Even more important is: where do you get all this hydrogen from?? You have any idea how much you'll need to power even a small town?
Currently, hydrogen is more often than not refined from petrochems pumped out of the ground. OK, so you have more control over how those hydrocarbons are released into the environment - but taht's at best a band-aid, not a fix.
An alternative is to 'crack' hydrogen from (sea)water using electrolosis. But, then, you've to figure out where the electricity comes from. Nuclear? Coal fired? Hydro? Solar? (not photovoltac - tiz to laugh Ha! Ha! Maybe heat driven turbine using a recirculated 'media', say - CO2? )
Hydrogen, at best, is an alternative energy distribution system - not an energy source. At that, the distro system is merely 'proof of concept' or speculative. It dosen't exist, yet.
You come up with a non-polluting energy source (like cold fusion, if it worked) and you've got something news worthy. Until then - all this stuff is simple re-hash of exisiting energy stores. And those stores are mostly fossil fueled. 'Neato' - but not life changing.
In context of this story - where do you get the methane from? Pipe barn gas to a power plant? Yea - right! Maybe build a methane powered hydrogen cracking plant at each farm, then truck that hydrogen to a power plant (someone else do the energy density study - I'm working). At least initialy and until a suitable infrastructure is in place, you'll be buying methane made from gooey stuff pumped out of the ground.
Dunno 'bout the others - but Xastir dosen't do route plotting - yet. It's 'on the list'.
However, in the meantime, it does have 'address lookup' - plug in your target addy and it'll show you where it is. From there - look at the maps to see how to get there. Zoom in or out for as much detail or over-view as you need.
Uh, not to start a tiff, but yea - xastir tracks multiple targets/objects too. I show over 12K in my list at the minute.

Us ham types've been doing GPS navigatin not only of our own vehicles, but others as well for over 12 years now! I use a package called 'Xastir' and an on the air protocol called APRS.
Basicly, take a GPS receiver and a laptop (Not just linux, xastir will run on Windows too), a TNC and a VHF radio - use pretty much any map you'd care to use (local or online), current weather information, satallite imagry, NWS alerts, warnings, etc, etc, etc...

1. 25th August 2004: Who knows what tomorrow will bring?
A handful of sites are stating that Eugene Kaspersky, founder of Kaspersky Labs, believes that tomorrow will bring a massive terrorist attack on the Internet. This is being quoted in a range of ways, ranging from factual reporting to citing the story as an example of cyber hysteria.
However, Kaspersky is not predicting the end of the Internet tomorrow - or even in the near future. The story stems from brief comments made yesterday at a press conference which was dedicated to cybercrime and the problems of spam.
At this press conference, Kaspersky commented that the possibility of terrorists using the Internet as a tool to attack certain countries was a reality. As an example, he cited the fact that a number of Arabic and Hebrew language websites contained an announcement of an 'electronic jihad' against Israel, to start on 26th August 2004.
In an interview today, Kaspersky stressed that such information was not necessarily trustworthy. 'We don't know who is behind these statements.' He went on to clarify: 'It's not the first time the term 'electronic jihad' has been used. We've seen this before, with the focus being on sending racist emails, and defacing and hacking Israeli web sites. But it is the first time I have seen sites encouraging the use of Internet attacks against one country as a form of terrorism.'
'As we've already stated many times in the past, it would be easy enough to use a network of infected computers to launch such an attack. We saw the impact that Sasser, Mydoom and Slammer had, on the Internet, businesses and organisations. Just imagine if such an attack was directed at one country or one critical point in the infrastructure of the Internet. Computers are a tool - and just like any tool, they can be used or misused.'
Kaspersky emphasised that the likelihood of a massive attack directed against Israeli institutions tomorrow is low. However, he believes that Pandora's box has now been opened. Hackers and virus writers can be motivated by a range of factors: money, curiosity, or political conviction. But whatever their motivation, the insecure nature of the Internet and weak security precautions offer a wealth of opportunities. 'Maybe it won't be tomorrow, or the day after tomorrow - but sooner or later, terrorists will be using the Internet as another weapon in their arsenal.':snipped::

Just installed Sunbird plug-in to my mozilla 1.7.2 on XP. In Mozilla, I go to window in the menu bar and I can click on Navigator, Email, etc. There're also 'short cut keys' listed in that menu.
From the SANS inst - a PDF file giving step by step, detailed instructions (suitable for newbies!) on how to setup a brand new, un-patched XP box, connect to the I-net, get it all patched and updated *WITHOU* getting it all FUBAR'd in the process.
Good read and should be a mandatory inclusion with every Smith's Club, Wally-World, Shack de Radio, Dell, HP/Compaq, ET-ware, Gamer's Hack Shack or any other end user PC appliance sold.
So, the idea is going here is preparing you for a career, right?
What's the most common thing said about folks right out of school? They can't find their own butt with both hands in the dark!
This 'monoculture' may be a contributing factor, but I think the implied apathy of the student body has more to do with it. At the least, in this case.
Find out what's going on 'out there' in the real world, in your choosen career arena and insist that the training (I assume) you're paying for is pertinant!!
Can you imagine what a resume nugget that'd be?? "Spearheaded the conversion of (school name here) from outdated windows only training tools to current technology (open source even??)". It's an opportunity boy - gonna use it?
Same kinda pseudo geek that'd think Fractena has any cred, let alone is cool.
Google up Nathan Kohen, fractena and rec.radio.antenna (rec.radio.amateur.antenna?? I forget which one, been awhile) - this guy's snake oil has been lambasted so bad it's impressive he's still in busininess!
Crank up the gain, your antenna becomes more and more dipole- it broadcasts very well onto one plane but not anywhere else with a strong signal.
Uh, I do believe you meant to say "directional" there, and not "dipole".
Dipole is a fairly simple and commonly used type of antenna. Roughly: two resonant lengths working 'against' each other, hence the name, "two poles" The word 'dipole' is not normally used to describe a radiation pattern. Dipoles are genreally considered 'omni-directional' radiators.
And you are correct, gain antennas can not 'create' or 'amplify' energy (for that, you'd need an amplifier, duh), they only take what energy is fed into them and direct it in a prefered direction at the expense of other directions. Consider the common yagi (or Yagi-Uda for the purists). Great gain forward, almost none to the sides, limited to the rear.
This cardboard reflector is doing about the same idea - but by reflection rather than refraction. One possible caveat - depending on the distances from radiator to reflector, you can get phase problems. Get the spacing wrong and you can all but cancel out your own signal - or make it unusuable.
You may well want to go take a search through the usenet archives - search on such thigns as "Nathan Cohen" and/or "Fractenna" - see what the guys that've been building, using and exploring antenna design for the past 30 to 50 some odd years have to say about the topic.
Even though one of the most prolific groups dealing with Fractal Antenna designs has been rec.radio.amateur.antenna, most of these guys are long time professionals in antennas: theory, design, testing, building and most importantly, measuring performance. Don't let that 'amateur' fool you. Has to do with ham radio, not their lack of training, skill or expertise on the subject.
At the least - it should answer your question as to 'where are the antennas?'.
Used to have a great deal going with one of the better dentist in town - before I moved away. I did all his office and home PC support - he did all my family's dental care, Me, my Wife and Son.
One night he calls up about 11:00 with a problem with his son's English term paper asking if I could come over next day after work. "When's his paper due?" I ask - "tomarow morning" was the reply. I was there in about 15 minutes, recovered the document and was proclaimed the 'hero' by his teary eyed high-schooler.
His comment? "I don't even respond that fast to dental emergencies!"
Interesting workaround in that I had to do just the opposite. Note, this is *not* a dual boot system. FC only. Earlier used w/FC1 2.4 kern, worked just fine w/LBA enabled in BIOS. Wiped system clean for a fresh FC2 install. FC2 install performed w/LBA on, install completes just fine. But - on boot up, only get to a GRUB shell and pukes. Using GRUB's geometry command, discover that the BIOS geometry values have been changed to something that makes no sense at all for the drive. Re-auto detect the drives in BIOS and save, but on re-boot - same thing again.
Re-installed again - futile - same results. Rather than a 3rd install, I stumbled across just choosing an option without LBA in BIOS after re-autodetecting the drive's and voila. Same install boots up just fine now - been running fine since Tuesday. Simply choosing "2" instead of the offered default "1" for geometry ooptions in the IDE autodetect in BIOS was enough to get things going. Options 2 and 3 don't use LBA in this case.

Not a true geek run'n their server if he can't find the spell check. Seems NASA has lost a lot of it's geekishness overall.
"We are sorry but the slashdoting..."
*^ slashdotting
Yea, it's a slow day here too....
No, their new tech requires changes to the OS they couldn't impliment in Windows - cuz they "don't own Windows".
Wow, the eptiome of techno-lazy. Not only did the OP post a question w/o RTFA, but I replied and gave the info a simple RoTFA would've provided.
Well done

Don't confuse "The National Enquirer" with "The Inquirer". Two totally different publications with pretty much nothing in common.
Mmm, didn't know that - The Inquirer and The Register were started by the same guy...
That's cuz it was later shown to all be a hoax.

Google is your friend.
Lemme get this straight - you're saying transmission lines loose %40 to %60 of their energy in transmitting electricity.
So, how does having more, smaller power plants decrease this percentage?
Problem is in the transmission lines - not the power plants. Review your Ohm's Law for the basics.
Who else wants superconductors at ambient temps?
Dude, you need to get outside more often.
"Torch" is a common term folks in the rest of the world use for what we North Americaners call a flash light.
