See Through Solar Panels





This is interesting though I would like to see more detail.  The use of organics asks more questions than it answers.  That it can out perform thin film by an order of magnitude implies converting over a much broader spectrum.  So far so good.  Can it be sustained?

This is a new entrant and the claims are at least promising.  Even if the production is nort particularly impressive, it will still have a market merely to make use of a passive resource.  Recall windows must be specially made to begin with, and it will be no trick at all folding this into the supply chain.

Of course, if they can establish sustainable high yield at a low effective cost base, every office building will soon convert and so will everyone else.  Recall how we all use double pane windows these days.

New Energy Technologies is pleased to announce that researchers developing its proprietary SolarWindow technology have achieved major scientific and technical breakthroughs, allowing the Company to unveil a working prototype of the world's first-ever glass window capable of generating electricity in the upcoming weeks.

Until now, solar panels have remained opaque, with the prospect of creating a see-thru glass window capable of generating electricity limited by the use of metals and various expensive processes which block visibility and prevent light from passing through glass surfaces.

New Energy's ability to generate electricity on see-thru glass is made possible by making use of the world's smallest working organic solar cells, developed by Dr. Xiaomei Jiang at the University of South Florida. Unlike conventional solar systems, New Energy's solar cells generate electricity from both natural and artificial light sources, outperforming today's commercial solar and thin-film technologies by as much as 10-fold.

New Energy's SolarWindow technology is under development for potential application in the estimated 5 million commercial buildings in America (Energy Information Administration) and more than 80 million single detached homes.

"We're always keen to see innovations in our laboratories turn into meaningful commercial products," stated Valerie McDevitt, Assistant Vice President for Research, Division of Patents and Licensing, University of South Florida. "We very much look forward to the commercial development of New Energy's SolarWindow technology, which, if successful, could literally transform the way in which we view the use of solar energy for our homes, offices, and commercial buildings."

The University of South Florida Research Foundation has licensed Dr. Xiaomei Jiang's groundbreaking discovery and important commercial processes and applications to New Energy Solar Corporation, a wholly-owned subsidiary of New Energy Technologies, Inc.

"It's very exciting to see that our ongoing research has led to several significant breakthroughs with transparency and the production of electricity on see-thru glass," explained Mr. Meetesh V. Patel, President and CEO of New Energy Technologies, Inc. "For the first time ever, these advances have allowed us to develop an early-scale working prototype of the technology, which I very much look forward to unveiling in the upcoming weeks."

Ozone Improves Biofuel Production Efficiency






It is of some interest that direct application of ozone degrades the lignin allowing the carbohydrates to be attacked and converted to sugars.  It will not be easy, but it opens another avenue.

Ozone is a bit tricky to produce and expensive and may well limit this method to the laboratory.

However, a process protocol that starts and ends dry is a rather good beginning and leaves a lot of options open for further treatment and no immediate waste stream.

A friend of mine has been testing ozone on ores to some effect, so this is not too surprising.


New Technique Improves Efficiency Of Biofuel Production

Researchers at North Carolina State University have developed a more efficient technique for producing biofuels from woody plants that significantly reduces the waste that results from conventional biofuel production techniques. The technique is a significant step toward creating a commercially viable new source of biofuels.

"This technique makes the process more efficient and less expensive," says Dr. Ratna Sharma-Shivappa, associate professor of biological and agricultural engineering at NC State and co-author of the research. "The technique could open the door to making lignin-rich plant matter a commercially viable feedstock for biofuels, curtailing biofuel's reliance on staple food crops."

Traditionally, to make ethanol, butanol or other biofuels, producers have used corn, beets or other plant matter that is high in starches or simple sugars. However, since those crops are also significant staple foods, biofuels are competing with people for those crops.

However, other forms of biomass - such as switchgrass or inedible corn stalks - can also be used to make biofuels. But these other crops pose their own problem: their energy potential is locked away inside the plant's lignin - the woody, protective material that provides each plant's structural support.
Breaking down that lignin to reach the plant's component carbohydrates is an essential first step toward making biofuels.

At present, researchers exploring how to create biofuels from this so-called "woody" material treat the plant matter with harsh chemicals that break it down into a carbohydrate-rich substance and a liquid waste stream. These carbohydrates are then exposed to enzymes that turn the carbohydrates into sugars that can be fermented to make ethanol or butanol.

This technique often results in a significant portion of the plant's carbohydrates being siphoned off with the liquid waste stream. Researchers must either incorporate additional processes to retrieve those carbohydrates, or lose them altogether.

But now researchers from NC State have developed a new way to free the carbohydrates from the lignin. By exposing the plant matter to gaseous ozone, with very little moisture, they are able to produce a carbohydrate-rich solid with no solid or liquid waste.

"This is more efficient because it degrades the lignin very effectively and there is little or no loss of the plant's carbohydrates," Sharma-Shivappa says. "The solid can then go directly to the enzymes to produce the sugars necessary for biofuel production."

Sharma notes that the process itself is more expensive than using a bath of harsh chemicals to free the carbohydrates, but is ultimately more cost-effective because it makes more efficient use of the plant matter.

The researchers have recently received a grant from the Center for Bioenergy Research and Development to fine-tune the process for use with switchgrass and miscanthus grass. "Our eventual goal is to use this technique for any type of feedstock, to produce any biofuel or biochemical that can use these sugars," Sharma-Shivappa says.

The research, "Effect of ozonolysis on bioconversion of miscanthus to bioethanol," was co-authored by Sharma-Shivappa, NC State Ph.D. student Anushadevi Panneerselvam, Dr. Praveen Kolar, an assistant professor of biological and agricultural engineering at NC State, Dr. Thomas Ranney, a professor of horticultural science at NC State, and Dr. Steve Peretti, an associate professor of chemical and biomolecular engineering at NC State.

The research is partially funded by the Biofuels Center of North Carolina and was presented June 23 at the 2010 Annual International Meeting of the American Society for Agricultural and Biological Engineers in Pittsburgh, PA.

NC State's Department of Biological and Agricultural Engineering is a joint department of the university's College of Engineering and College of Agriculture and Life Sciences.

Air Strike on Iran Nuclear Assets Possible Now





When I posted two or three weeks ago that an American supported Israeli air strike was possibly eminent because the necessary assets had moved in place, I still lacked the reason as to why just now.  This tells us why it will happen now.  Assume Russia will arrange to be standing by for this one and to also be in the know.  They may be selling a reactor, but they want a nuclear weapon in these fool’s hands no more than we do.  Think of the rich targets for Islam in Russia.

A surgical strike is likely to happen this week.  The purpose will be to smash up the reactor itself.  The only interesting question is how the Iranian air force will be neutralized while the attack goes in, particularly if they wish to have a back up wave.  I assume the US will not be visible.

Iran’s reaction will be of serious interest.  The most damaging thing that they could do in the short term is to suspend oil shipments to the extent that they can.  This could precipitate a jump in oil prices to the $150 mark and generate a sharp decline in stock prices.  That though should be the most effect their actions may have.

In the medium term, regime control of the population will likely spiral out of control because the population will immediately blame the regime for bringing this attack on to themselves.  Discontent is also likely to become visible in the armed forces because of the regime’s reckless behavior and proven futility.  In short, the regime will be destabilized.

Beyond what we have just described, they have no creditable response.

I note from this map that the reactor is on the Persian Gulf itself.    Any attack seems way more difficult and may target the secondary assets instead.  In the event, we have reached a decision point.


John Bolton: Russia's Loading of Nuke Fuel Into Iran Plant Means Aug. 21 Deadline for Israeli Attack

Friday, 13 Aug 2010 01:41 PM

News that Russia will load nuclear fuel rods into an Iranian reactor has touched off a countdown to a point of no return, a deadline by which Israel would have to launch an attack on Iran's Bushehr reactor before it becomes effectively "immune" to any assault, says former Bush administration U.N. Ambassador John R. Bolton. 

Once the fuel rods are loaded, Bolton told Fox News on Friday afternoon, "it makes it essentially immune from attack by Israel. Because once the rods are in the reactor an attack on the reactor risks spreading radiation in the air, and perhaps into the water of the Persian Gulf." 

Russian Prime Minister Vladimir Putin declared in March that Russia would start the Bushehr reactor this summer. But the announcement from a spokesman for Russia's state atomic agency to Reuters Friday sent international diplomats scrambling to head off a crisis. 

The story immediately became front-page news in Israel, which has laid precise plans to carry out an attack on Iran's nuclear facilities while going along with President Obama's plans to use international sanctions and diplomatic persuasion to convince Iran's clerics not to go nuclear. 

Bolton made it clear that it is widely assumed that any Israeli attack on the Bushehr reactor must take place before the reactor is loaded with fuel rods.

"If they're going to do it that's the window that they have," Bolton declared. "Otherwise as I said before, once the rods are in the reactor, if you attack the reactor you're going to open it up and radiation will escape at least into the atmosphere and possibly into the waters of the Persian Gulf.


"So most people think that neither Israel nor the United States, come to that, would attack the reactor after it's been fueled."

Bolton cited the 1981 Israeli attack on Saddam Hussein's Osirak reactor outside Baghdad and the September 2007 Israeli attack on a North Korean reactor being built in Syria. Both of those strikes came before fuel rods were loaded into those reactors.

"So if it's going to happen in Bushehr it has to happen before the fuel rods go in," Bolton said. 

The conversation that touched off the de facto deadline for Israeli military action was a telephone conversation with wire services involving Sergei Novikov, a spokesman for Rosatom, the Russian Energy State Nuclear Corp. 

Novikov said: "The fuel will be loaded on Aug 21. This is the start of the physical launch” of the reactor.

"From that moment the Bushehr plant will be officially considered a nuclear-energy installation," Novikov said, adding that the head of Rosatom, Sergei Kiriyenko, will visit Bushehr Aug. 21 to conduct a ceremony for the event.
According to Bolton, once the reactor is operational, it is only a matter of time before it begins producing plutonium that could be used in a nuclear weapon.

"And in the normal operation of this reactor, in just a fairly short period of time, you could get substantial amounts of plutonium to use as nuclear weapons," Bolton told Fox. 

Russia, which is operating under a $1 billion contract with Iran, has spent more than a decade building the reactor. If Russia moves forward with its plan to fuel the reactor, it could be seen as a major setback to the Obama administration's strategy of engaging Russian leaders in order to win their cooperation.

"The U.S. urged them not to send the Iranian's fuel rods," Bolton said. "They did that. The Obama administration has urged them not to insert the fuel rods in the reactors, but as they've just announced that will begin next week. What that does over time is help Iran get another route to nuclear weapons through the plutonium they could reprocess out of the spent fuel rods."

The developments mean Israeli Prime Minister Benjamin Netanyahu soon may face a stark choice: Attack the Bushehr reactor in the next 8 days, or allow it to become operational despite the certainty it would greatly enhance Iran's ability to create nuclear weapons. 

Russian leaders have said the Bushehr reactor project is being closely monitored by the International Atomic Energy Agency (IAEA), the UN's nuclear watchdog group. According to Iran's ISNA news agency, IAEA inspectors will be on hand to observe the fuel-rod loading process that is now scheduled to begin Aug. 21. 

According to Russian officials, Iran has promised in writing to send all spent fuel rods from Bushehr back to Russia for reprocessing, to ensure they cannot be used for nuclear weapons.


Bolton said the reactor has been "a hole" in American foreign policy for over a decade.

The failure to demand it be shut down began in the Bush years, he said, and continues with the Obama administration "under what I believe is the mistaken theory that Iran is entitled to the peaceful use of nuclear energy."

"I don't think Iran is entitled to that, or I don't think we ought to allow it to happen, because they're manifestly violating any number of obligations under the non-proliferation treaty not to seek nuclear weapons. But this has been a hole in American policy for some number of years, and Iran and Russia are obviously exploiting it," Bolton said.

Russia’s move would put Iran "in a much better position overall," he said, adding, "I think this is a very delicate point, as I say, it closes off to the Israelis one possible target for pre-emptive military action.

U.N. sanctions against Iran, he said, "have not had and will not have any material effect on Iran's push to have deliverable nuclear weapons."
