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.

Click to get 'Making The MBK Parachute Kite'

This printable e-book takes you step-by-step through making a 119 cm (4 ft) wide Parachute kite. It's not quite that wide in the air since the canopy takes on a distinct curved shape when inflated. This 14-cell kite performs best in moderate to fresh wind speeds. That's 20 to 38 kph or 13 to 24 mph. In gentle winds, this kite will hang in the air at fairly low line angles. In fresh winds, it pulls firmly for it's size, so small kids should only fly it while supervised!

Every kite design in the MBK Soft Series satisfies the following points...

  • Materials are plastic sheet, tape and line – and nothing more!
  • Tools are a ruler, scissors and a marker pen - and nothing more!
  • All cuts are along straight lines.

For the greatest chance of success, I make recommendations regarding the materials. For example, the type/weight of plastic, type/width of tape and line type/strength. Close enough should nearly always be good enough, since the design is well-tested and should be tolerant of small differences from my original.

Get the e-book for making the MBK Parachute 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.

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.

Testimonials

"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 decided to run kite making as an elective again on this camp in the past week - so I bought all your e-books, a bunch of materials, and then took a group of 10 high school students through making the kites over 4 days. We built a diamond, a Barn Door, a Delta, and two skew delta kites. Again - every single kite flew."

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!"
