An Apology and a New Beginning

Friday, November 18th, 2011

By David L. Brown

If there’s anybody out there I owe you an apology and this update. Much to my embarrassment I have not posted to this personal website for many months. In my defense I will report that my beloved wife Patricia was in failing health and had been diagnosed with cancer. She died on June 21, 2011, first day of Spring. Needless to say, I have been diverted from pleasures such as this personal blog.

On a happier note, I can report that I have made the transition to full-time RV living, as reported on by my cat Tiggy in her regular postings under the heading Travels with Tiggy (see link on the right). Tiggy is also writing a column for the bimonthly newspaper The Bosque Beast, and apparently has made a great hit with readers, some of which are apparently animals such as dogs and other cats.

I am getting myself into a healing mode and plan to begin writing again. I published two books last year, a novel titled Quantum Cowboy, and a non-fiction book titled Dead End Path. Both are available on Amazon either as print or ebooks. I have several other projects that I want to pursue during the coming months, including another non-fiction project and a couple of novel ideas. I will also be making photographs as time goes on, mainly because as both writer and photographer I must actively create in both media.

Tiggy will keep you updated on our travels and I will resume posting my thoughts and ideas here (I promise, Scout’s honor.)

How Hot Is It? This Hot!

Friday, July 16th, 2010

By  David L. Brown

Yesterday I wrote about a new report from NASA, reporting that 2010 is the hottest ever so far. To get a visual image of what that means, here’s a map from the agriculture.com web site showing the predicted high temperatures across the United States for this date, July 16.

An all-red, fiery weather forecast for today

An all-red, fiery weather forecast for today

If you think this may look like an image from Hell, you may be right. Farmers are complaining of too much rain in the Corn Belt, too little in the Southeast. To give you a feel for what some farmers are experiencing, here are excerpts from a few recent comments posted by farmers on the AgWeb.com site (you can read more farmer comments here):

7/13 – Northeast Indiana: Some are still trying to plant beans. Now we can’t buy a rain and not much in the forecast. Even the good corn is firing now, no nitrogen left to finish this crop. With shallow roots, it won’t take long to become real ugly.

7/13 – York Springs, Pa.: Our crop (beans and corn) are about shot…we have not had any rain since mid-June. Corn is 2′ tall, shooting tassel. We are hoping that the Midwest has plenty!

7/13 – Fayette County, Ill.: Finally got finished planting beans for the first time this year in the river bottom on Monday, the 5th of July. Every time I got ready to plant, it rained and stayed too wet. Lots of drowned out or very poor crops in some areas of central Illinois and some good-looking crops in well drained areas.

7/12 – South central Iowa: Our crops are the worst I have seen in all of my travels across the Midwest over this last month. It is the worst corn we have ever grown and we have been completely helpless as it rains and rains.  It is pretty much a lost cause at this point.

7/9 – Coles County, east central Illinois: I walked out into my corn fields to check for gray leaf spots and found something worse: In a field that has looked good, was planted in good conditions on soybean stubble, had 210 lb. NH3 fall applied, was beautiful when I did post spraying, now when you walk in the field about 20′ you find stalks that are dead from the ear down. With all the constant rains, the corn never put down much roots and is not picking up the nitrogen. This is not just in low spots, I am finding it on hills also. It does not look like a bumper crop to me!

7/8 – Shelby County, Tenn.: National Weather Service, Memphis: It’s official, Memphis/mid-South area, June was the second hottest and fifth driest ever!

7/7 – Bucks County, Pa. (sweet corn crop): Very dry, having to pump water to keep crop looking and growing good. Temps 100° plus, pond is 4′ below normal. Working to 11 p.m. keeping sprinklers and pumps running, and there is a real fear of fire due to dry woodlands and grass. With that said, crop looks great. Hope the pond don’t dry up!

7/7 – Sussex County, Del.: Very dry here, temp over 100°. Corn crop burning up, soybeans standing still, not growing at all. Feeding cattle winter hay already. Pasture is gone, one cutting of hay, there won’t be another.

7/6 – Central Pennsylvania: Dry, dry, and dry. Only an inch of rain for the month of June, if that. Corn is curled up, and looks terrible. Only corn that looks good is on ground that holds moisture the best.  If it doesn’t rain soon, well… we won’t need the chopper to come around to process our corn silage for our dairy cows, there won’t be a kernel to process, and not much stalk to chop either.

All-in-all, it’s shaping up as another difficult year for farmers, with Goldilocks conditions of flooding and drought and excessive heat added on top of that. We’ll stay abreast of the situation as we move into the critical late-July and August growing season, when the worst heat stress usually occurs.

Is Climate Denial a Form of Grieving?

Sunday, July 11th, 2010

By David L. Brown

Note: The following is excerpted from a new book I’ve just completed writing. It makes interesting food for thought about the phenomenon of denial.

It may seem hard to understand how so many people can remain in denial about the threats that face us. It probably comes down to psychology, and the natural tendency of individuals to protect themselves from unpleasant facts. Some writers[1] have suggested that refusal to accept the very real possibility our technological civilization is in danger of collapse is due to a process similar to the stages of grief described by Swiss psychiatrist Elisabeth Kübler-Ross.[2] Denial is the first stage in her description of the process of grieving, followed in order by anger, bargaining, depression, and finally acceptance.

We can see that gaining a state of acceptance is not an easy transformation, and who can imagine a greater cause for grief than to mourn our very planet and the injuries humanity has done to Nature?

If Kübler-Ross’s ideas apply to how individuals react to the present state of civilization, those in denial have several stages to go. Others are more advanced. You might profit from deciding where you fit on the scale of “grieving” over the impending changes in our world.

In the stage of denial, the most hard-core resisters often claim the danger of resource depletion is vastly over-stated, that those of us who sound the alarm are nothing but Chicken Littles, conspiracy theorists, or loonies. Their heads are firmly in the sand.

Those in the second stage of anger are looking for someone to blame. Obvious targets (and not without reason) are Big Oil, power companies, foreign countries such as Saudi Arabia or China, globalization, or those ever-popular scapegoats politicians. These might be people you would see waving signs on picket lines.

Those who have reached the stage of bargaining might pin their hopes on an almost cult-like confidence that new technologies will allow us to find and use more resources. Bargainers are always seeking “solutions,” such as escape to space or some unexpected discovery that will make everything safe again, so that “progress” can continue unhindered.

I know many people who tell me they don’t want to think about this subject because it’s depressing. They are in the fourth stage of the process.

I rank myself in the stage of acceptance, and it’s only when that point is reached that one can see clearly enough to apply the powers of reason and analysis to the challenges that face humanity. Rather than being depressed by the study of this subject, I find it of intense interest — although it’s discouraging to see how many are still in the earlier stages of “grief,” particularly that counter-productive state of denial.

Hand-held device to detect infectious pathogens

Tuesday, January 5th, 2010

By David L. Brown

A new high-tech device to detect dangerous pathogens in ordinary medical sttuations is being developed through a partnership between Los Alamos National Laboratory (LANL) and Biomagnetics Diagnostics Corporation (BMCP). Described as “optical biosensors,” the devices are based on technology developed and patented by LANL.

Being battery powered, the hand-held optical detectors will have the advantage of portability. Simple to use, they will allow on-the-spot medical screening without requiring the services of a medical laboratory.  Able to automatically detect the presence of various viral and bacterial pathogens, they can be used by relatively untrained medical personnel. The sensors give a result almost instantly. Think Mr. Spock with a TriCorder here.

The original concept was developed by LANL for use by first responders in potential homeland security emergencies, such as the release of anthrax or other “weaponized” pathogens in biological terror attacks, dealing with a pandemic, or in case of an accidental release of dangerous germs or viruses.

BMCP has been given a non-exclusive license to develop the product for general medical applications, according to a news release from LANL. Based on prototype sensors developed at the National Lab, the diagnostic tools use laser light to identify potentially dangerous pathogens by “triggering fluorescence changes identified almost immediately by tiny-on-board detectors,” according to a LANL news release.

LANL, located at Los Alamos, NM, is managed for the U.S. Department of Energy by a consortium between four U.S. organizations, Bechtel National, University of California, BWX Technologies (a unit of Babcock & Wilcox), and the Washington Division of URS Corporation. BMCP is headquartered in Orangevale, CA.

Through the partnership with BMCP, the technology will be adapted for everyday use in making quick diagnoses. This could be extremely valuable in many everyday uses, including blood bank screening or for quick and convenient diagnosis in hospital emergency rooms or doctor’s offices.

Stirling Engines to Capture Sun’s Power

Tuesday, January 5th, 2010

By David L. Brown

A type of engine invented nearly 200 years ago by a Scottish clergyman may soon provide a practical solution to capturing energy from the Sun. Called the Stirling engine, it works from an external heat source, ideal for utilizing the concentrated rays of the Sun.

Originally intended to rival the steam engine, the invention of Rev. Robert Stirling never really caught on — until now. Sterling Energy Systems of Scottsdale, AZ has used the design as the basis for its innovative SunCatcher solar energy system, using the concentrated rays from reflective dishes to drive engines capable or producing 25 kilowatts each.

gallery_112_largeThe first working project is set to begin operation soon near Phoenix, AZ. The project, Maricopa Solar, LLC, is a partnership between Tessera Solar and the Salt River Project (SRP) electric utility. It will use 60 SunCatcher units to deliver 1.5 kilowatts of power for the Phoenix area power grid. SRP is committed to meet 15 percent of its retail energy needs from sustainable energy by 2025.

According to a news release from Sterling Energy Systems (SES), the Maricopa solar plant will “serve as a milestone for the development of the larger commercial projects previously announced in California and Texas totaling more than 1,600 megawatts.”

Each SunCatcher unit employs a highly reflective parabolic mirror that tracks the Sun to concentrate the Sun’s rays on receiver tubes containing hydrogen gas. The gas goes through an exchanger to heat an internal fluid that expands and contracts to drive a four-cylinder Stirling engine. Each engine in turn drives a generator.

SES bought original solar designs from McDonnell Douglas and Boeing in 1996, and partnered with Sandia National Laboratories in Albuquerque, NM to improve the technology over the next decade. In 2008 Sandia announced a new world record for solar efficiency had been set using the SunCatcher concept at its National Solar Thermal Test Facility (read more here).

According to SES, the SunCatcher is the most efficient solar power system, yielding agallery_100_large1 higher percentage of energy than any other present solar technology. A major advantage is that the system is scalable, that is, a large installation can begin to deliver power as soon as the first cluster of SunCatchers is installed.

A World Teetering on the Brink of Instability

Thursday, December 17th, 2009

By David L. Brown

A news release from Earth Policy Institute this morning features a peek at the subject of global stability as reported in Lester Brown’s new book Plan B 4.0. This is a critical issue because nations that are failing create difficulty for any response to climate change and resource depletion.

I was intrigued by the list Brown presents, a ranking of the Top 20 failing states in the world as of 2008 (the 2009 list is out now, and is essentially unchanged). The table is from Foreign Policy magazine, based on statistics developed by the Fund for Peace in cooperation with the magazine. Together they each year measure the instability index of the world’s nations, that is, the chances they are failing or have already failed. These are the worst-cases:

top_20_failing_states

The rankings are based on 1-10 scores in 12 critical areas, with 10 being the worst. Thus, a completely failed state will score 120 points. (It’s hard to imagine such a place; it would probably consist of radioactive slag.) It’s no surprise to see that Somalia is No. 1 with 114.7 points. Zimbabwe is less than a point behind, followed by Sudan, Chad and the Democratic Republic of the Congo.

It’s interesting to examine some of the other failed or failing states on this list. Extremely notable, to me at least, is that coming in Nos. 6 and 7 are nations familiar to most Americans … Iraq (108.6) and Afghanistan (108.2). These scores represent 90% of “perfect,” and yet we must scratch our head in puzzlement at the fact that our nation and many of its allies have spent the better part of a decade in the mission of creating successful democratic societies in those very places.

Now I am all in favor of peaceful democratic societies, but it’s generally been proven that nearly-failed states are not usually places where they are found. Does it make sense to attempt to plant the seeds of Western civilization in such infertile soil?

Iraq was formerly ruled by a ruthless dictator, “peace” being maintained under the iron-shod boot of tyranny. As Western troops depart, will that unhappy nation continue to move in the direction of “peaceful, Western-style democracy,” or will it break down into bloody rivalry between Shia, Sunni and Kurdish factions? As a very nearly failed state, the latter scenario seems a more likely outcome than the emergence of a Jeffersonian Golden Age.

And in Afghanistan, things are even worse. That benighted place has never really been a nation at all, but a ragtag collection of fiefdoms ruled over by warlords and funded by the opium trade. Even today, after years of military operations against them, the Taliban control wide areas of the region. Now that the U.S. has set its departure date for  2011, what hope is there for this failed state to suddenly thrive and grow into a peaceful member of the world’s democratic nations? To demonstrate my guess about the odds of that happening, try this experiment: Place one large snowball in a microwave oven; set the controls to “high” and the timer for ten minutes; and hit “cook”. Later as you mop up the floor, you’ll have a good analogy of what will likely be the future in Afghanistan, a place that has been impossible to rule since the days of Alexander the Great. Namely, a huge mess.

The place is absolutely unready to take responsibility for its own governance and security. The U.S. Marines have been assigned the task of training native Afghan soldiers, and according to a recent report from The Guardian, it’s a near fruitless exercise, dealing with illiterate, lazy, hash-smoking peasants who are completely ill-suited to function as modern-day soldiers.

So the outlook is dim for Afghanistan, No. 7 on the list  of Top 20 Failed States. But what can we learn from some of the others?

Well, there’s Pakistan right there at No. 10. The world’s sixth most populous nation, Pakistan is a nuclear power. How do you feel knowing that a nation that ranks 104.1 on an instability scale of 120 has nuclear bombs and missiles? Imagine how India feels, having to live right next door.

Pakistan isn’t the only unstable nation with a large population to make the list. Bangladesh, with a score of 98.1 is the seventh most populous nation, and right behind it is Nigeria, the eighth largest by population and a score of 99.8.

But that’s not all, for the Top 20 also includes North Korea, another nuclear power. Talk about instability!

Now, from the Fund for Peace website, here is a graphic to give you the “big picture” about world instability. You might be surprised and even dismayed, may even feel chills go up and down your spine. The nations colored in red are the most seriously failed or failing. There are presently 38 of them including Iran, another dangerous and potential nuclear power with a score of 90.0.

failedstatesYes, the red is where the most trouble is, but notice how much of the world is covered in orange, indicating a “warning” stage. And as far as those nations shown in green and judged “sustainable,” meaning safe, there are only 13 of them, not including the U.S., Britain, France, Germany, Japan and many other advanced nations. As you can see, Canada, Australia and New Zealand, along with Ireland and five Scandinavian countries including Iceland are the main “safe” places, along with Switzerland, Holland, Austria and Luxembourg.

In case you’re wondering, here are the scores for some of the “yellow” countries: Germany 36.2; France 35.3; United States 34.0; United Kingdom 30.5; Japan 31.2. And the “safest” place of all: Norway 18.3.

It is interesting to note that the further you get from the “center” as indicated by this map, the safer. Central Africa, the Middle East and a few nations along the fringe  of Asia are worst off, surrounded by a sea of orange. It is only when you get far away from these areas that the colors fade to yellow, and finally to green.

And all of these nations, with perhaps only a rare exception or two, are presently meeting in Copenhagen to discuss a global plan to cooperate in mitigating CO2 emissions, no doubt the greatest challenge humanity has ever faced. What could go wrong?

No End In Sight for Oil Price Troubles

Friday, June 12th, 2009

By David L. Brown

Just after I wrote the previous post about the up-and-down cycle of the petroleum markets, and their joined-at-the-hip effects on world economies, I saw the following news report on FoxNews.com. It makes an appropriate addendum to my musings on the subject.

Gas Prices Worry Longtime Oilman

June 12, 2009 – 3:08 pm

The price of oil has its ups and downs. But Tex Pitfield, a former fuel company president and petroleum industry consultant, says gone are the days of dollar a gallon gas.

With America still in a recession, Pitfield says the current spike in oil prices could not come at a worse time. Here’s what he told FOX News in a recent interview:

“The dramatic increase in the cost of energy last summer is what put this economy over the edge, and now we’re in the situation we’re in. How ironic that, here we are in the deep end of the pool drowning and the cost of energy is going through the roof again.”

More evidence for the case that the world economies are due for a continuing wave of shocks in the post Peak Oil era. And what is this “dollar a gallon gas” thing? I thought we passed that point a long time ago. The odds more strongly favor five dollar gas than any return to dollar gas.

For those of you who have not been around as long as I have, I can report that when I was a youth I purchased gas for as little as ten cents a gallon. For a dollar, you could nearly fill your tank. That surely puts the lie to the French saying “plus c’est la même chose” (the more things change, the more they stay the same). The longer I live, the more it seems the opposite is true.

An American Tragedy: Detroit Meets Reality

Sunday, December 21st, 2008

By David L. Brown

What lies in the future for the American automobile industry? I am a realist now, not a pessimist, so let’s look at the situation from a realistic point of view.

I note that sales of American automobiles and light trucks have dropped by somewhere north of 40 percent since last year. That was as of November, and December isn’t likely to improve that record. That is a substantial drop, and truly bad news for the auto makers.

One might like to think that with a little help they can get back on their feet in a few months and begin to sell new product again, get factories rolling, improve their cash position. But… There are some problems with that.

For one thing Detroit has continued to build cars and light trucks that they cannot sell. That might seem like a poor business decision, but it wasn’t really a current decision at all because years of contract negotiations with suppliers, unions and others set them up so that it is almost impossible to stop making cars that don’t sell. Union workers get paid whether they work or not. Suppliers are contracted to deliver parts and components to assembly factories on a just-in-time basis. Those supplies keep coming, so the auto companies are virtually forced to keep making the vehicles.

I read a report recently by someone who has business contacts with auto company facilities. He described how as he drove to a GM plant he noticed that every abandoned shopping center or unused parking lot for miles around was packed with new, unsold cars. The same story can be seen anywhere that cars or light trucks are made. Dealer lots are also overflowing with inventory and the seriousness of the situation can be measured by the offer I received a few months ago to buy a brand-new 2008 Dodge quarter-ton pickup for 50 percent off of the MSRP. Half-price sales on expensive-to-produce items such as pickup trucks hint at an almost unimaginable level of desperation.

Here is a graph showing market share of U.S. auto sales by the top five manufacturers for the ten year period through November (credit: Wall Street Journal):

autosale.jpgIt is sad to report that the blue line represents GM sales, the orange line is for Ford, and the maroon line is for Chrysler. All zooming steadily down. But what about the other two lines? Sorry, but the green one is for Toyota and the brown one at the bottom represents Honda. The U.S. auto industry has been sinking steadily for more than a decade while Japanese companies took an increasing market share.

Now here is the graph for all U.S. auto sales for the past year, including imports and cars made in America by foreign companies:

48kikpmp.jpg

The blue bars indicate sales of cars and the tan bars represent light trucks. Notice the vicious downward trend starting about last June or July. Keep in mind that this trend is in spite of price reductions of as much as 50 percent off of list. The decline began when the gas prices went through the roof, but the high price of petroleum and other events were also creating other problems for the auto market. Credit began to dry up, causing the suspension of lease programs. Money for purchase loans began to be pulled back. And perhaps worst of all, consumers began to realize that the resale or trade-in values of their present vehicles were so low that they couldn’t afford to get rid of them.

Update on Continuing Arctic Melt Down

Sunday, September 21st, 2008

By David L. Brown

This is just a brief follow up to previous posts concerning the dwindling Arctic sea ice. Some climate change deniers have been hooting and hollering that the meltdown has reversed, because it appears that there will be slightly more sea ice this season than last year. However, last year was an extreme example, and this year’s melt is almost as great.

Here is the latest chart from the National Snow and Ice Data Center. The white area shows the present extent of sea ice, while the orange line shows the “normal” extent in the past. This is a pretty clear picture of a rapidly diminishing ice cover in the Arctic Ocean.

n_daily_extent_hires.jpg

All that open ocean within the orange line is free of ice and is still absorbing solar heat at a much higher rate than when the ocean was covered with ice and snow. It has also been reported that a larger proportion of the sea ice is “new,” having formed just last winter, and thus is thinner and more subject to future melting.

New Technologies Emerging for Solar Energy

Sunday, July 13th, 2008

By David L. Brown

There is an old saying about people who live in glass houses, but perhaps that is a model for the future. As it begins to sink in that cheap oil is a thing of the past, it is encouraging that some real progress appears to be taking place in the field of solar energy. For example, a story titled “High-Efficiency Organic Solar Concentrators for Photovoltaics” that appeared in the current issue of Science magazine describes a cheaper and effective method of creating electricity from the Sun’s rays.

The new approach relies on thin film dye coatings on regular glass, channeling the light into receptors at the edges of the glass. The panels do not have to rotate to face the sun, and the researchers at MIT predict the organic concentrator panels could be ready for the market in as little as three years, provide greater efficiency, and at lower cost than current solar collectors.

Here is a diagram from the ScienceDaily web site that reports on the new technology in this article:

080710142927-large.jpg

As the diagram shows, the dye particles that coat the glass transfers the light to the edges, where the solar cells convert it into electricity. By stacking two layers of collectors, both high voltage and low voltage power can be produced, enhancing the efficiency.

Because the panels can be mounted flat on roofs or other plane surfaces, they could easily be installed in many places. It could make it possible for owners of houses and commercial property to cut or even eliminate their electric costs, thus helping reduce the need for power produced with fossil fuels.

The new work from MIT isn’t the only news from the solar front. According to this article, also posted on the ScienceDaily site just a few days ago, an Australian researcher at Queensland University of Technology’s Institute of Sustainable Resources (ISR) has developed transparent windows that could reduce heating and cooling costs while producing electricity from the Sun. Here is an excerpt from the story:

Professor John Bell said QUT had worked with a Canberra-based company Dyesol, which is developing transparent solar cells that act as both windows and energy generators in houses or commercial buildings.

He said the solar cell glass would make a significant difference to home and building owners’ energy costs and could, in fact, generate excess energy that could be stored or onsold.

Professor Bell said the glass was one of a number of practical technologies that would help combat global warming which was a focus of research at the ISR.

“The transparent solar cells have a faint reddish hue but are completely see-through,” Professor Bell said.

“The solar cells contain titanium dioxide coated in a dye that increases light absorption.

“The glass captures solar energy which can be used to power the house but can also reduce overheating of the house, reducing the need for cooling.”

Professor Bell said it would be possible to build houses made entirely of the transparent solar cells.

“As long as a house is designed throughout for energy efficiency, with low-energy appliances it is conceivable it could be self-sustaining in its power requirements using the solar-cell glass,” he said.

Imagine living in a house made entirely of glass and requiring nothing but the Sun to provide electricity, heating and cooling. Such a house would be the ultimate in green efficiency, although privacy issues would need to be addressed.

These are only two of the interesting new solar power possibilities that are coming over the horizon. As the cost of conventional energy continues to rise, there will be plenty of incentive for development and marketing of new alternatives such as these. One real bright feature of these new alternatives is that they do not rely on large quantities of silicon, which is expensive and in short supply.

What is needed now is government incentives to match, such as tax deductions, credits or grants for individuals or businesses that install environmentally friendly solar collectors. I know I would respond to such a program if it could be made affordable.

A couple of decades ago the government offered credits for the purchase of solar water heating systems, and the devices sold like hot cakes — until the subsidies were stopped. You don’t hear much about solar water heaters today, and that is too bad because hundreds of thousands of them could have been installed over the past couple of decades, helping to alleviate the current energy crisis. Congress and the administration could move the shift away from fossil fuels ahead by a giant step by instituting financial incentives to help people like me to take the move to solar.
