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

Raleigh NC (SPX) Jul 06, 2010



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
By: David A. Patten


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."

Unregulated Greed has Destroyed the Capitalist System




There is much to agree with and plenty to argue against with here but the view point needs to be read.

1                    The break up of AT&T was not a mistake.  I will take it further, at some point. All super large organizations need to be subdivided on some rational basis.  ATT&T actually did an excellent job in that regard.  Others may well make a hash out of it.

My reasoning is simple.  Cheaper access to more money through size is usually a serious error because it ultimately lowers the real return that management may achieve.  There are exceptions, yet Warren Buffet has found his point of resistance.  It is vastly more profitable to nurture many small companies that are then spun out, as actually happened under ATT&T.

Besides, the digital age was happening and the wall of monopoly barriers needed to be pulled down as fast as possible.  This way it took less than a decade and prevented billions of dollars been diverted to monopoly profits and paychecks.

2          Off shoring is a problem hugely driven by the failure of the US to reform its tax code.  By not imposing a VAT tax, the USA gives every other country an economic advantage. That encourages the transfer of manufacturing offshore.  Solve that and much of the problem will fade as a far leveler playing field will exist.

Right now a company has an equal opportunity to place a factory in the US or India.  Cheap labor is one of a very short list of deciding factors but tax on sales is an immediate claim on cash flow.  It you are in the USA you pay it on all exports now, often before you get paid.  It you are in the rest of the world, you pay it also, but you offset it with tax you pay on costs.  This is a huge and immediate advantage that can not be dodged.

Since most investments are initially deemed as risky, the corporation that plans to export will find it more prudent to build were this drag does not exist.

Otherwise, stop counting their jobs and observe that our incomes have not risen appreciably since 1980, yet our purchasing power from the same dollar bill has leapt ahead, not in specifics but in the expansion of cheaper choices.

3          Yes, greed must be regulated.  Except the pigs have the coin to buy off the politicians who are ill educated economically and are all suckers to begin with.  Tell me how to change that now.


"Unregulated Greed has Destroyed the Capitalist System": The Big Things That Matter And The Little Things That Annoy

By Paul Craig Roberts




I write about major problems:  the collapsing US economy, wars based on lies and deception, the police state based on “the war on terror” and other fabrications such as those orchestrated by corrupt police and prosecutors, who boost their performance reports by convicting the innocent, and so on.  America is a very distressing place. The fact that so many Americans are taken in by the lies told by “their” government makes America all the more depressing.


Often, however, it is small annoyances that waste Americans’ time and drive up blood pressures. One of the worst things that ever happened to Americans was the breakup of the AT&T telephone monopoly. As Assistant Secretary of the US Treasury in 1981, if 150 percent of my time and energy had not been required to cure stagflation in the face of opposition from Wall Street and Fed Chairman Paul Volcker, I might have been able to prevent the destruction of the best communications service in the world, and one that was very inexpensive to customers. 


The assistant attorney general in charge of the “anti-trust case” against AT&T called me to ask if Treasury had an interest in how the case was resolved.  I went to Treasury Secretary Don Regan and told him that although my conservative and libertarian friends thought that the breakup of At&T was a great idea, their opinion was based entirely in ideology and that the practical effect would not be good for widows and orphans who had a blue chip stock to see them through life or for communications customers as deregulated communications would give the multiple communications corporations different interests than those of the customers. Under the regulated regime, AT&T was allowed a reasonable rate of return on its investment, and to stay out of trouble with regulators AT&T provided excellent and inexpensive service.


Secretary Regan reminded me of my memo to him detailing that Treasury was going to have a hard time getting President Reagan’s economic program, directed at curing the stagflation that had wrecked 
President Carter’s presidency, out of the Reagan administration.  The budget director, David Stockman, and his chief economist, Larry Kudlow, had lined up against it following the wishes of Wall Street, and the White House Chief of Staff James Baker and his deputy Richard Darman were representatives of VP George H.W. Bush and did not want s substantial Reagan success that would again threaten the Republican Establishment’s hold over the party. Baker and Darman wanted to be sure that George H. W. Bush, and not Jack Kemp, succeeded Ronald Reagan, and that required a muted Reagan success that they could claim as theirs for moderating an “extremist” program. 


]I told Secretary Regan that if I had another deputy assistant secretary, I could reach a reasonable conclusion whether the breakup of AT&T was sensible. He replied that he was sure that was the case, but that once I had three deputies the headlines in the Washington Post and New York Times, Business Week, Newsweek, and so on, would be: “Supply-sider builds empire at Treasury.”  He said it would sink me and that without me he could not get the President’s economic program out of the President’s administration. “Which do you want to do,” he asked, “save AT&T or cure stagflation?”


Curing stagflation gave America twenty more years. Ironically, the good times started to erode when Reagan’s other goal was accomplished and the 
Soviet Union dissolved in 1990. “The end of history” resulted in India and China opening their labor markets to American capitalists, who began producing offshore with foreign labor the products that they sold to Americans. The labor costs savings pushed up corporate profits, shareholders’ returns, and managerial bonuses. But it deprived Americans of middle class incomes and wrecked the balance of trade. The US income distribution and the trade deficit worsened.


Many progressives blame the worsening income distribution  on the Reagan tax rate reductions, but the real cause is the offshoring of manufacturing, industrial, and professional service jobs, such as software engineering.


None of us in the Reagan administration foresaw jobs offshoring as the consequence of Soviet collapse. We had no idea that by bringing down the Soviet Union we would be bringing down America. During the Reagan years India was socialist and would not allow foreign corporations, had they been interested, to touch their labor force. China was communist and no foreign capital could enter the country.


However, once the Soviet Union was gone from the earth, the remaining socialist and communist regimes decided to go with the winners. They opened to Western corporations and sucked jobs out of the developed West.


But this is a different story. To get back to deregulation, nothing has worked for the consumer since deregulation. Deregulation permitted corporations to impose their costs of operation on customers without having to send them a bill. For example, corporations use voice recognition technology to keep customers from salaried customer representatives. I remember when a customer with a problem could call a utility company or bank and have the problem immediately corrected.


No more. There was an error in my phone bill today, which I had corrected without result on two previous occasions. As everyone knows by now, it takes 10-15 minutes, usually, to get a live person who can actually fix the problem.  After listening to sales pitches for 12 minutes, I got a live person. Once the problem was understood, it was pronounced to be an upper level problem out of his hands. I waited another 10 minutes while he tried to reach a superior who had the code to fix the problem that the phone company had produced in my account. The entire time I listened to product advertisements. 


How many times has this happened to you?


Whoever invented these artificial voice capabilities is the enemy of mankind. Whomever a customer calls--utilities, 
credit card companies, banks, whatever, the customer gets a voice machine. Some voice machines never tell the customer how to get a live person who can, on occasion, actually fix the problem.


In my opinion, the strategy behind the endless delays is to cause the customers to give up, slam the telephone down and play the higher incorrect bill as it is cheaper in time and frustration to correcting the problem and being billed in the correct amount. These ripoffs of the customer are produced by Wall Street pressures for higher earnings. 


The frustrations, of course, multiply when one reaches an offshored service somewhere in the 
Third World. The incentive is to hang up and to pay the excessive bill so that phone, internet, or credit card services are not cut off


Had Don Regan and I known that the high speed Internet was in our future and that American corporations would use it to destroy the jobs traditionally filled by US university graduates, possibly we would have decided to save the regulated telephone monopoly and to deliver the economy over to stagflation.


The reason is that sooner or later something would have been done about stagflation, but nothing whatsoever has been done about offshoring. Saving the economy from offshoring would have been a greater achievement than saving the economy from stagflation. However, in my time stagflation, not offshoring, was the problem.

I regret that I did not have a crystal ball.


Deregulation proponents will say that the breakup of AT&T gave us cell phones and broadband, as if foreign regulated 
communication companiesand state monopolies do not provide cell phone service or high speed Internet connections. I can remember attending corporate board meetings years ago at which the European members had digital cell phones with which they could call most anywhere on earth, while we Americans with our analogue cell phones could hardly connect down the street.


What deregulation did was to permit Wall Street to push the deregulated industries-- phone service, airlines, trucking, and later Wall Street itself-- to focus on profits and not on service. Profits were increased by curtailing service, by pushing up prices and by  Wall Street creating fraudulent financial instruments, which the banksters used America’s reputation to market to the gullible at home and abroad. 


Consider air travel. Admit it, if you are my age you hate it. The deterioration in service over my lifetime is phenomenal. Studies in favor of airline deregulation focused on short flights between A and B and concluded that small airlines serving high density areas were more efficient because they were not regulated. What was left out of the analysis is that regulated airlines served low density areas and permitted free stopovers. For example, if one was flying from the US to Athens, Greece, the traveler could stopover in London, Paris, and Rome without additional charges. Moreover, passengers were fed hot meals even in tourist class. In those halcyon days, it was even possible to travel more comfortably in tourist class than in first class, because flights were not scheduled in keeping with full capacity. Several rows of seats might be unoccupied. It was possible to push up the arm rests on three or four center aisle seats, lay down and go to sleep.


Perhaps the best benefit of regulated air travel for passengers was that airlines had spare airliners. If one airplane had mechanical problems that could not be fixed within a reasonable time, a standby airliner was rolled out to enable passengers to meet their connections and designations. With deregulation, customer service is not important. The bottom line has eliminated spare airliners.


With deregulated airlines, Wall Street calls the tune. If your flight has a mechanical problem, you are stuck where you are unless you have some sort of privileged status that can bump passengers from later fully booked flights. “Studies” that focus only on discounted ticket price omit major costs of deregulation and thereby wrongly conclude that deregulation has benefited the consumer.


When trucking was regulated, truckers would stop to provide roadside assistant to stranded travelers. Today, with deregulated trucking, every minute counts toward the bottom line. Not only do truckers no longer stop to aid stranded travelers, they travel at excessive speeds that endanger automobile drivers. Trucks have expanded in size, weight and speed. Trucks raise the stress level on interstate highway drivers and destroy, at taxpayers expense, the roads on which they travel.


Conservatives and especially libertarians romanticize “free market unregulated capitalism.” They regard it as the best of all economic orders. However, with deregulated capitalism, every decision is a bottom-line decision that screws everyone except the shareholders and management. 


In America today there is no longer a connection between profits and the welfare of the people. Unregulated greed has destroyed the capitalist system, which now distributes excessive rewards to the few at the expense of the many.


If Marx and Lenin were alive today, the extraordinary greed with which Wall Street has infected capitalism would provide Marx and Lenin with a better case than they had in the 19th and early 20th centuries.

Focus Fusion Update




depend on secondary devices working in the protocol environment.  See my many postings on the topic focus fusion.

Let us be serious.  We are witnessing a real creditable effort to produce fusion power that is arguably plausible.




AUGUST 09, 2010

Lawrenceville Plasma Physics (LPP) is trying to achieve commercial nuclear fusion.

LPP is trying to get up to 100,000 joules in each pulse. 60 such pulses would be 6 million joules per second, which if converted at with only about 20% loss would be equal to a 5 megawatt generator. The generator would cost about $200,000 and enable power to be generated 50 times cheaper than today.
1.      The first good news is that, with the Lexan insulators and tungsten pins, the spark plugs have lasted through over 200 shots without breaking


2. the amount of current we are producing per firing capacitor has improved. We have achieved 1 MA at 27 kV with only 8 capacitors firing, something that required all 12 capacitors with the old spark plugs. We believe that the large size of the tungsten pins and the better distribution of current has reduced the inductance of the switches and led to the increase in current, which makes us more confident that we can reach the design current for FF-1 of 2.8 MA.


3. Despite careful adjustment of the spark gaps, the simultaneity of firing with the new spark plugs is worse than with the old ones, and on average, only five switches are firing on the trigger. We believe we know the cause and cure of this problem. We have ordered this new power supply, which will increase the charging voltage on the trigger from 20 to 40 kV and will arrive near the end of August. We think that by doubling the rate of rise of the trigger pulse, we will be able to get the trigger voltage up to at least 20 kV before it shorts. That, together with the capacitor voltage of 30 kV, should get us to the 50 kV needed to fire all of the switches together. Another Dense Plasma Fusion project in Las Vegas is working reliably with higher voltages. The best switches cost a lot and are complicated to maintain. On the other hand, spark gap switches (our kind) with much higher trigger voltages—120 kV vs our current 20 kV—have been made to function reliably recently
From these numbers, we can calculate the product n^2V (where n is density and V is volume) for both the electrons and the ions. Both numbers are the same, 1.1+-0.1x10^35/cm^3. This is a strong indication that the X-rays and neutrons come from the same plasma, the plasmoid. It is also a good indication of how our instruments are designed to supplement and confirm each other, so that every measurement we take will be checked by at least two instruments


Biochar for Carbon Sequestration Study



This work is on a recent study done to evaluate the effect that adoption of biochar throughout the globe may have in terms of carbon sequestration.

The take home is that present regimes could comfortably handle up to fifteen percent of the CO2 produced and vented presently.

However, the real certainty is that we will be exiting the fossil fuel business over the coming century.  We are witnessing the first moves there in the massive emergence of successful wind energy production.  The real break will be fusion energy when we master that art.  In the meantime, Geothermal and solar will also emerge now at a great clip.
When we exit the fossil business also reforest the maximum open land which will massively increase the globe’s biomass, we are likely to swiftly create a CO2 deficit and will need to burn fossil fuels to make up the difference.

1.8 billion metric tons of carbon applied to land at say ten tons per acre will produce 200 million acres of fully involved terra preta soils.  This works out to be around a quarter million square miles per year.  Of course, in time we can just keep on adding carbon to fully involved soils but that then will not likely be necessary.

Also, as I have already posted, logistics and handling issues will likely make corn husbandry as the go to crop for this.  Most other crops simply produce too little usable waste.

And in spite of the ongoing chatter about using waste wood, it is not the first choice in terms of soils.  Most likely there the biochar will be screened for a fines fraction while the balance is used as a fuel for which it is well suited.

Offsetting greenhouse gas emissions using charcoal
00:11 August 11, 2010

According to a new study, as much as 12 percent of the world’s human-caused greenhouse gas emissions could be sustainably offset by producing biochar, a charcoal-like substance made from plants and other organic materials. That’s more than would be offset if the same plants and materials were burned to generate bioenergy, says the study. Additionally, biochar could improve food production in the world’s poorest regions as it increases soil fertility.

Biochar is made by decomposing biomass like plants, wood and other organic materials at high temperature in a process called slow pyrolysis – a form of incineration that decomposes organic materials by heat in the absence of oxygen. Normally, biomass breaks down and releases its carbon into the atmosphere within a decade or two. But biochar is more stable and can hold onto its carbon for hundreds or even thousands of years, keeping greenhouse gases like carbon dioxide out of the air longer.

Other biochar benefits include: improving soils by increasing their ability to retain water and nutrients; decreasing nitrous oxide and methane emissions from the soil into which it is tilled; and, during the slow pyrolysis process, producing some bio-based gas and oil that can offset emissions from fossil fuels.

The carbon-packed substance was first suggested as a way to counteract climate change in 1993. Scientists and policymakers have given it increasing attention in the past few years and this new study conducted by a collaborative team from the Department of Energy’s Pacific Northwest National Laboratory (PNNL), Swansea UniversityCornell University, and the University of New South Wales, is the most thorough and comprehensive analysis to date on the global potential of biochar.

The study
For their study, the researchers looked to the world’s sources of biomass that aren’t already being used by humans as food. For example, they considered the world’s supply of corn leaves and stalks, rice husks, livestock manure and yard trimmings, to name a few. The researchers then calculated the carbon content of that biomass and how much of each source could realistically be used for biochar production.

With this information, they developed a mathematical model that could account for three possible scenarios. In one, the maximum possible amount of biochar was made by using all sustainably available biomass. Another scenario involved a minimal amount of biomass being converted into biochar, while the third offered a middle course. The maximum scenario required significant changes to the way the entire planet manages biomass, while the minimal scenario limited biochar production to using biomass residues and wastes that are readily available with few changes to current practices.

The researchers found that the maximum scenario could offset up to the equivalent of 1.8 petagrams – or 1.8 billion metric tons – of carbon emissions annually and a total of 130 billion metric tons throughout in the first 100 years. Avoided emissions include the greenhouse gases carbon dioxide, methane and nitrous oxide. The estimated annual maximum offset is 12 percent of the 15.4 billion metric tons of greenhouse gas emissions that human activity adds to the atmosphere each year. Researchers also calculated that the minimal scenario could sequester just under 1 billion metric tons annually and 65 billion metric tons during the same period.

Making biochar sustainably requires heating mostly residual biomass with modern technologies that recover energy created during biochar’s production and eliminate the emissions of methane and nitrous oxide, the study also noted.

Biochar and bioenergy

Instead of making biochar, biomass can also be burned to produce bioenergy from heat. Researchers found that burning the same amount of biomass used in their maximum biochar scenario would offset 107 billion metric tons of carbon emissions during the first century. The bioenergy offset, while substantial, was 23 metric tons less than the offset from biochar.

Researchers attributed this difference to a positive feedback from the addition of biochar to soils. By improving soil conditions, biochar increases plant growth and therefore creates more biomass for biochar productions. Adding biochar to soils can also decrease nitrous oxide and methane emissions that are naturally released from soil.



However, the researchers say a flexible approach including the production of biochar in some areas and bioenergy in others would create optimal greenhouse gas offsets. Their study showed that biochar would be most beneficial if it were tilled into the planet’s poorest soils, such as those in the tropics and the Southeastern United States.

Those soils, which have lost their ability to hold onto nutrients during thousands of years of weathering, would become more fertile with the extra water and nutrients the biochar would help retain. Richer soils would increase the crop and biomass growth – and future biochar sources – in those areas. Adding biochar to the most infertile cropland would offset greenhouse gases by 60 percent more than if bioenergy were made using the same amount of biomass from that location, the researchers found.

On the other hand, the authors wrote that bioenergy production could be better suited for areas that already have rich soils - such as the Midwest – and that also rely on coal for energy. Their analysis showed that bioenergy production on fertile soils would offset the greenhouse gas emissions of coal-fired power plants by 16 to 22 percent more than biochar in the same situation.



Sustainability

The study also shows how sustainable practices can make the biochar that creates these offsets.

“The scientific community has been split on biochar,” says PNNL’s Jim Amonette. “Some think it’ll ruin biodiversity and require large biomass plantations. But our research shows that won’t be the case if the right approach is taken.”

The researchers’ estimates of avoided emissions were developed by assuming no agricultural or previously unmanaged lands will be converted for biomass crop production. Other sustainability criteria included leaving enough biomass residue on the soil to prevent erosion, not using crop residues currently eaten by livestock, not adding biochar made from treated building materials to agricultural soils and requiring that only modern pyrolysis technologies – those that fully recover energy released during the process and eliminate soot, methane and nitrous oxide emissions – be used for biochar production.

“Roughly half of biochar’s climate-mitigation potential is due to its carbon storage abilities,” Amonette said. “The rest depends on the efficient recovery of the energy created during pyrolysis and the positive feedback achieved when biochar is added to soil. All of these are needed for biochar to reach its full sustainable potential.”
