more power. The size of the window grows in direct proportion to the
increased length of the lines. Given that the circumference of a circle = 2
* pi * radius, then if the power window is 45 degrees (on one side) and you
have 20 meter lines, the length of the window arc (at the water line,
technically) = 2 * pi * 20 * (45/360) = 15.7 meters. With 30 meter lines,
the window arc is 23.6 meters.
So, the expanded size of the wind window gives the kite greater traveling
distance. I think this allows the kite to continue accelerating for a
longer time than in a smaller window because it is staying in the power
zone for longer. A longer acceleration time means greater kite speed, which
means greater apparent wind speed, which would therefore create more power.
At least, that's my thought!
