...wind turbines and now we have seen a marriage of the two. That's right, appropriate technology enthusiasts, there is a portable wind turbine on the horizon and it's perfect for charging your electronic gizmos. Skajaquoda is a research group based in Minnesota, USA, focused on developing products that can restore the ...

...wind turbines we have seen that aren't just anecdotal and where someone is serious about harvesting wind power, are generally seated on a tower or pole way above any obstructions in close proximity. Looking like an extra from a Star Wars movie, this small wind turbine for domestic use is, well, different ! An...

...wind turbine he could use to provide supplemental water heating. Applied Sciences then decided to make the design widely available to others along with an introduction to wind power, hoping that others might improve the design and functionality. Hence the beauty of open source design. The freely downloadable construc...

...wind and solar, is that it is unpredictable. This presents a challenge to grid operators, as they struggle to meet demand while compensating for calm winds or clouds. One method of balancing supply and demand that is garnering some attention lately, is pumped storage hydroelectric power stations. The concept is quite...

...wind, very low embodied energy. They make for a beautiful, authentic and natural looking roof. As it is a completely natural material, it can be more responsibly disposed of than other materials at the end of its life Cons: Installation is time consuming, hail can cause splitting of shingles, they aren’t permitted ...

...window gives you an incomparable view of the surrounding nature, which can also be enjoyed from the large bath on wheels rolled out on the terrace. It comes equipped with an entertainment system, pedal away on the stationary bike and watch all you want. Multi-use spaces that can convert from one use to another with l...

Bullfrog’s green electricity comes exclusively from wind and hydro facilities that have been certified as low impact by Environment Canada under its EcoLogoM program. Their natural gas is presently sourced in Quebec by collecting methane escaping from a landfill site. A common question seems to be "How do they ensur...

...wind turbines: Zoetrope home wind turbine by Applied Sciences The problem here is trees! It's recommended to ensure that a wind turbine is taller than any other structure or tree within 100 metres. The wind patterns of your geographical location would be the first thing to investigate in determining whether o...

A project started in 2002 by Verdant Power Inc. saw tidal turbines placed 10 metres deep in the East River of New York, taking advantage of the reliable tidal surge of Long Island Sound. Spinning silently at 35-40 rpms for 18 hours a day in a 4 knot current, tidal turbines eliminate two of the more common complaints...

...wind turbine and 600W solar outputs that enable it to operate completely off-grid. A dual-power system offers an additional source of electricity during periods without sufficient sunlight or wind. The structure’s rounded shape also helps to easily collect rainwater, which is then purified with a built-in filtration ...

...wind-up devices. There are head lamps and even LED lanterns that can operate for hours or more on a single wind, however, to ensure a strong battery, you should wind them to full power on occasion rather than letting them sit there dead. Candles and functioning lighters are a great back up, but even safer are battery...
