How I built an electricity producing wind turbine 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. I found a great piece of property. One thing I noticed right away about my property is that most of the time, the wind is blowing. Let me state up front that I probably won't be able to help you out much if you decide to build your own wind turbine. Since no one seems to be reading the FAQ, I will answer the No. 1 question I get many, many times a day right here up front. Update: Here is a video of the wind turbine in operation. Update: Here is a video of me assembling and setting up the wind turbine on my remote off-grid property. I started the process of designing my wind turbine by Googling for information on home-built wind turbines. A generator Blades A mounting that keeps it turned into the wind A tower to get it up into the wind Batteries and an electronic control system . Finally!
Building Integrated A mixed-use project in Chicago has been getting a lot of attention for its green elements. Most noticeable, perhaps, is the beveled corner that holds 12 vertical-axis wind turbines (VAWT) by Helix Wind. The turbines are stacked in two columns on the building’s southwest corner and were included in the HOK designed-facade to cover all exterior lighting costs. If successful, Greenway could pave the way for similar installations in all kinds of buildings, including future condo and multifamily projects. Helix S594 is the aluminum turbine used in this structure and it retails for about $16,000. Each turbine measures 16′x4′ and weighs approximately 1,330 pounds. Credits: Flickr/John Picken.

17 Apart: Growing Celery Indoors: Never Buy Celery Again Remember when we tested and shared how to grow onions indefinitely last week? Well, at the same time, we've been testing out another little indoor gardening project first gleaned from Pinterest that we're excited to share the successes of today — regrowing celery from it's base. We've figured out how to literally re-grow organic celery from the base of the bunch we bought from the store a couple weeks ago. I swear, we must have been living under a rock all these years or just not be that resourceful when it comes to food, but we're having more fun learning all these new little tips and tricks as we dive deeper into trying to grow more of our own food. This project is almost as simple as the onion growing project — simply chop the celery stalks from the base of the celery you bought from the store and use as you normally would. We let our celery base hang out in the saucer of water for right around one week, give or take. Update 2: Here's how we are looking at almost 3-4 weeks of growth:
Home Page An educational 3 phase turbine kit. Comes with everything you need to create a 3phase wind turbine. Great for science projects, learning about 3phase PMG alternators, and alternative energy. The kit includes 6 very powerful neodymium magnets. Check it out! The original 6 ft turbine with a car alternator and chain drive. The downwind turbine, a very small but quite efficient little unit. One of the original alternator modifications. Old projects that may be of interest Comes with everything to assemble it as shown As a dedicated "do it yourselfer" I put this site up for all those who share similar DIYS skills and convictions. I hope what I have here helps you in your endeavors in some way, big or small. This site is maintained using windpower and Solar. Thanks for dropping by and Welcome !
Skystream 600 Southwest Windpower, maker of the Skystream 3.7, unveiled a new version of the popular turbine at CES 2011 called Skystream 600. The turbine features an improved design with larger blades, enhanced software, and an improved integrated inverter. And, according to a press release, Skystream 600 will be the “first fully smart grid-enabled wind turbine” on the market when available in April 2011. With the improvements, Skystream 600 is estimated to produce about 74% more energy than Skystream 3.7. These numbers are pretty good — about 60% of an average American’s home energy needs — but everything depends on siting, wind conditions, tower height, and several other factors. Skystream 600 comes with the internet-accessible Skyview system showing users how much energy is produced in real time. [+] More info on the Skystream 600. Credits: Southwest Windpower.

The Universal Principles of Sustainable Development By Terry Mock and Tony Wernke, SLDI Co-founders Follow Terry and Tony on Twitter: Terry @SustainLandDev; Tony @Sustainable4U This article is Part 3 in the Fractal Sustainable Development Trilogy. Part 1: Designing a ‘Big Wheel’ for Civilization Part 2: Like Life Itself, Sustainable Development is Fractal As a comprehensive sustainable development decision model, The SLDI Code™ functions as a completely integrated, fractal matrix which leads decision-makers from the foundation of triple-bottom-line sustainability to sustainable results. NOTE: The principles embedded in the SLDI Code Sustainable Development Matrix are universal in their application and need not be confined to land development projects. The SLDI Code is not designed to replace or compete with other more narrowly defined programs or regulatory constraints. The SLDI Code™ Sustainable Development Matrix The SLDI Code Sustainable Development Matrix begins with the three bottom lines necessary for sustainable project development.
Wind and Water Power Program: Wind Powering America Swift Wind Turbine About SWIFT The SWIFT Wind Turbine is a structure or pole-mountable wind turbine that generates electricity by harnessing the power of the wind. With unique, patented technologies the SWIFT provides unprecedented safe, efficient, and near silent operation. The team of engineers behind SWIFT has a passion about providing safe, clean energy for everyone. The emphasis of the SWIFT design has been focused on safety, reliability, and ease of operation, alongside the high-performance of this innovative system.

What is Sustainable Development? CanWEA Wind Lens - Japón por Raul Mannise · 31/08/2011 Yuji Ohya, un profesor de la Universidad de Kyushu, ha presentado en el marco de la Exposición Internacional de Energías Renovables realizada en Yokohama (Japón), un nuevo tipo de generador eólico. El concepto puesto a punto por Ohya se llama “Wind Lens” y consiste básicamente en una turbina embutida en una estructura con forma de aro que hace las veces “lente” capaz de intensificar el flujo del viento que incide sobre ella. Según sus creadores, este dispositivo será capaz de triplicar la energía obtenida con respecto a los generadores eólicos tradicionales. Si los cálculos efectuados por Yuji Ohya son correctos, Japón podría reemplazar algunos de sus reactores nucleares con “granjas eólicas” basadas en estas turbinas. Japón fue duramente golpeada por las olas del tsunami originado por el terremoto que sacudió sus costas a principios de este año. Por ahora “Wind Lens” no es más que un concepto, y su creador aún no ha decidido su comercialización.
