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...


I've been making and flying traditional-style
Box Kites on-and-off ever since this site was started...

Get the e-book for making a range of bamboo or dowel designs. Down to $7 from the usual $9.95, for this month.

With a large range of wind speeds covered, not to mention a large choice of kite size to attempt, the ideal box kite for you has to be in there somewhere!

My personal favorite would have to be the giant 2.4m (8ft) long Multi-Dowel Box which flies steep and steady. It's on the e-book cover over there...

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.

"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."

"I've just bought your super e-book and spent most of last night pouring through all the great stuff in it!

Very detailed and USEFUL information - thanks for such a great book."

"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!"
