The Beginning Farmer’s Guide to Self-Sufficiency It’s a dream that many hold dear to their hearts but few will ever get to experience: a farm of one’s own. Not just any sort of farm, either, but a self-sufficient one running on nothing but the American Dream and a whole lot of elbow grease; the last bastion of a an era gone by in a world overrun with consumerism and identical globs of prepackaged food-like product lining the shelves of our local supermarkets. How does a beginning farmer become an island of sustainability and self-reliance in a cultural sea dependent on cheap fuel and chemical inputs? The list of possibilities might seem daunting—solar panels, home-grown animal feed, a farm truck that runs on biodiesel … where does it end?

Amazing ERO Concrete-Recycling Robot Can Erase Entire Buildings Demolition is a messy business—not only does the process require heavy machinery and produce clouds of dust, but it also results in giant piles of rubble that often head straight for the landfill. Omer Haciomeroglu, a student at Sweden’s Umeå Institute of Design has designed Ero – a robot that recycles concrete in an energy-efficient manner and separates it from rebar and other debris on the spot. The project won the 2013 International Design Excellence Award (IDEA) in the Student Designs category. Heavy machines used in demolition consume large amounts of energy in order to crush concrete walls into small pieces, not to mention that demolition processes have to be accompanied by large amounts of water sprayed onto the structures to prevent the spread of dust. Once the work is done, the rubble is transported to recycle stations where waste is separated manually. Power crushers are used to pulverize the concrete and the metal is melted for reuse.

How To Build A 5 Gallon Bucket Hydroelectric Generator With self-sufficiency on the rise in almost every large city, it is common to see people trying to set up their own power or water supply. Recycling is almost a regular thing now so those who want to live really independently choose a hydroelectric generator as their next DIY project to make. Making such a system is quite easy and actually there is no need for a bunch of extra materials to get in order to begin the whole construction phase. A 5-gallon bucket should be your base and the rest will easily fall into place.

Unwrapping the Gift Economy It has become popular to declare that we need to move to a gift economy, in which we share more freely and value community more deeply, and in which our relationships are less often money-based and transactional. Clearly, this is an important and appealing proposition. But there’s far more wrapped up in the concept than it may appear. To get to “the more beautiful world our hearts tell us is possible,” as Charles Eisenstein so eloquently implores, we’ll need to understand the full implications - and possibilities - behind the concept. Often, the argument in favor of a gift economy begins with reference to its historical origins in hunter-gatherer societies. What is also needed is a full understanding of (1) why those societies were based on sharing and community, (2) why ours is not, and (3) what exactly we need to bring forward from the past if we want to have what they had, even in today’s vastly more complex reality.

OpenFarm's community-created guides help you learn to grow anything Backyard gardens and home-scale farms are popping up all over the world as people re-develop an interest in cultivating their own food, but gardening newbies can get a bit lost at times. While the ideal situation would be to learn alongside a seasoned gardener, most folks turn to the web for helpful tips and tricks. OpenFarm is a new open-source platform in which people can create guides to help others with their food-growing attempts, and can learn new info that others have shared.

It can be used to heat water, and cut the cost of bills. Composte and warmth go hand in hand.

Clothes Dryer of the Future Uses Vibrations, Not Heat Scientists at Tennessee’s Oak Ridge National Laboratory have developed a “dryer of the future” that uses high-frequency vibrations instead of heat to extract moisture from clothes. Compared with traditional tumble dryers, which can consume as much energy as a refrigerator, clothes washer, and dishwasher combined, according to the Natural Resources Defense Council, the newfangled process significantly reduces drying time and energy use. Ayyoub M. Momen, the research engineer spearheading the project, said his invention was inspired by commercial humidifiers that use ultrasonic transducers to convert water into tiny droplets, creating a cool mist.

Inexperienced Guy Builds Cool Mini Camper Experience is no substitute for enthusiasm it seems, as proven by this novice builder. It took approximately 60 days for this guy to build this cool mini camper. It turned out so well that you would never guess that it was built by someone with almost no building experience at all! The first thing that he did was to buy a trailer that was suitable for the intended purpose. He began building from the bottom up in order to ensure that he could properly insulate the camper. The sides were cut out in the desired shape, not cut out to fit frames. The Rise of the Sharing Communities Creative Commons photo by Lobkovs As the sharing economy picks up momentum, its reach has become global. In cities and towns around the world, people are creating ways to share everything from baby clothes to boats, hardware to vacation homes. There are also groups emerging that consciously identify with the big-picture sharing movement. These groups focus on education, action and community-building, and advocate for a cultural shift toward widespread sharing.
