  1. Re:Electricity + Water on Crunching the Numbers on a Hydrogen Economy · · Score: 1

    Edison's original plan worked, for the scale of electricity distribution that was around then.

    The economics of power plant construction and operation (construction and operating expenses grew less quickly than plant size. Double the output for less than double the cost) drove us to the current scheme with large, centralized electricity generating plants servicing nearby metropolitan areas.

    Now, the only UPS in the house protects TiVo and the cable box. Its surge suppressors protect the TiVo modem line, the Teevee, the VCR, and the DVD player.

    The result of Clinton's "Failed" policy was that the DPRK's nuclear program was frozen. No plutonium was produced or turned into weapons. Carrot and stick.

    The result of Bush's "Successful" policy was that the DPRK's nuclear program was un-frozen. Enough plutonium was reprocessed for 6 to 10 weapons. More plutonium is being produced.

    Those who claim that Clinton's policy failed or that Bush's policy succeeded are obviously pro communist dictator.

    And Microsoft domintated the software industry by violating the "that doesn't quite work yet" part of rule 1. Windows 1 and 2 clearly were products that didn't quite work yet. Windows NT 3.0 and 3.1 didn't quite work yet.

    Rule #2 could also be stated "follow the trail that someone else blazes". Microsoft is very good at that. Microsoft had plenty of mail servers to copy when it was creating Exchange. They started by implementing other people's computer languages. They purchased a clone of CP/M to sell as DOS. They copied the Macintosh when creating Windows. They copied VisiCalc when making MultiPlan, and MacWrite when making Microsoft Word.

    Rule #3 is good, but it's not at all surprising. What kind of business success would one have shipping a non-functional product, or shipping a functional product and then not refining it?

    Economics holds, as a tentative conculsion, that people react to price signals.

    Observations of human economic interactions back up this conclusion.

    It isn't new techonolgies that will reduce usage of oil when the price goes up, it is the individual's self interest.

    It is much harder to predict the extent to which production will decline. The extent to which the price will rise. The extent to which the rising price of oil slows down overall economic activity, relieving some of the pressure lifting the price of oil. These are all the known unknowns (to borrow from Rumsfeld) that make predicting the exact future very, very hard.

  10. Re:Including "innovation" is dangerous. on Comprehensive Projection of World Oil Exports · · Score: 1

    It's not just crazy talk; it's basic supply and demand. Price is the critical balancing factor.

    Supply and Demand are not fixed numbers; they are functions of price. Curves. At a low price, supply is low and demand is high. At a high price, supply is high and demand is low. Somewhere in the middle, the curves cross. There is a balance.

    The supply curve for oil is moving out, while the demand curve is moving up. The world cannot produce as much oil as it used to at a given price, while the consumers of the world want more oil today (at yesterday's price) than they bought yesterday. So the supply equals demand intersection is going to occur at a higher price. Whether total quantities increase or not depends on the details.

  11. Re:Worrisome? on Comprehensive Projection of World Oil Exports · · Score: 1

    Hubbert predicted when U.S. Oil production would peak. He looked 15 or so years into the future, and reality has accorded to his vision. Technological innovation and the ebb and flow of the global economy did not "totally change the entire equation" at all.

    More recent geologists have done the same thing for oil on a global basis. Their predictions are that peak oil is now. Technological innovation and the ebb and flow of the global economy are unlikely to "totally change the entire equation". Oil will become much more expensive, and fairly quickly. The economy will react to expensive oil by discouraging its use, and increasing the incentives to produce alternatives. Farmers may realize that it just isn't economical to use as much fertilizer and pesticides as they do today. Seed drills instead of plows for planting.

    If I had any spare money, I'd bet it on another Recession in the US before Shrub leaves office. And $100/bbl oil by election day (first Tuesday after the first Monday in November, i.e. week of Nov 2-8), 2008.

    The problem with trying to understand why the Republican leadership in the Bush White House launched the Invasion of Iraq is that they have repudiated their own stated reasons for the war. They said it was a war to disarm Iraq of its nuclear weapons. Then Cheney says that even knowing what we know now -- that Iraq had no nuclear program, no chemical weapons, and no biological weapons, he still would have invaded Iraq. Launched a war in violation of the charter of the U.N.

    That's why it was so important to stop the inspections and start the war in 2003, as the inspectors would have discovered that there were no banned weapons, that Iraq was not violating UN resolutions, that there was no loin-cloth of excuse to cover the naked aggression of the United States.
