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.

POPSFLOW: Documentary humanizes international water politics Please join me along with the directors urge to viewers to sign the UN petition http://article31.org/ that would make access to clean drinking water a basic human right. The director wants you to think of water as a commodity that's as precious as oil--blue gold, as they say. "Blue Gold" is also the title of a book by Maude Barlow, an activist who is featured in the film, fighting against the corporate takeover of water systems. Whoever controls water, has power. Though our tap water is pretty regulated, we insist on buying bottled water (in one particularly troubling tale, Nestle is selling Michigan water back to citizens of the state in bottles for a fee). Barlow says California has 20 years of water left, Arizona has 10 (but with the way they're building golf courses, she says, they could reduce it to five). Until then, don't forget to turn off the faucet when brushing your teeth.

POPSExploding hot water heater.Mythbusters Mythbusters Funny clip Steam Power Submitted by DoctorK on Sun, 10/26/2008 - 10:51am. One of the Mythbusters shows looked at the risk of exploding water heaters. By disabling the safety valve, they got dramatic explosions, with the internal tank flying hundreds of feet in the air. Very impressive in ultra slow motion, it motivated me to (safely) flush my water heater and check the functioning of the relief valve.

POPSPurified urine to be astronauts' drinking water I thought there was a problem with purification processes not being able to eliminate hormones. On a lighter side, if they practised a certain form of yoga, they would not have to purify all of it, just keep their own for cortisone.

POPSBefore & Now! Leave? BEFORE: free healthcare, free education, better electricity and water services, security of law and order INVASION: No health, little education, power by the hour, some water, no law, no order. US; 4,000 dead military plus 10s of 1,000 of broken in mind and body. Iraq; 100,000 dead, displaced? Both America and Iraq broken for how long? Why again? WMD? Oil? Israel? Democracy? Regime change? Why not a Mossad assassins bullet if Saddam was ever the problem? CIA had no qualms before although Castro shows their incompetence at illegal regime change.

POPS Baby Pygmy Hippo Brings New Hope For The Endangered Species ‘We would obviously have wanted her mother to raise her, but she definitely would have died if we didn't step in.’ She weighs 3.8 kg or 8.3 lbs. (the weight of a gallon of water) Pygmy hippos are reclusive and nocturnal. Along with their much larger cousins, the common hippopotamuses, they are the only hippo species in the world. Pygmy hippos are semi-aquatic and need to live near water to keep their skin moisturised and their body cool. They sometimes even mate and give birth in water. Pygmy hippos are plant-eating mammals, feeding on ferns, broad-leaved plants, grasses and fruits they find in the forest.

POPSFollowing The Trail Of Toxic E-Waste
This is smuggling. This is illegal," says Jim Puckett, founder of the Basel Action Network, a group working to stop the dumping of toxic materials in poor countries that certifies ethical e-waste recyclers in the United States. "A lot of people are turning a blind eye here. And if somebody makes enough noise, they're afraid this is all going to dry up." E-waste workers in Guiyu, China, where Pelley's team videotaped, put up with the dangerous conditions for the $8 a day the job pays. They use caustic chemicals and burn the plastic parts to get at the valuable components, often releasing toxins that they not only inhale, but release into the air, the ground and the water. Potable water must now be trucked into Guiyu and scientists have discovered that the city has the highest levels of cancer-causing dioxins in the world. Pregnancies in Guiyu are six times more likely to result in miscarriages, and seven out of 10 children there have too much lead in their blood. Allen Hershkowitz

POPSIce-Age Rhino remains found in UK Emelia, who wants to become a palaeontologist, had joined the fossil hunt for the first time. It was organised by the Cotswold Water Park Society and led by Swindon palaeontologist Dr Neville Hollingworth who also found the remains of a woolly rhinoceros in a gravel pit near Swindon in 2004

POPSTomorrow I start the best job in the world. I worked as a teacher for 14 years at Grangewood School (a wonderful little special school) until alcohol started ruining my life. Now eight years on and six months sober I am returning in a different capacity; as an intervenor for a lovely six year old lad who is deaf-blind and mentally impaired. I can't wait to get started. :-)

POPSSustainable Prefab Homes in Turkey Sustainable Prefabs from Orca Yapı: a steel-structured prefabricated home unit that could endure temperatures ranging from plus 50 degrees to minus 50 degrees Celsius, durable in earthquakes reaching 7.5 on the Richter scale, that is cheap to make "The baseline cost for a unit, which does not include any alternative energy production methods like the active solar power water heating system that is installed on the show model in Kocaeli, is $295 per square meter... 10 times cheaper than comparable units."
