This Bamboo Scooter Runs On Nothing But Air Forget gas, now a scooter exists that is designed to run on nothing but air. Specifically, compressed air, the same stuff that’s used to clean computer keyboards, fill scuba tanks, fire paintball guns, and more recently, to power cars. Like an electric scooter, the Ecomoto is quiet, doesn’t pump pollution into the atmosphere, and if the air compressor used to fill its tank runs on renewable electricity, doesn’t have much of a carbon footprint. The New Geopolitics of Food - By Lester R. Brown In the United States, when world wheat prices rise by 75 percent, as they have over the last year, it means the difference between a $2 loaf of bread and a loaf costing maybe $2.10. If, however, you live in New Delhi, those skyrocketing costs really matter: A doubling in the world price of wheat actually means that the wheat you carry home from the market to hand-grind into flour for chapatis costs twice as much. And the same is true with rice. If the world price of rice doubles, so does the price of rice in your neighborhood market in Jakarta. And so does the cost of the bowl of boiled rice on an Indonesian family's dinner table.

3D solar panels can produce 20 times more energy than flat panels We see the trend in 3D technology everywhere: Movie theaters, home theaters, game consoles, 3D printers. But researchers at Massachusetts Institute of Technology recently discovered that creating a 3D-inspired solar panel not only help to keep up with the trends, it could draw in 20 times more energy than flat panel designs. Traditional solar panels lay flat on a surface or rooftop, facing the sun to collect energy. MIT researchers decided to change the shape of solar panels, conducting experiments with a cube, tall cube, and tower-shaped panels to see which design brought in more energy. Compared to flat panels, all three 3D panels created impressive results and outproduced traditional panels, with the accordion-style tower drawing in 20 times more power per square foot.

World's First Known Magnetic Cellulose Loudspeakers: Potential for Magnetic Cellulose Comes in Crisp and Clear World's First Known Magnetic Cellulose Loudspeakers: Potential for Magnetic Cellulose Comes in Crisp and Nov. 20, 2013 — They're flat, ultra-thin and great-sounding. The world's first known magnetic cellulose loudspeakers have been demonstrated at KTH. Throughout the ages, Swedes have relied on their country's vast forests as a source of sustenance and economic growth. Now add the world's first magnetic cellulose membrane loudspeakers to the list of products that can be produced from wood. These flat, sonorous and environmentally-friendly speakers are made with a new material derived from wood pulp -- magnetic cellulose gel -- which was developed at Stockholm's KTH Royal Institute of Technology.

OECD calls for policy reform and technology to prevent impending water crisis The OECD has released a report outlining the challenges humanity faces to maintain water resources in the future (Photo: Shutterstock) Image Gallery (2 images) Worldwide population growth and the related rapid increase in urbanization is already posing problems in many areas for the management of that most precious of resources, water. With these problems only set to intensify, the Organization for Economic Co-Operation and Development (OECD) has released a report outlining the challenges humanity faces to maintain water resources in the face of demographic growth and climate change. Called Meeting the Water Reform Challenge, the report says that urgent reform of water policies is crucial in order to preserve human and environmental health as well as economic growth.

Nanotubes boost potential of salinity power as a renewable energy source In November 2009, Norwegian state owned electricity company Statkraft opened the world’s first osmotic power plant prototype, which generates electricity from the difference in the salt concentration between river water and sea water. While osmotic power is a clean, renewable energy source, its commercial use has been limited due to the low generating capacities offered by current technology – the Statkraft plant, for example, has a capacity of about 4 kW. Now researchers have discovered a new way to harness osmotic power that they claim would enable a 1 m2 (10.7 sq. ft.) membrane to have the same 4 kW capacity as the entire Statkraft plant. The global osmotic, or salinity gradient, power capacity, which is concentrated at the mouths of rivers, is estimated by Statkraft to be in the region of 1,600 to 1,700 TWh annually. The Statkraft prototype plant (and a planned 2 MW pilot facility) relies on the first method, using a polymide membrane that is able to produce 1 W/m2 of membrane.

Permaculture: Creating Sustainable Systems Permaculture is a design science based on the observation of natural systems. It helps us realise an ethical approach for creating ecological systems for sustainability in all aspects of our lives. It involves creating forest food gardens; planting and maintaining both non-edible and edible plants such as vegetables, fruits, herbs, nuts, berries and grain. Along with keeping and breeding animals, eliminating the need for herbicide, catching and reusing rainwater; creating swales, soil creation, local economics, preventing pests and diseases, reducing waste and creating energy and community systems.

-New HOme Project « Leifur Thor’s WorldPress Station Imagine a home that provides a level of comfort and ease of living beyond what’s known. Now imagine this home uses less energy while providing that superior standard of living. In this century, wouldn’t we rather have a home that harvests energy quietly instead of using it? An enclosed space three average people with no special skills can assemble noise free, and with no special building tools in three weeks from start to finish. With over 10,000 variations for layout a home we can alter in a day without need of a contractor.

A Urine Powered Generator : Maker Faire Africa Posted on Tuesday, November 6, 2012 · 168 Comments Possibly one of the more unexpected products at Maker Faire Africa this year in Lagos is a urine powered generator, created by four girls. The girls are Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15). 1 Liter of urine gives you 6 hours of electricity. The system works like this: Aquaponics and Vertical Farming. Aquaponics is a sustainable, closed-loop food production system that combines traditional aquaculture (breeding/keeping fish) with hydroponics (growing plants without the use of soil) using an eco-system approach within a symbiotic environment. The by-products from the fish get broken down by beneficial bacteria into nutrients. The waste water is then pumped up/upcycled as an organic fertilizer for the plants in the hydroponic sub-system. The plants take up the nutrients whilst also cleaning the water – which is then recirculated back down for the fish. Aquaponics is about recycling wastes into resources, combining technologies, creating eco-systems, promoting biodiversity and producing food.
