Solar powered stove using 100% recycled materials This is an exercise in recycling and alternative energy use. I used a discarded 62 inch satellite dish and used CD's to create this along with materials that I had laying around. Nothing was purchased for this project. Step 1: Making the base/stand I did not have the base, so I made one from 3" ABS plastic pipe inserted in the ground about 18". Steven Harris on Making Alcohol Based Fuels at Home Steven Harris from IMakeMyGas.com Did you know that you can legally and inexpensively make your own alcohol based fuels at home. Today Steven Harris joins us to discuss doing just that! We start off with the easiest method by using sugar and move onto ways to cut the cost to almost nothing such as getting left over bread, cola syrup, old doughnuts, etc as feed sources for your yeast. Steven is also giving away five free copies of Alcohol Can Be A Gas by David Blume which the absolute bible on making your own alcohol based fuels. You can enter that contest at IMakeMyOwnGas.com
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.” I-Teams, (short for “Innovation Teams”) is a unique MIT course that assembles cross-disciplinary teams of students from across MIT. Big Frog Mountain- Voltage Drop & Max Ampacity Charts- Solar Power NEC allows rounding up cable ampacity to next standard fuse or breaker. Other factors will need consideration for proper conductor sizing including local codes and conditions. Always consult with and use a qualified electrician for any electrical work.

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. We’ve been featured in dozens of publications and programs including The New York Times, The Economist, The Wall Street Journal, Huffington Post, USA Today, Marketplace, Wired, and GOOD Magazine.
How I built an electricity producing Solar Panel Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. In my attempt to escape city slicker yuppies (you know the kind, the ones that like to blab loudly on their cell phone while they work on some business administration degree in a cyber cafe somewhere in Trendyland.) and their light pollution, I found a great piece of remote property.
Turbo 500-Mozilla Firefox Details We are currently out of stock of the T500 but we're expecting stock around the 10th of April. We're still accepting orders and will dispatch these on a first come first served basis. We are now stocking the new & improved T500. Operating the T500 is now easier than ever thanks to the fact there is only one thermometer to keep an eye on. 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: Your investment will help us develop and test new sustainable building and design techniques which we will share with the world via our website.
How this 12inch miracle tube could halve heating bills Last updated at 21:09 15 September 2007 It sounds too good to be true - not to mention the fact that it violates almost every known law of physics. But British scientists claim they have invented a revolutionary device that seems to 'create' energy from virtually nothing. Their so-called thermal energy cell could soon be fitted into ordinary homes, halving domestic heating bills and making a major contribution towards cutting carbon emissions. Scroll down for more... Even the makers of the device are at a loss to explain exactly how it works - but sceptical independent scientists carried out their own tests and discovered that the 12in x 2in tube really does produce far more heat energy than the electrical energy put in.
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. I've just come across an important editorial that suggests public opinion may be catching up on the subject, arguing for a serious look at community-wide composting toilets instead of building a new waste water treatment plant.
Windbelt Micro-wind, 10 Times Cheaper Wind Energy!! [Run time: 2:05 min] I hope you enjoy this short video of Shawn Frayne, a young inventor that has created this device to generate, on the micro-scale, energy for LED lights and radios in developing countries. This is the first approach that uses aeroelastic flutter to create super cheap electricity. We’re talking about changing the way wind energy is harvested and captured. Frayne won a 2007 Breakthrough Award from Popular Mechanics, and he deserves it. This incredible technology is 10-30 times more efficient than the best micro-turbines. So, Frayne hopes to fund third-world distribution of the Windbelt through sales in first-world applications.
Four Amazing Green Greenhouses Built 40 Years Ago By Michael Jantzen All images credit Michael Jantzen Artist and designer Michael Jantzen is best known for his visionary building ideas like his M-House, covered recently in Fast Company, but I was really excited by his older stuff like his Autonomous House, that I called a Thirty-year old green wonder. Trolling the older work on his site, I found some amazing looking greenhouse structures, and called him to find out more. What he built and what he said is really remarkable.
C:\IMAGES\OMNIPAGE\DATA\hm2.htm In collaboration with Norman Rostoker from UC at Irvine, we have designed a novel type of fusion reactor, the Colliding Beam Fusion Reactor (CBFR). It uses protons (p) and boron-11 (11B) for fuel. Fusion reactions produce only three helium-4 (4He) nuclei, and nearly 9 million eV energy.
