A Solar Grill Prototype for a Greener Tomorrow Students at MIT are working on a case study for a new type of solar powered outdoor grill. Based on the technology from MIT professor David Wilson, this grill would collect thermal energy from the sun and store it to allow cooking times for up to twenty five hours at temperatures above 450 degrees Fahrenheit. The study is being conducted by Derek Ham, Eric Uva, and Theodora Vardouli, all part of an entrepreneurship course called “iTeams.” Meet Jordan's New Greenhouse-Power Plant Hybrid A novel combination of technologies that has the potential to turn large areas of desert green, producing commercial quantities of food and energy crops, fresh water, and electricity, looks set to have its first large-scale demonstration in Jordan. The governments of Jordan and Norway today inked an agreement to work with the Sahara Forest Project (SFP), an environmental technology group based in Norway, to build a 20-hectare demonstration center near Aqaba on the Red Sea, which would begin operation in 2015. "It's a holistic approach that could be of major interest to a large number of countries," says Petter Ølberg, Norway's ambassador to Jordan.
Green Energy "Oasis" to Bloom in the Desert? A renewable-energy "oasis" slated to be built in 2010 may serve as a proving ground for new technologies designed to bring green living to the desert. The planned research center is part of the Sahara Forest Project—but that doesn't mean it'll be built in Africa. Sahara means "desert" in Arabic, and the center is meant to be a small-scale version of massive green complexes that project managers hope to build in deserts around the globe. (See pictures of the planned Sahara Forest Project reseach center.)
How Big a Backyard Would You Need to Live Off the Land? posted by Dave Llorens on January 4th, 2011 What’s One Block Off the Grid? One Block Off the Grid makes it easier and more affordable for homeowners to go solar by negotiating great solar deals on their behalf. Since 2008, One Block Off the Grid has hosted hundreds of deals on solar in over 40 U.S. states and helped thousands of homeowners go solar. Seawater Greenhouse A seawater greenhouse is a greenhouse structure that enables the growth of crops in arid regions, using seawater and solar energy. The technique involves pumping seawater (or allowing it to gravitate if below sea level) to an arid location and then subjecting it to two processes: first, it is used to humidify and cool the air, and second, it is evaporated by solar heating and distilled to produce fresh water. Finally, the remaining humidified air is expelled from the greenhouse and used to improve growing conditions for outdoor plants. The technology was introduced by British inventor Charlie Paton in the early 1990s and is being developed by his UK company Seawater Greenhouse Ltd. The more concentrated salt water may either be further evaporated for the production of salt and other elements, or discharged back to the sea.
Help Build A Sustainable Off-Grid Friggebod With Floda31 It must be nice to be former Swedish housing minister Birgit Friggebo; She is now immortalized for her removing of the requirement for building approval for structures under 150 square feet, known forever as Friggebods, a portmanteau of her name and bod, or shed. It led to an explosion of innovative design and opportunity for young architects and designers. At Floda31, "a laboratory for innovation and creativity", Marije de Haas and Richard Holland and their students are building a Friggebodar, a" completely sustainable off-grid mini-house that can function at a climate ranging from +30C to -30C. " It's made of my favourite materiel-du-jour, Cross laminated timber. Floda31 Friggebodar from Marije de Haas on Vimeo. They are trying to raise money to build the little gem on IndieGoGo, explaining what we will all get for our support:
Mission 2014: Feeding the World Problem Seawater farming addresses the severe lack of freshwater and undesirable soil conditions for agricultural activities in coastal regions. Saltwater, instead of freshwater, can be used to directly support a wide range of sustainable agricultural activities and enrich the soils in the coastal regions. Freshwater, which is defined by having much lower salts and ions concentration than seawater and brackish water, only composes about 2.75% out of all water on Earth, and 74.5% of all freshwater are contained in the glaciers, which are not readily available for consumption. Freshwater is not distributed evenly, and in many regions around the world, such as the Sub-Sahara region and the Sub-Indian continent, water is seriously scarce or heavily contaminated. Freshwater plays an important role in the biological system and are used in many human activities: drinking, recreation, industry and most importantly, food production.

The combination of beauty and utility is our common, human art. It seems to me that natural building, and particularly earthen building, restores that relationship” Kiko Denzer Could Composting Toilets Save Cities Millions in Waste Water Treatment? Image credit: Biolet From the humanure approach of pooping in a bucket to the rough-and-ready "tree bog" composting toilet, I've posted plenty of low tech DIY options for dealing with human waste. But my fellow TreeHugger writers, to their credit, have often had more ambitious, mainstream plans for saner sanitation. From large office buildings going "off pipe" with composting toilets to the notion that high-tech composting toilets may be coming to our cities, these are tantalizing hints that our bodily waste may finally be seen for the valuable resource they are.
