More than two centuries after Benjamin Franklin used one to study lightning, a team of atmospheric scientists has found that kites are a potent research tool for studying air conditions at high altitudes.
Ben Balsley and John Briks at the University of Colorado have developed a kite and instrument package to sample the atmosphere up to 3.5 kilometers high, for up to two days at a time. The kite is cheaper and more flexible than balloons and aircraft, the traditional vehicles for atmospheric research. Within two years the team expects to fly kites up to 10 kilometers high, and Briks hopes to use these to measure carbon dioxide and methane emissions over the Brazilian rainforest and the transport of air pollutants over the Atlantic Ocean.
The kite is a 15-square-meter Para foil made of Mylar, which ’is not only strong, but unlike nylon, Joes not absorb water. The kite "string" is made of Kevlar, famous for its use in bullet-proo
