Among these: Beaufort created the Beaufort cipher. It is a substitution cipher similar to the Vigenère cipher.

History of wind power turbines off Fukushima by 2020" at a cost of some 10-20 billion Yen. Airborne wind energy systems use airfoils or turbines supported in the air by buoyancy or by aerodynamic lift. The purpose is to eliminate the expense of tower construction, and allow extraction of wind energy from steadier, faster, winds higher in the atmosphere. As yet no grid-scale plants have been constructed. Many design concepts have been demonstrated. History of wind power Wind power has been used as long as humans have put sails into the wind. For more than two millennia wind-powered machines have ground grain and pumped
