Scientific American used to be a great magazine but like any publishing venture headquartered in New York, it has gradually drifted into liberal never-never-land.
Over the years the magazine has run several lead stories encouraging complete nuclear disarmament. At one point it had O.J. Simpson's attorney explaining why DNA technology would never be accurate. Now it's become a shameless, uncritical cheerleader for a world run on renewable energy.
This month's cover story ( http://www.scientificamerican.com/article.cfm?id=a-path-to-sustainable-energy-by-2030 ), "A Plan for a Sustainable Future: How to get all energy from wind, water and solar power by 2030," is a prime example. Authors Mark Z. Jacobsen and Mark A. Delucchi are respectively, a professor of civil and environmental engineering at Stanford and a research scientist at UC Davis -- which makes you wonder what's going on in academia these days. The article is so full of half-truths, absurd omissions and blue-sky fantasy that it is hard to know where to begin.
The authors premise is this: In order to free ourselves from fossil fuels and nuclear power, the authors postulate, all we need to do over the next 20 years is build the following:
• 490,000 tidal turbines of 1 megawatt apiece (<1 percent of which are now in place).That would make a nice stimulus package, wouldn't it? Let's hope Congress doesn't take this too seriously. Offhand, I would say that if we undertook one-tenth of these tasks over the next twenty years we would be very ambitious. Even then, the authors have had to do a lot of fudging. For example:
• 5,350 geothermal plants of 100 MW (< 2 percent in place).
• 900 hydroelectric dams of 1300 MW (70 percent in place),
• 3,800,000 windmills of 5 MW (1 percent in place).
• 720,000 wave converters (ocean turbines driven by waves rather than the tide), 0.75 MW (< 1 percent in place).
• 1,700,000,000 rooftop solar voltaic systems, 0.003 MW (< 1 percent in place).
• 49,000 solar thermal plants (mirror arrays that heat a fluid), 300 MW (< 1 percent in place).
• 40,000 photovoltaic power plants (sunlight directly into electricity), 300 MW (<1 percent in place).
• 900 hydroelectric dams, 1300 MW, 70 percent in place. There are only 94 dams in the whole world that produce more than 1300 MW, eleven of them in the United States. Even Glen Canyon (1296 MW) does not quite qualify. Around the world there are few dam sites left untamed. Even building 70 more dams of this size – let alone 800 -- is unlikely.
• 3,800,000 windmills, 5 MW, <1 percent in place. The largest windmills now designed generate 3 MW. These are "the length of a football field," as President Obama recently mentioned. A windmill generating 5 MW would probably be the length two football fields and stand 80 stories high. Imagine the landscape covered with 3 million these
• 1.7 billion solar rooftop systems. With only 6 billion people in the world, there may not be enough rooftops to house all these. We'll have to put up some more buildings just to accommodate them.
• 89,000 solar thermal and voltaic plants, 300 MW apiece. It takes about 15 square miles to generate 1000 MW with either system. There is little room for improvement, since the limits are set by the sun's energy. That amounts 450,000 square miles, about the size of Texas and California combined. Solar mirrors and panels must be washed once a week or they collect too much dust and lose their efficiency. That's a lot of water.
Oh well, this isn't really a serious exercise, is it? The authors are just doing some creative thinking so the U.S. delegation at Copenhagen in December can have something to wave in front of the cameras. The lead editorial praises the authors' "hard-headed pragmatism," saying they show "step by step… that more than enough sustainable energy exists [and] the needed technologies are available now."
What is truly remarkable is that the authors' inventory of knowledge seems to include nothing about nuclear power, the one technology that can truly provide "green energy." To begin with, they barely make any distinction between nuclear and fossil fuels, lumping together as the old way of doing things:
Most recently, a 2009 Stanford University study ranked energy systems according to their impacts on global warming, pollution, water supply, land use, wildlife and other concerns. The very best options were wind, solar, geothermal, tidal and hydroelectric power -- all of which are driven by wind, water or sunlight (referred to as WWS). [This statement is incorrect. Geothermal energy is driven by the radioactive heat of the earth due to the breakdown of uranium and thorium. That's why I called my book "Terrestrial Energy."] Nuclear power, coal with carbon capture, and ethanol were all poorer options, as were oil and natural gas.… Nuclear power results in up to 25 times more carbon emissions than wind energy, when reactor construction and uranium refining and transport are considered. Carbon capture and sequestration technology can reduce carbon dioxide emission from coal-fired power plants but will increase air pollutants and will extend all the other deleterious effects of coal mining, transport and processing, because more coal must be burned to power the capture and storage steps. Similarly, we consider only technologies that do not present significant waste disposal or terrorism risks.
Where the authors get the notion that nuclear will emit 25 times as much carbon as wind is anybody's guess. A reactor contains about 500,000 cubic yards of concrete and 120 million pounds of steel. Yet a single 45-story windmill stands on a base of 500 cubic yards of concrete and contains as much metal as 120 automobiles. Since you need 2000 of these to equal one nuclear reactor (a very generous estimate), that adds up to twice as much concrete and steel.
Then there's the business of uranium enrichment. Environmentalists love to argue that nuclear is actually more carbon-intensive because uranium enrichment requires such huge amount of electricity. This is true in one respect. The country's only operating uranium enrichment plant in Paducah, Kentucky requires 2,000 MW of electricity -- supplied by two full-fledged coal plants. But the plant employs World War II gas-diffusion technology. The United States Enrichment Corporation's new laser enrichment plant in Ohio would consume only 5 percent as much electricity- except that the Obama Administration has mysteriously rejected its application for a $2 billion loan guarantee and work has been temporarily suspended. In any case, uranium enrichment produces carbon emissions only if the electricity is supplied by coal. If enrichment were powered by nuclear power, carbon emissions would be zero.
Then there's the business of "transporting uranium fuel." It's hard to tell what the authors are talking about here. A nuclear reactor requires a new shipment of fuel rods once every 18 months. They are delivered by about six tractor trailers. There is probably more energy expended in hauling a single giant windmill to a remote farm location than is spent in refueling an entire 1000-MW reactor.
Where the authors lose all contact with reality, however, is in talking about "reliability." Here is what they have to say:
WWS [wind, water, solar] technologies generally suffer less downtime than traditional sources. The average U.S. coal plant is offline 12.5 percent of the year for scheduled and unscheduled maintenance. Modern wind turbines have a down time of less than 2 percent on land and less than 5 percent at sea. Photovoltaic systems are also at less than 2 percent. Moreover, when an individual wind, solar or save device is down, only a small fraction of production is affected; when a coal, nuclear or natural gas plant goes offline, a large chunk of generation is lost.
Here are the facts. Every form of electrical generation is rated by what is called its "capacity factor," meaning the percentage of time, on average, it is up and running. Plants go on- or off-line for many reasons – maintenance, refueling, high costs, or simple unavailability. Coal plants are generally shut down once every two weeks to perform routine maintenance and "give the boiler a rest." Natural gas is often taken off-line because the fuel is so expensive. Hydroelectric dams shut down because of fish migrations or seasonal variations in reservoir capacity.
The generally accepted capacity factors for the various forms of generation are as follows:
• Nuclear -- >90 percent
• Coal -- ~80 percent
• Geothermal -- 75 percent
• Natural gas -- 50 percent
• Hydroelectricity -- 45 percent
• Wind -- 30 percent
• Solar -- 20 percent
In order to fabricate their argument, the authors have:
1. Considered only maintenance shut-downs and not general availability, and
2. Completely ignored the capacity factor of nuclear.
Windmills may only offline for maintenance 2 percent of the time but the wind only blows about 30 percent of the time. Solar power is available even less. Neither is "dispatchable," as the electrical engineers say, and therefore require constant back-up from other sources. Storage techniques may eventually solve this problem but the storage facilities will take up as much room as the generators themselves.
What Jacobson and Delucchi have managed to leave entirely out of the picture is the concept of energy density. Nuclear power's overwhelming advantage is its tremendous energy yield per pounds of resource employed. A pound of uranium contains 2000 times as much energy as a pound of coal. In real life, this translates into a 110-car coal train arriving every 30 hours versus six tractor trailers arriving once every 18 months.
Yet while nuclear has a tremendous advantage over the fossil fuels, so the fossil fuels have about 20 times the density of wind, water and solar. That is we adopted fossil fuels in the first place. We no longer use the wind to power grist mills or waterwheels to run factories because it takes too much effort to gather too little energy. What renewable enthusiasts are asking us to do is move backwards in history.
Even more significant, the world of Jacobson and Delucchi would be the most colossal human intrusion into the natural world the history of the planet. It would dwarf any previous effort of civilization. We would live in a forest of 80-story windmills interrupted by rolling prairies of solar collectors. Every inch of coastline would be girdled with tidal generators while every square mile of ocean was dotted with wind and wave collectors. There would be no place on the planet not dedicated to gathering energy.
Could we do it? Sure, we probably could, although not on the time scale Jacobsen and Delucchi propose. Would we want to do it? You can answer that question yourself.
...The bill—the highest denomination of all U.S. notes—circulates widely around the world, with circulation in the past 25 years growing to $890 billion from $180 billion.
About two-thirds of all $100 notes circulate outside the U.S...
...The 6.5 billion or so $100 notes in circulation now will remain legal tender...
"Modern agriculture has been described as a way of turning hydrocarbons into food. Without cheap energy— a single gallon of gasoline is the energy equivalent of 100 hours of old-fashioned labor— the world would certainly have trouble producing half of the current food supply, and that fraction could be substantially less. Hydrocarbons are not only critical to farm equipment and food distribution over very large distances, but also play a dominant role in fertilizer production. With sparse hydrocarbon usage, American agriculture would have to be totally and painfully restructured..."
-Jeremy Grantham
It was on this day in 1925 that the poet T.S. Eliot (books by this author) accepted the offer of a job at a small publishing house Faber & Gwyer, which soon changed its name to Faber and Faber. One of the first poets Eliot discovered was the young W.H. Auden, and he went on to publish work by Marianne Moore, Siegfried Sassoon, Jean Cocteau, James Joyce, and Ted Hughes. Under his leadership, the firm passed on publishing Animal Farm by George Orwell, but they chose to publish a book that had been rejected by everybody else in Great Britain, called The Lord of the Flies. It would become the best-selling novel in Faber and Faber's history.
Eliot liked the job in part because he was rarely able to write for more than three hours a day, and he liked having something else to do that made him feel useful. He found it dispiriting that the medical publications continued to outsell the poetry collections. Eliot later said, "With most categories of books you are aiming to make as much money as possible, with poetry you are aiming to lose as little as possible."
...By making booze illegal, the government unwittingly glamorized it. The bubbles in a glass of champagne seemed more scintillating, the foam on a mug of beer more refreshing. Homemade alcohol had a tendency to taste like battery acid, which led to the invention of cocktails; the addition of sweet flavors and herbs made the drinks even more alluring, especially to women. Irving Berlin summed up the state of affairs and put it to a snappy tune when he wrote, "You Can Not Make Your Shimmy Shake on Tea."
Congress passed the Volstead Act to provide for enforcement of the Eighteenth Amendment, and at least in the early years under the new set of laws, alcohol consumption in America dropped dramatically. But the Volstead Act failed to anticipate the massive criminal operations that would go to work creating an underground network for the manufacture and sale of alcohol.
A man didn't have to be a genius to recognize this once-in-a-lifetime opportunity. Overnight, general miscreants such as Capone became bootleggers (the phrase has roots in America's colonial days, probably deriving from "boot-leg," the upper part of a tall boot where bottles could be hidden). Their experience running bars, brothels, and gambling joints suddenly came in handy. They already knew how to move money, how to sell booze, how to subdue competition, and how to service multiple businesses across the city. The trick now was learning to think big. A massive legitimate business had just been declared illicit. If they moved quickly, they could take over operations. Just for starters, bootleggers needed trucks and confederates in other cities to help them with supplies. In New York, there was Meyer Lansky; in Boston— Joe Kennedy; in Philadelphia, Boo Boo Hoff; in Detroit, the Purple Gang; in Cleveland, Moe Dalitz; in Montreal— Samuel Bronfman. They patched together a network that would eventually become a loosely organized national crime syndicate.
As bootleggers, their position in society actually improved. Small-time reprobates no longer had time for safecracking, pickpocketing, and mugging. Those lines of work were too dangerous, too risky, and didn't pay well enough.
Bootlegging also offered a certain kind of dignity. As bootleggers, they provided a useful service and catered to a respectable class of customer. Flush with cash, they dressed with panache and consorted with a higher class of friends. They became romantic figures, celebrated by journalists who liked their style, their slang, and their nicknames—not to mention their booze

Someone else talking out their ass...
Current U.S. government policies are absolutely adverse to retirees and seniors. Let me explain in rather simple terms. Retirees over 65 live off of income from three sources, Social Security, pensions or other retirement plans, and savings. Social Security is in stress through no fault of the current administration. The ultimate solution, which probably won’t happen until a crisis occurs, will be to means test benefits or delay the age when benefits begin. That in itself won’t hurt most seniors today and the ones who earn enough money that they don’t need Social Security probably won’t suffer greatly if benefits are withheld as a result of means testing. So let’s move on and consider the next component, savings. They are mostly invested in cash, money funds, CDs, short term high grade bonds and blue chip stocks. We all know where interest rates are. They are near zero. And they are there for three reasons. The stated reason is to stimulate low cost borrowing but given the steady drop in money supply and decline in new loans, low rates aren’t the necessary catalyst for lending today. The second reason for low rates is to create a steep yield curve that helps to bail out the banks from the mess they got themselves into during the recession. In other words, seniors and those of us who save are earning less so that banks can earn more. Last, while not a direct cause of low rates, note that the Federal government itself benefits greatly paying a tiny fraction on its debt versus what it would be forced to pay in normal times. Do the math. $12 trillion in debt times just 1% is $120 billion. A normal 3% borrowing rate would cost the Federal government $360 billion. Thus, while the fiscal math doesn’t dictate Fed interest rate policy, certainly it isn’t harmful to the Federal budget that interest rates are near zero.
Low rates aren’t the only cause of pain for seniors. Look at what is happening to investments in blue chip stocks. Current tax rates are 15% on capital gains and dividends. Starting January 1, the maximum rates go to 20% for capital gains and 39.6% for dividends. Move forward 3 years and you can tack on another 2.9% courtesy of the new health insurance reform law. In other words, without any changes, taxes on dividends may almost triple in a few years.
Estate taxes are next. They are now zero. Next year they go to 55% and the deductible falls from $3.5 million to just $1 million.
In fairness, the Obama administration earlier this year advocated much lower rates for both dividend and estate taxes but that was before budget deficits ballooned and before the European sovereign debt crisis blew up. While some still insist that tax reform is on the agenda, there has been virtually no movement to date.
Finally IRA withdrawals are taxable at ordinary income rates. The new Roth IRAs seek to deal with that issue but only if one pays taxes up front upon conversion.
An individual without a pension with $500,000 in cash, CDs and stocks stands to make something over $25,000 from Social Security. In normal times, they might earn 3% or more in interest and dividends from their investment portfolio. That could add another $15,000 or 60%. But in today’s environment, a 1% after-tax return on that $500,000 of savings ( or $5,000 ) might be a more logical expectation. $30,000 [ $25,000 plus 1% of $500,000 ] is only 75% of $40,000 [ $25,000 plus 3% of $500,000 ].
The chart of drilling parameters for the last two hours before the blowout suggests that the riser and upper 3,000 ft of the wellbore were fully displaced with seawater by 20:00 on April 20, and the crew was circulating the drilling fluid. Beginning 10 minutes later, at 20:10, the mud pit volume began to increase probably because of gas influx. The volume increased so much, that the recorder re-zeroed four times. When the crew stopped pumping at 21:08, the mud pit volume decreased and this may have alleviated some concern about gas influx.
At 21:30, they stopped pumping again and circulated, but the pit volume continued to increase(Figure 5). Standpipe pressure increased and decreased twice between 21:30 and 21:42 (standpipe pressure generally reflects bottom hole pressure). This, along with a steady increase in mud pit volume, suggests that surges of gas were entering the drilling fluid from a gas column below the wellhead, and outside of the 7-inch production casing. Gas had probably channeled past the inadequate cement job near the bottom of the well and, by now, had reached the seals and pack-offs separating it from the riser at the sea floor.
At 21:47, the rate of standpipe pressure and mud pit volume went off scale, and water flow was measured at the surface. The blowout had begun.
Between 21:47 and 21:49 the gas behind the 7-inch production casing apparently overcame the wellhead seals and pack-offs that separated the wellbore from the riser. Almost instantaneously, the gas shot the water out of the riser and above the crown of the derrick. Then, the gas ignited and exploded.
Should I admire stupid people?
Should I trust the uneducated to make decisions that affect me, when what I am doesn't even ping in the limited world of the conservative dimwits?
By and large, stupid people are attracted to conservatism. It's easy. it does not require thought. You can be proud that you've got exactly what your daddy had. The conservative world is filled with other conservative people, and anyone who can't live in it is the enemy of conservatism, plain and simple. And you know who can't live in a a conservative world? The well-educated. You do have a connection with education. it's a negative one, unfortunately.
By the way-- I have no college degree. None. But I am smarter, and more educated than you are, because it is easy to keep on learning.
But you need to calculate the potential for damage that just one large spill can inflict, as well.
And the damage that just one catastrophically large spill can inflict.
And you might want to calculate what the cost will be in human lives and suffering as a result of that statistically small but realistically inevitable spill will cause.
Actually you have shown quite consistently that you don't want to calculate things like that. I'm sure you consider yourself a compassionate human being. You don't seem to know what compassion actually is, though.
I happened to read... Malthus on Population, and being well prepared to appreciate the struggle for existence which everywhere goes on from long continued observation of... animals and plants, it at once struck me that under these circumstances favorable variations would tend to be preserved and unfavorable ones to be destroyed. The result of this would be the formation of new species.
The state oppresses and the law cheats
The tax bleeds the miserable
No duty is imposed on the rich
'Rights of the poor' is a hollow phrase
Enough languishing in custody
Equality wants other laws:
No rights without obligations, it says,
And as well, no obligations without rights
