Countries With 100% Renewable Energy
Cahora Basso, Mozambique Which countries have the highest percentage of renewable energy – care to guess? I suspect that names like Germany, Denmark or Spain might spring to mind. They’re certainly making good progress, but they’ve got nothing on the world’s renewable energy leaders. There are countries in the world powered entirely by renewable energy, and some that are even net exporters of green electricity. These pioneers are overlooked for a variety of reasons. Most often its a matter of categorisation – what is and what isn’t considered renewable energy. Others simply leave hydro and geothermal out because they’re older technologies, and including them in renewable energy statistics might make people complacent about their percentages. Still, taking that broader perspective, here are some forgotten pioneers of the renewable energy world: Iceland – Built as it is on a volcano, Iceland has tapped the earth’s natural warmth to supply 85% of the country’s housing with heat.

Compressed Air Energy Storage from LightSail Could Run a Whole City
Clean Power Published on November 10th, 2012 | by Tina Casey The company LightSail Energy started out a few years ago with a student’s modest idea for a compressed air scooter, and now it has just raised $37.3 million in private funding to bring utility scale, compressed air energy storage to the market. The Compressed Air Conundrum As aptly described by writer Rachel Metz over at the MIT Technology Review, half of the compressed-air equation is simple enough from a clean energy perspective. The hard part kicks in when you try to store large quantities of compressed air. The Indian car manufacturer Tata Motors has apparently found at least a partial solution for small scale compressed air, but LightSail is going down an entirely different road. LightSail’s Compressed Air Solution Danielle Fong, Chief Scientist and co-founder of LightSail, is the former student who dreamed of a compressed-air scooter.

DIY Friendship Bracelet
For several months now, we’ve been receiving emails requesting a friendship bracelet DIY. Well, friends, ask and you shall receive! Today, we’ll give you a step by step tutorial on the classic chevron pattern. If you used to whip up friendship bracelets like a champ in grade school and have since forgotten how, consider this a refresher course. And if you can make these with your eyes closed and arms tied . . . umm, can we still be friends? You’ll need:embroidery threada safety pin or tapea pair of scissors Start by cutting several strands of embroidery thread at about 24 inches each. Start on the left side with the outermost color (shown here in red) and make a forward knot by creating a 4-shape over the 2nd color, loop it under and back through the opening. Pull up and to the right to tighten. Now pick up the outermost color on the right side (show here in red) and make a backward knot, creating a reverse 4-shape over the 2nd color, loop it under and back through the opening.

For buried wire, the wire at 60cm depth. Conduit encloses wire. Buried wire is surrounded by sand at 30cm around it. Trench is refilled with the native soil after completion. Metallic: Aluminum or rigid galvanized metal. Non-metallic: Wire material: copper vs aluminum. Copper is more conductive per unit volume but corrodes through. Aluminum is more conductive per unit mass and forms strong corrosion-resistant layer. Conventional: thermoplastics for heat and moisture protection.

Clean storage: These scientists are making an organic, water-based battery for the power grid
Most batteries — whether they’re embedded in your iPhone or they’re plugged into the power grid somewhere — use some kind of metal to create the chemical reaction that stores the energy. In laptops and Teslas, that metal is lithium; in traditional cars it’s lead. But researchers at University of Southern California are developing an all-organic, water-based battery that can be entirely synthesized (not using materials mined from the earth) and uses no metals or toxic chemicals. USC chemistry professor Sri Narayan told me he thinks that in the future, when batteries are scaled up to the point where they’re commonly used on the power grid at large sizes, then using metals and toxic chemicals in them will be a big problem. USC research on an organic flow battery. Batteries that use naturally occurring water and organic molecules could also be less expensive than comparable batteries that use rare or expensive metals. USC Post Doctorate Bo Yang working on the organic flow battery.
