"running water into a large pipe and getting smaller makes pressure enough to turn things." This is incorrect. I regularly teach irrigation-related hydraulics classes to professionals in many fields, and this is one of the most common misconceptions about hydraulics. Decreasing pipe size increases velocity, not pressure. Increased velocity in pipes is usually associated with friction loss, or loss of water pressure. Water pressure is only created by the weight of water (with minimal additions from atmospheric pressure) or by mechanical means (pumps). Increasing the velocity may be beneficial in certain situations, but in this case I would convert the low pressure, low velocity energy from the river to electricity by using gears, pulleys and other mechanical aids. The river has plenty of mass to drive a large water wheel which would, with a high reduction ratio, turn a small shaft on a generator at the speeds needed to generate electricty.
OK, i'll bite on this uninformed flamebait. First point - ad hominem attacks are among the weakest arguments you can make. Accusing Darl of being a Scientologist, Chicken Lover, or a (gasp!) many-wived, behorned mormom all fall under the ad hominem label. Second point - generalities are often specifically wrong. Labeling all mormons as twisted, irrational sheep following the voices in their collective heads, and for that matter, labeling all Scientoligists in the same way, is a gross manipulation of the truth. Many people demonize followers of Islam, Catholic priests, Voodoo priests, homosexuals who want to get married, (insert least favorite group here), etc. because of the actions of individuals that to belong to a particular group. Calling someone a "fat, slovenly, pasty-faced, Cowboy Neal choosing, caffine addicted, bleary-eyed excuse for a million monkeys typing on a a million typewriters slashdot poster." may be funny, but it is not necesarily true. Third point - what similarities? Enumerate them, citing official sources. Don't make blanket accusations without specific, verifiable claims. Fourth Point - Insightful in what way? I know am raging against the Slashdot machine, but what was insightful about that post? Darl is a moron, oops, I mearn mormon? Every single article about SCO posted on Slashdot has the obligitory "Darl is a mormon - they are soooo freaky weird" post. We know already! no new insight has beed added to my dwindling pool of knowledge. Please stop, I beg of you, please stop ignoring logic, reason and rational thought. Fifth Point - Many mormons disagree with Darl. I am one who does not agree with him at all. I know many others who dislike his attitude. Mormons can have different opinions about various issues. Darl has his, and I have mine.

What do you mean, $250 seems steep? The 32MB memory stick pro alone is worth the price tag. I'll take two!
