Hydrogen makes no sense as a fuel EXACTLY because it takes more energy for us to produce it RIGHT NOW, than it gives us back RIGHT NOW. Oil takes more energy to produce than it gives off also, but that's unimportant, because the energy input was from the sun millions of years ago, but we can get the output NOW, with far less energy than we have to put in NOW. The same goes for wood, even though its sun energy is put in more or less contemporaneously with our use of it (ie, the sun puts in energy over the course of sometime during the last 100 years, we burn wood and get that energy back NOW). Its called EROEI -- Energy Returned On Energy Invested .... Invested, not Input -- if it were INPUT, all fuels would have EROEI's of less than 1. As it turns out, using current techniques and technologies, EROEI for hydrogen is FAR LESS than 1, while oil is probably more like in the range of 30 to 100 (depending mainly on the grade of oil, depth, and extraction method). Now, in terms of EROEI, there are several things that have greater-than-one values that are NOT fuels, such as windmills and solar panels and wave generators -- we can make these on a relatively "cheap" energy budget, then use them to HARVEST energy that WE (humans) don't have to invest ... because it comes from the sun, or from gravitational forces, in the case of wave energy. The question hydrogen skeptics are asking is, once we have this power generated, why waste a huge portion of it making a fuel, just so Fat Bastards in the fuel-distribution business can keep their jobs? Why not just use the energy directly, instead of shifting it all around into different forms? All THAT said, it does take energy input and materials to make batteries or some other means of storing the energy to propel a vehicle, assuming you want some sort of system where the vehicles don't have to travel along energized tracks of some sort. So the question really becomes, can this (or any tech) make it so the currently-exorbitant-and-unrealistically-huge cost of electrolysis and creation of precious-metal-intensive fuel cells are actually cheaper and more efficient than simply creating batteries and using the generated electricity (almost) directly? And don't even get me STARTED on how impractical hydrogen-as-a-fuel is in terms of STORAGE losses ... Do you think it > costs less to produce batteries than it does to > produce an energy equivalent of Hydrogen? Actually it does ... especially considering the creation of the fuel cell to USE that hydrogen, which nobody's come up with an economical way of making without the extraordinarily rare metal PLATINUM -- the reality is that, without a breakthrough in that area, we CAN'T use hydrogen as a viable fuel, because we DON'T HAVE ENOUGH platinum to create fuel cells for our huge fuel-using infrastructure. All that said, this technique may be useful for > extracting Hydrogen. It needs to be determined if > it takes less energy to do this than other methods of > extracting Hydrogen. At this point, this method could reduce the energy input for electrolyzing hydrogen by an order of magnitude, and creating hydrogen for fuel STILL wouldn't make good engineering sense ...

Radio frequencies breaks apart the hydrogen and oxygen in salt water - watch it burn! http://www.youtube.com/watch?v=4kKtKSEQBeI http://www.youtube.com/watch?v=h6vSxR6UKFM The oil companies are going to be pissed!!! Oh man, I hope this isn't a hoax!

Kernel panic as an unneeded event.
by Oren Beck 11 Sep '07

11 Sep '07

Ok folks, here's a mindset wrench. CAN we make a set of fallbacks to allow a certain minimal function allowing a potential "panic" to seek external help? This help could come from either defaults designed to establish a session with human agents or some AI mimic. Starting from the point I have left us at where it is taken as not arguable that a Knoppix concept routine set CAN establish a remote session and functional remote console interface, then the external intelligence hopefully could complete the Linux install. Constructive comments anyone? Oren Beck "So, you mean there was a time when an installer did NOT include remote support?"

Recommendations for sub-$300 standards-based inkjet printer?
by Leo Mauler 11 Sep '07

11 Sep '07

I just got a nice job with Everest Cable (sadly I do not live in an apartment complex served by Everest) so with the income coming in I will be able to get a replacement printer. The current HP color inkjet printer got knocked off its shelf by some cats, and now only prints in black ink. Someone mentioned that it was a good idea to get a standards-based printer rather than something served by HPLIP. In about three weekly paychecks (temp-to-perm in 90 days) I'll have about $200-$300 to spend on a new printer. I was wondering if anyone has seen a color inkjet printer which is standards-based, for sale at a Kansas City store. ____________________________________________________________________________________ Pinpoint customers who are looking for what you sell. http://searchmarketing.yahoo.com/

"Attempted" Copyright Infringement may be illegal soon.

Proposed Crime of the Century: Attempted Copyright Infringement http://www.wired.com/politics/law/news/2007/05/ippa07 Back in May 2007 Attorney General Alberto Gonzales suggested a new bill that would make "attempted copyright infringement" a crime, punishable by up to life in prison. He would need a sponsor in the House or Senate to make Congress consider it, and I don't know if anyone has agreed to sponsor it yet. This is a really scary law, considering how many currently innocuous activities (such as having a spindle of blank CDs next to your computer) could be made into serious criminal offenses. This is an excerpt from the WIRED article: > Essentially, the bill would turn copyright > law into something more akin to existing drug > laws: The government could seize personal > property, wiretaps would become legal for the > first time, violators could face life in > prison and, in an ambiguous and far-reaching > provision, the mere attempt to violate a > copyright would become a crime. > > The Intellectual Property Protection Act of > 2007, proposed by Gonzales on Monday, would > amend current U.S. copyright law to give the > government far more power to investigate and > prosecute cases, expand the scope of what > constitutes a criminal act, and would stiffen > penalties, including adding life terms for > those whose activities cause death. > > Among the proposed changes, the bill would > make it easier to charge someone as a repeat > offender and stiffen the penalty for > recidivism. It would expand forfeiture > provisions to allow the government to seize > any property used in the commission of a > crime -- a PC, a home, cash on hand. > > Exporting pirated material would also become > a crime and the bill would grant the feds > wiretapping authority, which it currently > lacks. The "attempt" provision, stipulating > that mere intent constitutes a crime, means > that the law could conceivably be expanded > to interpret a computer full of music next > to a spindle of blank CDs as an act of > piracy. ____________________________________________________________________________________ Choose the right car based on your needs.
