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.
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)...
e-book takes you step-by-step through making a 120cm (4 ft) tall
Parafoil kite. This 4-cell kite performs best in gentle to moderate
wind speeds. That's 12 to 28kph or 8 to 18mph. Even in light
winds, this kite will hang in the air, although at 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 Parafoil 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.

Or Tube Men or Sky Dance Puppets or a raft of other names. Everyone's seen one flailing away somewhere. Find out a bit more about these hilarious air-driven things at this previously published page!
