How To … BUILD A SOLAR PANEL W/ … SODA CANS [VIDEO If you’ve got good sun exposure on one side of your house, you can take advantage of free heat from the sun with this DIY solar heating panel, which uses old soda cans to collect and transfer the sun’s energy into your house. Sometimes, low-tech solar devices are much better than high-tech ones for home use, as they not only tend to be cheaper to make, but will also last much longer before any repairs or maintenance are necessary. And even better, they can be built in part from repurposed or recycled components, which is something you don’t see very often in new solar devices. This solar space heater design uses old soda cans to increase the surface area for heat transfer inside of it, and in its most basic design, uses no external power to move the air.
This glass sphere might revolutionize solar power on Earth German architect André Broessel, of Rawlemon, has looked into his crystal ball and seen the future of renewable energy. In this case it’s a spherical sun-tracking solar energy-generating globe — essentially a giant glass marble on a robotic steel frame. But this marble is no toy. It concentrates both sunlight and moonlight up to 10,000 times — making its solar harvesting capabilities 35 percent more efficient than conventional dual-axis photovoltaic designs. DIY Residential Wind Generators DIY Wind Generators I made two wind generators, one was a motor from a stair master and one was from a tread mill. The third wind generator I bought.
DIY Solar Battery Charger - Maximizing Your Solar Power Output You can easily maximize your solar power output during the summer when solar power is more readily abundant. Even a simple 6 volt solar cell can give you an easy way to take advantage of abundant sunlight and help you double the output of your solar cell. Most conventional usage of a six volt solar cell is for either charging a spotlight battery or to run a deer feeder but you can use it to charge AA or even AAA rechargeable batteries which are commonly used in a variety of other devices.
In Maryland, tiny houses that are a little bit Tolkien, a little bit Thoreau Today, here’s a quick look at an outfitter of custom tiny homes out of bucolic Garrett County, Maryland, that specializes in creating pint-sized structures that “speak to the art of the small building movement” while incorporating an impressive amount of reclaimed, recycled, and locally sourced building materials and architectural elements. And given that the design/build firm in question is named Hobbitat and its homes are referred to as “Waldens” — alternately known as “Hobs” — this is one company that clearly wears its literary inspirations on its sleeves. A relative newbie on the tiny home building scene that’s already received props from tiny house demigod Jay Shafer, Baltimore refugee and historic restoration specialist Bill Thomas and his wife, Sue, established Cranesville-based Hobbitat in the beginning of 2012 as a spin-off of their “normal sized” custom home building business, Blue Sky Ventures. And then there’s the Blue Moon Rising Center for Sustainable Education.
Heat Your Room For 15 Cents a Day Heat Your Room For 15 Cents a Day The following video shows us an ingenious way to heat a whole room for under 15 cents or possibly even cheaper if you find cheaper candles or maybe larger ones. It’s simple, here’s what you need:
How to make a solar PAL kit - a new eco-guide for everyone ! by eco-solar About this project Risks and challenges As the hard bit is already done The only risks in completing the project on time are a delay in the reproducing/ printing process( should the project really take off) should this be the case I have other printer/ dvd reproduction firms in hand to complete this process successfully.

Here are some of our favorite dispatches from Kirsten’s travels. Teen builds tiny house for a mortgage-free future When Austin Hay began contemplating leaving home, he decided he didn’t want to live in a dorm, or save for a 3,000-square-foot home with a two-car garage.
One cheap solar panel at a time I buy one cheap solar panel at a time. I live on a very tight budget. I started out with the harbor freight solar panels. The two smallest solar panels are 10 watts each. The big blues are 245 watts each. They were the best priced yet and I spent my Christmas bonus on them. spherical glass solar energy generator by rawlemon aug 25, 2012 spherical glass solar energy generator by rawlemon spherical glass solar energy generator by andre rawlemon german born, barcelona-based architect andré broessel has sent us images of his latest development of a spherical glass solar energy generator. the project uses the advantageous strategy of implementing a ball lens and specific geometrical structure to improve energy efficiency by 35%. in contrast to its traditional photo-voltaic ‘dual-axis’ counterparts, the device incorporates a fully rotational weatherproof natural optical tracking device that is adequate for functioning on inclined surfaces and curtain walls, empowering any building surface. the new solar generating concept has capabilities that concentrate diffused daylight or moonlight for a more effective site context application. left: second prototype showing light transmission through 3 ball lenses right: second prototype showing performance in different light diffusion situations rodrigo caula I designboom
Environmental Advantages of Green Rooftops .ads in wordpress (by livingroofs.org) 1. Air Quality easy solar starter kit My solar starter kit was a cheap little solar panel and I had a battery siting in the garage. I used a diode so the panel wouldn’t drain the battery at night. That’s what I started with. The next item I purchased was a solar battery charge controller. This little gadget will give your battery a proper charge. It won’t over charge your battery.
