Old School – Self Reliance 101 » Blog Archive » DIY–free, easy, clever
Today’s Old School lesson is a hands-on project: how to install a pour spout on a canning jar–great for dry cooking ingredients like sugar. This is the sort of DIY project Grandma could have really gotten into. It’s freeIt uses up things that would otherwise be thrown awayIt’s usefulIt’s easy and only takes a few minutes For this project, all you need is an empty salt carton, a mason canning jar with a screw band, and a sharp knife. Take an empty salt carton. CAREFULLY cut around the top of the carton by inserting a sharp knife straight down and moving around the top. The cut doesn’t need to be perfect and smooth…just do the best you can without drawing blood. Fill a canning jar with some dry, pourable substance like sugar. If you want to use a regular-mouth canning jar, use its lid (not the screwband) to trace a cutting circle onto the top of the salt carton. The Damsel is pretty excited about using this, since she keeps her sugar in a huge bin in the pantry.
The $300 House: A Hands-On Lab for Reverse Innovation? - Vijay Govindarajan
by Vijay Govindarajan | 12:07 PM August 26, 2010 Editor’s note: This post was written with Christian Sarkar, a marketing consultant who also works on environmental issues. David A. Smith, the founder of the Affordable Housing Institute (AHI) tells us that “markets alone will never satisfactorily house a nation’s poorest citizens…whether people buy or rent, housing is typically affordable to only half of the population.” The result? We started discussing the issue, examining the subject through the lens of reverse innovation. Here are five questions Christian and I asked ourselves: How can organic, self-built slums be turned into livable housing? Livable Housing. Look and Feel. In effect, the house is really a one-room shed designed around the family ecosystem, a lego-like aggregation of useful products that “bring good things to life” for the poor. World-Class Design. The Reverse Innovation Payoff. A House of One’s Own: Affordability. Of course, the idea we present here is an experiment.

The Vertical Farm Project - Agriculture for the 21st Century and Beyond | www.verticalfarm.com
The Problem By the year 2050, nearly 80% of the earth's population will reside in urban centers. Applying the most conservative estimates to current demographic trends, the human population will increase by about 3 billion people during the interim. An estimated 109 hectares of new land (about 20% more land than is represented by the country of Brazil) will be needed to grow enough food to feed them, if traditional farming practices continue as they are practiced today. At present, throughout the world, over 80% of the land that is suitable for raising crops is in use (sources: FAO and NASA). Historically, some 15% of that has been laid waste by poor management practices. A Potential Solution: Farm Vertically The concept of indoor farming is not new, since hothouse production of tomatoes, a wide variety of herbs, and other produce has been in vogue for some time. It took humans 10,000 years to learn how to grow most of the crops we now take for granted. Advantages of Vertical Farming
A Sea Change in Ocean Conservation | Conservation International Blog
A ship sailing near Alor, Indonesia. (© CI/ Photo by Sterling Zumbrunn) In my 36 years of work in conservation, I have never before witnessed as much attention and concern being paid to the deteriorating health of our oceans, and the resulting consequences of that deterioration for people everywhere. Ocean issues have grown from being a concern of environmental organizations to an urgent topic in corporate boardrooms and the offices of heads of state — an important shift in attitude that gives me reason for hope. From the World Economic Forum’s annual meeting in Davos in January to The Economist’s World Oceans Summit I attended last month in Singapore, the concerns are palpable. With the world’s population expected to grow to 9 billion people by 2050 — doubling the demand for food, energy and water — corporations and governments are looking to the oceans for answers.
