Using Energy From Kites

Greener Living Is The Name Of The Game

By guest writer, Donna, of the Kites Club website.

More and more of us are re-thinking our life choices and habits trying to become greener and more environmentally friendly.

This is happening on a household level as well as a national and global level. One of the biggest challenges is finding alternative energy sources of the green kind. In other words, harnessing nature to our advantage without creating havoc while doing this.

Lately big power kites are being used to harness the enormous amounts of energy hidden in the winds. At 30,000 feet the wind energy is twenty times more than it is at sea level. At Delft University of Technology in The Netherlands, researchers are taking advantage of this energy from kites with the help of a laddermill.

Energy from kites - a laddermill

The laddermill consists of a large number of kites which move in an upward and downward motion. These kites are really a combination of kites and airplanes. The kite can climbs with relative ease but needs a force pulling its cable to descend. Airplanes are the exact opposite, requiring a large engine to ascend. Descending is easier, since it pretty much just glides down.

The kites on the laddermill combine the ascending characteristics of a kite and descending characteristics of an aircraft. By creating a large loop of 'kite-planes' a rotation is formed. Coupled with a generator, this can create energy. Laddermills could potentially go up to 30,000 feet, being able to generate approximately 100MW of energy.

This could potentially power about 100,000 homes, relatively inexpensively. All of this is still in the developmental stages, though energy from kites is now way past the stage of theory.




E-book special of the month (25% off)...

The Dopero is someone's clever idea to combine 2 Roller kites! Double Pearson Roller is where the name comes from. The resulting flat portion of sail in the middle makes this a very efficient design in light wind.

Even more so than the Roller before it, this kite has an attractive aircraft-like appearance in the air. This MBK version also excels in light winds.

If you have made Diamonds before, this kite takes somewhat more time to make. With the help of my instructions, it's still do-able by a beginner.

Get the e-book for making the MBK Dowel Dopero kite. After making your first one in plastic and seeing how it performs, you can try soft Tyvek or rip-stop nylon for your next build.

This Dopero can fly in quite a wide range of wind speeds thanks to the 4-pont bridle. The bridle lines keep the frame more rigid than a 2-point bridle could. Tail(s) are entirely optional, but may be added for looks.

The e-book is a PDF file - which means printable instructions to refer to while you make the kite. It also means convenient off-line access if that suits you better.

    This knot doesn't have the greatest reputation - but it's simple and does have it's place in some less-critical kiting scenarios. Usually with the addition of a drop of glue ;-) ...

"Love the easy to understand step by step instructions, made from next to nothing materials and above all so much fun to fly... cheers Tim for sharing your well thought out pdf kite designs with the whole world.

Very satisfying making your own and watching them get air-born for the first time."

"30+ years ago, I tried making a kite using the 'instructions' in a free kite-safety booklet. What a disappointment for a young boy.

 Your instructions and methods are wonderful. You help the builder to focus on accuracy, without making it hard. Also, you use materials that are durable, yet cheap!"
