Hydro/Wind Power Followup
The BPA and the wind community apparently believe that storage of wind and hydro power are too expensive. Please read the following article from the Tacoma News Tribune about hydrogen. Also below is a link to a patented system for converting excess hydro into hydrogen.

With Columbia Gorge turbines pumping out extra electricity, the agency had to quickly adjust its hydro generation"
This was a story in the Saturday, July 05, 2008 Oregonian Newspaper by Gail Kinsey Hill, a staff writer. The gist of the story was that the greatly increased capacity of the wind turbines along the Columbia Gorge through which the Mighty Columbia River flows came close to causing a big problem on the BPA power generating dams. In order to deal with the surplus of electricity, the dams had to stop generating power and spill water over the dam thus potentially causing a problem with migrating salmon. My question is why the excess capacity of either the windmills or the dams could not be converted to hydrogen and stored for later use. Lacking an infrastructure to deliver hydrogen to other places where it could be used, it could be stored on site and used later to power generators or produce electricity when needed using fuel cells.
As a side note, as the old economy of the river based on aluminum smelting is in decline, a significant part of the BPA output is used by Google in it's semi-secret server farm in The Dalles on the banks of the Columbia. Despite Google's efforts to conserve, lots of power is used to run the servers and to cool the plant. Read about this in this Willamette Week article.

Power and Control
Power and Control
A good deal of my ramblings are about power, energy, conservation and alternative energy issues. The blog cited above is by M. Simon of Rockford Illinois. His focus is on energy also, but with a focus on fusion energy. Of late, there is a renewed interest in nuclear power as it does not directly contribute to global warming. I heard a podcast debate between one of the early Greenpeace guys who went over to the dark side and a member of the British Green Party on this issue. The debate featuring Partrick Moore can be heard by clicking this link.
The Green response is that Moore ignores the huge carbon footprint left by nuclear power when the mining, transportation and disposal of the fuel is taken into account. This argument left me questioning my recent conversion back to supporting nukes, but I am not good enough at the Dismal Science of economics to really come to any conclusions.
Finally, it should be said that I am a space nut. Perhaps He3 (an isotope of Helium) will play a role in fusion. Indeed, this might be why China, Japan and perhaps India have begun moon exploration programs. My view on this is the more the merrier. To the Moon, to Mars and beyond!
I do believe, however, that nuclear fusion might be the answer. See the blog cited above for more info on this. A bigger question, however, is whether or not we need unlimited power. Could it be that our lives would be simpler and more satisfying if we simply conserved for the sake of conserving? Go top M. Simon's blog and start a discussion on this!

Is Fusion back in vogue? BBC says that the new approach to smaller reactors means Fusion is "within reach". Even if we could get cheap, clean, unlimited power, do we want to? Or is it better to scale down our lives strictly for it's own sake?

New Source for Biofuels Discovered by Researchers at The University of Texas at Austin | The University of Texas at Austin
New Source for Biofuels Discovered by Researchers at The University of Texas at Austin | The University of Texas at Austin: "AUSTIN, Texas — A newly created microbe produces cellulose that can be turned into ethanol and other biofuels, report scientists from The University of Texas at Austin who say the microbe could provide a significant portion of the nation's transportation fuel if production can be scaled up.
Along with cellulose, the cyanobacteria developed by Professor R. Malcolm Brown Jr. and Dr. David Nobles Jr. secrete glucose and sucrose. These simple sugars are the major sources used to produce ethanol.
'The cyanobacterium is potentially a very inexpensive source for sugars to use for ethanol and designer fuels,' says Nobles, a research associate in the Section of Molecular Genetics and Microbiology."
The above is from the University of Texas at Austin News. As the article describes it, the problem with converting regular plant material to ethanol fuel is the difficulty and expense of breaking down the material. This process may eventually solve that problem as the new material involves cynobacteria that can be grown in production facilities or in land not suitable for agriculture using water to salty for regular use. Maybe we are not doomed!
Speaking of Not Doomed, try this at home:
From the Slashdot Blog
Newscloud brings us news of a startup called E-Fuel promising to ship a home-brew ethanol plant, the size of a washer-dryer, for under $10,000 by the end of this year. We've had plenty of discussions about $1/gal. fuel — these guys want to let you make it at home. The company says it plans to develop a NAFTA-enabled distribution network for inedible sugar from Mexico at 1/8th the cost of trade-protected sugar, to use as raw material for making ethanol. A renewable energy expert from UC Berkeley is quoted: "There's a lot of hurdles you have to overcome. It's entirely possible that they've done it, but skepticism is a virtue."

Nuclear energy becoming less sustainable | COSMOS magazine
Nuclear energy becoming less sustainable | COSMOS magazine
"SYDNEY: The case for nuclear power as a sustainable alternative energy source is challenged by new evidence that greenhouse gas emissions from uranium mining are increasing.
An Australian report, detailed this week in the journal Environmental Science and Technology argues that the availability of high-grade uranium ore will deplete over time making the fuel more environmentally and economically expensive to extract."
Just when it starts to look like "Good Nukes", the bad news comes. The above quoe is from Cosmos MagazineBelow is a quote from another source about the carbon footprint of nukes, citing the total process of generating nuclear energy: "As Michel Lee, chair of the Council on Intelligent Energy & Conservation Policy, wrote in an (unpublished) letter to the Times, the dirty secret is that nuclear power makes a substantial contribution to global warming. Nuclear power is actually a chain of highly energy-intensive industrial processes. These include uranium mining, conversion, enrichment and fabrication of nuclear fuel; construction and deconstruction of the massive nuclear facility structures; and the disposition of high-level nuclear waste." This quote is from a statement from a website maintained by the Orcanic Consumers Organization
I will try to find a link to a BBC broadcast of a recent debate in Great Britain between members of the Green Party and a "co-founder" of Greenpeace, Patrick Moore. I myself am not a big fan of most Green parties, but they can be correct. Maybe the old adage "If it sounds to good to be true, it probably isn't". Refer back to the quote from Lewis L. Stauss head of the AEC in the early 1950's: "It is not too much to expect that our children will enjoy in their homes electrical energy too cheap to meter, will know of great periodic regional famines in the world only as matters of history, will travel effortlessly over the seas and under them and through the air with a minimum of danger and at great speeds, and will experience a lifespan far longer than ours as disease yields and man comes to understand what causes him to age." We are still waiting!
Please, someone convince me that nukes will work and won't contribute to global warming! All of those French Folks can't be wrong, can they? That country gets a very large percentage of its power from nukes. See the CNN link for a story on the countries in the world with the largest number of nuclear plants.

"Having so far failed to find evidence for extraterrestrial civilizations by searching for their radio transmissions, some physicists think it is worth scouring the sky for signs of their astronomical construction work, writes Bruce Dorminey"
As physicist Enrico Fermi said, if they are out there, where are they? The Drake Equation postulates that they are there, based of course on some variables such as how long a civilization lasts as soon as it develops the power to destroy itself. This article talks about looking for advanced extraterrestrial civilizations who may have reached the K2 stage of civilization ( levels of civilizations postulated by Soviet physicist Nicolai Kardashev and commented on recently by physicist Michio Kaku) at which point a society could harness the energy of a star and build a "Dyson Sphere" around their star. The Physics World article calls for a new search for evidence of such super civilizations.

A Test for String Theory After All? Or Just PR? | Wired Science from Wired.com
A Test for String Theory After All? Or Just PR? | Wired Science from Wired.com
At last? String Theory has been around for a while. However, most authorities considered it as only an interesting speculation as there was thought to be no way to test the theory, therefore taking it out of the realm of science.
See the Wikepedia entry below:
Problems and controversy
Although historically string theory is an outgrowth of physics, some contend that string theory should (strictly speaking) be classified as something other than science. For a scientific theory to be valid it must be verified empirically, i.e. through experiment or observation. Few avenues for such contact with experiment have been claimed.[20] With the construction of the Large Hadron Collider in CERN some scientists hope to produce relevant data, though it is widely believed that any theory of quantum gravity would require much higher energies to probe directly. Moreover, string theory as it is currently understood has a huge number of equally possible solutions.[21] Thus it has been claimed by some scientists that string theory may not be falsifiable and may have no predictive power.[22][23][24][25]"

Origins: CERN: Ideas: The Higgs Boson
The Search for the Higgs Boson. What is it? See below. Also, see CERN
There, you will learn about the Swiss-French particle accelerator that will open in April to find both the Higgs Boson and perhaps create a very small black hole!
Origins: CERN: Ideas: The Higgs Boson: "An oft-cited analogy describes it well: Imagine you're at a Hollywood party. The crowd is rather thick, and evenly distributed around the room, chatting. When the big star arrives, the people nearest the door gather around her. As she moves through the party, she attracts the people closest to her, and those she moves away from return to their other conversations. By gathering a fawning cluster of people around her, she's gained momentum, an indication of mass. She's harder to slow down than she would be without the crowd. Once she's stopped, it's harder to get her going again.
This clustering effect is the Higgs mechanism, postulated by British physicist Peter Higgs in the 1960s. The theory hypothesizes that a sort of lattice, referred to as the Higgs field, fills the universe."

"Working in Haiti, Shawn Frayne, a 28-year-old inventor based in Mountain View, Calif., saw the need for small-scale wind power to juice LED lamps and radios in the homes of the poor. Conventional wind turbines don't scale down well—there's too much friction in the gearbox and other components. "With rotary power, there's nothing out there that generates under 50 watts," Frayne says. So he took a new tack, studying the way vibrations caused by the wind led to the collapse in 1940 of Washington's Tacoma Narrows Bridge (aka Galloping Gertie)."
The new alternative energy sources keep coming on line. Any of you from the Seattle Tacoma area will be very familiar with Gertie.

Antimatter molecule could lead to ultra-powerful laser - tech - 18 September 2007 - New Scientist Tech
Just in time for talk like a pirate day! A pirate could sure make use of this short-lived anti-matter ray. This is from the magazine New Scientist.
"Antimatter molecule could lead to ultra-powerful laser
An exotic molecule built from electrons and antimatter is being touted as a route to powerful gamma-ray lasers.
An electron can hook up with its antiparticle, the positron, to form a hydrogen-like atom called positronium (Ps). It survives for less than 150 nanoseconds before it is annihilated in a puff of gamma radiation. It was known that two positronium atoms should be able to bind together to form a molecule, called Ps2, and now David Cassidy and Allen Mills from the University of California, Riverside, have made that happen. First, they trapped positrons in a thin film of porous silica. Those positrons captured electrons to form positronium atoms, and the pattern of decay rates signalled that some of these atoms had teamed up to form Ps2 (Nature, DOI: 10.1038/nature06094)."

APOD: 2007 August 27 - Huge Void Implicated in Distant Universe
"Explanation: What has created this huge empty volume in the universe? No one is yet sure, and even the extent of the estimated billion-light year void is being researched. The void is not a hole in space like a black hole, but rather a vast region of the universe that appears to be mostly devoid of normal matter and even dark matter. The void is still thought to contain dark energy, though, and is clearly traversable by light. The void's existence is being postulated following scientific curiosity about how unusually cold spots came to appear on WMAP's map of cosmic microwave background (CMB) radiation. One possibility was that this CMB region was not actually very cold but light from the spot somehow became more cosmologically redshifted than normal along the way.'
From NASA's Astronomy Picture of the Day. That void is like my appetite is most of the time!! I still don't grasp the concept of Dark Energy or Dark Matter. Okay, maybe dark matter, but dark energy! These slow down the expansion of the universe. Also, see the Pioneer Anomaly.
Two Pioneer spacecraft, launched 30 years ago on a mission to the outer solar system, are now leaving the immediate vicinity of the solar system. While they are not yet in interstellar space, their speeds and trajectories do not match Newtonian and Einsteinian predictions. Either there is something new in gravity or problems in measurements or math. See the link for some new thoughts on the matter.
