Wind Spinners

 

During the 18th interval tailless bowed kites were still unknown in Europe. Flying planate arch- or pear-shaped kites with tails had become a popular pastime, mostly among children. The first recorded random application of a kite took place in 1749 when Alexander Wilson of Scotland used a kite train (two or more kites flown from a common line) as a meteorologic device for measuring temperature variations at different altitudes.

Kites Wind Spinners can be fanatic for radio purposes, by kites carrying antennas for MF, LF or VLF-transmitters. This method was acclimated for the reception station of the first transatlantic transmission by Marconi. Captive balloons may be more convenient for such experiments, because kite carried antennas require a lot of wind, which may be not always possible with heavy equipment and a ground conductor. It must be taken into play-by-play during experiments, that a conductor carried by a kite can front rank to a high voltage toward ground, which can endanger people and equipment, if befitting precautions (grounding through resistors or a parallel resonant-circuit tuned to transmission frequency) are not taken.
