Hydropower from Reuse Reused: a small stepper motor as found in a printer 2 discarded CD-ROMs a foam tray some long stick (I used a piece of 20mm diameter PVC tube from demolition) a LED one or two tie-wraps a small piece of scrap paper Non-reused: The only non-reused part is the hot melt glue (I recommend the low temp type, especially when working with kids). Tools: scissors, screwdriver to disassemble the printer (not shown), cutting pliers or desoldering tools for (optional, not shown). With a bit of luck the LED can also be found in the discarded printer. With even more luck you can find some discarded electronics with a LED standing tall on a printed circuit board, with most of its legs still intact, instead of mounted flush on the board. To keep within the spirit, you can also reuse tie-wraps: when you cut them loose carefully near the “ratchet”, you end up with a shorter, but still usable tie wrap. Now to start building, see the next step.
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. 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. Power the results The battery now needs to be charged up with a 120-volt power supply.
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?" 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. My own appreciation for organic agriculture dates to a conversation that I had years ago with a cotton grower from the Central Valley of California who told me about his switch from conventional to organic growing. No surprise there.
…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. Strengthen the voice of CSOs to demand accountability; 2. 3. 4. 5. 6. 7. The above lists are my dream for Green Economy for Sustainable Development in Nigeria.

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. 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.

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. They come in all shapes and sizes and we couldn't help but share them. 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 Pink Fairy Armadillo
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. 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. Evergreen works from over a 100 bases and employees 4,500 people. Evergreen was given a no contest bid that gave them all the facilities in Marana, Arizona that previously belonged to CIA’s Air America (Pinal Air Park, Arizona). Was John P. Source
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. 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. Chemicals, he said, were being utilized as part of the development of a new radar system at Wright-Patterson Air Force Base in Dayton, Ohio. The rally will be attended by hundreds of people from across the nation who are concerned about these poisons being dumped out of the sky onto millions of people on the ground. Many believed the phenomena were created at the Air Force laboratory.
Aspartame is, by far, the most dangerous substance on the market that is added to foods. Aspartame is the technical name for the brand names NutraSweet, Equal, Spoonful, and Equal-Measure. It was discovered by accident in 1965 when James Schlatter, a chemist of G.D. Searle Company, was testing an anti-ulcer drug. Aspartame was approved for dry goods in 1981 and for carbonated beverages in 1983. What Is Aspartame Made Of? Aspartic Acid (40 percent of Aspartame) Dr. How Aspartate (and Glutamate) Cause Damage Aspartate and glutamate act as neurotransmitters in the brain by facilitating the transmission of information from neuron to neuron. The risk to infants, children, pregnant women, the elderly and persons with certain chronic health problems from excitotoxins are great. "It is prudent to avoid the use of dietary supplements of L-glutamic acid by pregnant women, infants, and children. One common complaint of persons suffering from the effect of aspartame is memory loss. Phenylalanine (50 percent of aspartame) Phenylalanine is an amino acid normally found in the brain. "...
