POPSSun + Water = Fuel Michael Grätzel, however, may have a clever way to turn Nocera's discovery to practical use. A professor of chemistry and chemical engineering at the École Polytechnique Fédérale in Lausanne, Switzerland, he was one of the first people Nocera told about his new catalyst. "He was so excited," Grätzel says. "He took me to a restaurant and bought a tremendously expensive bottle of wine." In 1991, Grätzel invented a promising new type of solar cell. It uses a dye containing ruthenium, which acts much like the chlorophyll in a plant, absorbing light and releasing electrons. In Grätzel's solar cell, however, the electrons don't set off a water-splitting reaction. Instead, they're collected by a film of titanium dioxide and directed through an external circuit, generating electricity. Grätzel now thinks that he can integrate his solar cell and Nocera's catalyst into a single device that captures the energy from sunlight and uses it to split water.

POPSA Diamond Bigger than Earth Discovered The diamond is actually the crystallized interior of a white dwarf – or the hot core of a star that is left over after the star uses up its nuclear fuel and dies. It is made mostly of carbon and is coated by a thin layer of hydrogen and helium gases.

POPSPhysicist Claims First Real Demonstration of Cold Fusion "Arata and Zhang demonstrated very successfully the generation of continuous excess energy from ZrO2-nano-Pd sample powders under D2 gas charging and generation of helium-4," Takahashi told New Energy Times. "The demonstrated live data looked just like data they reported in their published papers . This demonstration showed that the method is highly reproducible."

POPSScientists find bugs that eat waste and excrete petrol “Our plan is to have a demonstration-scale plant operational by 2010 and, in parallel, we’ll be working on the design and construction of a commercial-scale facility to open in 2011,” says Mr Pal, adding that if LS9 used Brazilian sugar cane as its feedstock, its fuel would probably cost about $50 a barrel.

POPS0.3% of Saharan Sun Enough To Power Europe The visionary proposal comes as the Joint Research Centre of the European Commission released its strategic energy technology plan which highlighted photovoltaic cells as one of the eight technologies that need to be developed in the future. The plan also includes fuel cells, hydrogen, clean coal, second generation biofuels, nuclear fusion, wind and smart grids.

POPSGrand Illusion!!! The Mystery Crash
courtesy of Luxman, Luxenbourg. Hunt the Boeing! And test your perceptions! As everyone knows, on 11 September, less than an hour after the attack on the World Trade Centre, an airplane collided with the Pentagon. The Associated Press first reported that a booby-trapped truck had caused the explosion. The Pentagon quickly denied this. The official US government version of events still holds. Here's a little game for you: Take a look at these photographs and try to find evidence to corroborate the official version. It's up to you to Hunt the Boeing! Did you find the Boeing? Can you still defend the official version of events? > Well done! Remember to get in touch with master of illusion, David Copperfield. He'll be glad to hear from you! You found the official version lacking in something (like a Boeing, for example): > If you begin to question whether a Boeing really did crash on the Pentagon then, no doubt, you'll be wondering what happened to the aircraft that disappeared

POPSFour Reasons Not to Give Up on Interstellar Travel It looks far, dark, and cold... Yet, 120 years ago, flight was science fiction as well. C. G. Jung said that all dreams of space travel are just an escape from one most difficult challenge of all, that is the journey to man's inner space. :-) ...and see my clip from last week on suggested FTL drive. It seems the motivation to escape an inner journey just grows.

POPSPaper Bags or Plastic Bags? Everything You Need to Know So, while it's good to have the alternative (and to recognize the innovation it represents), bioplastics aren't quite ready to save us from the paper or plastic debate. Paper bags or plastic bags: the conclusion Both paper and plastic bags require lots and lots of resources and energy, and proper recycling requires due diligence from both consumer and municipal waste collector or private recycling company, so there are a lot of variables that can lead to low recycling rates. Ultimately, neither paper nor plastic bags are the best choice; we think choosing reusable canvas bags instead is the way to go. From an energy standpoint, according to this Australian study, canvas bags are 14 times better than plastic bags and 39 times better than paper bags, assuming that canvas bags get a good workout and are used 500 times during their life cycle. Happy shopping!

POPS"World needs a vacation from USA" He called for immediate technology transfer from the West to the Third World, to allow development based on clean technology — stressing the need to “reject intellectual property rights”. funds should not be distributed through the World Bank, which was trying to regain legitimacy by portraying itself as a “climate bank” while continuing to push fossil-fuel-driven development. Confronting global poverty and climate change means confronting US power. “I don’t think the world needs US leadership”, he said. “They should be more humble.” Whether the US achieves its goals “is where we, as civil society come in”, Bello said, suggesting that, by making intervention costly for the US, civil society could encourage a “new US isolationism”. The struggle is, he stressed, global. “The world needs a vacation from the messaianism of the US … A few decades of a self-absorbed US would be very good for the world.”

POPSOne hundred tesla without self-destructing Why would anyone need a magnet that strong? Greg Boebinger, director of the Magnet Lab, says that this magnetic field strength is the only way to test the properties of newly discovered high-temperature superconductors like iron oxyarsenide, which may improve the performance of MRI machines and high-voltage power lines while lowering their cost. A 100‑T magnet would also let you conduct certain zero-gravity experiments without traveling into space and let you develop magnetic propulsion systems that could eventually replace those that burn rocket fuel.
