cancer, that is...unless the world pays us a hefty ransom?"

Thermodynamics (4, Informative)

Hard_Code (49548) | more than 12 years ago | (#2816069)

"That it takes more energy to make the hydrogen than you gain in using it."

Look, due to the laws of thermodynamics it will ALWAYS take more energy to obtain a resource than to use it. Same applies for oil - once we're out of it, it will be very damn expensive to "make" it. So a lot of these arguments against renewable energy sources are just rubbish. Sure, you don't get as big of an *immediate* payoff, but you get a much steadier, reliable payoff over time. The trick is amortizing the expense of using a certain fuel by using the byproducts in a very efficient way. We waste such vast amounts of energy both in direct use, and in unrecaptured efficiency, that I'm sure any number of energy sources will be totally viable (hydrogen, wind, solar, thermal, hydro, methane). But of course many of these will require social changes that nobody is willing to make. To paraphrase Denis Leary, everybody wants to get themselves a 1967 Cadillac El Dorado convertible, hot pink with whaleskin hub caps and all leather cow interior and big brown baby seal eyes for headlights, drive around in that baby at 115mph getting one mile per gallon, sucking down quarter pounder cheese burgers from McDonald's in the old-fashioned non-biodegradable styrofoam containers and when they're done sucking down those grease ball burgers, wipe their mouths with the American flag and toss the styrofoam container right out the side and there ain't a God damned thing anybody can do about it.

So since his lasers are powered by the sun, you are saying that he is not going to produce enough energy to renew the sun?? Damn, I guess this isn't going to work.

Re:Thermodynamics (2, Interesting)

CSieber (548526) | more than 12 years ago | (#2816207)

Look, thermodynamics isn't the most relevant thing here. We're talking about energy sources and fuel, not energy in general. Obviously we all know that its impossible to truly create energy (dE(universe) = 0).

The point here is fuel, and there are two types of fuel: Efficient and Inefficient. An inefficient fuel is one in which you must spend more energy to obtain and process the fuel into usable energy than you get back when you're done. An efficient fuel is the opposite. You put less energy in than you get out.

Right now, fossil fuels are an excellent example of efficient fuels. We put minimal effort in and get an incredible return. However, once we run out of what the Earth has stored over the last several million years, fossil fuels will become extremely inefficient, so it is to our advantage to find much more plentiful efficient fuels.

If this technology makes hydrogen into a more efficient fuel then we should probably support it, as there is a LOT of hydrogen around. :)

hydrogen economy issues (3, Interesting)

mysticbob (21980) | more than 12 years ago | (#2816079)

two objections to the front-page commentary here:
  1. the issue with adoption of hydrogegn is the entrenched position that fossil-fuels have. it's not that hydrogen is harder to use, it's that there is billions invested in transport, wells, autos, etc, all which would have to change. not to mention the industry mogul's (and current usa administration's) vested interest. in additon, you don't need so many specialized resources to create hydrogen, eh - just some electricity and water - think of the threat that poses to the oil hegemony...
  2. there are always energy costs to creating portable forms of energy, but that's the issue, not that it's more energy-expensive to create hydrogen than to use it. add up the costs in shipping oil around the planet. not cheap. the real benefit is that oil is portable once extracted.

Re:hydrogen economy issues (1, Funny)

As opposed to hydrogen which is nailed to the floor upon extraction...

Solar cell (0)

Anonymous Coward | more than 12 years ago | (#2816080)

Couldn't we use this premise to develop a specialized solar cell that would work with a narrow beam of energy?
It seems easier than attempting to farm large fields of dispered light.

Re:Solar cell (2, Informative)

Sobrique (543255) | more than 12 years ago | (#2816188)

Problem is that solar cells are _really_ inefficient. Well, as I recall they had an efficiency rating of 10-30% or so. Lasers are also pretty inefficient (I think they're about the 10% mark too, but I'm sure someone with the appropriate knowlege can correct me), so you'd be wasting an awful lot of power, not to mention probably melting the solar cell. (10% efficient means that almost 90% of that energy turns into heat on the cell)
Using it to boil water for a steam engine might work. Or just powertrip and kill everyone else using the energy of the world and then you don't have to worry about conservation anymore :)

Re:Solar cell (2, Interesting)

Turing Machine (144300) | more than 12 years ago | (#2816249)

Using it to boil water for a steam engine might work.



Most of the "conventional" space solar power ideas (not this one, of course) are based on that. Big-assed focusing mirror (can be very, very thin and very, very cheap in orbit, since you don't have to worry about it collapsing under its own weight) aimed at a boiler. Steam spins turbines, turbines produce electricity, electricity generates microwaves, microwaves beamed to earth. Way more efficient than photovoltaics.

Of course the envirowhackos are going to throw a clot if this idea ever looks like it might take off.

Solar Lasers suck (5, Interesting)

Anonymous Coward | more than 12 years ago | (#2816090)

All known solid state laser gain substances have fairly narrowband excitation spectrums. This presents a two fold problem: 1) fairly little power is available in that window (the sun is a blackbody raditator) 2) Energy outside of that window tends to just heat the medium and either cause breakdown or unacceptable thermal lensing.

I've built a solar pumped nd:yvo4 laser, but it was a waste: because of those factors I could have extracted more power and probably energy from a solar electric system.

Without some serious new developments in laser substances with ultra broadband pump inputs, this won't work too well.

"Is the way to finally break the main dilemma of the hydrogen economy? (That it takes more energy to make the hydrogen than you gain in using it.)"

Unfortunately in the real world it is impossible to make hydrogen from water that holds more potential energy thany you put in. There are always inefficencies in the conversion process, and this process is likely to lose a lot of the solar energy in transmission through the atmosphere. The thing about hydrogen that people forget is that it is just a store for energy that has to be "charged" as it were by separating it from water, rather than a energy source in itself like traditional fossil fuels. However this hydrogen conversion system is better than most in that the energy source for the conversion process is largely free.

cheese_wallet (88279) | more than 12 years ago | (#2816245)

As 400 other people have pointed out, that person was talking about the hydrogen economy, not any laws of thermodynamics.

With that in mind, I think the author meant "(That it takes more of our generated energy to make the hydrogen than you gain in using it.)"

This idea is a conversion from solar energy to the potential energy of a load of hydrogen. It doesn't really matter that it is very inefficient, and that we are using way more solar power to get the hydrogen than the hydrogen contains itself. It doesn't matter because solar power is abundant, virtually inexhaustible, and our only expense is harnessing it.

Energy Storage Misconception (1, Interesting)

Anonymous Coward | more than 12 years ago | (#2816099)


Is the way to finally break the main dilemma of the hydrogen economy? (That it takes more energy to make the hydrogen than you gain in using it.)

You always use more energy to store than to take out. This includes petroleum and regular agriculture. If you think about it, almost every stored chemical energy from earth comes from the sun. In the case of petroleum, we are just using a little energy to EXTRACT the energy BANKED underneath for years.

The question becomes what is our desired medium for energy storage? Batteries can't store a lot of energy. Hydrogen stores a lot per weight but takes too much space. Hydrocarbon/gasoline/liquid fuel is good mix of high energy density for a given weight and a given space. If the US finally able to provide Hydrogen fueling infrastructure, this solar technology might make a lot of sense.

so what if it takes more energy to make... (1, Interesting)

Anonymous Coward | more than 12 years ago | (#2816100)

...hydrogen than what you get using it?
We're mere miles (precisely, an average of just under 1.01 AU's) from a source of fusion sending out more energy in one hour than our current electricity needs add up to in a billion years.
The problem? The Sun doesn't fit nicely in a portable fuel cell.
Hydrogen, on the other hand, does.
Therefore, if we can use a bunch of solar energy that isn't useful right now, to make a little clean-clean-clean hydrogen power, all the better! The ONLY question is, "If we add up the cost to the environment and the cost of labor and materials required to produce a plant (or in this case, an orbiting laser) that gives us X amount of hydrogen, how does that compare to X amount of hydrogen as seen on Ebay?"

Giant Orbital Lasers. (0)

Anonymous Coward | more than 12 years ago | (#2816109)

And this guy's complaining that supertankers hauling oil is are unsafe?

Hmm..if you have an object shooting a laser at the earth from very far away and you alter its direction even slightly, the target of the laser shifts greatly. What happens when a little piece of rock or space junk hits it and jiggles it a little bit?

I could almost see this if you evacuated all of the islands in the Pacific and then had this facility in the middle of the pacific, but if we're going to move away from oil into other energy sources, couldn't we stick to nuclear power or something? At least those things have a track record and don't blow up (too often).

Let's hope the aiming technology doesn't fail on this one.

And here I was just reading about how Unreal Tournament 2 was going to have a way of firing an orbiting laser at your opponents.

Cool.

Seriously though... (2)

Uttles (324447) | more than 12 years ago | (#2816144)

Would this "laser" sent to earth have destructive powers? I'm guessing yes. Someone who knows about this stuff... what would be similar to this beam of light hitting a target? A hand grenade? A stick of TNT?

There is always a catch... (3, Interesting)

Uttles (324447) | more than 12 years ago | (#2816118)

Preface: I have no idea what I'm talking about, I'm just proposing a theory to provoke thought, that's all.

This whole idea sounds really cool and I'd love to live in a world of hydrogen energy, but I've thought for a long time that alternate energy sources have been developed more extensively than we are allowed to know. The political ties between OPEC, car manufacturers, governments around the world, power plants, etc. seem to me to be so entangling that they could easily, and in my opinion have easily, squashed new ideas for alternate power sources. I've heard of everything from water powered cars to solar panel arrays that are 50 times more effecient than those in use today... yet none of these technologies has been allowed to flourish, and I suspect it has something to do with the trillions of dollars that are hauled in by oil companies and any company associated with them. When you think about it in terms of history, oil is the gold of the modern day. People who have it want to make money off of it, so they want to keep supply down (just enough to get by) and demand up, way up. I have no doubts that the people in the oil industry would do anything and everything to keep it the most valuable substance today, just look at some of the evil that came out of the pursuit of gold.

"NASDA and the Institute for Laser Technology in Tokyo set about joint research development of this system. And it is under application for a patent in cooperation with NASDA, ILT and Mitsubishi Research Institute Inc, which is a private think tank company," Dr. Mori wrote SPACE.com in an email interview.

Now, doesn't it strike you as odd that Mitsubishi has their hands in this? OK so it says "a private think tank company," but really, I think this "private" think tank company named "Mitsubishi" wouldn't resist some "inspiration" by the automotive industry (heavily linked to Big Oil) and somehow sabotage or discredit this research.

Anyway, I'll stop ranting, but I'd like to know if anyone has any facts that go along with what I'm saying or if I've just been reading the Drudge Report [drudgereport.com] too much.

So you know, Mitsubishi is the name of a large number of unrelated Japanese corporations. I believe that at one time (pre WWII) they were all one corp, but were broken up by the Allies as part of the surrender terms (as they were heavily involved in the Japanese War industry).

Despite their previous ties, they are now completely unrelated companies, aside from the same name and the normal cartel dealing which is otherwise common in Japanese industry.

Unlike in the States, big compaines in Japan have a little bit of everything. Mitsubishi [mitsubishi.co.jp] makes cars, trains, ships, aircraft, televisions, stereos, agricultural chemicals, food additives, synthetic rubber, molasses, canned foods, textiles, semiconductors ... the list goes on. Any large project in Japan couldn't avoid being associated with a company that also makes cars.

Enviromental effects ???? (4, Informative)

CDWert (450988) | more than 12 years ago | (#2816125)

Ok Im not a tree hugger, BUT what are the long term effects say on the Ozone of pumping a laser of this magnitude though the atmosphere not to mention ionizing radiation effects while it travels through the air ?

My understanding is it REQUIES VERY HIGH temperatures to Dissacociate water on the order of 3500 degreesf plus (PS Dont ever try to quelch a thermite reaction with water :)

Ok so were using Ti02 as a catalyst, what my question is what about thermal evnviormental pollution, hell in some cases its worse than chemical pollution. Hmm were encountering a greenhouse effect globally lets fire oh say 50 or so 10+ megawat lasers at earth. (Its only one until it works)

If this is going to be succesfull youll see a commercial proliferation of these without regard for saftey, No dont think so , look at the oil companies and their rigs , then consider again when Oil companies see this as the next big thing ?
Hell with all that free hydrogen you could manufacture your own hydrocarbons CHEAP, aka GAS ...

Dave Thomas is dying (-1, Offtopic)

Anonymous Coward | more than 12 years ago | (#2816136)

Netcraft now confirms: Dave Thomas is dying.

Yet another crippling bombshell hit the beleaguered Dave Thomas community when recently IDC confirmed that Dave Thomas accounts for less than a fraction of 1 percent of all servers. Coming on the heels of the latest Netcraft survey which plainly states that Dave Thomas has lost more market share, this news serves to reinforce what we've known all along. Dave Thomas is collapsing in complete disarray, as further exemplified by failing dead last [wendys.com] in the recent Sys Admin comprehensive networking test.

You don't need to be a Kreskin [amdest.com] to predict Dave Thomas's future. The hand writing is on the wall: Dave Thomas faces a bleak future. In fact there won't be any future at all for Dave Thomas because Dave Thomas is dying. Things are looking very bad for Dave Thomas. As many of us are already aware, Dave Thomas continues to lose market share. Red ink flows like a river of blood. Burger King is the most endangered of them all, having lost 93% of its core developers.

Let's keep to the facts and look at the numbers.

McDonalds leader Theo states that there are 7000 users of McDonalds. How many users of Hardees are there? Let's see. The number of McDonalds versus Hardees posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 Hardees users. Subway posts on Usenet are about half of the volume of Hardees posts. Therefore there are about 700 users of Subway. A recent article put Burger King at about 80 percent of the Dave Thomas market. Therefore there are (7000+1400+700)*4 = 36400 Burger King users. This is consistent with the number of Burger King Usenet posts.

Due to the troubles of Burgers, Inc, abysmal sales and so on, Burger King went out of business and was taken over by Burger King, Inc who sell another troubled OS. Now Burger King, Inc is also dead, its corpse turned over to yet another charnel house. All major surveys show that Dave Thomas has steadily declined in market share. Dave Thomas is very sick and its long term survival prospects are very dim. If Dave Thomas is to survive at all it will be among OS hobbyist dabblers. Dave Thomas continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, Dave Thomas is dead.

Fact: Dave Thomas is dead

"The costs should not boggle the mind. Petroleum infrastructure on the Earth will cost about one trillion dollars over the next decade and will be useless for producing energy when the oil runs out," argues SSI's Valentine. "A similar investment in SSPs built of non-terrestrial materials would give us an inexhaustible energy source and open the universe for settlement, too."

Exsqueeze me? First, all that oil infrastructure CAN be adapted to refine other hydrocarbon sources like bio fuels. Second, turning asteroids and lunar rock into lasers is probably going to cost a LOT more than a trillion dollars, and take a few decades. And what is all this "colonizing the galaxy" drivel?

I'm quite interested in radical ideas for H2 creation, and improving efficiency of conversion, and making hydrogen infrastructure work economically. Fusion would be nice, if they'd drop more than lunch money into the pot. But do we need to be focusing on building stuff in orbit to make something to put in the car?

Nice idea (2, Interesting)

Sobrique (543255) | more than 12 years ago | (#2816142)

Not quite correct on using less power to produce hydrogen than you gain consuming it - fundamentally that's against thermodynamics, and a source of infinite energy
Burn hydrogen, use energy produced to make more, sell surplus, repeat.
It is quite an old concept, that of an orbiting solar power plant. The medium for energy transferrence is slightly different, but the idea is the same (I seem to recall the early forms of the idea used microwaves beamed down from orbit. Shudder).
Nothing new and revolutionary, but if they can get it working we have tapped another energy source (yes, I know we already have solar power, but an orbital power station doesn't have the limits on size that a ground based one does.)

Re:Nice idea (2)

Uttles (324447) | more than 12 years ago | (#2816158)

I think you missed the point. The article was saying that less energy is used than is gained by the people actually running the system. The Sun, an infinite power source in respect to the span of a human life, provides the rest of the energy. So in total, yes, more energy is used than is gained, a lot more. But as far as we care, we've gained a lot more than we've used.

I think a good extension of this would be to attach a large enough solar collector to a spacecraft which could convert water into fuel in-flight. It's probqably easier to focus a laser through space anyway... How about a moon orbiting collector that can power a station whose only fuel source is ice?

Re: Power and efficiency... (0)

Anonymous Coward | more than 12 years ago | (#2816219)

It will ALWAYS take more power to split H2 from H2O than you derive from recombining it.

What the Japanese guy is doing is trading in an inefficient process (solar cells) to a much MUCH larger battery, directly using sun light. He's trying to take advantage of a free lunch.

The only problem I have with it is what do you about the "target" area, and how do you capture the H2 Earth-side.

This is right up there with desalination plants. In an ideal world, you'd have a nuclear reactor close to the ocean that ran your desalination plant. Or, if the country in question is one like Saudi Arabia, you use some of that natural gas from the oil fields that gets flared off (wasted energy).

A better idea (1)

Sobrique (543255) | more than 12 years ago | (#2816228)

Instead of using energy from burning hydrogen from the sun, to power a laser, to separate more hydrogen to burn it again, what we _really_ need is a giant space vacuum cleaner, and suck up all the hydrogen from the sun directly.
Far more efficient.

What about a flock of birds (1)

What happens when birds fly under this thing? Wait! We could put one at every KFC and a funnel on the roof...

Cost in Dollars != value (5, Insightful)

klaun (236494) | more than 12 years ago | (#2816239)

One problem when comparing plans like this for producing fuel, to other more traditional fuels is that the cost of crude oil or whatever does not reflect the value of the oil.

That is if we had to reproduce the oil rather than just extracting it from the ground we'd probably find other more "green" methods of energy production much less of an investment.

The fact that something that is renewable cost more than something that is irreplaceable is a pointer to the shortcomings of our economic system, not to problems with solar, wind, or other alternative energy sources.

Someone's gotta say it.. (-1, Offtopic)
