Qataris looking to the sun for energy.

Uploaded by AlJazeeraEnglish on 30 Dec 2011 - The Gulf is home to two-thirds of the world's oil reserves, but alternative energy campaigners warn that those will not last forever.
In Qatar, one such campaigner argues that the country should turn towards the sun to meet future energy needs.

2012 : Occupy protests 'could intensify'

Uploaded by AlJazeeraEnglish on 30 Dec 2011 - Todd Gitlin, a professor of journalism and sociology at Columbia University in New York, spoke to Al Jazeera about the Occupy protest movement in the US. He said that the movement reflected "anger at the impunity with which the wealthy walked away from the consequences of having brought down the world economy." "It is anger at a system of inequality that has been entrenched and normal. There is a collective wish for a system that is more humane."

He also said he expects Occupy protests to intensify in 2012. "I think well see more attempts to take over buildings that have been foreclosed. We will also see protests directed at specific banks, at specific political candidates."

Revolution in Solar Energy Technology? Cheap Quantum Dot Solar Paint.

Researchers have reduced the preparation time of quantum dot solar cells to less than an hour by changing the form to a one-coat quantum dot solar paint. How?

Titanium dioxide (TiO2) nanoparticles are coated with cadmium sulfide (CdS) or cadmium selenide (CdSe.) The composite nanoparticles, when mixed with a solvent, form a paste that can be applied as one-step paint to a transparent conducting material, which creates electricity when exposed to light. 

Although the paint form is currently about five times less efficient than the highest recorded efficiency for the multifilm form, the researchers predict that its efficiency can be improved, which could lead to a simple and economically viable way to prepare solar cells. 

The scientists responsible for the research breakthrough, Mathew P. Genovese of the University of Waterloo in Canada, with Ian V. Lightcap and Prashant V. Kamat of the Radiation Laboratory and Department of Chemistry and Biochemistry at the University of Notre Dame in Indiana, will be publishing their study in an upcoming issue of the American Chemical Society's publication Nano. 

During an interview with Professor Kamat, John A. Zahm Professor of Science in Chemistry and Biochemistry and an investigator in Notre Dame's Center for Nano Science and Technology (NDnano) and who led the research, explained, "Quantum dots are semiconductor nanocrystals which exhibit size-dependent optical and electronic properties. In a quantum dot sensitized solar cell, the excitation of semiconductor quantum dot or semiconductor nanocrystal is followed by electron injection into TiO2 nanoparticles. These electrons are then transferred to the collecting electrode surface to generate photocurrent. 

The holes that remain in the semiconductor quantum dot are removed by a hole conductor or redox couple and are transported to a counter electrode. If we can optimize the paint preparation, it should be possible for anyone to open a bottle (or a can in the long run) and apply it to a conducting surface. This will decrease the variability between lab to lab or person to person as one encounters in a multi-step process. Having fewer fabrication steps and ambient preparative conditions should provide an economically viable transformative technology." 

During their research the scientists tested a number of different compounds, but found that a composite of mixed CdS/TiO2 and CdSe/TiO2 nanoparticles performed best, particularly when the CdS and CdSe was deposited directly on the TiO2 nanoparticles as a coating. 

Describing their work they said that the nanoparticles were suspended in a water-alcohol mixture to create the binder-free paste, which was then applied to conducting glass surface and annealed at 200 degrees Centigrade. When coated on a glass electrode, the paint has an overall power conversion efficiency exceeding 1 percent. Although some multifilm quantum dot solar cells have efficiencies greater than 5 percent, the scientists believe that using different quantum dots and further optimization could significantly increase the efficiency of the paint. 

Potential uses could include painting electronic devices such as cell phones to recharge their batteries, along with larger electrical devices such as computers, while rooftops, windows, and cars could be coated as well.  

The scientists' work has attracted some major governmental interest and the Department of Energy's Office of Basic Energy Sciences is funding their research. 

Professor Kamat concluded in a Notre Dame press release, "We want to do something transformative, to move beyond current silicon-based solar technology. The best light-to-energy conversion efficiency we've reached so far is one percent, which is well behind the usual 10 to 15 percent efficiency of commercial silicon solar cells. But this paint can be made cheaply and in large quantities. If we can improve the efficiency somewhat, we may be able to make a real difference in meeting energy needs in the future. That's why we've christened the new paint, Sun-Believable."

Pentagon acknowledges Iran downed U.S. stealth drone.

5 December 2011, 12:47 (GMT+04:00)
A U.S. surveillance drone that went missing last week in western Afghanistan appears to have crashed in Iran, in what may be the first case of such an aircraft ending up in the hands of an adversary, Washington Post reported.

Earlier it was reported, that Iran's Army shot down a remote-controlled reconnaissance drone operated by the US military in the eastern part of the country. Iran Army's electronic warfare unit successfully targeted the American-built RQ-170 Sentinel stealth aircraft after it crossed into Iranian airspace over the border with neighboring Afghanistan. The RQ-170 is a stealth unmanned aircraft designed and developed by Lockheed Martin Company. The US military and the CIA use the drone to launch missile strikes in Afghanistan and in Pakistan's northwestern tribal region.

On Thursday Iran's supreme leader warned Israel and the United States that Tehran's response will be tough should its archenemies choose a military strike against Iran over the country's controversial nuclear program.

U.S. officials acknowledged Sunday that a drone had been lost near the Iranian border, but they declined to say what kind of aircraft was missing.

The Iranian government has not released any pictures of the recovered aircraft, which they said was downed by defense forces after it flew across the border and into the country's airspace.

The unnamed Iranian military official said that "due to the clear border violation, the operational and electronic measures taken by the Islamic Republic of Iran's Armed Forces against invading aircraft will not remain limited to the Iran's borders."

U.S. officials cast doubt on this and other Iranian assertions. "We have no indication that it was brought down by hostile fire," said a senior Pentagon official, speaking on the condition of anonymity to discuss sensitive surveillance activity.

If an RQ-170 drone crashed in Iran, it would mark a significant setback for the U.S. military. The United States has lost less-sophisticated unmanned aircraft in recent years over Iran, but a nearly intact RQ-170 could offer a potential windfall of useful intelligence for the Iranians and their allies.

The aircraft has special coatings and a batwing-like shape that is designed to evade detection by enemy radar. The aircraft could help the Iranians better understand the vulnerabilities of U.S. stealth technology and provide them with clues on how to spot other aircraft, U.S. officials said.

The U.S. military released a short statement later Sunday on the missing drone. "The [unmanned aerial vehicle] to which the Iranians are referring may be a U.S. unarmed reconnaissance aircraft that had been flying a mission over western Afghanistan late last week," it said. "The operators of the UAV lost control of the aircraft and had been working to determine its status."
