How to make batteries out of paint This article was taken from the January 2013 issue of Wired magazine. Be the first to read Wired's articles in print before they're posted online, and get your hands on loads of additional content by subscribing online. Researchers at Rice University, Houston, have created a battery made of paint. "We've airbrushed it on to tiles, polymers, glass and steel," says grad student Neelam Singh. Here's how to harness the power of art. Assemble your paintbox Your paintable lithium-ion battery comprises five coats of paint, each representing a component of the battery: the lithium-titanium anode, two current-collectors made of a solvent, a cobalt cathode, and a polymer separator that holds the electrolyte. Layer the components The paints have to be applied in a certain order: the separator is in the centre, between the anode and cathode, and the two current collectors seal the sandwich. Seal them up tightly To seal the battery, you can use the aluminium foil found in coffee-sachet packaging.
How I built an electricity producing wind turbine Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. I found a great piece of property. The problem is, it's so remote that there is no electric service available. That's not really a problem. No electricity equals no light pollution. One thing I noticed right away about my property is that most of the time, the wind is blowing. Let me state up front that I probably won't be able to help you out much if you decide to build your own wind turbine. Since no one seems to be reading the FAQ, I will answer the No. 1 question I get many, many times a day right here up front. Update: Here is a video of the wind turbine in operation. Update: Here is a video of me assembling and setting up the wind turbine on my remote off-grid property. I started the process of designing my wind turbine by Googling for information on home-built wind turbines. .
Only Organics Can Feed the Hungry World: Here's Why Students working on UGA's organic demonstration farm in summer 2012. (Photo: UGA College of Ag)A new approach to agriculture that combines the best in industrial production with organic and sustainable practices is the key to meeting the changing needs of a changing world, where resources are rapidly depleted by a growing population. "Are Organic Foods Safer or Healthier Than Conventional Alternatives?" is the title of a controversial report released last week by Stanford University's Center For Health Policy. The study concludes that there is "little evidence of health benefit" from eating organic food." The press weighed in with a bewildering range of instant reactions. The LA Times, on the other hand, pointed out in an editorial that the study largely ignored the ill effects of pesticide residues on conventionally-grown produce, and the hormones and antibiotic-resistant bacteria that taint factory-farmed meat and poultry. No surprise there. Modern agriculture is here to stay.
Peak Opportunities …7 POINTS AGENDA ON GREEN ECONOMY FOR SUSTAINABLE DEVELOPMENT | I SEE A CHANGE Nigeria has been largely unfortunate not to have good and progressive political leaders, and this has resulted in perpetuating Nigeria in poverty and underdevelopment despite her huge GREEN ECONOMY. This persistent failure of the Nigeria System has produced a large army of bitter critics, who consistently point out the ills in the Governance of Nigeria and potter alternative ways of doing it better. Toward the Sustainable Development Conference [RIO+20] in Brazil. My 7 point agenda on green economy for sustainable development which I recommend for the President to look into will be: 1. 2. 3. 4. 5. 6. 7. The above lists are my dream for Green Economy for Sustainable Development in Nigeria.

The Problem of Growth That source is the hierarchal structure of human civilization. Hierarchy demands growth. Growth is a result of dependency. The solution to the problem of growth, then, is the elimination of dependency. I. Why must hierarchy continually grow and intensify? Human Psychology Drives Growth Humans fear uncertainty, and this uncertainty drives growth. One of the seeds of hierarchy is the desire to join a redistribution network to help people through bad times—crop failures, drought, etc. Still today, our fear of uncertainty and desire for stability and security create an imperative for growth. The Structure of Human Society Selects for Growth The psychological impetus toward growth results in what I consider the greatest growth-creating mechanism in human history: the peer-polity system. In a peer-polity system, where many separate groups interact, it was not possible to opt-out of the competition to create more surplus. The Development of Modern Economics & Finance Requires Growth II. III.
The Most Incredible 3-D Printed Things We’ve Ever Seen ⚙ Co The levees have broken for 3-D printing, and the resulting deluge of printing-concepts-on-the-cheap is flowing faster than we can gather. The best of these rise to the surface for their innovating predictions of a faster/safer/healthier future. A Robotic Hand That Doesn’t Cost An Arm And A Leg Teen engineer Easton LaChappelle created his first robotic hand out of Legos, fishing wire, and surgical tubing--a feat that earned him 3rd place at the Colorado Science Fair. More importantly, it introduced him to a young girl who was born without an arm and needs new prostheses as she grows, which cost a hefty $80,000 per arm. Speaking at TEDxMileHigh last month, LaChappelle presented the arm, which features as much motion and almost as much strength as a human arm and costs just $400.

Installing a Solar Energy System Like many of you reading this article, I am fairly new to the realization that our future may not turn out the way we originally planned. A little over two years ago, after the financial turmoil set in, I began to wake up from my comfortable, relatively uncomplicated life and take a closer look at what was going on around me. I was first introduced to the Crash Course by an attendee at the 2009 CPAC Liberty Forum in Washington, DC where I had gone to hear Ron Paul speak. Little did I know how dramatic an impact that one conversation would have on my life. I hope reading about the thermal and photovoltaic solar systems we have installed will encourage you to think about actions you can take to prepare for our uncertain future. Our House – NOT a Model of Sustainability I think it is important for you to know the environment and initial problem in order to make sense of some of the design/implementation decisions we have made.

Real Animals That You Didn't Know Existed Maned Wolf The world we live in is filled with exotic wildlife, and that means more than just lions and giraffes. There are a multitude of species that are lesser known to the general public and fascinating to learn more about. Redditor preggit decided to introduce a whole batch of these real animals that look like they've been Photoshopped. One animal that preggit features is the maned wolf, which looks like it's a red fox that mated with a deer to create a furry, lovable face with long, slender legs, but is actually its own type of mammal. Top photo: The maned wolf is the largest canid in South America, resembling a large fox with reddish fur. Fossa The fossa is cat-like, carnivorous mammal that is endemic to Madagascar. Barbirusa Babirusa, meaning "Hog-deer," are members of the pig family found in Wallacea, or specifically the Indonesian islands of Sulawesi, Togian, Sula and Buru. Zebra Duiker The zebra duiker is a small antelope found in the Ivory Coast and other parts of Africa. Dhole
Solar panels could destroy U.S. utilities, according to U.S. utilities Solar power and other distributed renewable energy technologies could lay waste to U.S. power utilities and burn the utility business model, which has remained virtually unchanged for a century, to the ground. That is not wild-eyed hippie talk. It is the assessment of the utilities themselves. Back in January, the Edison Electric Institute — the (typically stodgy and backward-looking) trade group of U.S. investor-owned utilities — released a report [PDF] that, as far as I can tell, went almost entirely without notice in the press. That’s a shame. It is one of the most prescient and brutally frank things I’ve ever read about the power sector. I’ve been thinking about how to convey to you, normal people with healthy social lives and no time to ponder the byzantine nature of the power industry, just what a big deal the coming changes are. So, just a bit of background. This complexity makes it difficult to generalize about utilities … or to discuss them without putting people to sleep.
Evergreen CIA Owned Airline: Dropping Poison On You And Your Family [Besides this outfit, it is reported that chemtrail planes also fly out of US and other NATO military bases in the US and around the world.] Evergreen Air is a CIA front company for chemtrail operations within the US, based out of Marana Air Park near Tucson Arizona and McMinville Oregon, near Portland. A major missing piece of a grand conspiracy has been targeted by a drunk pilot. In a small town 30 miles east of the Pacific Ocean in Oregon is the center of a major global operation. At a bar in McMinnville, Oregon, an inebriated pilot attempted to impress one of the pretty ladies with tales of his secret mission. The pilot’s pathetic attempt to portray himself as a Sean Connery or Daniel Craig caused him to (ante up) his importance and spill the secrets of the CIA’s asset Evergreen International Aviation. The slurred revelations confirmed suspicions that Evergreen (International Aviation) is part of the major crap dump on the planet. Was John P. Source
Could New York run on renewable energy alone? Three times now, Mark Jacobson has gone out on the same limb. In 2009 he and co-author Mark Delucchi published a cover story in Scientific American that showed how the entire world could get all of its energy — fuel as well as electricity — from wind, water and solar sources by 2030. No coal or oil, no nuclear or natural gas. New York state could end fossil fuel use and generate all of its energy from wind, water and solar power, according to Mark Jacobson. [An edited transcript of the interview follows.] At first glance, your proposals to convert society wholesale to renewable energy, and relatively soon, sound wild. Mostly, it’s pretty positive. Why did you dive down into New York state after having done the entire world? To get any traction I figured we had to do a plan with higher resolution, because otherwise it’s just too massive for anyone to actually do anything about it. The main obstacles are political and social — getting politicians onboard. So then how do you sell the plan?
Military Behind 4 Different Chemtrail Programs by Mike Blair 21 June 2001 from Rense Website Just what exactly are those mysterious airplane vapor trails seen filling America's (and Canada's) skies? A group of independent investigators may have the answer. In a series of high-tech programs that would enthrall the most dedicated science fiction fans, the military is producing what have become known as "chemtrails" - the thick, viscous airplane engine trails that have been poisoning the air and ground with toxic chemicals. These "tracks" in the skies, believed to be left by a combination of military and civilian aircraft drawn into the massive, multi-billion dollar program, are unlike regular high-flying aircraft's vapor trails. The principal chemical being deposited in the air consists of various mixtures of barium salts, which were revealed in studies undertaken by a Pennsylvania-based high-tech weapons scientist. In 1982, the air base was closed down and the top secret laboratory was the only Air Force facility retained.
