A vertical hidroponic garden for growing food on your windows.  If you’ve got tools, space, a little extra time, and a knack for building things, constructing your own windowfarm gives you additional control to customize the system for your own setup. You will need to register on the community site and accept community terms of service before accessing the plans.

This handmade kit creates a personal experience of participating in a productive food cycle. Human urine, the natural product of our bodies’ daily metabolism, is a sterile solution rich in excess nutrients. The kit lets you recycle the excess nutrients your body creates when you eat and drink into more life, locally. You can take this kit home, pee in it, and perform a biochemical reaction that transforms the nutrients in your urine into an immediately usable fertilizer to feed your own plants.

Ecotopia Biketour will be cycling through southern Europe this year, the project is being hosted by Research and Degrowth. This year’s theme is “towards degrowth” – challenging the growth mentality which currently dominates and overlooks real social and environmental values. We are an eco-mobile do-it-yourself activist community emerging every summer already for 20 years. We aim to learn from each other and local groups we visit, support their campaigns with creative ways. We carry all our equipment on bikes & trailers and make all the group decisions by consensus. A project for everyone interested in being part of a community and travelling without engines – the exact opposite of an all-inclusive flight to the beach!

My guide is different. I explain exactly what a kilowatt hour is and how much you pay for one. And I show you how to calculate exactly how much electricity your household appliances use, so you know which items are guzzling the most juice (and which ones are the best targets for savings). You’ll also learn exactly how to read your electric meter, if you like. (Find that on any other website.) And I not only give you meaningful tips for slashing your electricity consumption, I give you the tools to figure out exactly how much you’re saving as well. Finally, I’ve answered countless questions from readers about saving electricity. If you have a question, it’s probably answered here already.

Typical prices for bulk purchase of fuels at domestic or small commercial scale, February 2012 N.B. These prices are intended for guidance only and represent the typical cost per unit of fuel energy for comparison. This is not the same as cost per unit of delivered heat which will depend on the efficiency of the boiler or stove, and may also include other charges such as service and maintenance for heat supply contracts. All prices are prone to significant variation with geographical region, tariff choice, order quantities, overall contract size and duration, time of year, delivery distance and time, etc. Woodfuels in particular are available at prices both significantly above and below those quoted, and bulk prices will be subject to a minimum delivery size of perhaps 3-5 tonnes. Wood pellets bought in bags may be significantly more expensive than those bought in bulk.
