How reliable have you found this method to be? I've had to occasionally update individual packages, almost always using rpm, and have had no problems, but moving to a new architecture involves an awful lot more -- like new kernels. My dedicated server is about 1500 miles from me, so I imagine you can understand why I'd be wary, even though I'd really like to have the 2.6 kernel active.

    And how do you explain requests to OPEC to further boost productivity, which was to (in theory) lower the price of oil? OPEC is pumping oil at near its maximum capabilities. Part of that is a result of instability, but a larger part of it was the increasing demand for oil in the Asian markets, particularly in China. Beijin even took the step of boosting the oil price internally to slow consumption because the price increases were getting out of hand.

    Life would be a lot happier if oil could get pushed back to around $35 per barrel -- even for Bush.

    The erosion isn't anything I've seen a lot about, but I read some articles a few months ago looking at potential problems with tidal generators placed relatively close to the beaches interfering with wave patterns and in doing so keeping currents in smaller channels, which would force more energy against the beaches and cause additional erosion.

    I'm all for cutting back on power use. At best, though, we would be able to cut energy use by 20% by a massive campaign to replace old refrigerators and light bulbs. I recently went through and replaced all of the bulbs in my house with fluorescents, and my fridge is a little more than a year old, but the main consumers of electricity in my house are the computers. Even though we turn off the monitors and speakers, the systems themselves are drawing a lot of energy on their own. I have a more efficient power supply now than I used to, and my girlfriend is buying a new case for hers, but there's really not much more that we can do with the existing architecture. I have almost talked my mom into buying a new solar unit for her house with her upcoming refinancing, so that will also help, but these steps only go so far.

    Electrical use is only going to increase around the world, and the best way to avoid the problems associated with pollution are through nuclear means. There are some cleanup methods available that minimize the amount of highly radioactive wastes, though some policy changes are required to implement them. At some point, maybe fusion will become viable, but for now, I just don't see any other reasonable means. Our opinions seem to differ on this, but I think faster action on implementing nuclear power is better than trying to twist arms.

    So you'd rather go with the emissions from gas, coal, and oil plants, the ecological degradation of hydroelectric construction and coal mining, the political bickering from oil, the erosion issues from tidal plants, and the chemical morass from solar and battery production all to avoid something that is a rare occurence?

    Simple fact: Universal solar/wind/hydro/tidal is NOT going to happen anytime soon. We don't have the space or the drive for it. Nuclear is hard to push through, but it is FAR easier to do than trying to force reusable energy (which has its own issues) on the world. Nuclear fuel in fission reactions has an energy content of about 2x10^9 kWh/ton of fuel. In less than 2000 tons of fuel, the annual national electricity requirements could be met. Compare this to more than one billion tons of coal being used each year. Moreover, the nuclear fuel could be rebred into useful fuel again, whereas the coal is simply gone once it's been used.

    We have the chance to drop emissions to a fraction of their current amounts, but FUD reactions such as yours -- which are all too common -- leave us on our current path.

  8. Re:Power? on Could Nuclear Power Wean the U.S. From Oil? · · Score: 4, Informative

    Yes, it does, but let's see what led up to the explosion.

    The Chernobyl reactor was poorly-designed. Any reasonable reactor designer would have been able to say as much: the design allowed each and every one of the safety mechanisms to be disabled at the same time. Worse, construction was shoddy at best: parts were often misaligned by several degrees, and when they needed more concrete but didn't have enough cement, they just added more sand, weakening the resulting mix. It was a disaster waiting to happen.

    The #4 reactor was to be shut down for an experiment to determine what would happen in the event of a blackout. The reactor relied on power from other plants to maintain its basic functionality -- office lights, computers, and the cooling systems for the reactors. The reactors fed their own power off to the grid, and other plants were similarly dependent on Chernobyl for their basic functionality. Because of this dependence and the concern for how long they would have before a possible serious failure may occur, they wanted to see how long the inertia of the spinning turbine blades, combined with residual heat from the reactor, would continue to generate power. They thought that perhaps they might gain a little extra time to react in case all power from the grid was somehow lost.

    The experiment was apparently the idea of the plant manager, who had never run a nuclear plant before (being an expert in turbines). His chief assistant had come from conventional power plants. Only a couple of high-level assistants had ever had any experience with nuclear power, and then only with small reactors. No approval for the experiment was ever recieved, but they went ahead with it anyway.

    On the afternoon of April 26, 1986, the reactor output was lowered to about half of normal output, one turbogenerator was brought offline (the remaining one was to be used for the test), and the emergency core cooling system -- the automatic system that moderates the reaction in a critical situation -- was disconnected. A request soon came in to postpone the experiment until late night so that electricity demand would be lower. This was approved.

    At 11pm, the experiment continued. The reactor was brought to its minimum output of 700MW. Above this level, automatic systems keep enough cooling water running through to prevent a runaway reaction. Below it, coolant may not be available in sufficient quantities, and another system will initiate a shutdown. This system was, of course, disconnected.

    The output dropped to 30MW, and radioactive decay began producing excess iodine, which contaminated the fuel rods. This contamination interfered in the chain reaction, making it hard to bring the power back up to acceptable levels. The engineers had to either shut down the reactor or try to bring the power levels back up, and shutting down the reactor would mean that the experiment could not continue, so they tried to power it back up. This meant lifting more of the graphite control rods out to allow the reaction to increase by attempting to "burn off" the iodine contamination. Too many were lifted out -- over the initial protests of one of the engineers -- and the real problems began.

    As technicians increased the flow of water over the rods, the reaction was moderated by the coolant, which meant less steam. Less steam meant less power, which meant more control rods were lifted. More water was also being pumped to prevent buildups in other areas of the system since not as much steam as expected was being generated. The whole system was balanced on a knife-edge.

    Finally, the experiment began. The last safety system, linked to the remaining oeprational turbogenerator and capable of automatic reactor shutdown, was disconnected. Steam to the turbogenerator was blocked, and the turbine began to spin down. With less power, the pumps (already working beyond design capacity) slowed and provided less cooling water to the reactor. Steam, blocked from its normal exit path, built up,

  9. Re:The Bush Factor on Could Nuclear Power Wean the U.S. From Oil? · · Score: 1

    Nuclear is expensive partially because of the costs involved before a shovel is ever plunged into the ground. Westinghouse has a 600MW design called the AP600 (the first design approved by the NRC in years) that is meant to be a universal design, with subtantially the same parts and methods used throughout.

    Unfortunately, the cost of producing electricity with the AP600 (4.1 cents per kilowatt-hour compared to about 3 cents/kWh for other methods) was deemed too high, so they're working on the AP1000, which is basically just a scaled-up version but has a target cost range of about 3.0-3.5 cents/kWh. It's hoped that by designing it so that parts can be made universal for many reactors instead of customized for one site, overall costs will be lower, especially after the first few have been built.

    Is it likely? No, it's not. But it's also not entirely outside of the realm of possibility. Most of those states are heavily industrialized, and by appealing to them -- perhaps in the midst of a major economic downturn led by manufacturing, something people on both sides of the aisle fear will happen -- the election could be won by someone of whom the overwhelming majority of voters do not approve.

    Right now, there are 51 electoral regions (fifty states plus DC).

Each and every region's preference would have a choice, providing a greater chance for smaller states to have an influence, because if a candidate can no longer count on California's 55 votes but instead only has, say, 38 of those votes locked up, then picking up a few more in Nevada or Minnesota might suddenly become more important.

    Better to keep the system, for now at least, and award electoral votes based on the method used by Maine: whoever wins the popular vote gets the two EV's from the Senate presence, and then one EV goes to the person who wins each precint. This makes politicians more accountable to states like California (usually a Democratic stronghold) and Texas (usually a Republican stronghold) that are often ignored in the presidential races.
