fuel cells are being postulated becuase the energy density of hydrogen is magnitutes better than even LiH batteries, let alone lead acid ones.
Fuel cells take H2 and O2, combine them through a catalyst, and generate electricity and water (actually, 2 H2 + O2 -> 2 H2O + electricity). Basic high school chemistry, check it out.
Electrolysis takes water, runs electricity through it, and generates H2 and O2. More basic chemistry.
So, the incremental cost for a fuel cell car to be able to take household 120V and reconvert the water from the fuel cell back to H2 and O2 is pretty small, and it elimates the problem of where to get H2.
GM's fuel cell cars are just a bandaid on the wound of excessive energy consumption caused by private vehicles. Even if they can be recharged overnight by electrolysis, that just moves pollution from the tailpipe to the smokestack, you are still moving over a ton of material to move one person.
Motorcycles really aren't a solution, as they suck in bad weather and too many riders are just potential organ donors. Plus, the newest super bikes have worse gas mileage than an entry level Honda.
We need to swallow our American pride and look after our European betters. We need to change zoning laws to prevent suburban sprawl, while implementing light rail and mini-bus transportation to give everyone about the same commute time as now, but with a less polluting mass transit system. In fact, intelligently applied, commuting times might be less, as traffic density would be a lot less. The next time you're stuck in a traffic jam, think how much more productive you could be in a mini-bus with wi-fi, giving you full internet access on your Linux webpad, instead of stuck behing the wheel.
As a side benefit, we would greatly decrease our reliance on imported oil, and could tell all those towelhead in the mideast to suck sand. Japan's economy would certainly suffer, but they didn't have any qualms about destroying our electronic and automobile industry.
Now, there will be the predictable outcry from the exurbs and rural sorts, but I think private vehicles owned by rural collectives, much like the famed kibbutz of Israel or the efficient collective farms of the Soviet Union would fill the bill neatly.
These flash programmers are making waves by dicking around with flash toolkits, oh boy, how scary! Now, all sorts of other, white, well educated, middle class techies will see them too, oh boy, what a highly charged political situation!
If you want to really make a political statement, start conducting voting drives in lower class minority neighborhoods, nothing like getting the disenfranchised to vote to really bother the man. On the plus side, with the fact that there are more black men in prison than in college, even a fat, pasty faced geekboy has a good chance of finding an unattached woman.
everytime we tried to get into a heavy discussion on ipv6, or Win XP, these barely dressed women would walk by, dance around a pole, and try to sit on our laps. You didn't miss much.
Oh yeah, Asia is just full of gentle, earth loving Asians, who would never dare fill their oceans with mercury, run unstable nuclear reactors, deforest thier jungles, wipe out their tigers, rape their nankings and generally behave just as boorishly as any westerner. Cut the racist crap Timothy, that attitude was old when Kipling used it.
Big deal, so playing sports in zero-gravity is going to be hard. Just how many astronauts are going to be interested in sports anyhow?
I'm sure most of you, like me, consider ball games and other sports the opiate of Joe Sixpack, something to keep his tiny monkey brain diverted from the shallow pain of his useless existence, something to talk about with the other Joe Sixpacks during breaks from the assembly line, but totally useless in expanding knowledge and conquering space. Come on, this is slashdot, lets talk about physics and orbital mechanics, and leave the sporty stuff for stupider, more physically fit sorts.
Unless of course, Rob and company are trying to broaden the/. fanbase by cheapening the discourse to bring in Joe and Jane Sixpack. A word to the wise, don't bother, they only use the 'net to surf for porn.
for fantasy films are never considered serious enough by the academy for people to vote for, all the voters want to show how important and meaningful Hollywood is by choosing the film that's serious and has a meaningful message. So, forgot about a fantasy film, a sci-fi film or a comedy ever getting best picture,it's always going to be a dreary mainstream serious film.
Plus, what person would be so insensitive to vote for the best picture for a film entitled The Two Towers in this post 9-11 age? I hope Peter Jackson shows a little sensitivity and changes the name.
Seriously, this morning it was about 20 F ( -2 C ) with slippery, new fallen snow on the ground. No one was going past 55 on the expressway (normal speed of 65). Living in upstate New York, bicycles are impractical many times a year.
As a kid I rode in winter, but it was dangerous enough that I took old tires and stuffed them with newspapers and embedded nails in them to get a grip. It didn't work.
Otherwise, the world would be facing a unified Europe, ruled by faceless bureaucrats headquartered in a continental European country, and America would be the only country that could go toe to toe with them.
Cut out almost all of the Bilbo, Samwise and Gollum shit. Boring, boring, tramp through the decaying landnear Mordor, boring, boring.
Just give me lots of Eowyn pining after Aragorn, and Merry copping a feel on horseback.

Apple PDA?

They pretty much started the whole market. Most Slashdotters were still in elementary school when Apple started the PDA market, but at least I remember the Newton.

than many new motorcycles, and calling motorcycles fuel efficient is silly today.

Is definitely worth a visit.
I showed up at the Klassy Kat meetup, perhaps I should have tried the Starbucks one.

You can buy basic pieces in bulk from Lego Shop at Home, off the main Lego page. You cna buy some technic parts in bulk from Pitsco-Dacta.

Fortunately, I can take those off your hands, and safely dispose of them, just email me for shipping information.

I'd consider biking it. Instead it's about 15.
My morning commute is about 15 miles.

I was actually using one in 1994, mailing houses apparently bought address lists on 9 track tape.
