  • Flexible kite
    Patent number: 7533851
    Abstract: A kite is formed of a single sheet of tough but flexible material. A narrow slit in the sheet body defines two distinct flight bodies, one of which is substantially smaller than the other. The smaller forward flight body is elongated and joins the larger flight body at the smaller portion's ends. The kite requires no rigid support structures and is capable of stable flight at very low wind speeds.
